This study investigates whether carbon media legitimacy is influenced by carbon performance and/or carbon disclosure using a direct measure of carbon media legitimacy in UK context.

To test this study's hypotheses, the authors employ Tobit regression analysis of 95 UK companies listed in FTSE350. The authors use balanced panel data (475 observations in total) to reduces the noise introduced by unit heterogeneity.

The authors find that while corporate carbon performance is not reflected in carbon media legitimacy, carbon media legitimacy is positively and significantly affected by voluntary carbon disclosure (irrespective of its quality). Thus, voluntary carbon disclosure is shown to be an effective tool in legitimising corporate activities.

The results show a certain degree of naivety on the part of the media in assessing corporate carbon behaviour, since it values carbon disclosure (irrespective of its quality) more than carbon performance. Such media behaviour may hinder future improvement in carbon performance of firms.

This study's results indicate that the existing UK carbon disclosure policy does not address the heart of climate change and global warming. Thus, tougher regulations should be considered by policy-makers in relation to voluntary carbon disclosure in the UK.

To the best of the authors' knowledge, this is the first study to examine whether carbon media legitimacy is associated with both carbon performance and carbon disclosure using a direct measure of carbon media legitimacy, and to use the UK context when addressing this association. It also examines the effectiveness of quality of carbon disclosure as legitimation tool.

This study aims to propose a longitudinal analysis of motivations for Integrated Reporting (IR) adoption, internal changes, the benefits of IR implementation and compliance challenges.

The authors analyse a longitudinal case study of an Italian-listed company (Eni) participating in the IR-Pilot Programme (PP) and covering 10 years of IR adoption. The analysis was based on a mixed-method approach that included semi-structured interviews, content analysis of annual reports and triangulation with other data sources. Results are discussed regarding institutional theory, legitimacy theory and diffusion of innovation theory.

The study suggests that motivations for adopting IR change over time and participation in the IR-PP helps Eni acquire a comprehensive and substantial integrated view of value creation over time, makes integrated culture a key factor for strategic business sustainability and confirms the readiness of early adopters to comply with the non-financial Directive (NFD).

This study, among the few longitudinal case studies, provides organisations, regulators and academics with insights into the motivations driving the successful adoption and implementation of IR and the NFD. The results may help companies consider one of the tools currently deemed to bring sustainability into action and participation in pilot groups.

This study examines the effect of the environmental sensitivity of firms on the relationship between integrated reporting (IR) quality and sustainability performance. Prior research works focus on the nexus between IR quality and sustainability performance with little attention to factors that moderate this relationship.

Ordinary least squares (OLS) and other robust estimations are employed to analyse the data of firms on the Johannesburg Stock Exchange (JSE).

This study finds a positive association between IR quality and sustainability performance. However, the strength of this relationship is found to be weaker among environmentally sensitive firms, thereby raising concerns that such firms may be reporting less sustainability information with the mandatory implementation of IR on the JSE.

The findings highlight the need for regulatory bodies to consider additional sustainability disclosure requirements for firms in environmentally sensitive industries.

The findings should make regulatory bodies aware of the possible actions of environmentally sensitive firms in relation to sustainability information within a mandatory setting of IR.

The study extends the existing literature on IR and sustainability performance by considering the effect of firm environmental sensitivity as a moderating factor.

Reacting to the calls in the contemporary literature to further examine the relationship between board attributes and firms’ decisions to obtain corporate social responsibility assurance (CSRA) through the use of pioneering techniques, this study aims to analyse the influence of such attributes together with the existence of a corporate social responsibility (CSR) committee on the adoption of CSRA using fuzzy set qualitative comparative analysis (Fs-QCA).

Fs-QCA was performed on a sample of nonfinancial European companies listed on the STOXX Europe 600 index over the period 2016–2018.

The study findings indicate that the decision to obtain a CSRA report depends on a complex combination of the influence of the CSR committee and certain board attributes, such as size, experience, independence, meeting frequency, gender and CEO separation. These attributes play essential contributing roles and, if suitably combined, stimulate the adoption of CSRA.

The study findings are important for policymakers, professionals, organisations and regulators in forming and modifying the rules and guidelines related to CSR committees and board composition.

To the best of the authors’ knowledge, this study represents the first examination of the impact of board attributes and CSR committees on the adoption of CSRA using Fs-QCA method. It also offers a novel methodological contribution to the board-CSRA literature by combining traditional statistical (logistic regression) and Fs-QCA methods. This study emphasises the benefits of Fs-QCA as an alternative to logistic regression analysis. Through the use of these methods, the research illustrates that Fs-QCA offers more detailed and informative results when compared to those obtained through logistic regression analysis. This finding highlights the potential of Fs-QCA to enhance our understanding of complex phenomena in academic research.

The globalisation of supply chains has contributed to modern slavery by degrading labour standards and work practices. The inherent difficulties involved in monitoring extremely fragmented production processes also render workers in and from developing countries vulnerable to labour exploitation. This research adopts a benchmark methodology that will help examine the inherent modern slavery challenges.

This study examines how the benchmark model, including governance, risk assessment, purchasing practice, recruitment and remedy of victims, addresses supply chain modern slavery challenges. The proposed hypotheses are tested based on the reoccurring issues of modern slavery in global supply chains.

Estimations suggest that modern slavery is a growing and increasingly prominent international problem, indicating that it is the second largest and fastest growing criminal enterprise worldwide except for narcotics trafficking. These social issues in global supply chains have drawn attention to the importance of verifying, monitoring and mapping supply chains, especially in lengthy and complex supply chains. However, the advent of digital technologies and benchmarking methodologies has become one of the existing key performance indicators (KPIs) for measuring the effectiveness of modern slavery initiatives in supply chains.

This review provides an understanding of the current situation of global supply chains concerning the growing social issue of modern slavery. However, this includes various individual specialities relating to global supply chains, modern slavery, socially sustainable supply chain management (SCM), logistic social responsibility, corporate social responsibility and digitalisation. Furthermore, the review provided important implications for researchers examining the activities on benchmarking the effectiveness of the existing initiatives to prevent modern slavery in the supply chains.

This study aims to investigate the effect of the classification of origin country of institutional shareholder (domestic, developed and developing country) and its status on stock exchange (listed and unlisted) on environmental disclosure level in Indonesian companies.

The data set comprises 474 non-financial firms listed in Indonesian Stock Exchange (IDX) for the period of 2017 to 2019. The study uses an environmental disclosure checklist to measure the extent of environmental disclosure in companies’ reports. Panel regression analysis technique is adopted to investigate the association between total percentage of shares held by institutional shareholders based on the classification of origin country and the status in stock exchange, and the extent of environmental disclosure.

The study reveals that the extent of environmental disclosure is positively and significantly associated with institutional investors from domestic, developed countries, listed and unlisted institutional investors. Further analysis shows interesting results that institutions from developing countries have a negative and significant relationship with environmental disclosure in non-sensitive industries.

The authors recognize the issue of authors’ subjectivity in the measurement process of environmental disclosure. The sample for this study encompasses Indonesian listed firms. Thus, the results may not be generalized to Indonesian unlisted firms and other countries or regions.

This study suggests managers to engage more with institutional shareholders because they have greater concern for environmental disclosure practices. The current study also suggests managers to make strong environmental policies as they are important to ensure that institutional shareholders’ investments are safe.

Given the positive impact institutional shareholders have on the level of environmental disclosure, it indirectly indicates that institutional shareholders have a strong motivation to make the world a better place.

This study offers in-depth insights into the effect of institutional ownership on environmental disclosure based on the classification of origin country and listing status of institutional investors.

This paper aims to investigate the potential influence of managers on sustainability assurance. When the quality of sustainability reporting is questionable because of subsequent restatements, the authors explore whether assurance is used to enhance its credibility as a legitimization tool or as an impression management strategy. Additionally, the authors analyze how capital markets react to this potential managerial capture and, particularly, whether investors penalize this practice through the cost of capital.

Using an international sample from 2012 to 2016 and panel data regressions, this study relies on DICTION’s master variables of optimism and certainty to examine the impact of managers on assurance and the market’s reaction to these practices.

The study shows that some managers might use assurance as a legitimization tool rather than as a means of reinforcing the credibility of sustainability reporting. In such cases, the results reveal that investors penalize (reward) managerial influence (no influence) on assurance.

The new findings help companies understand that they will not improve their financing terms if investors perceive that managers have influenced assurance. Moreover, these findings emphasize the need for standardization to clarify assurance criteria and prevent managerial influence.

Managerial influence on assurance raises doubts about its value in terms of reducing information asymmetry and especially improving investors’ decision-making.

The present study represents the first evidence of the potential use of assurance for non-informative purposes. The authors provide clear evidence of how investors penalize managerial influence on assurance, in contrast to the mainstream literature, which shows that this practice always improves investors’ decision-making and is rewarded.

This study aims to evaluate the quality of the energy efficiency disclosures made by Australian cities. As cities are significant energy users, and energy use is a crucial source of greenhouse gas emissions, energy efficiency initiatives can play an essential role in addressing climate change. Yet, little is understood about the energy efficiency disclosures being made.

The authors developed an original energy efficiency disclosure index to assess the reporting quality of the eight largest Australian cities. The websites of these cities were analysed for information on energy efficiency measures from December 2018 to June 2019. Annual reports, environmental reports, climate action plans and any other material related to energy plans were downloaded and then coded using the index.

While all cities provided energy efficiency information, little financial information was provided, limited forward-looking information was disclosed, key challenges were not disclosed, and each city provided energy efficiency disclosures differently. Collectively, these findings demonstrate that public accountability is limited.

An important implication is the need to standardise and improve cities’ energy efficiency reporting, especially concerning financial information. Cities, governments and the Carbon Disclosure Project (formerly the CDP) could achieve this, perhaps as part of the broader update of the CDP city-focused guidelines for greenhouse gas (GHG) reporting.

Although some studies on GHG reporting by cities have already been undertaken, including energy efficiency as part of their disclosure index, no study has focused on energy efficiency disclosures. The authors provide original insights concerning these practices. The study also provides an energy efficiency disclosure index that can be used in further research.

This study aims to examine whether there exists any relationship between corporate biodiversity reporting decision (CBRD) and corporate environmental performance (CEP).

The primary sample contains 442 firm-year observations over a period of 13 years (2008–2020) for 34 listed Finnish companies. Based on both legitimacy theory and voluntary disclosure theory, 2 logit regression models are estimated to test the CBRD–CEP nexus. CBRD is a dichotomous variable. Three proxies for CEP, namely propensity to emit greenhouse gas (GHG), propensity to consume water and propensity to generate waste are employed.

This study finds that firms having higher propensity to consume water and generate waste are inclined to release biodiversity-related information. The findings support legitimacy theory suggesting that firms with inferior environmental performance may decide on reporting biodiversity information for legitimation purpose.

The study uses Finnish data and hence, the results may lack in generalizability to other national contexts.

The results of this study should be valuable to policy makers for formulating mandatory biodiversity reporting standards to ensure disclosure of standard, extensive and authentic biodiversity-related information by companies. The results should also be valuable to corporate managers and eco-friendly investors.

Corporate biodiversity reporting (CBR) is an under-researched area of environmental accounting literature. Using the Finnish context, this paper extends the existing literature by investigating whether any association exists between CBRD and CEP, which has not been examined before.
