An international study of carbon information asymmetry and independent carbon assurance

Protecting the environment is now a major aspect of corporate social responsibility. However, voluntary carbon disclosure includes private information on future sustainability that external stakeholders cannot easily verify. Drawing on information asymmetry theory, we predict that companies with higher carbon information asymmetry between insiders and outsiders have a greater incentive to voluntarily engage an external party for the independent assurance of their greenhouse gas statements. Using data from the CDP, we test this hypothesis and find that our proxies for carbon information asymmetry (e.g., greenhouse gas emissions, energy structure) are significantly associated with the adoption of carbon assurance. Further analyses suggest that the probability of carbon assurance is enhanced when carbon disclosure is inadequate to diminish information asymmetry. Finally, our sample companies adopted carbon assurance in addition to financial auditing. This highlights the key point that resolving carbon information asymmetry requires carbon assurance, which cannot be substituted for by financial auditing.     

Carbon disclosure,carbon performance and financial performance: International evidence

This study examines how carbon performance affects carbon disclosure and how carbon disclosure affects financial performance. With a sample of global firms, the study analyses how relationships between carbon disclosure, carbon performance and financial performance vary in institutional contexts. Our results show that carbon disclosure positively affects carbon performance, consistent with the signalling theory. We find that carbon disclosure negatively (positively) affects financial performance in the short-term (long-term). Our findings have significant implications for investors as some firms use carbon disclosure as part of impression management. Our results help regulators to monitor carbon disclosure and assist investors with investment decisions.     

Does voluntary carbon disclosure reflect underlying carbon performance?

Carbon information is becoming more and more important in the decision making of stakeholders, but there is growing concern regarding the reliability of corporate carbon disclosure and a lack of empirical studies addressing this issue. The purpose of this paper is to examine whether voluntary carbon disclosure reflects firms’ true carbon performance. Level of carbon disclosure was measured based on content analysis of Carbon Disclosure Project (CDP) reports, and our carbon performance index focused on both carbon intensity of emissions and carbon mitigation. Based on a sample of 474 U.S., U.K., and Australian firms, our findings show a significant positive association between carbon disclosure and performance, suggesting that firms’ voluntary carbon disclosure in the CDP is indicative of their underlying actual carbon performance. This result is consistent with signalling theory. Our findings are useful for corporate stakeholders and governmental policymakers who are concerned about the quality of voluntary greenhouse gas disclosure.     

Revisiting carbon disclosure and performance: Legitimacy and management views

With corporate disclosure of carbon emissions rapidly increasing, the long-standing question remains whether carbon disclosure has any influence on the improvement of carbon performance. Previous studies of environmental disclosure and performance have predominantly focused on whether disclosure is a substitute for poor performance. Little attention has been devoted to the more important question about how changes in disclosure may lead to subsequent changes in performance over time. Following the rationales taken by the legitimacy and management perspectives, we revisit the relationship between carbon disclosure and performance, with a focus on changes that disclosure may (or may not) create. Using a change analysis of Global 500 companies and their carbon emission and disclosure data released between 2008 and 2012, this study finds that the change in carbon disclosure levels is positively associated with a subsequent change in carbon performance (examined through direct and indirect carbon emission intensities). Thus, regardless of whether disclosure has been used as a legitimising tool for prior poor performance, this study confirms that carbon disclosure motivates companies and creates an ‘outside-in’ driven effect for subsequent change and improvement in carbon performance. However, the association between changes in carbon disclosure and performance is relatively weaker in high energy-intensive firms.     

The market value of decomposed carbon emissions

We introduce the decomposition of carbon emissions into an expected and an unexpected component and analyze the association between these components and firm value. The expected component captures a firm's average carbon emissions inherent to its business model and operating environment. The unexpected component, meaning the firm-specific deviation from expected carbon emissions, reflects the management's effort and ability to implement carbon management and actively influence carbon emissions. For a sample of US firms operating in carbon-intensive industries, we estimate the expected component using a regression of carbon emissions on firm characteristics and industry. The residual of this regression represents the unexpected component. The results reveal that, on average, investors attach value to both components. While investors consider the expected component to be relevant regardless of assurance, they consider the unexpected component to be more relevant in the presence of assurance. The assurance alleviates credibility concerns about the information content of the unexpected component. Additionally, we confirm the nomological validity of our measure of the unexpected component, as it is negatively related to indicators of better carbon management systems.     

The influence of institutional contexts on the relationship between voluntary carbon disclosure and carbon emission performance

This article examines the relationship between the level of voluntary carbon disclosure (VCD) and carbon emission performance and how the institutional context influences this relationship. Using a sample of Global 500 firms participating in the Carbon Disclosure Project (CDP) over the period 2008–2015, the evidence shows a negative relationship between voluntary carbon disclosure and carbon emission performance, which is consistent with the legitimacy theory that VCD may be undertaken for the purposes of legitimation. However, stringent carbon institutions appear to restrict legitimation attempts and help better reflect underlying performance.     

公司动机、审计师声誉和自愿性内部控制鉴证报告——基于A股公司2008—2009年年报的经验研究

上市公司是否自愿披露内部控制鉴证报告,不仅取决于公司自身的披露动机,而且取决于审计师是否愿意出具内部控制鉴证报告。本文利用沪深两市上市公司在2008—2009年年报中自愿披露内部控制鉴证信息所带来的研究机会,实证考察了内部控制鉴证报告这一特殊的自愿信息披露行为的决定因素。研究发现,降低代理冲突和传递信号不仅是上市公司自愿披露内部控制鉴证报告的主要动机,而且是其自愿提高鉴证信息披露质量(扩大鉴证范围和提高保证程度)的主要动机;审计师声誉越高,越不愿意出具内部控制鉴证报告和为公司的内部控制提供高程度保证;大股东与中小股东之间的代理冲突以及内部控制质量会显著影响审计师对鉴证风险水平的评估,进而影响内部控制鉴证报告的鉴证范围和保证程度。     

Climate governance effects on carbon disclosure and performance

Integration of carbon oversight into board structures and processes has the potential to improve carbon performance and demonstrate accountability to stakeholders. However, it is not clear how climate governance affects carbon disclosure. Contributing to two strands of the literature, sustainability and governance issues, this paper examines the combined impact of climate governance on carbon disclosure. We find climate governance is associated with alignment between carbon disclosure and carbon performance. The results suggest that climate governance also reduces over-acclaiming of good performance via extensive disclosure, and low-polluters disclose more to differentiate themselves. Our findings highlight the importance of the frequency of reporting to the board and time horizon of carbon reporting for improving carbon disclosure and carbon performance. In contrast to traditional governance mechanisms, our results suggest climate governance better reflects firms’ commitment to addressing sustainability issues and transparent reporting.     

Carbon Disclosure,Financial Transparency,and Agency Cost: Evidence from Chinese Manufacturing Listed Companies

Given the constraints on carbon emissions due to their impact on global warming, carbon disclosure has become an important way to deliver signals to the market. We examine the benefits associated with carbon disclosure from the standpoint of corporate social responsibility (CSR) for China’s manufacturing industries from 2010 to 2014. We divide corporations into heavily polluting and non-heavily polluting groups in order to control the industry factor. Based on the Principal-Agent Theory, we empirically test the relationship between carbon disclosure and financial transparency, and we evaluate the effect of carbon disclosure on agency costs and operations. Our results highlight that carbon disclosure is negatively associated with agency costs. However, we do not find enough evidence to prove what role financial transparency plays in the relationship between carbon disclosure and agency cost. Therefore, the influence of financial transparency as a mechanism is not yet clear. This study provides a way to look at the intentions of firms that disclose carbon information, and it also enhances the literature on carbon disclosure and agency costs in China based on Chinese data.     

Developing an Assurance Standard for Carbon Emissions Disclosures

A new assurance service on carbon emissions disclosures in Australia would provide an appropriate response by the auditing profession to the challenges posed by climate change. Recognising the difficulties in developing an assurance standard on broad sustainability information, this paper focuses on the case for developing a standard on the more specific issue of corporations' carbon emissions disclosures. Credibility of disclosure of carbon emissions and any associated trading scheme would be strengthened by the implementation and enhancement of assurance standards and services.     

Climate Change and Asset Prices: Are Corporate Carbon Disclosure and Performance Priced Appropriately?

This paper empirically assesses the relevance of information on corporate climate change disclosure and performance to asset prices, and discusses whether this information is priced appropriately. Findings indicate that corporate disclosures of quantitative greenhouse gas (GHG) emissions and, to a lesser extent, carbon performance are value relevant. We use hand‐collected information on quantitative GHG emissions for 433 European companies and build portfolios based on GHG disclosure and performance. We regress portfolios on a standard four factor model extended for industry effects over the years 2005 to 2009. Results show that investors achieved abnormal risk‐adjusted returns of up to 13.05% annually by exploiting inefficiently priced positive effects of (complete) GHG emissions disclosure and good corporate climate change performance in terms of GHG efficiency. Results imply that, firstly, information costs involved in carbon disclosure and management do not present a burden on corporate financial resources. Secondly, investors should not neglect carbon disclosure and performance when making investment decisions. Thirdly, during the period analysed, financial markets were inefficient in pricing publicly available information on carbon disclosure and performance. Mandatory and standardised information on carbon performance would consequently not only increase market efficiency but result in better allocation of capital within the real economy.     

The environmental disclosures of the electricity generation industry: a global perspective

The electricity generation industry has been under close regulatory and public scrutiny for decades for the significant impacts its activities have on the environment. The industry is responsible for a large proportion of greenhouse gas (GHG) emissions, which has intensified public and regulatory scrutiny of late. Therefore, electricity generation firms face immense pressure to show environmental responsibility. Firms respond with environmental disclosures in their annual reports, in stand-alone-reports, and on websites. In this study, we use comprehensive disclosure indices to measure the quality (or comprehensiveness) of the CO₂ emissions related disclosure and the overall environmental disclosure of 205 electricity generation firms in 35 countries. We find that firms in countries with a high commitment towards the environment and a carbon emissions trading scheme (measures of social concern for environmental protection and emissions), are likely to disclose more comprehensive environmental information. In addition, we find that firm size, age of the assets, listing status, and media exposure influence disclosure. Environmental performance, measured by CO₂ emissions, is not significantly related to environmental disclosure among our sample firms. The theoretical implication of these findings is that social beliefs (that are different in different countries) prompt a legitimating disclosure response from firms that is not significantly affected by their performance against that social belief.     

An Empirical Investigation of the Effect of CFO Power on Disclosure Quality

We examine the association between chief financial officer (CFO) power and disclosure quality, measured using financial statement disaggregation disclosure and analyst forecast disclosure. Empirically, we validate that CFO power, measured by multiple dimensions, is positively associated with firms’ disclosure quality. We also find that this positive association between CFO power and disclosure quality is stronger when firms exhibit higher governance monitoring and accounting quality. Further analysis shows that our main results hold across multiple disclosure quality tests. Our findings are robust to addressing endogeneity issues using two-stage least squares, Heckman selection bias, and propensity score matching analyses. The results highlight the importance of CFO power for the accounting reporting process and decision-making.     

Accounting for carbon and reframing disclosure: A business model approach

This paper contributes to the research in accounting and the debate about the nature of carbon footprint reporting for society. This paper utilises numbers and narratives to explore changes in carbon footprint using UK national carbon emissions data for the period 1990–2009 and six years (2006–2011) of carbon emissions data for the FTSE 100 group of companies and a case study that focuses on the UK mixed grocery sector. Our argument is that existing approaches to framing carbon disclosure generate malleable, inconsistent and irreconcilable numbers and narratives. In this paper we argue for an alternative framing of carbon disclosure informed by a reporting entities business model. Specifically, we suggest, that a reporting entity disclose its carbon–material stakeholder relations. This alternative, we argue, would increase the visibility of carbon generating stakeholder relations and avoid some of the difficulties and arbitrariness associated with framing carbon disclosure around a reporting entity boundary where judgements have to be made about responsibility and operational control.     

The relation between CEO equity incentives and the quality of accounting disclosures: New evidence

This paper provides new evidence on the negative relation between CEO equity incentives and accounting disclosure quality. We analyze a comprehensive set of disclosure quality variables, including discretionary accruals quality, the quantity and quality of voluntary disclosures, fineness of reported financial statement information, and the narrative quality of regulatory filings, and use them to create information disclosure quality indices. We address the potential endogeneity of CEO equity incentives by conducting two-stage least squares/IV models and natural experiments created by situations in which there is an exogenous shock to the use or value of CEO stock options. Our results are robust to subsample analyses and to alternative measures of the incentives created by CEO options.     

Accounting for climate change and the self-regulation of carbon disclosures

Adopting a form of “critical dialogic engagement” (Bebbington et al., 2007), this paper explores how dominant environmental discourses can influence and shape carbon disclosure regulation. Carbon-related disclosures have increased significantly in the last five years, and many of these disclosures remain voluntary. This paper considers both the construction of self-regulated carbon disclosure practices and the role that this kind of carbon information may have in climate change-related decision making. Our preliminary findings indicate that the methodological diversity underpinning carbon disclosures may inhibit the usefulness of climate change-related data. To explore these issues, this paper focuses on the Carbon Disclosure Project (CDP) and the use of the Greenhouse Gas (GHG) Protocol as a reporting model within it.     

The effect of disclosure committees on non-GAAP reporting quality

I examine whether company-implemented disclosure committees help to improve non-GAAP reporting quality. I find that firms with disclosure committees provide higher quality non-GAAP performance metrics and that the exclusions used to calculate their non-GAAP numbers are less persistent for future operating income and operating cash flows. Moreover, I find that firms with disclosure committees are less likely to receive SEC comment letters about non-GAAP disclosure. For firms that receive comment letters about non-GAAP reporting, disclosure committees can help to improve non-GAAP reporting quality. Comparing the influence of audit committees and disclosure committees, I find that audit committee financial experts have stronger monitoring effects than those on disclosure committees. Meanwhile, legal experts on disclosure committees provide similar monitoring compared to audit committees’ financial experts. Finally, the interaction between audit committee financial experts and disclosure committee legal experts produces the strongest effect on non-GAAP reporting quality. In sum, my analyses suggest that disclosure committees can provide important monitoring of non-GAAP reporting.     

Market reactions to a cross-border carbon policy: Evidence from listed Chinese companies

The effects of cross-border carbon policy have attracted increasing attention worldwide. We investigate the reaction of the Chinese stock market to the announcements of 12 legislative events associated with the European Union Carbon Border Adjustment Mechanism (EU CBAM). Our results, based on all industrial companies listed on China's Shenzhen or Shanghai Stock Exchanges, show that Chinese companies that export their products to the EU experience a more negative cumulative abnormal return around EU CBAM events than their counterparts (non-export companies and non-EU export companies). A cross-sectional analysis reveals that negative stock market reactions to the legislative events are greater when companies have greater carbon emissions intensity. Our further analyses show that being listed in both A-share and H-share markets, participating in a carbon emissions trading scheme, and having intensive cross-border collaboration mitigate the adverse market reactions. Our results show that the Chinese market is sensitive to legislative announcements associated with this cross-border carbon policy.     

Determinants and consequences of voluntary corporate social responsibility disclosure: Evidence from private firms

We examine whether and how private firms differ from public firms in determining corporate social responsibility (CSR) disclosure policies. We document that private firms are less likely to issue CSR reports compared with their public peers. Adopting a bivariate probit model that accommodates partial observability, we find that the effect is mainly driven by a supply-side force rather than a demand-side force. From a debtholder-oriented perspective, while public firms enjoy more favorable credit ratings and a lower cost of debt due to CSR disclosure, private firms do not reap similar benefits from CSR disclosure. Corporate governance and CSR assurance alleviate debtholders' concern on private firms’ engagements in CSR.     

Carbon disclosure,emission intensity and cost of equity capital: multi-country evidence

This study examines the joint effect of carbon disclosure and greenhouse gas (GHG) emissions on firms’ implied cost of equity capital (COC). Based on 4655 firm-year observations across 34 countries, we find firms’ GHG emission intensity to be positively associated with COC. However, we find also that the penalty linked with higher COC is moderated by extensive carbon disclosure. We provide evidence that the extent of carbon disclosure helps reduce the premium required by investors to compensate for poor carbon performance. Our study provides insights to policymakers, investors and managers on the combined effect of carbon disclosure, and emission intensity.
