Abstract
The quality of GHG-disclosure and GHG- intensity in relation to financial
performance regarding large listed companies -
Is GHG-disclosure value relevant for shareholders?
This study assesses the association between the quality of GHG- disclosure and financial performance. Literature about the legitimacy and stakeholder theory is being used to form
hypotheses. These theories are addressing that the success of a company depends on its ability to manage the relationship with stakeholders and gaining legitimacy. This study looks for an answer to the question if providing a higher quality of GHG-disclosure is value relevant for shareholders. The sample in this research consists of worldwide large listed companies because they receive increased attention from stakeholders and perform more environmentally affecting activities. By using corporate reports from these
companies, the quality of these disclosures is measured. GHG-
intensity is taken into account as a moderator. In addition, the effect of GHG-intensity on financial performance is also tested by using multiple regression analysis. I found evidence that a higher quality of GHG-disclosure can improve a firm its financial performance measured in terms of Tobin’s q and is therefore value relevant for shareholders. This relation is not affected by the GHG-intensity of a company. Also, a higher GHG-intensity does not influence the
financial performance of a company. However, this study is useful for companies, investors and other users of GHG-disclosure
because it shows the value of high quality disclosures.
Key words: environmental disclosure, voluntary disclosure, Greenhouse Gas,

1. Introduction
The emission of greenhouse gas is a huge problem and serious threat for the world.
Therefore, countries undertake action. For example, at the end of 2015, the Paris
agreement was signed. This is an agreement between countries all over the world to slow down and stop the global average rise in temperature. The emission of Greenhouse Gas (GHG) is often related to a global rise in temperature. A key point of the Paris agreement is to reduce these GHG-emissions. To monitor this reduction, the countries agreed on rules to report in a consistent way about their emissions and plans (NRC Handelsblad, 2016). Basically, the reporting is not the problem, the emission generated activities are.
For example, companies in the utilities and oil & gas industry are expelling a lot of GHG-emissions. Basically, every company has some sort of direct or indirect GHG- emissions. Therefore, companies are receiving more interest from stakeholders regarding environmental activities (Rankin, Windsor & Wahyuni, 2011). To serve this interest, companies have started to disclose information about their GHG-emission.
This GHG-disclosure is still voluntary.
As stated before, the effects of climate change are becoming more and more important.
Rokhmawati, Sathye and Sathye (2015) argue that climate regulation and the more environmentally consciousness of stakeholders makes GHG-emission a growing significant risk, not only for the world, but also for companies. This could lead to a negative financial performance if companies do not take sufficient measurements to deal with those risk and do not respond to the increased pressure of stakeholders (Kolk, Levy and Pinske, 2008). GHG-disclosure is important to identify these risks and to communicate it towards stakeholders (The Greenhouse Gas Protocol Revised Edition).
Also, Iatridis (2013) is arguing that high quality disclosures are a signal of transparency
and allows investors to make informed judgements and eventually reduces uncertainty
which could lead to a competitive advantage for the company. In addition to stronger
regulations, companies face also another challenge. During the years, governments
introduced systems with the objective to reduce GHG-emission. An example in the EU is
a so-called cap and trade system. This cap and trade system is a set limit for companies
that refers to the maximum amount of emission that is allowed for an industry for a
certain period to emit. Due the fact that companies are allowed to buy and sell these
allowances, a lot of trading in allowances exist, causing a costs of carbon’. To meet future targets of the Paris Agreement, the CDP made a visualisation (Appendix 1) of the
expected price of carbon which is needed to meet those targets. Carbon dioxide is a gas that belongs to the group of Greenhouse Gases but is the most emitted. CDP stands for
‘Carbon Disclosure Project’, this organisation is there for institutional investors to motivate companies to disclose information about GHG.
As mentioned before, all companies have a certain amount of GHG-emissions. This is referred to as GHG-intensity. Over the last years, companies receive more attention regarding this topic which causes an increase in the need for information from stakeholders. In the basis, large companies receive more attention in general from stakeholders, which improves the need for information even more (Peters and Romi, 2014). In addition, large companies are carrying out more activities that affect the
environment and therefore also receive more attention form stakeholders (Rankin et al., 2011). Research indicates that environmental disclosure increases when companies are bigger, and that companies with an active strategy of stakeholder management make more extensive environmental disclosures (Magness, 2006). Freeman (1994) argued that the success of an organization depends on its ability to manage relationships with these stakeholders. Managing these relationships makes a good business sense, since managers are able to achieve their objectives in economic terms. However, these efforts of
publishing disclosure and managing the relationship with stakeholders are a costly activity for companies. Therefore, the effects on financial performance is a well-studied object. Beurden & Gössling (2008) performed a literature review about the relationship between Corporate Social Responsibility (CSR) and financial performance.
Environmental related disclosure can be seen as part of CSR. 23 studies found a significant positive relationship between CSR and financial performance, six studies found no significant relationship and two studies found a significant negative
relationship. In conclusion, acting ‘responsible’ pays off for a company.
However, a ‘problem’ with CSR is that there is no overall accepted definition. Dahlsrud (2006) performed a research on the definition of CSR used in the academic literature.
He divided CSR into five different dimensions. These dimension are economic
dimension, stakeholder dimension, social dimension, environmental dimension and
voluntariness dimension. The environmental dimension and voluntariness dimension
were significantly lower represented than the other dimensions. This is an important
finding because GHG-disclosure can be seen as part of the environmental and
voluntariness dimension which are lower represented within the literature. The results of Beurden & Gössling (2008) indicate a positive effect on financial performance, however CSR is broader than the environmental aspect. GHG-disclosure is even a more specific topic within the environmental aspect. Therefore, it is not necessarily proven that GHG-disclosure pays off.
There is also research available with a focus on environmental level. For example, Ness
& Mirza (1991) found that the environmental disclosure intensity in the oil industry was significantly higher compared to non-oil companies, however they did not research the effect on the financial performance of these companies. Iatridis (2013) performed research on the quality of environmental disclosure and its relation to shareholders value. The result was that indeed, the quality of environmental disclosure is viewed as value-relevant for shareholders. In his research, an index score for measuring the
quality was used. This index score was designed based on reporting guidelines that were broader than reporting about GHG only. Therefore, it is not proven that GHG related disclosure has value-relevance. Research with specific focus on GHG is not
overwhelming (Rokhmawati et al., 2015). In addition, they argue that regular studies about the environment are not applicable for GHG related issues given the unique characteristics and content considering carbon management. This means that GHG must be handled as a separate study objective.
The research of Iatridis’ (2013) researched only companies in Malaysia. In this research, Malaysia was classified as an advanced emerging market during the study. The need for capital is higher in emerging markets and higher quality of environmental disclosure reduces the difficulties in accessing capital markets (Iatridis, 2013). Well established companies do not have the same need for capital as companies in an emerging market.
Therefore, you could ask the question if this value relevance is applicable for established companies on a global level. Rankin et al. (2011) found that the energy and mining and industrial sector discloses more credible information compared to industries which have a lower GHG-intensity. Therefore, it is worth to research and consider the moderation effect of GHG-intensity on the relationship between the quality of GHG-disclosure and financial performance. In addition, the effect of GHG-intensity itself on financial performance will also be tested. As earlier mentioned, large companies have a higher GHG-intensity. Mainly because GHG-emission is a growing significant risk for companies they receive more attention from stakeholders and also provide more environmental disclosure. Due this high GHG-intensity in combination with more attention from stakeholders it is interesting to take large listed worldwide companies as a sample. The sample in this research consists of 500 large listed worldwide companies.
This study examines the quality of GHG-disclosure and its effect on financial
performance. Financial performance is measured in terms of Tobin’s q and Return on assets (ROA). A scoring index based on GRI-guidelines about GHG-reporting is used as a proxy for the quality of GHG-disclosure. Information about GHG-disclosure is obtained from reports published by the companies itself. GHG-intensity is measured in terms of’
total CO
2and CO
2equivalents in tonnes’.
The main research question of this paper is stated as follow:
‘’How value-relevant is GHG-disclosure for shareholders and what is the moderation effect of GHG-intensity on this relationship?
The remainder of the paper is organized as follows, in 1.1. a small background about integrated reporting is given. Section 2 gives an overview of the literature and
formulates the hypotheses. Section 3 describes the methodology of the research. The
results are presented in section 4 and the conclusion is presented in section 5.
1.1. Background Integrated Reporting
In this fast-changing world, there are concerns that the information provided to the stakeholder, in the form of traditional reporting methods, are not sufficient informative (Cheng, Green, Conradie, Konishi and Romi, 2014). During the years, attempts to
improve information consisted of reporting non-financial information next to traditional financial information. To report this information, a few different
mechanisms are used, for example stand-alone sustainability report, corporate social responsibility (CSR) report and even within the annual report (Cheng et al., 2014).
The International Integrated Reporting Council (IRRC) motivates companies to use a process “whereby an organisations’ value creation over time would be reported in a concise report, called integrated report, which would communicate an organization its strategy, governance, performance and prospects, in the context of its external
environment, in order to show value creation over the short, medium and long term”
(Cheng et al., 2014, p. 3). The IRRC is working together with the Global Reporting Initiative (GRI) to shape the future of corporate reporting were sustainability reporting play a vital role. GRI is a pioneer of sustainability reporting and helps businesses and governments worldwide to understand and communicate their impact on sustainability issues (website GRI, 2018
1). Section 305 of the GRI Guidelines is about emissions. This section is also based on reporting and measuring requirement set by the Greenhouse Gas Protocol. The Greenhouse Gas Protocol Initiative is a multi-stakeholder partnership of businesses, non-governmental organizations (NGO’s) and others with their mission:
“to develop internationally accepted GHG accounting and reporting standards for business and to promote their broad adoption” (The Greenhouse Gas Protocol Revised Edition, p. 1).
There are also organizations initiated by institutional investors which are especially there to motivate companies to disclose (more) information about carbon related issues.
Kolk et al. (2008) recognized two prominent organisations. These organisations are the Carbon Disclosure Project (CDP) and the Investor Network on Climate Risk (INCR). The INCR is smaller compared to the CDP and is only US-based and launched in 2003.
Earlier in 2000 the CDP was launched. The CDP has more focus on the business
implications of climate change and is international orientated (Kolk et al., 2008). The
CDP is focussing on companies which are included in the FT500. The FT500 is yearly
composed by the Financial Times and is a yearly overview of the biggest 500 listed
companies worldwide. The CDP is a very successful project for institutionalizing carbon
reporting and during the years 77% of the companies included within the FT500 have
disclosed information through CDP. This high activity is not surprisingly because
research also concluded that the size of the company is positively related to the amount of disclosure (Beurden & Gössling, 2008) and the FT500 consists of the 500 largest worldwide companies.
The CDP also published a Carbon Disclosure Score of every company that disclosed the information. Kolk et al. (2008) concluded that in terms of response rate CDP is
successful, but the level of carbon disclosure that provides information which is particularly valuable for investors is questionable and differs among companies. This research will find out how valuable these disclosures can be.

2. Literature review and hypotheses development
This section describes theories that are useful for studying corporate disclosures . The legitimacy, stakeholder and agency theory will be shortly introduced.
2.1 Literature review
Two well-known central statements made by Freedman (1970) are saying that “the social responsibility of business is to increase profits” and “managers’ only responsibility is to increase shareholders’ wealth”. Due to these statements managers can be viewed as employees of the stockholders. So “their only responsibility is to conduct the business in accordance wither the owner’s desires to make as much money as possible conforming to the basic rules of society’’ (Beurden & Gössling 2008). But Freeman (1994) did not agree with these statements and argued that in order to keep business legitimacy, some social performance is needed, and furthermore, accountability of managers is not only towards shareholders but also towards stakeholders. The legitimacy theory is often used to study the relationship between voluntary social and environmental disclosure
(Rankin et al., 2011) and is the most dominant perspective (Mousa & Hassan, 2015).
Corporate disclosures are according to Owen (2008) a way to conform to societal expectations or can be seen as a way of maintaining or regaining legitimacy.
Summarized in a different view with the same meaning, the legitimacy theory is saying that “corporate social reporting is aimed at providing information that legitimises company’s behaviour by intending to influence stakeholders’ and eventually society’s”
(Hooghiemstra, 2000, p.57). Isomorphic forces also play a role in this theory because these forces can limit effectiveness, flexibility and innovativeness and eventually force companies in a certain direction to gain legitimacy, were the quest for legitimacy
sometimes outweigh economic reasoning (Brandau, Endenich, Trapp & Hoffjan, 2013).
Another theory closely related with the legitimacy theory is the socio-political theory.
Both, the legitimacy and socio-political theory support empirical evidence that corporate disclosures exist most of the time because of public pressure and increased media attention and the goal of the company is to gain a ‘license to operate’ (Qui, Shaukat & Tharyan, 2016).
These theories do not directly describe the relation between disclosure and financial performance, but it does explain the voluntary social and environmental disclosures
‘phenomenon’ (Mousa & Hassan, 2015). So basically, they answer the question why
companies voluntarily disclose information about environmental and social aspects and
describe what their motivations are. Hooghiemstra (2000) argued that communication is closely related to the legitimacy theory and ‘communication’ itself can be used as an overarching framework to study corporate social reporting. Both ‘corporate image’ and
‘corporate identity’ are central in this framework. The main purpose of voluntary disclosure is providing information that legitimises company’s behaviour by intending to influence stakeholders (Hooghiemstra, 2000). Appendix 2 provides an conceptual overview of the legitimacy theory. The legitimacy theory is basically about a social contract between society and companies. If companies do not respect the ‘contract’, society will evoke the contract and the company cannot continue its operations. This part is comparable to the earlier mentioned ‘licence to operate’ (Qui et al., 2016). This is the ‘breakdown’ side of the contract. There is also a ‘contribution’ side within the
contract. On this side companies using social and environmental reports to publish their social and environmental responsibility and try to gain certain objectives which will be introduced in 2.1.
The society itself can also be seen as a stakeholder. According to Freeman (1994) a stakeholder is “any group or individual who can affect or is affected by the achievement for the organization’s objectives’’. Both the legitimacy theory and stakeholder theory are different but do have some shared characteristics, according to Hooghiemstra (2000) they may be viewed as overlapping perspectives. According to Beurden & Gössling (2008), corporate social responsibility and the stakeholder theory are a fundament in studies of business and society. Furthermore, this theory was the most used theory in the papers they analysed for their literature review about CSR and financial
performance. Therefore, also the stakeholder theory should be taken into account together with the legitimacy theory. The stakeholder theory says that managers need to take into account all interests of all stakeholder of the firm. So not only financial
stakeholders but also employees, customers, communities and even under some
interpretations, the environment (Jensen, 2010). Making decisions which are in the best
interest for every stakeholder and managing these relationships will determine the
eventual or final success of the company. According to Gössling (2003) society can
determine which responsibilities companies have towards stakeholders, therefore it is
also expected that companies are accountable for their social and environmental
performance. This applies to actions as well to outcomes of these actions (Freeman,
1994).
The relationship between the company and his shareholders is often affected by the so- called agency-problem (Barako, Hancock & Izan, 2006). This problem describes the information asymmetry between the agent and the principal. This relationship is defined as “a contract under which one or more persons (the principal(s)) engage another person (the agent) to perform some service on their behalf which involves delegating some decision-making authority to the agent” (Jensen & Meckling, 1976, P.
308). So, the agency theory and legitimacy theory are having both a ‘contract’
perspective.
When looking at a company, the manager can be classified as the agent and the
shareholder as the principal, were the agent acts on behalf of the principal (Barako et al., 2006). Possible conflicts which can occur due to this information asymmetry are
addressed in formal contracts between the shareholder and manager. Shareholders basically create mechanisms to monitor managers which reduce opportunism and information symmetry and eventually maximizes shareholders’ wealth (Iatridis, 2013;
Fields et al., 2001; Meek et al., 1995). In addition to the legitimacy and stakeholder theory, the agency theory is also a theory which is suitable for developing and testing hypotheses about corporate social disclosure (Ness & Mirza, 1991). If the ownership and management are separated, agency costs can occur. These agency costs are according to Jensen and Meckling (1976) the sum of:
➢ The monitoring expenditures by the principal: costs incurred by the principal to limit the aberrant activities for the agent
➢ The bonding expenditures by the agent: costs incurred to ensure that the agent does not undertake actions that are not in the principles ‘interests
➢ The residual loss: due to sub-optimisation by the agent of the welfare-
maximisation objective
2.2 Hypothesis development
The main research question is; ‘’How value-relevant is GHG-disclosure for shareholders and what is the moderation effect of GHG-intensity on this relationship? Therefore, I will introduce certain objectives the company is trying to reach by providing disclosure and how these objectives can affect financial performance. The aim of this section is to support the conceptual (figure 1.) model with theoretical substantiation.
At the contribution side of the legitimacy theory companies using social and
environmental reports to publish their social and environmental responsibility and try to reach certain objectives (appendix 2). These objectives are:
➢ To create a good image or reputation
➢ To conform the legitimacy of their operations
➢ To demonstrate regulatory compliance
➢ To gain marketing benefits from reputation for environmental protection
➢ To differentiate themselves from their competitors
Considering the first objective, Qui et al. (2016) found that firms with better, hence higher quality social disclosures have higher market values. The researchers argued that this relation exists due to a strong reputation effect. In addition, Iatridis (2013) found that high quality environmental disclosures improve investor perceptions. Furthermore, these disclosures provide a signal of transparency and enhance managers’ reputation and social profile (Deegan et al., 2006; Patel et al., 2002; Simnett et al., 2009). These results are in line with the first objective and furthermore are evidence that a higher quality of disclosure can be value relevant.
The objective of demonstrating regulatory compliance holds together with the
regulatory risk. Although disclosure about GHG is still voluntary, in Australia companies
are obligated to report GHG-emissions towards the government. It is also obligated for
obtaining the ISO-14001 certificate (Rankin et al., 2011). Yusoff, Yatim & Nasir (2005)
also found that most companies in Malaysia disclose environmental information to
obtain the ISO-14001 certificate. This certificate is further used to improve the relation
between the company and its stakeholders (Iatridis, 2013). Regulations can differ among
countries and can change during the years. The change of regulation is a risk itself. It is named the ‘future regulation risk’. This is a risk because it is possible that companies are not sufficient prepared for the future regulations and face extra regulation costs or even fines which has a negative effect on the future cash flows. Information about GHG- disclosure then would appear to have value when a company is able to revise the
likelihood of paying fines for being non-compliance (Deegan, 2004). Increasing societal and regulatory pressure causes investors to be more interested in environmental (and social) disclosures (Friedman & Milles, 2001; Cormier & Magnan, 2007). Rankin et al.
(2011) argue that large firms receive more attention from stakeholders and therefore provide more GHG-disclosure to mitigate the future regulation risk. Therefore, demonstrating regulatory compliance is an important objective of disclosing
information and can eventually mitigate future regulation risks. By mitigating this risk the expected cash flow of a company can be larger and/or the cash flow itself can be perceived less risky.
There is another second risk regarding GHG-emissions. During the years governments introduced carbon regulations to reduce GHG-emissions, such as a carbon tax in Australia, a carbon trading scheme in the EU (EU-ETS) and energy management in Indonesia (Rokhmawati et al., 2015). Also, in North America a patchwork of systems exists, these are designed by states due the absence of federal regulation (Kolk et al., 2008). At this moment, 75% of the emissions which are covered by pricing regulation is priced
2below $10 for 1 ton of CO
2(CDP, 2017). But the price of carbon has significant price volatility during the years. For example, in 2008 prices under the EU Emission Trading System were €30 and €10 lower than a year later (CDP, 2017). This price volatility is also a risk for companies.
Furthermore, the CDP made a visualisation (Appendix 1) of the expected price of carbon which is needed to meet the targets of the Paris Agreement.
As can be seen in this image they expect huge price increases during the next decades. Earlier I mentioned companies face a future regulation risk, in addition, companies face also a ‘future price risk’. So GHG-emission itself is a growing significant risk for companies, GHG-disclosure is important to identify these risks and to communicate it towards
stakeholders (The Greenhouse Gas Protocol Revised Edition). By reducing emissions, the company can influence the future price risk. The perception of stakeholders can be influenced by reporting about the company's’ plans of reducing emissions. The reduction target is part of the quality
measurement of disclosure within this research.
