ABSTRACT The aim of this research work is to investigate the relationship between environmental performance and financial performance. In this study, a sample of 111 companies that are constituents of FTSE 250 index listed on the London Stock Exchange was used. The environmental data was gotten from ASSET 4 ESG database and the financial data was collated from FAME database. A quantitative method and OLS model were used in analysing the study. The results reflect a negative correlation for financial performance of the companies represented by ROA and ROCE and a positive correlation for financial performance of the companies’ proxy by Tobin Q. The study reflects that environmental performance plays an important role in financial performance which could be as a result of the economic benefits that can be derived from companies investing in environmental incentives, or can be as a result of the potential increase in profitability and market value of firms. Furthermore, this study also supports the Stakeholder Theory, Win win view, Resourced-based view and the Economist’s view which supports that there is a relatioship between environmental performance and financial performance.

CHAPTER ONE INTRODUCTION 1.1 Background of the Study The Brundtland Commission in 1987 buttressed the significance of sustainable development which was based on the idea of meeting the needs of the present generation without compromising the ability of future generations to meet their own needs (Brundtland 1987). This means adequately managing available and limited resources in order to reduce waste. Government, Companies and all Stakeholders need to ensure that both financial and environmental matters are taken into consideration when making business decisions, as most decisions are taken to improve the financial performance of companies and not the environmental performance of companies. In recent years, organisations in industrialised nations have embraced the idea of improving the environmental performance of their organisations due to the vested interest of their stakeholders and other interested parties. An increasing awareness of environmental problems brought about by economic activity has led to greater political and social demands on firms to reduce their environmental impact (Galdeano-Gómez et al., 2008). Managers, companies and government agencies are confronted with environmental issues and how they affect the environment. Managers, companies and government agencies are confronted with ways to improve environmental impact and performance (López-Gamero et al., 2009). In recent years, many stakeholders such as governments, employees, investors, shareholders and the community are more conscious about environmental issues, corporate environmental management and the impact of companies’ actions on the environment. This directly or indirectly influences the financial performance of firms (Iwata and Okada, 2011). The Paris Climate Change Agreement was drafted in 2015 by the United Nations Framework convention on Climate Change (UNFCCC). The goal of this agreement is to reduce global warming in all countries which is aimed at making finance flows consistent with a pathway towards low green gas emissions and climate-resilient development.

Amosun Olayemi .O 4632788 Industrialist and green activists are intrigued with the idea that steady improvements in environmental performance will lead to steady improvements in the financial performance of companies. As proven by various studies (McDaniel et al., 2000; Nikolaou et al., 2013; Achim and Borlea, 2014), in most cases no link has been found between the financial performance of a company reflected in the financial statement and the actual performance of the company reflected on the market. However, researchers have emphasised the need for companies to take into account both financial growth targets and other non-financial growth targets such as environmental, social and governance performances in order to maximize the company’s overall performance. Various researches to establish a relationship between environmental performance and financial performance have produced contradictory evidence (Russo and Fouts 1997; Konar and Cohen 2001; Takeda and Tomozawa 2004; Yamaguchi 2008; Jacobs et al., 2010; Mahapatra 1984; Jaggi and Freedman 1992; Takeda and Tomozawa 2004; Aupperle et al., 1985; McWilliams and Siegel 2000; Jayachandran et al., 2013; Primc and Carter 2015). Studies into the relationship between environmental performance and financial performance of companies have been ongoing for some years. However, there have been no conclusive results for various reasons. Early studies have been based on small samples, old data and various theories. Empirical studies have used various environmental and financial performance measures. However, some empirical studies have revealed that there is a positive relationship between environmental performance and financial performance (Russo and Fouts 1997; Yamaguchi 2008; Jacobs et al. 2010), while some studies revealed that there is a negative relationship between environmental performance and financial performance (Mahapatra 1984; Takeda and Tomozawa 2004). Although some research studies revealed that there is a neutral link between environmental performance and financial performance (Aupperle et al., 1985; McWilliams and Siegel, 2000), some studies also revealed that there is no relationship between environmental performance and financial performance (Jayachandran et al., 2013; Primc and Cater, 2015). Various theories postulated have been used to explain the link between environmental performance and financial performance. For example, the Agency
2|Page
Amosun Olayemi .O 4632788 Theory postulated by Jensen and Meckling (1976) suggests that the primary objective of a company is to maximize shareholders’ wealth. Friedman and Friedman, (2002) and Millton, (1970) asserts that the basic social responsibility of a business is to use its resources and engage in activities designed to increase its profits. A company that decides to improve on its environmental performance will incur more costs which will affect the maximization of the shareholders’ wealth. This does not conform to the objective of the theory. The theory therefore proposes that there is a negative relationship between a company’s environmental performance and financial performance. However, the Stakeholder Theory postulated by Freeman (1984) introduced some factors previously ignored in the Agency Theory. This theory suggests that different stakeholders such as public administrators, environment, customers, shareholders, employees and many more should be considered when making business decisions. Environmental issues and the impact of these issues affects all stakeholders. In a research carried out by Ruf et al., (2001) revealed that the findings provided a form of support for a section of the stakeholder theory that asserts that the dominant stakeholder group, shareholders benefit financially when management meets the demands of multiple stakeholders. The research findings showed that long-term financial benefits exist when environmental performance is improved. This theory therefore suggests that there is a positive relationship between environmental performance and financial performance. The Win-win scholars Porter and van der Linde (1995) suggest that properly designed environmental standards can trigger innovations that can lower the cost of production or improve its value which will help increase profit and the financial performance which makes companies competitive. This suggests a positive relationship between environmental performance and financial performance. The Resource-based view suggests that embracing the notion of improving environmental performance also requires a fundamental shift in a firm’s culture and human resources and the organizational capabilities required to manage them which improves a company’s performance. In a research carried out by Russo and Fouts, (1997) posited that environmental performance and financial performance are positively linked and that industry growth moderates the relationship. This view
3|Page
Amosun Olayemi .O 4632788 suggests a positive relationship between environmental performance and financial performance. The Economist’s view suggests that when assessing whether enhanced environmental performance will lead to increased profits, a firm must consider the effects of that change on the revenues and costs of the firm. In a research carried out by Erfle and Fratantuono (1992 cited by David Edwards, 1998) concluded that environmental performance was positively correlated to financial performance measured by return on assets, return on equity and return on investment. This view suggests a positive relationship between environmental performance and financial performance. The neoclassical theory argues that environmental regulation imposes additional costs for firms. The theory further argues that improved EP leads to an increase in costs. This view is based on the premise that pollution abatement and environmental improvements have decreased marginal net benefits. This view is in contrast with Win-Win view that believes that environmental initiatives will systematically increase profitability. The idea is seen as unrealistic (Palmer et al., 1995, pp.119-132; Walley and Whitehead, 1994 cited by Horváthová, 2010). This view therefore suggests a negative relationship between environmental performance and financial performance. Companies have recognised the need for sustainability (environmental) reporting and are voluntarily managing and reporting on the impact of their activities on the environment. Although there are various disagreements on the relationship between environmental performance and financial performance, recent theories and research have shown that there is a positive relationship between environmental performance and financial performance. Several studies have analysed the link between environmental performance and financial performance (Horváthová 2010; Iwata and Okada 2011; Horváthová 2012). However, majority of the previous studies were carried out in the US, with little studies conducted in Australia, Japan and Romania. Thus in contrast, this research work examines the relationship between environmental performance, as measured by environmental performance index and financial performance of FTSE 250 companies in the UK during the years 2013 and 2014. 4|Page

1.2 Justification Various scholars and researches have conducted researches on the relationship between environmental performance and financial performance; however, some of the results have been inconclusive. Some researchers have found a positive relationship (Russo and Fouts 1997; Konar and Cohen 2001; Takeda and Tomozawa 2004; Yamaguchi 2008; Jacobs et al. 2010) and there are others that have found a negative relationship (Mahapatra 1984; Jaggi and Freedman 1992; Takeda and Tomozawa 2004). However some researchers found a neutral link between environmental and financial performance (Aupperle et al. 1985; McWilliams and Siegel 2000), whereas others have found no relationship in any way (Jayachandran et al. 2013; Primc and Cater 2015). The results have been different because various environmental performance and financial performance measures have been used. Some of the financial performance measures that have been used in existing literature are Tobin’s Q (Konar and Cohen 2001; Jayachandran et al. 2013), ROA (Ahuja and Hart 1996; Russo and Fouts 1997; Nakao et al. 2007), ROE (Ahuja and Hart 1996; Nakao et al. 2007). There have been various limitations in the existing research as a result this research aims to contribute to existing research and aims to explain the relationship between environmental performance and financial performance as majority of the previous research have been conducted in the US, Australia and very little research has been carried out in the UK. There have been various environmental performance measures and financial performance indicators which have produced different results. The study looked at companies’ environmental performance in relation to the companies’ Tobin Q ratio, return on assets [ROA] and return on capital employed [ROCE]. The study covered periods 2013 and 2014.

CHAPTER TWO LITERATURE REVIEW 2.1 Introduction Various researchers, stakeholders, managers and the world at large have been interested in environmental issues such as global warming, pollution, biodiversity, ozone depletion, deforestation, and waste issues for a while. Researchers often ask how environmental performance affects financial performance of companies. Does better environmental performance improve a firm’s financial performance? In seeking to answer the question on the relationship between environmental performance and financial performance and the impact of environmental performance on a company’s financial performance, many studies have been conducted from different perspectives (Iwata and Okada 2011). Various researchers have investigated whether the environmental decisions companies make pays off financially. Researchers have questioned if it pays to be green. In economic literature, environmental problems have traditionally been treated as inconsistencies between social and private benefits and have mainly been left to government intervention to solve them. However, if financial performance is positively related to environmental performance, firms have incentives to reduce their environmental damages. This means that environmental problems may be solved by the market mechanism without government intervention, leading to a preferable environment for both firms and the government (Iwata and Okada 2011). Several researchers have found a positive relationship (Russo and Fouts 1997; Konar and Cohen 2001; Takeda and Tomozawa 2004; Yamaguchi 2008; Jacobs et al. 2010) and there are others that have found a negative relationship (Mahapatra 1984; Jaggi and Freedman 1992; Takeda and Tomozawa 2004). However, some researchers found a neutral link between environmental and financial performance (Aupperle et al. 1985; McWilliams and Siegel 2000), whereas others have found no relationship in any way (Jayachandran et al. 2013; Primc and Cater 2015). Bhat (1990) carried out an analysis to examine the relationship between environmental performances and financial performances of large US companies. The 8|Page
Amosun Olayemi .O 4632788 author used a sample of 230 companies. The analysis indicates that companies generating lower pollution secure higher profit margins and higher stock market values. Investors are willing to bid up prices of companies that generate less pollution because they generate higher profits at a lower risk. Also, Filbeck and Gorman (2004) researched on 24 firms; the study revealed that there is no positive relationship between environmental performance and financial performance. The results differ as there is no positive relationship between holding period returns and an industry-adjusted measure of environmental performance. There is a negative relationship between financial return and a more pro-active measure of environmental performance. Primc and Carter (2015) on the other hand, analysed 27 Australian firms and the result of the analysis implied that environmental proactivity is not always associated with high firm (financial) performance, and that environmental proactivity is not as important as important as the other conditions for high-performing firms in high polluting industries.

that

(environmentally) responsible investment funds perform no better than no-socially screened funds and many relatively responsible companies have not been financially successful. This shows that there is no relationship between environmental performance and financial performance. There have been various inconclusive results on the relationship between environmental performance and financial performance. Research into reasons why there have been inconclusive results concluded that various environmental and financial performance measures, time span, sectors, industries, sample size, countries and methodologies were used resulting in various results (Konar and Cohen 2001; Wagner et al. 2001; Filbeck and Gorman 2004; Horváthová 2010).
2.2 Environmental Performance Corporate environmental performance (CEP) has been of fundamental interest in scholarly research during the last few decades. During the last few decades, corporate environmental performance (CEP) has been the subject of considerable interest among organizational research scholars (Trumpp et al., 2013). 9|Page
Amosun Olayemi .O 4632788 There have been limited numbers of articles and books that define environmental performance as articles and books looking into the relationship between environmental performance and financial performance have focused on the links and results. ISO defined environmental performance as environmental results achieved whenever the environmental aspects of activities, processes, products, services, systems, and organisations are managed and controlled. Environmental performance is believed to be improved whenever the environmental aspect mentioned above are managed and controlled and whenever harmful environmental impacts are reduced and beneficial environmental impacts are produced. Waste management (2016) defined environmental performance as consuming less water, less energy, and natural resources while producing green space for wildlife and renewable energy in services for our customers. Emitting less by lowering emissions and having fewer releases to water, land and air and encourage recycling and achieving financial objectives. Environmental

Environmental performance is the minimisation of the negative repercussions on the natural environmental that stems from the productive activities of a company and the social perception of this impact (de Burgos Jiménez and Céspedes Lorente 2001). Lankoski (2000 cited by Salem et al., 2011) defined corporate environmental performance as “the level of harmful environmental impact caused by a firm so that the smaller the harmful environmental impact the better the environmental performance and vice versa”. Furthermore, Wagner (2003 cited by Salem et al., 2011) defined corporate environmental performance as “the results of an organization‟ management on its environmental aspects” EP can basically be conceived as the extent to which companies meet the expectations
of

regarding
environmental
responsibility.
Accordingly, EP is considered a multidimensional construct that does not only include environmental outcomes and impacts on the company, its stakeholders and the environment but also principles of environmental responsibility and processes of 10 | Page
Amosun Olayemi .O 4632788 environmental responsiveness which determines future outcomes and impacts (Ruf et al., 1998; Carroll, 2000 cited by Schultze and Trommer, 2011, pp.375-412). EP can be defined as ‘a business organization’s configuration of principles of social responsibility, processes of social responsiveness, and policies, programs, and observable outcomes as they relate to the firm’s societal relationships’ (Wood, 1991 cited by Orlitzky et al., 2003).
2.3 Environmental Performance Measures Measuring environmental performance is a key challenge facing corporate environmental managers. Without accurate measures of performance, it is difficult to set priorities, track progress, analyse problem areas, or create incentives and reward performance (Wells, Calkins and Balikov, 1994). Various environmental performance indexes have been used in explaining the relationship between environmental performance and financial performance by various scholars and researchers. Corporate environmental performance indicators are usually divided into three main categories: 1) environmental impact (toxicity, emissions, energy use, etc.); 2) regulatory compliance (non-compliance status, violation fees, number of audits, etc.); and 3) organizational processes (environmental accounting, audits, reporting, Environmental Management System, etc.) (Ilinitch 1998; Lober 1996; Wood 1991 cited by Delmas and Blass 2010). Some researchers have used firm’s environmental ratings provided by independent organisations, environmental reports issued out by companies, environmental key performance indicators such as waste, greenhouse gas emissions, carbon emissions, energy consumption, paper consumption, water consumption, some studies use only environmental management variables (González-Benito and González-Benito 2005; Wahba 2008), others use only environmental performance variables (Al-Tuwaijri et al., 2004; Wagner 2005 cited by López-Gamero et al., 2009), and a few papers have used both environmental management and environmental performance variables jointly (Judge and Douglas 1998; King and Lenox 2002; Link and Naveh 2006). However, for this research work, the environmental performance measured to be used is the environmental performance score from DataStream. 11 | Page

2.4 Corporate Financial Performance Corporate Financial performance is defined as “financial viability, or the extent to which a company achieves its economic goals (Price and Mueller 1986, quoted by Orlitzky et al., 2003, cited by Fischer and Sawczyn, 2013). Although there have been no adequate definitions and arguments on the definition on FP, there have been disagreements on the best method to measure CFP (Boaventura et al., 2012). Financial performance is commonly used as an indicator of a firm's financial health over a given period of time. The financial performance of a firm can be defined or measured in various different ways. Each of these different measures captures a slightly different aspect of financial performance. Some, such as profitability, gauge return; others, like sales growth and market share growth, gauge the growth of a firm. Some measure profitability (return on investment, return on equity), some liquidity (quick ratio, current ratio), and still others solvency (gearing). Some measures are indicators of commercial success (growth, market share) while others are indicators of financial success (profitability). In this regard it can also be argued that different firms have differing financial goals and therefore one financial performance indicator need not measure the success rate as perceived by the firm itself (Vijfvinkel et al., 2011).
2.5 Financial Performance Measures and Dependent Variables. There are various methods and ways a company’s financial performance can be measured. However, the most commonly used methods of measuring financial performance by scholars and researchers alike are the accounting-based measures and the market-based measures. The accounting-based measures and market-based measures will be used in this research work. The accounting-based measures commonly used are ROA, ROCE, Return on sales, Return on Equity, Growth ratio, Reputation. However, the accounting-based measures to be used in this work are Return on Asset [ROA] and Return on Capital Employed [ROCE]. The market-based measures commonly used are Market Capitalization, Price to book ratio, dividend yield, Tobin’s Q. However, the market-based measure to be used in this work is Tobin’s Q ratio. 12 | Page

2.5.1 Return on Asset [ROA] as a dependent variable. Various researchers have used ROA as an accounting-based measure of financial performance (Ahuja and Hart 1996; Russo and Fouts 1997; Iwata and Okada 2011; Moneva and Ortas 2010; Nakamura 2011; Goll and Rasheed 2013; Achim and Borlea 2014; Ong et al., 2014; Muhammad et al., 2015). However, some have found a positive correlation while some have found a negative correlation. Achim and Borlea (2014) conducted a study on 76 Romanian companies to evaluate the link between environmental performance and financial performance. The authors’ results revealed a negative correlation for the ROA and a positive correlation for Tobin’s Q. The study attested that environmental investments are not immediately reflected in an increase in the companies’ internal performance but rather in an increase in investment costs and a decrease in assets’ efficiency. For investors, these investments in environmental activities are appreciated as “good news” and as a factor that will ensure long-term sustainability of the company. The authors hypothesised that an increase in a company’s environmental performance contributes to an increase in a company’s financial performance. However, the hypothesis was rejected as the study attests a negative relationship between EP and ROA, which shows that the adoption of CSR activities is not directly reflected in an increase of the company’s ROA. Russo and Fouts (1997) conducted a study on 243 firms using ROA as a measure of financial performance. The results revealed that although correlations were generally low, the correlation for the relationship between frim growth rate and ROA, and the industry growth were strong and positive. The results indicated that "it pays to be green" and that this relationship strengthens with industry growth. Ong et al (2014) carried out a research on 78 Malaysian companies to evaluate the impact of environmental improvements on financial performance. Ong et al (2014) hypothesized that there is a significant relationship between environmental performance (impact) and ROA. The results reflect a positive relationship for ROA. The results of the study suggest that it does indeed benefit a company to be green. This research is consistent with the research of Russo and Fouts (1997), which stated that policies on materials reuse is positively related to profit development. 13 | Page
Amosun Olayemi .O 4632788 Ahuja and Hart (1996) conducted a research on a sample of S&P 500 firms in USA on the relationship between emission reduction and firm performance and used ROA as a measure of financial performance. The results revealed that it does pay to be green. Although the relationship between emission and ROA became highly significant as a result of an increase in emissions, however, as emissions dwindled ROA increased. This shows that emissions reduction in any time period enhances operating performance of any company. In a research carried out by Iwata and Okada (2011) on Japanese manufacturing firms explaining how environmental performance affects financial performance revealed that the responses of financial performance are different depending on each environmental issue, the results of which are attributed to varying stakeholder preferences. The findings revealed that greenhouse gas reduction increases most long-run financial performance (ROA, ROE etc.); however, it does not have a significant effect on ROS. Goll and Rasheed (2013 cited by Achim and Borlea, 2014) emphasize that the environmental and financial performance can be connected to each other only in a specific context in which managerial choices matter more in certain types of environments than in others. In their study, they have identified a variety of factors that influence the relation between environmental and financial performance reflected by ROA (return on assets) and ROS (Return on sales) and highlight the major role that the munificent environments have on the intensity of this correlation. They found a significant positive correlation between financial performance (measured by ROA and ROS) and CSR in highly munificent and not in low munificent environments. Nakamura (2011) conducted a study on 3,237 Japanese companies to investigate the effect of environmental investment on firm performance. The authors’ result revealed that environmental investment / performance increases a firms (financial) performance. The positive effect of environmental efforts on economic performance ROA is insignificant at first but becomes significant later. Moneva and Ortas (2010) analysed the environmental and financial performance of 230 European companies between 2004 and 2007. Under the stakeholder approach, the commitment to environmental performances is analysed and linked with the firms’ financial improvement. The results supported the idea that 14 | Page
Amosun Olayemi .O 4632788 enterprises which obtained higher rates of environmental performance show better financial performance levels in the future. They found a positive and significant correlation between the two indicators only on the mid / long-term. Thus, firms that included corporate environmental performance issues in their strategic management policies would obtain a competitive advantage in the mid/long-term, significantly increasing their financial performance reflected by ROA, Profit margin, Cash flow, Operating profit. In support of explaining the negative correlation found between environmental performance and the company’s profitability, any invocation of high costs of CSR reporting, in addition to actual costs of investment in CSR, costs that lead to a lower operational efficiency of the organization during the investment period, is not negligible. As various researchers have found a positive relationship between environmental performance and financial performance (ROA), the following hypothesis is proposed: H1a: An increase in a company’s environmental performance will necessitate an increase in financial performance proxy by ROA.
2.5.2 Tobin’s Q as a dependent variable. Various researchers have used Tobin-Q ratio as a market-based measure of financial performance (Dowell et al., (2000); King and Lenox 2001; Konar and Cohen 2001; Jayachandran et al., 2013; Achim and Borlea 2014; Muhammad et al., 2015). However, some have found a positive correlation while some have found a negative correlation. King and Lenox (2001 cited by Brouwers et al., 2014) differentiated between pollution performance and divestiture of operations in dirtier industries by splitting environmental performance into two constructs: relative performance within one’s industries and the average performance of the industries in which one chooses to operate. For an unbalanced sample of 652 firms constituting 4483 firm-year observations for the years 1987 to 1996, they find an evidence of a positive association between pollution reduction and financial gains, as peroxided by Tobin’s Q.

Amosun Olayemi .O 4632788 Konar and Cohen (2001 cited by Brouwers et al., 2014) related the market value of 321 S&P 500 firms to environmental performance, as proxied by TRI emissions and environmental lawsuits. After controlling for variables traditionally thought to explain firm-level financial performance, they find that poor environmental performance is associated with lower Tobin's Q values. This shows that there is a relationship between EP and TBQ. Jayachandran et al. (2013) carried out a research on S&P 500 firms and Donuni 400 index firms on Corporate Social Performance (CSP) - firm performance. In analysing and explain the relationship the author used Product Social Performance (PSP) and Environmental Social Performance (ESP) to represent CSP. The results revealed that PSP had a significant positive effect on Tobin-Q while ESP does not have a significant impact on Tobin-Q. Muhammad et al. (2015) investigated the nature of the relationship between environmental performance and financial performance of publicly listed companies in Australia. The authors investigated the relationship of CEP using Tobin-Q (TBQ), the results revealed that CEP had a positive impact on TBQ during the pre-crisis period (2001-2007) and had no significant impact on TBQ during the crisis period (2008-2010). Wagner (2010) analysed the link between sustainability management and economic performance using a set of firms in Standard & Poor's 500 index. The study revealed that the effect of CSP on TBQ is high. Dowell et al. (2000) used a sample of firms drawn from the U.S. Standard and Poor’s 500 list of corporations. The authors concluded that there is a reliable positive and significant relationship between the use of a single global environmental standard and a firm’s Tobin’s q; there is a significant and positive relationship between the market value of a company (as measured by Tobin’s q) and the level of environmental standard it uses. This study points to the fact that there is a relationship between environmental performance and economic (financial) performance using TBQ. Achim and Borlea (2014) in their study observed that there is a positive correlation for the market performance represented by TBQ and EP. Their study illustrates that environmental investments are not immediately reflected in a growth in the companies’ financial accounting (or domestic) performance but rather in a 16 | Page
Amosun Olayemi .O 4632788 performance’s decrease based on the increase of environmental investment costs that leads to a decrease of assets’ efficiency for the analysed period. As various researchers have found a positive relationship between environmental performance and financial performance (Tobin-Q), the following hypothesis is proposed: H1b: An increase in a company’s environmental performance will necessitate an increase in financial performance proxy by TBQ.
2.5.3 Return on Capital Employed as a dependent variable Few researchers have used ROCE as an accounting-based measure of financial performance (Edwards 1998; Vinayagamoorthi et al., 2015). However, some have found a positive correlation while some have found a negative correlation. Vinayagamoorthi et al., (2015) carried out a research on Indian firms and the results revealed that the profitability variables like ROA, ROE, and ROS create the positive impact on energy intensity (proxy of environmental performance) of the sample firms. At the same time, one profitability variable such as ROCE recorded negative impact on EI. The results overall concluded that profitability variables of the firm (ROA, ROE, ROCE, and ROS) registered significant impact on environmental performance. Also, Wagner (2005) carried out a research on the European paper industry and the results indicated that the linear term of the environmental performance index has a positive, but insignificant effect on ROS whilst the squared term of the index has a significant and negative effect, which is also relevant in economic terms. ROCE had a negative effect on environmental performance. The results revealed an inversely U-shaped relationship between environmental and economic performance. Edwards (2015) researched on the link between company’s environmental performance and financial performance using ROCE as a measure of financial performance. The result revealed that there is a positive link between EP and ROCE. The following hypothesis is being proposed: H1c: An increase in a company’s environmental performance will lead to an increase in financial performance proxy by ROCE. 17 | Page

2.6 Control Variables. Various authors have used various variables such as company size, corporate governance, debt to equity, risk, current ratio, sales, growth, R&D, debt dependence and many more to explain financial performance. However, for this research work, the following variables have been chosen:
Company Size López-Gamero et al. (2009) in their research used size as a control variable. The results showed that size only had a significant influence on the early investment time and intensity in environmental issues, size is not considered a determinant for the degree of proactivity in the development of environmental management. Arago´n-Correa et al. (2008) also indicate in their study that size is a relevant but not a determining condition for developing the most proactive environmental management. Also, Russo and Fouts (1997) used firm size as a control variable for profitability. It was observed that firm size variable is significant and positive and size is a significant predictor of profitability. Waddock and Graves (1997) carried out a research on the corporate social performance – financial performance link and used size as a control measure of ROA. It was revealed there is a significant relationship between ROA and CSP when size is measured by sales, when size is measured by total assets; and when size is measured by number of employees. Therefore, it is expected that company size will have a positive influence on financial performance. It is hypothesized that: H2: There is a significant relationship between company size and financial performance.
Corporate Governance Achim and Borlea (2014) revealed that various studies have identified a strong correlation between the adoption of good corporate governance practices and companies’ performances. The authors argued that there is a positive relation between good corporate practices and financial performances. The coefficient for corporate governance (CG) indicated a weak but still positive correlation for 18 | Page
Amosun Olayemi .O 4632788 Romanian companies. In other words, the companies with good values for return on shareholders’ equity ratio, debt ratio, financial flexibility ratio, with strong corporate governance are expected to generate an increase in profitability’s companies (expressed by ROA). Furthermore, Bauer et al., (2007) examined the impact of corporate governance on firm valuation as measured by Tobin’s q and analysed the effect of corporate governance on firm performance. Gompers et al., 2003 (cited by Bauer et al 2007) in their research revealed that superior governance standards positively impact firm performance as measured by Net-Profit-Margin and Return-on-Equity in the U.S. the results showed that good-governance firms outperform poor-governance firms. However, various researchers have arrived at various results, it is expected that corporate governance will have a positive relationship with financial performance. Therefore, it is hypothesized that: H3: There is a significant relationship between corporate governance and financial performance.
Debt to Equity Jayachandran (2014) used financial leverage (debt to equity) measured as the ratio of long-term debt to total assets. This is expected to have a negative effect on Tobin’s Q. The results revealed that financial leverage and firm size are negatively related to Tobin’s Q. Achim and Borlea (2014) observed that debt to equity (leverage) was statistically significant to TBQ and ROA. Abuja and Hart (1996) observed that leverage was only significant in relation to ROE, and was a positive factor in one the observed years (1989) which became a negative factor in a later year (1990) as a result of recession. This observation reveals that leverage has a negative effect on ROA. For this research work, it is expected that Debt to equity will have a negative impact on financial performance. It is hypothesized that: H4: A decrease in Debt to equity will lead to an increase in financial performance.

Current Ratio Muhammad et al. (2015) investigated the nature of the relationship between environmental performance and financial performance of publicly listed companies in Australia. The authors observed that current ratio had a positive impact on ROA during the pre-crisis period and had no statistical significant impact on ROA during the crisis period. However, there results also showed that current ratio had a positive impact on TBQ during the pre-crisis period. Therefore, it is expected that current ratio will have a positive influence on financial performance. It is hypothesized that: H5: There is a significant relationship between current ratio and financial performance.
2.7 Conclusion In conclusion, although the results from the literature review communicate an inconclusive result in the study of the relationship between environmental performance and financial performance as a result of differences in environmental performance measures and financial performance measures, sample size, countries and industries. This research work will contribute more to existing literatures on the relationship between environmental performance and financial performance of FTSE 250 listed companies in the UK. The research work will use one of the least used financial performance measure ROCE as one of the financial performance measure. The study will be looking to answer the question most researchers ask on how environmental performance affects financial performance of companies. Does better environmental performance improve a firm’s financial performance?

CHAPTER THREE RESEARCH METHODOLOGY 3.1 Introduction The main aim of this study is for the researcher to investigate the research questions and to investigate theories supporting the hypothesis mentioned in the literature review chapter. It is necessary that the methodological scientific procedures be followed in order to validate the entire preconceived hypotheses. In this chapter, the methodology, research design, research questions, hypotheses, sources of data, ordinary least square, sample size, sample description, data collection instruments, limitation of the methodology, procedures for processing the data collected are all discussed.
3.2 Research Purpose The main aim of this study is to investigate the relationship between environmental performance and financial performance of companies in the UK, there is a need for a clear, specific and measurable descriptive analysis with thorough explanation. This study therefore adapts a descripto-explanatory research will analyse the descriptive data in order to draw conclusions which will help explain the relationship between environmental performance and financial performance (Zikmund, 2003). Descriptive studies are studies that aim to portray an accurate profile of persons, events or situations. This research intends to give a clearer picture on the phenomena on the data collected. Explanatory studies on the other hand are studies that establish causal relationships between variables. This study will also examine the set hypotheses in order to explain the relationship between variables. Combining both descriptive and explanatory studies result in a descripto-explanatory where, usually, description is the precursor to explanation (Saunders et al., 2012).
3.3 Research Design Research Design is a plan or blueprint which specifies how data relating to a given problem should be collected and analysed. It is a strategy a researcher employs 21 | Page
Amosun Olayemi .O 4632788 in investigating the relationship that exist among variables of the study so as to enable him/her collect data which will be used for the study (Adebayo, 2006). Research Design means the structuring of investigation aimed at identifying variables and their relationships to one another. It is an outline that serves as a useful guide to the researcher in his efforts to generate data for his/her study (Adebayo, 2006).
3.3.1 Data Source and Collection For this research work, the main source of data used is the secondary data. Secondary Data are primary data and other data collected earlier by other researchers and made available for reuse (Hox and Boeije, 2005). Secondary data comprises of textbooks, journals, e-book and databases. All financial data used was collected form the Financial Accounting Made Easy [FAME] database (2016) and all Environmental, Social and Governance data was collected from Thompson Reuters DataStream (2016). This study is cross sectional and the data was thus collected over a time period of 2 years.
3.3.2 Data Description 3.3.2.1 Dependent Variables Researchers and Scholars have all disagreed on the best measurement for measuring financial performance, accounting-based measures or the market-based measures(Achim and Borlea 2014). Previous researchers utilized accounting-based measures (Russo and Fouts 1997) and market-based measures (King and Lenox 2001). The accounting-based measure reflects companies’ internal efficiency and it meets the informational needs of managers, while the market-based measure meets the informational needs of the investors as the market value better reflects shareholders wealth than the accounting value (Achim and Borlea 2014). Both measures will be used in this research. The variables used were ROA, ROCE and TBQ. Return on Asset [ROA] and Return on Capital Employed were used as the accounting-based measure, while Tobin-Q was used as the market-based measure. ROA is the ratio of net profit after taxes to total assets. ROA reflects the current profitability of companies (Jayachandran et al., 2013). ROA indicates the efficient use of the firm’s total assets and also an indicator of the amount of profit a 22 | Page
Amosun Olayemi .O 4632788 firm generates for each unit of investment in assets (Palepu et al., 2010). There have been mixed results using this proxy in a number of studies as some researchers found a positive correlation and some found a negative correlation (Ahuja and Hart 1996; Russo and Fouts 1997).
Net profit (after taxes) *100
Return on Total Asset (ROA) =
Total Asset
TBQ (Tobin’s Q) ratio was used as the market-based measure. Tobin’s q is the firm market valuation over replacement value of assets (Dowell et al. 2000). It measures the market valuation of a firm relative to the replacement costs of tangible assets (Lindenberg and Ross 1981). This variable, is used to gauge how the market assesses the current ongoing value of the firm’s assets. A Tobin’s Q value greater than one indicates that investors assess the current value of assets as being higher than the replacement costs of the same assets (Lee and Tompkins 1999). Tobin Q (TBQ) =
Total Market Value of Firm Total Asset Value of Firm
ROCE was used as an accounting-based measure. This is included as a measure of the efficiency of the capital employed in producing income (Edwards 2015). This ratio measures how much a company has earned on invested long-term funds. It measures a company’s profitability and the efficiency in which capital is employed (Aerts and Walton, 2015). ROCE =
Profit before interest and tax *100 Capital employed (Total Asset - Current Liabilities)

3.3.2.2 Independent Variables Explanatory variable The explanatory variable used was environmental performance. An environmental score card from Thomson Reuters ASSET4 was used as a proxy for environmental performance. This has been used in a number of literature (Russo and Fouts 1997; Nakao et al. 2007). Environmental Performance score measures a company’s impact on living and non-living natural systems, including the air, land and water, as well as complete ecosystems. It reflects how well a company uses best management practices to avoid environmental risks and capitalise on environmental opportunities in order to generate long-term shareholder value. The environmental performance score covers emission reduction, resource reduction and product innovation (Thomson Reuters 2016). Emission reduction comprises of: emissions reduction policy, CO2 equivalents emission total, CO2 equivalents emission direct, CO2 equivalents emission indirect, CO2 equivalent indirect emissions, scope three, commercial risks and/or opportunities due to climate change, CO2 reduction, ozone-depleting substances reduction, NOx and SOx emissions reduction, NOx emissions, SOx emissions, VOC emissions reduction, VOC emissions, waste total, non-hazardous waste, hazardous waste, waste recycling ratio, water pollutant emissions, waste recycling ratio, water pollutant emissions, waste reduction initiatives, environmental management systems certified percent, sustainable transportation and environmental expenditures. While resource reduction includes: energy efficiency policy, toxic chemicals or substance reduction, energy use total, direct energy purchased, direct energy produced, coal energy purchased, coal energy produced, natural gas energy purchased, natural gas energy produced, oil energy purchased, oil energy produced, electricity purchased, electricity produced, renewable energy use, green buildings, water efficiency policy, water use total, water recycled and environmental supply chain management. Product innovation covers:
energy footprint reduction,
environmental R&D expenditures, renewable/clean energy products, water technologies and product innovation/product impact minimization (Thomson Reuters 2016). 24 | Page

Control variables The control variables used in this research are company size, corporate governance, debt to equity and current ratio (King and Lenox 2001; Nakao et al. 2007). These control variables were selected as a result of the significant influences they have on environmental performance. Studies by (Russo and Fouts 1997; Iwata, H. and Okada, K. 2011; Hatakeda et al. 2012; Muhammad et al. 2015) have confirmed that each control variable chosen have a significant relationship with financial performance of companies. Corporate Governance score measures a company’s systems and process, which ensures that its board members and executives act in the best interests of its long-term shareholders. It reflects a company’s capacity, through its use of best management practices, to direct and control its rights and responsibilities through the creation of incentives, as well as checks and balances in order to generate long-term shareholder value. The corporate governance score covers board structure, board function, compensation policy, shareholder rights and vision & strategy (Thompson Reuters 2016). Company Size is measured as the logarithm of the firm asset as suggested by Wanger (2010); Russo and Fouts (1997); Iwata, H. and Okada, K. (2011). Research has shown that company size has an impact on a firm’s environmental performance and the response of firms in terms of improving their environmental issues (Iwata, H. and Okada, K., 2011; Hatakeda et al., 2012). Company Sze =
log 𝑇𝑜𝑡𝑎𝑙 𝐴𝑠𝑠𝑒𝑡
Debt to Equity is measured as the ratio of total liabilities to stockholders’ equity. Research using debt to equity evince that debt to equity influences a firm’s financial performance (Iwata and Okada 2011; Muhammad et al. 2015). Debt to Equity (D2E) =
Total Liabilities *100 Stockholders’ Equity
Current Ratio is calculated as current assets over current liabilities is used to measure the liquidity of a firm and is expected to influence a firm’s financial performance (Muhammad et al. 2015; Iwata and Okada 2011). 25 | Page

3.4 Sample Size The research sample used consist of 111 companies listed on the FTSE 250 index on the London Stock Exchange in order to ensure comparable results, companies with data missing from FAME and DataStream were excluded from the sample as well as all companies from the financials industry (Chithambo and Tauringana 2014). This is as a result of the difference in the disclosure requirements for financials. The years of comparative study were 2013 and 2014.
3.5 Research Method A quantitative method was applied to this research work as numerical data and statistical analysis were applied to examine the relationship between environmental performance and financial performance (Saunders et al. 2012).
3.5.1 Ordinary least square modelling The relationship between environmental performance and financial performance was analysed using Ordinary Least Square method [OLS] regression as used by (Hayes and Cai 2007; Field 2013). The OLS model is as stated follows: Model 1: Multiple linear regression 𝑌 = 𝛽0 + 𝛽1 𝑋1 + ⋯ + 𝛽𝑘 𝑋𝑘 + 𝜀 Where Y is the dependent variable, 𝛽0 is the constant that is the intercept with Yaxis, X1,…,k, is the independent variable and β1…k, is the predicted value of the independent variables. ε is the error term of the model which represents all other factors affecting Y other than X1,…,k,. This means that the β provides information about the relationship between the independent and dependent variables (Hill).
3.5.2 Econometric modelling The above model can be replicated as follows in order to incorporate the variables of interest in this research: 26 | Page

Amosun Olayemi .O 4632788 2014 was 10.06% and 10.31%, this suggests that the managers of the companies sampled utilised the assets in an effective and efficient manner (Muhammad et al., 2015). The standard deviation was 25.04% and 28.38% in 2013 and 2014 which shows that the values of the data set were widely spread around the mean. The mean, maximum, minimum and standard deviation values of this research indicates that the number of observation is of a larger scale than the previous research of Achim and Borlea, (2014); Ong et al., (2014) and Muhammad et al., (2015). In 2013 and 2014 the minimum ROCE was -324.14% and -236.95% while the maximum ROCE was141.41% and 404.14% respectively. The mean for ROCE in 2013 and 2014 was 10.91% and 14.38% which suggests that managers of the sampled companies proficiently used the equity and debt to generate more returns for the companies. Standard deviation for 2013 and 2014 was 37.36% and 49.36% correspondingly, which is higher than the standard deviation value for the research work of Ruchika, (2013) and Vinayagamoorthi et al., (2015). Although the mean, minimum, maximum and standard deviation values were higher than previous research works, the total number of observation was lower than the previous investigations. The minimum TBQ values for 2013 and 2014 was 0.00 and 0.087 while the maximum TBQ values were 132.77 and 225.09 in 2013 and 2014 correspondingly. TBQ shows a standard deviation value of 15.49 and 22.80 which shows a very good and large spread in the observation and a mean value of 3.98 and 4.85 in 2013 and 2014. In applying the needed interpretation, the mean of TBQ established in this study suggests that on average the FTSE 250 UK firms have a high market value. The mean from this observation is similar to the results from Dowell et al., (2013); King and Lenox, (2001); Konar and Cohen, (2001); Jayachandran et al., (2013) and Muhammad et al., (2015). As it can be seen in the table above, the explanatory variable EP in 2013 and 2014 had a minimum value of 11% and a maximum value of 94% in 2013 and 2014 respectively. EP shows a standard deviation of 24.46% (2013) and 24.38% (2014) which reveals that the observations were broadly spread round the mean. While the mean was 60.41% and 62.17% respectively which suggests that companies are involved in environmental matters that affect the companies and the community. 29 | Page
Amosun Olayemi .O 4632788 With regards to CG as a control variable, the minimum values were 33% and 25%, while the maximum values were 95% and 96% in 2013 and 2014 correspondingly. CG shows a standard deviation of 14.22% and 12.41% which shows a high spread of the observation, while the mean value was 76.20% and 81.50%. In interpreting, the mean suggests that companies used in the study are highly involved in having a good corporate governance system. Control variables CR and SIZE had the lowest minimum values of 0.00 in 2013 and 0.00, 0.76 in 2014, and the lowest maximum values for CR 5.80, 5.57and SIZE 4.03, 3.87 in 2013 and 2014 respectively. CR and Size also had the lowest standard deviation values of 1.06; 0.62 in 2013 and 0.98; 0.48 in 2014 which reveals that the observations had a very low and uneven spread. The mean for CR 1.60 and 1.55 and the mean for SIZE 2.97 and 3.03 in 2013 and 2014 correspondingly. The minimum values for D2E were -30.08 and -34.70, while the maximum values were 111.55 and 38.23 in 2013 and 2014 respectively. The standard deviation values were 11.95 and 7.02 which shows that the observation was largely set round the mean in 2013 and 2014. The mean values were -1.11 and -1.18 in 2013 and 2014. From the table above, it can be observed that the variables increased in 2014 in comparison to 2013 which shows more companies increased their assets, capital employed, liabilities, size and market value.

From the above table, it can be denoted that the correlation between CG and EP is a weak but positive relationship and significant. The relationship between SIZE, ROA and TBQ is weak and negative but is significant. However, the correlation between EP and ROA -0.154 suggests a weak and negative the relationship between EP and ROA which does not support hypothesis H1a. The correlation is not significant.

EP
Source: Authors output from the regression through E-Views (2016) Figure 4.1 shows that although companies with high ROA have high EP, most of the observation reveals that an increase in EP does not mean an increase in ROA. This can be as a result of the use of various industries in this study, as each industry has various rules and requirements for EP as well as a result of an increase or decrease in the assets of companies. The correlation matrix shows that there is no relationship, the trend line is negative in 2013. Therefore, the null hypothesis applies to this variable which states that an increase in a company’s environmental performance will not necessitate an increase in financial performance proxy by ROA. The correlation matrix reveals that there is a weak but positive relationship between EP and TBQ with a coefficient of 0.075, which is in agreement with hypothesis H1b. the relationship is shown in the scatter plot and interpreted below.

Source: Authors output from the regression through E-Views (2016) In Figure 4.2 shows that an increase in the observations EP lead to a slight increase in TBQ which shows that an increase in EP may lead to an increase in the market capitalisation and asset of a company. This means the companies were not undervalued or overvalued. However, the correlation is not significant. The correlation between EP and ROCE suggests a negative relationship with a negative co efficient of 0.101, this relationship does not conform to the expectations from hypothesis H1c. The correlation is not significant and the relationship is shown in figure 4.3 below.

EP
The above figure divulges that an increase in EP does not lead to an increase ROCE which can be attributable to a decline in profitability and the efficiency in which companies generated cash. This means companies did not efficiently use their resources to generate more profit which can be interpreted as a decline in the rate of return earned by the companies. SIZE is the only control variable that is significantly correlated with ROA and TBQ. All control variables had negative relationships with the dependent variables excluding CG which had a positive relationship with TBQ and D2E which had a positive relationship with ROA. The highest correlation coefficient recorded in Table 4.2 A is 0.125.

Note: ** and * indicates the significance level at 1% and 5%. Source: Authors output through SPSS 22 using Fame and Asset4 ESG data (2016). Table 4.2 B reports the correlation coefficients between the dependent and independent variables for 2014. The correlation coefficient of EP and ROA is -0.087, this negative linear relationship suggests that there is no relationship between EP and ROA which does not support hypothesis H1a. There is a positive correlation relationship between EP and CG which can be interpreted as an increase in corporate governance standards will lead to an increase in environmental performance of companies. The correlation is significant at 1%. The relationship between ROA and EP is shown in Figure 4.4 (see appendix A3). In comparison with 2013, the scatterplot shows a greater decline in ROA. This can be further interpreted as an increase in EP leads to a decline in ROA. It can be propounded that as companies improve on emission reduction, resource reduction and product innovation, return on asset declines as most of the companies may be less asset heavy which can be as a result in variations in the industries used in the sample. The correlation coefficient between EP and TBQ is 0.119, this represents a weak but positive relationship which corresponds with hypothesis H1b. In comparison with 2013, the correlation coefficient increased by 0.044 which can be deduced as a yearly increase in TBQ will lead to a yearly increase in EP. The scatterplot for this relationship is shown in figure 4.5 (see appendix A3).

Amosun Olayemi .O 4632788 Figure 4.5 reveals that an increase in EP lead to the increase in market capitalisation and asset of few companies. Although an improvement in EP lead to a slight increase in the market value of the companies sampled when compared to 2013, the increase was low. It is therefore proposed that as companies improve further on their environmental impacts, the market value of the companies will increase. The correlation relationship between EP and ROCE is weak, negative and insignificant. The coefficient is -0.031. This suggests that there is no relationship between EP and ROCE which does not support hypothesis H1c. The relationship is shown in figure 4.6 (see appendix A3). From Figure 4.6, it can be seen that companies with a high ROCE also have high EP scores. Most of the companies have high EP and ROCE between 0 and 100. However, from the correlation the trend line explaining the relationship is negative as the scatterplot reveals that a high number of the companies from the observation with negative ROCE have high EP which will have impacted the coefficient. It can be propounded that a decrease in a company’s emission production, resource reduction and an increase in product innovation does not necessarily lead to an increase in the company’s ROCE. SIZE also is the only control variable that is significantly correlated with all the dependent variable and independent variable (EP). All control variables had negative relationships with the dependent variables excluding CG which had a positive relationship with TBQ, CR which had a positive relationship with ROA and D2E had a weak, positive and significant relationship with ROCE. The correlation coefficient relationship is in correspondence to hypothesis H2 and H4. The highest correlation coefficient recorded in Table 4.2 B is 0.166. According to Gujarati and Porter (2009), multicollinearity will occur if the correlation coefficient among variables exceeds the rule of thumb level i.e. in excess of 0.8. The observation was tested for multicollinearity. The highest correlation recorded among the independent variables in 2013 was 0.109 and 0.408 in 2014. The correlation coefficient between the independent variables for both years did not exceed the rule of thumb. There were no obvious concerns and irregularities in the data. In additional analysis, a Variance Inflation Factors (VIFs) test was carried out 36 | Page
Amosun Olayemi .O 4632788 to diagnose multicollinearity among the variables used in this study. The results show that the highest VIF value in 2013 is 1.264 and the lowest is 1.005, while the highest VIF value in 2014 is 1.244 and the lowest is 1.004 suggesting that multicollinearity is not an issue as O’Brien (2007) states that the VIFs should be less than 10 (rule of thumb) in order to avoid multicollinearity. Auto correlation was not tested for as this research work is across sectional regression and not a panel regression.

4.2.3.1 Model 1: ROA Table 4.3 shows the results of the test carried out using ROA as a dependent variable for 2013 and 2014. The results for 2013 are recorded in column 2 and for 2014 in column 4. Model 1 is estimated using EP and the financial control variables. The result indicates that EP has a negative impact on ROA in 2013 (β=-0.117, tstatistics = -1.107) and 2014 (β=-0.006, t-statistics = -0.05). The R square and Adjusted R square for this model is 0.103 and 0.061 in 2013 is very low and the R square and Adjusted R square for 2014 is 0.162 and 0.123 is low which suggests that the model explains none of the variability of the response data around the mean. Therefore, it is expected that other countless factors affecting ROA were not included in the model. The results confirm that an increase in environmental performance leads to a decrease in return on assets. The model predicts an increase in EP leads to a decline in ROA by 0.117 and 0.006 in 2013 and 2014 respectively. The result is not significant and does not confirm hypothesis H1a: An increase in a company’s environmental performance will necessitate an increase in financial performance proxy by ROA. Therefore, the hypothesis is rejected. In 2013 and 2014 Size had a negative but significant relationship with ROA which supports hypothesis H2: There is a significant relationship between company size and financial performance. CG and CR had a negative and insignificant relationship with ROA which does not support hypothesis H3: There is a significant relationship between corporate governance and financial performance and H5: There is a significant relationship between current ratio and financial performance. Thus, both hypotheses are rejected. D2E had a weak but positive relationship with ROA in 2013 which supports hypothesis H4: A decrease in debt to equity will lead to an increase in financial performance. The hypothesis is accepted. However, D2E had a weak and negative relationship with ROA in 2014 which does not support hypothesis H4, thus, the hypothesis is rejected and the null hypothesis is accepted.
4.2.3.2 Model 2: TBQ Table 4.3 reports TBQ results for both periods 2013 and 2014. Model 2 is estimated using EP and financial control variables. The result indicates that in 2013 EP has a positive impact on TBQ (β=0.062, t-statistics = -1.025) and in 2014 (β=39 | Page
Amosun Olayemi .O 4632788 0.212, t-statistics = 2.837). The R square and Adjusted R square for this model is 0.236 and 0.2 in 2013 is low and the R square and Adjusted R square for 2014 is 0.454 and 0.428 is low which suggests that the model explains none of the variability of the response data around the mean. Therefore, it is expected that other factors affecting TBQ were not included in the model. The results show that EP has a positive relationship TBQ in 2013. However, the relationship is not significant, which implies that although an increase in EP necessitated an increase in financial performance proxy by TBQ, hypothesis H1c will be rejected. In 2014 EP had a significant and positive relationship with TBQ. This model suggests that an increase in environmental performance will lead to a 0.212 increase in TBQ which supports hypothesis H1c: An increase in a company’s environmental performance will lead to an increase in financial performance proxy by TBQ. Size in 2013 and 2014 had a negative and significant relationship with TBQ which supports hypothesis H2: There is a significant relationship between company size and financial performance. D2E and CR for both years had a negative and insignificant relationship with TBQ which does not support hypothesis H4: A decrease in debt will lead to an increase in financial performance and hypothesis H5: There is a significant relationship between current ratio and financial performance. CG has a weak and positive relationship for both years, however, the relationship was not significant and is not in line with hypothesis H3: There is a significant relationship between corporate governance and financial performance. The hypotheses for D2E, CR and CG is therefore rejected.
4.2.3.3 Model 3: ROCE Table 4.3 reports ROCE results for both periods 2013 and 2014. Model 3 is estimated using EP and financial control variables. The result indicates that in 2013 EP has a negative impact on ROCE (β= -0.036, t-statistics = -0.218) and in 2014 has a positive impact on ROCE (β=0.171, t-statistics = -0.835). The R square and Adjusted R square for this model is 0.042 and -0.004 in 2013 is low and the R square and Adjusted R square for 2014 is 0.13 and 0.089 is low which suggests that the model explains none of the variability of the response data around the mean.
40 | Page
Amosun Olayemi .O 4632788 Therefore, it is expected that other factors affecting ROCE were not included in the model. The regression results in 2013 show that EP has a weak and negative relationship with ROCE and in 2014 has a weak and positive relationship with ROCE. The relationship is insignificant and does not conform to hypothesis H1c: An increase in a company’s environmental performance will lead to an increase in financial performance proxy by ROCE. Since the relationship is insignificant relationship, hypothesis H1c is rejected and hypothesis H0 is accepted. The relationship between CG, CR and ROCE in 2013 and 2014 is negative and insignificant, which is not in correlation with hypothesis H3: There is a significant relationship between corporate governance and financial performance and H5: There is a significant relationship between current ratio and financial performance. Size in 2013 has a negative relationship with ROCE which does not support hypothesis H2, while in 2014 has a negative but significant relationship with ROCCE which is in correspondence with hypothesis H2: There is a significant relationship between company size and financial performance. Furthermore, the relationship between D2E and ROCE in 2013 was negative and insignificant and does not correlate with hypothesis H4, while in 2014 the relationship is positive and significant and is in line with hypothesis H4: A decrease in debt to equity will lead to an increase in financial performance.
4.3 Discussion of Findings This study has attempted to address what has become an important question Does better environmental performance improve a firm’s financial performance? In undertaking the research, this study is exploring whether or not any significant link exists between EP and FP measures using data from the FTSE 250 UK market. Several researchers have noted that it is best not to make a general conclusion that EP and FP have no relationship or have a negative relationship (Cordeiro and Sarkis, 1997; Gilley, K., 2000). Various studies (Mahapatra, 1984; Aupperle et al., 1985; Jaggi and Freedman, 1992; Russo and Fouts, 1997; McWilliams and Siegel, 2000; Konar and Cohen, 2001; Takeda and Tomozawa, 2004; Takeda and Tomozawa, 2004; Yamaguchi, 2008; Jacobs et al., 2010; Jayachandran et al. 2013; Primc and Cater 2015) have identified the relevance of environmental information to investors. 41 | Page
Amosun Olayemi .O 4632788 Thus, any positive or negative environmental performance information will have an immediate impact on a company’s market value and financial performance. The results of a negative and insignificant relationship between environmental performance and financial performance (ROA) are consistent with prior studies (Connelly and Limpaphayom, 2004; Achim and Borlea, 2014). The negative effect on ROA can be explained by the fact that good environmental performance of a company does not necessarily increase the financial performance of a company, but has a significant or insignificant effect on it. However, it was observed that the impact of environmental performance on ROA was better off in 2014 compared to 2013, which means as a company improves on environmental performance there is a likelihood that there will be an increase in ROA. A company’s improvement on environmental matters such as environmental R&D expenditures, reduction in ozone-depleting substances, waste recycling, renewable energy products, product innovation impact minimization and so on may lead to an increase in cost which will lead to a decrease in income which will lead to a decrease in the total asset of companies. It is often argued that social and political pressures are what motivates or obligates companies to be clean and green corporate citizens. The results of a positive and insignificant relationship between EP and TBQ in 2013 and a positive and significant relationship between EP and TBQ in 2014 are consistent with previous studies (Dowell et al., 2000; King and Lenox, 2001; Konar and Cohen, 2001; Wanger, 2010; Achim and Borlea, 2014; Muhammad et al., 2015). The positive relationship between environmental performance and TBQ as a marketbased measure of financial performance implies that companies that engage in corporate social responsibilities in order to achieve high environmental performance have a higher competitive advantage, as there will be an increase in market value which signifies an increase in market performance. A negative and insignificant relationship between EP and ROCE in 2013 is consistent with prior research (Wagner, 2005; Vinayagamoorthi et al., 2015). This can be interpreted as an improvement in the environmental performance (product innovation, environmental expenditures, footprint reduction, green buildings and water technology) of a company leads to a decrease in the income of a company which in turn leads to a decrease in ROCE. However, it was observed in 2014 that as 42 | Page
Amosun Olayemi .O 4632788 companies improved more on product innovation, energy efficiency, waste recycling, water use, sustainable transportation and much more, reduces costs and increases the return the company gets. The result is not significant and thus, does not conform to the previous study that found a positive relationship (Edwards, 2015). It was expected that company size will have a significant relationship with financial performance. It was observed that size had a negative and significant relationship with financial performance. This result is in line with (Waddock and Graves, 1997; Lopez-Gamero et al., 2009, Jayachandran et al., 2013), and contradicts the work of Russo and Fotus, (1997). Corporate governance was expected to have a significant relationship with financial performance. However, this study found out that corporate governance had a negative and insignificant relationship with ROA and ROCE, but had a positive and insignificant relationship with TBQ which does not support the findings of Bauer et al., (2007) and Achim and Borlea (2014). It was observed that current ratio had a negative and insignificant relationship with the three financial variables used. The findings are not in line with the previous studies of Muhammad et al., (2015) who found out that current ratio had a positive impact on ROA and TBQ during the pre-crisis period but had no statistical significant impact on ROA during the crisis period. Debt to equity was expected to have an impact on environmental performance. The findings showed that debt to equity has a significant impact on ROCE and ROA and not on TBQ. This is in line with the findings of Abuja and Hart, (1996) and Achim and Borlea, (2014) and contradicts the work of Jayachandran, (2014) and Muhammad et al., (2015).
4.4 Summary of Findings In summary, the empirics provided in this study shows that an increase in environmental performance by companies in the form of energy efficiency, emission reduction policy, reduction of commercial risks and/or opportunities due to climate change, reduction in waste, increase in recycling, increase in the use of renewable energy, production in renewable/clean energy products and product innovation will lead to an increase in TBQ. Although the impact on ROA and ROCE was not 43 | Page
Amosun Olayemi .O 4632788 significant, the results reveal that a yearly improvement in environmental performance will lead to an improvement in financial performance. It is therefore proved that an increase in environmental performance will have an impact on the financial performance and success of a company. This finding therefore supports the research works of Russo and Fouts, (1997), Konar and Cohen, (2001), Takeda and Tomozawa, (2004), Yamaguchi, (2008), Jacobs et al., (2010) and Muhammad et al., (2015). Furthermore, this study also supports the Stakeholder Theory, Win win view, Resourced-based view and the Economist’s view which supports that there is a relatioship between environmental performance and financial performance.

CHAPTER FIVE CONCLUSION AND RECOMMENDATIONS 5.1 Introduction This chapter presents the conclusions of the main results and gives limitations and recommendations for further studies.
5.2 Conclusion This study examines the relationship between environmental and financial performance using the data of FTSE 250 firms in the UK from 2013 and 2014. Environmental issues have been diverse in recent years and various stakeholders have various expectations and preferences for various environmental issues. In order to examine the relationship, this study employed three financial performance indices to further explain the relationship with environmental performance. A large number of studies have observed examined the relationship between environmental performance and financial performance, however, there have been no conclusive results about the relationship. Environmental performance plays an important role in financial performance which could be as a result of the economic benefits that can be derived from companies investing in environmental incentives, or can be as a result of the potential increase in profitability and market value of firms. In testing the hypotheses, the regression results revealed that only one of the financial performance measure had a positive and significant relationship with environmental performance. It was observed that in 2014, the correlation between environmental performance and ROA and ROCE increased. This suggests that companies endeavour to minimize the impact of their environmental issues. However, as the regression shows different results on the three financial measures used, it is advisable that general conclusions should not be made. Overall, the results provide support that environmental issues are important and firms need to have incentives to reduce their environmental damages as financial performance is positively related to environmental performance. This means that environmental problems may be solved by the market mechanism without 45 | Page
Amosun Olayemi .O 4632788 government intervention, leading to a preferable environment for both firms and the government. However, companies, governments and the society at large still need to invest more into ensuring that environmental matters are taken care of effectively.
5.3 Limitations It is expected that any research work will encounter limitations. Among the limitations of the research work, the sample size was relatively small as financial companies and companies without data were excluded. The study used a limited analysis period of 2 years (2013 and 2014) which prohibited an industry and sectorial analysis. The study was limited to FTSE 250 UK companies.
5.4 Recommendations In light of the findings of this research work, some recommendations have been made for future contributions to the investigation on the relationship between environmental performance and financial performance. In order to account for an increase in the correlation and significance in the relationship between environmental performance and financial performance, other financial variables such as Return on equity, net profit margin, gross profit margin, stock return volatility and return on sales can be included in future studies. Other control variables such as growth ratio, flexibility ratio, fixed asset, advertisement and capital intensity should be used. It is advisable that other environmental performance variables such as GHG emissions, waste, carbon emissions, emissions to air, biodiversity, resource efficiency and water should be used in further research works. Also, it is recommended that a panel regression should be used and a larger analysis period be used in investigating the relationship between environmental performance and financial performance. For future research, it is recommended that a larger sample size, sample study and geographical location be used as this will provide more insight to the relationship between environmental performance and financial performance. Lastly, recommended for further research is the relationship between environmental performance and financial performance on an industrial and sectorial level. The relationship between corporate governance and environmental performance. The relationship between corporate governance and financial 46 | Page
