The purpose of this study is to explore the effect of managerial ability on voluntary environmental, social and governance (ESG) disclosure and assurance. By focusing on managerial ability, this study provides a more nuanced understanding of the factors influencing a firm’s ESG disclosure and assurance practices. This study contributes to a relatively unexplored area of study regarding the role of top management in promoting ESG reporting.

This study draws on a sample of publicly listed firms from 2014 to 2019 in Taiwan and applies the data envelopment analysis method to measure managerial ability. Heckman’s (1979) two-step model is used to estimate the primary models to prevent the results from being affected by possible bias because of self-selection.

The empirical evidence suggests that managerial ability is positively related to voluntary ESG disclosure and intention to seek third-party assurance of the report. Overall, managerial ability determines whether a firm will use voluntary ESG disclosure and assurance as a corporate strategy to respond effectively to stakeholders’ needs. The findings are robust after using alternative measures of managerial ability.

Investors and other stakeholders keen on seeking ESG information offered by companies could find the findings of this study valuable. By better comprehending how managerial competence impacts voluntary ESG disclosure and assurance, stakeholders may be better equipped to hold companies responsible for their ESG disclosure practices and make informed investment decisions.

In the ESG decision-making process, managers with better abilities have a higher tendency to use voluntary disclosure and assurance as a part of the company’s sustainable policy.

Unlike previous studies of the determinant factors of ESG disclosure, which mainly explore factors at the national or corporate level, this study focuses on factors at the individual level (i.e. managerial ability) to fill the gap in the literature. This study also presents empirical evidence that corroborates the idea that managerial competence can influence not only ESG disclosure but also the voluntary assurance of ESG information.

This paper aims to investigate whether providing voluntary external assurance on voluntary environmental information by firms operating in environmentally sensitive industries (ESI) is relevant in terms of market value. It also examines how various characteristics of assurance statements (i.e. level of assurance, scope of assurance and provider of assurance) affect the value-relevance of environmental disclosure by ESI firms.

To mitigate the endogeneity problem, the authors use the two-step generalized method of moments estimation approach.

Focusing on annual and social reports of French companies listed in the SBF120 index, results show that environmental disclosure by ESI firms and its assurance are destructive in terms of market value. Moreover, while providing a broader scope of assurance and having a professional accountant as the assurance provider enhance the value relevance of environmental reporting of the whole sample, this is unlikely to be the case for ESI firms. In particular, a higher level of environmental disclosure is financially rewarded by market participants for ESI firms that provide a higher level of assurance.

The study provides a better understanding of the circumstances under which market participants assign value to voluntary environmental information disclosed by companies operating in ESI. It also provides insights into the value added to different characteristics inherent in the quality of assurance provided with regard to environmental disclosure.

The study indicates that the institutional context of the relationship between the firm and its shareholders influence the value obtained from assurance. Results provide value insights regarding cultural and legal dimensions of environmental reporting.

The study extends the prior literature on the capital market benefits of voluntary assurance practices by focusing on the French legal environment. France can be considered as a new institutional context that has been little addressed by the existing literature.

The purpose of this study is to consider three distinct bodies of literature and uses stakeholder theory as the premise of this study. The first deals with corporate sustainability reporting and voluntary disclosure behaviour, and corporate governance at the firm level, the second deals with the decision to utilize assurance services (voluntary adoption) and the third relates to the choice of auditor/assurance provider.

This study investigates these issues using archival data from some of the Top 200 listed companies in 2010 from the countries Australia and the UK. The final matched-pair sample consists of 220 listed companies.

The study finds that audit client size and the strength of corporate governance structures are significant in explaining the decision to produce a standalone sustainability report. Whereas few of these variables provide any explanatory value on the voluntary decision to assure the sustainability report, the existence of an active and diligent audit committee does have positive significance. Finally, the existence of an active and diligent sustainability committee is significant in explaining the choice of assurance provider where a member of the auditing profession was selected by the firm’s management.

Few studies (if any), have found a link between governance characteristics, sustainability report production, and assurance provider. The current study attempts to address this knowledge gap, and also considers the assurance work by professionals outside the auditing profession, and identifies which governance and firm-level characteristics may explain demand for their assurance services. This current study, assists to understand the low incidence of assurance and what might be necessary to increase demand for this type of assurance.

Despite its voluntary nature, the Johannesburg stock exchange (JSE) requires all listed companies to apply the King III principles, including providing independent CSR assurance. King III has accordingly made independent CSR assurance a de facto mandatory requirement, albeit on an “apply or explain” basis. The purpose of this paper is to examine the impact mandatory corporate social responsibility (CSR) assurance practices in South Africa, within a King III context.

To understand the impact of King III on South African CSR assurance practices, a longitudinal study covering reporting periods both before and after King III implementation. The first stage reviewed the annual reports of the 200 largest JSE-listed companies to establish the frequency of CSR assurance provision. The second stage involved performing a content analysis on the CSR assurance reports.

King III is driving the institutionalisation of CSR assurance practices in South Africa, as evidenced by the growth in CSR assurance since the implementation of King III. The study also found that the audit profession’s dominance was being eroded by specialist CSR assurors providing higher levels of assurance, despite concerns about the rigour of their assurance methodologies. Voluntary CSR assurance practices have resulted in the inconsistent application of CSR assurance practices, impairing the ability of stakeholders to understand the nature and scope of CSR assurance engagements. It is argued that this deficiency may be overcome through the imposition of a mandatory CSR assurance regime.

The pervasive impact of the King Code of Governance on South African organisations makes it appropriate to examine its impact on South African CSR assurance practices. As such, this paper represents one of the first studies to specifically consider the impact of a mandatory regulatory requirement for independent CSR assurance and suggests a future direction for global CSR assurance practices.

Credibility concerns regarding integrated reports can harm the intended decrease of information asymmetry between a firm and its investors. Therefore, it is crucial to examine whether voluntary third-party assurance enhances the credibility of integrated reports and, thus, decreases information asymmetry. Furthermore, this study aims to investigate the interaction effect between assurance quality and the disclosed connectivity of the capitals, a distinguishing feature of integrated reports.

Content analysis is performed of the 176 assurance statements included in the 269 integrated reports of Forbes Global 2000 firms disclosed from 2013 to 2015 and the 269 integrated reports themselves. Regression analyzes are applied to examine the associations between assurance, the disclosed connectivity of the capitals and information asymmetry.

The presence of an assurance statement in an integrated report significantly decreases information asymmetry. Surprisingly, assurance quality is not significantly associated with information asymmetry. However, an interaction analysis reveals that combining high assurance quality with high disclosed connectivity of the capitals allows a significant decrease in information asymmetry.

The paper demonstrates that the connectivity of the capitals of integrated reports and assurance quality are connected and together are associated with information asymmetry.

The results imply, both for report preparers and standard setters, that assurance quality is advantageous only when combined with disclosed connectivity of the capitals.

More information on non-financial information measured by the connectivity of the capitals of integrated reporting has an interaction effect together with assurance quality on information asymmetry.

This paper builds on a unique data set derived from the contents of integrated reports and accompanying assurance statements. Furthermore, it extends the integrated reporting literature by investigating the interaction between assurance quality and the disclosed connectivity of the capitals, which had not previously been examined in combination.

This study aims to provide a snapshot of voluntary sustainability assurance in New Zealand (NZ) in 2020. we assess the frequency of different assurance elements and discuss aspects of current practices that potentially contribute to the audit expectation gap. we also test whether the determinants of voluntary sustainability assurance in NZ are consistent with international findings.

For 118 companies listed on the New Zealand Stock Exchange in 2020, we hand collected data on whether sustainability information was assured, subject matter assured, assurance level, outcome, provider, disclosure of detailed procedures, standard referenced and criteria applied. we then examine the influences of voluntary sustainability assurance using both univariate and regression analysis.

Approximately 20% of listed companies that disclosed sustainability information provide a sustainability assurance report, indicating low levels of assurance compared to international practices. we note that the presence of different forms of assurance and certification, placement of sustainability information before financial statements and the associated audit report and mixture of assurance levels potentially contribute to the audit expectation gap. Further, voluntary sustainability assurance practices are diverse, and there are notable differences between Big Four accounting firms and other providers in terms of assurance level and standard referenced. Consistent with prior studies, we find size and industry classification as two main drivers of voluntary sustainability assurance.

We contribute NZ-specific insights to the sustainability assurance literature. The findings on voluntary sustainability assurance practices and reflection on the audit expectation gap are timely and relevant to the new climate-related disclosure mandate and pending assurance requirements.

The purpose of this study is to examine whether different levels of assurance statements of environmental disclosures affect investment choices in the French context where environmental assurance was voluntary until 2012 and became regulated and mandatory since then.

The authors conducted an experiment during the voluntary context – which represents the vast majority of countries – on a sample of 108 financial analysts.

Environmental disclosure has a positive impact on investment recommendations. More surprisingly, financial analysts are less likely to give recommendations in favor of a company that displays environmental disclosure with low-level assurance than for a company with no assurance statement at all.

When assurance is voluntary and there are at least two levels, this study results suggest that firms should avoid selecting the lowest level of assurance because it negatively affects investor decisions. From this perspective, firms should devote sufficient effort and resources to obtain at least Level 2 environmental disclosure assurance.

Given the recommendations made by financial analysts, the authors could expect that firms may prefer to engage in a higher level of assurance or to provide no assurance rather than minimize their financial efforts and resources to select a lower level of voluntary assurance regarding environmental disclosure.

This study has implications for the voluntary assurance practices of environmental disclosure and can provide support to regulators to promote higher standards in environmental assurance. It documents the relevance to increase the level of requested assurance for environmental disclosure.

To the best of the authors’ knowledge, very few studies have examined the additional effect of assurance on environmental disclosure in investors’ decisions. The experiment is conducted with financial analysts in the context of voluntary assurance.

The purpose of this research is to examine the impact of external assurance on the level of voluntary corporate climate change disclosures by Finnish firms.

The sample of this study includes 228 firm-year observations over the period 2008–2015 for listed Finnish companies that have issued sustainability reports and responded to the Carbon Disclosure Project (CDP) questionnaire at least once during the sample period. The authors conduct a panel regression analysis to study the afore-mentioned linkage. In addition, the Tobit regression model is also estimated to check the robustness of our findings.

The findings suggest that assurance has a highly significant positive impact on the level of corporate climate change disclosures even after controlling for the effect of a number of control variables. Moreover, among the control variables, firm size and asset age are found to have significant effect on the extent of carbon emissions disclosure. Furthermore, the additional analysis reveals that the type of assurance providers (accounting firms vs non-accounting firms) and the type of financial auditors (Big4 financial auditors vs non-Big4 financial auditors) do not influence the level of climate change disclosure of assured companies.

This research is subject to certain limitations. First, the source of the data used in this research is the CDP database which has limitations in that it is a voluntary disclosure process where all the observations collected are self-reported by the responding firms. This may bias the reported findings. Second, our sample includes only listed companies and hence the results might have limited explanatory capacity for unlisted firms.

By using the results of this research, corporate managers will be able to reduce the information asymmetry between various stakeholders and them through disclosure of accurate, reliable and credible environmental information. Such disclosures will, in turn, allow socially responsible investors to choose eco-friendly investments and will thus enable them to make appropriate investment decisions.

Research on the external assurance-corporate climate change disclosure nexus is scarce. This study addresses this gap in the nonfinancial disclosure assurance literature by demonstrating that external assurance increases the level of voluntary corporate climate change disclosure. Drawing on stakeholder-agency theory, this study views external assurance as a monitoring structure that potentially curbs the monitoring problem between corporate managers and other stakeholders and increases the amount of climate change disclosures making a possible avenue for the reduction of the information asymmetry between them.

This study aims at providing a proof of the factors associated with sustainability assurance demand by French companies.

This research used panel data methodology.

The study results demonstrate that institutional ownership and the presence of corporate social responsibility (CSR) committee within the management board have an effect on the demand for sustainability assurance. The results also reveal that three types of stakeholders (employees, environment and customers) positively affect the demand of voluntary sustainability assurance.

The paper provides a preliminary proof on the effects of the governance of corporation and pressure of some groups of stakeholders on the voluntary demand of sustainability assurance in France.

The market for the assurance of carbon emissions disclosures is showing intensive growth. However, due to the largely voluntary nature of carbon reporting and assurance, there are currently no clear standards or guidelines and little is known about it. The purpose of this paper is to examine the reporting and assurance practices for carbon emissions disclosures.

This study provides evidence on this market, with a sample that includes 13,419 firm-year observations across 58 countries between 2010 and 2017 from the Carbon Disclosure Project (CDP) database.

The results show that the demand for carbon emissions reporting comes mainly from North America, the UK and Japan. Recently, markets such as South Africa have also shown increased demand for carbon reporting. The data also shows that more firms are seeking assurance for their carbon emissions reports. Legitimacy, stakeholder and institutional theories are used to explain the findings of this study.

The results have important implications for firms that produce carbon emissions disclosures, assurance service providers, legislators, regulators and the users of the reports and there should be more specific disclosure guidelines for level and scope of reporting.

Amongst the firms that do provide assurance on their carbon emissions reports, a majority do so using specialist assurance providers, with only limited assurance being provided. The results further show that a myriad of assurance frameworks is being used to assure the carbon emissions disclosures.
