This paper aims to investigate the latest scientific developments, map research networks and topics, and present a critical analysis of the gaps and future opportunities in the literature on the readability of sustainability reports. Through data collection and filtering processes, the final sample included 10 articles. Then, a bibliometric analysis was developed using Scopus metrics and AJG classification. VOSviewer software (Version 1.6.18) was used to develop bibliometric networks. Finally, we developed a systematic review analysis to answer our third objective. The results show that most studies on the readability of non-financial reports come from Europe and Oceania; the sample’s co-citations per author were classified into three clusters; most of the sample was linked to analyzing the quality and effectiveness of sustainability reports; and organizations tend to use low readability in sustainability reports. This study contributes to further scientific knowledge about the readability of sustainability reports and impression management techniques and to the research into the importance of sustainability reporting for managing stakeholder impressions. A wide range of implications for the academic community, regulatory bodies, organizations, and all users of the information disclosed through sustainability reports were identified. The main limitations may have been created by the sample’s size, exclusion criteria, and keywords selected.

Purpose: The purpose of this paper is to provide empirical evidence regarding the classification of European countries based on accounting quality metrics. The authors investigate whether the grouping of countries based on accounting quality levels differs from other classifications based on accounting practices or country-specific factors identified in previous studies.Design/methodology/approach: The authors run panel data regressions for 2.078 European listed companies using value relevance and earnings smoothing metrics. The authors also apply cluster analysis to classify the countries.Findings: The results suggest that the adoption of a common set of International Financial Reporting Standards (IFRS) did not lead to a similar level of accounting quality of financial information. The authors identified three clusters of countries that are not coincident with previous classifications.Research limitations/implications: The results show that the adoption of different accounting practices allowed in IFRS does not necessarily influence accounting quality.Practical implications: The results suggest that the way regulators decided to incorporate IFRS into national accounting systems is one issue that may be relevant in explaining the three clusters.Originality/value: The paper provides empirical evidence that supports two theoretical assertions. The first is that a classification depends entirely on the characteristics used to represent the countries being classified. The second is that the adoption of a single set of accounting standards does not determine similar accounting practices and does not lead to similar levels of accounting quality.

Purpose: The purpose of this paper is to investigate whether the introduction of water security, in 2015, as a category in the Carbon Disclosure Project (CDP) Climate A-List, increases the use of impression management (IM) strategies. The purpose is to analyze how companies reacted to programmes of voluntary disclosure of environmental information. Design/methodology/approach: Mixed-methods research was developed, combining a qualitative and quantitative approach. This study first used a qualitative content analysis of 15 companies’ reports, from the materials sector, which was scored in the CDP Climate A-List, in 2017, to identify the IM strategies adopted. Next, this study conducted a quantitative analysis to test the mean differences of water references between years, industry and region. Findings: Three types of IM strategies are identified (justification and commitment, self-promotion and authorization). The references identified as self-promotion strategy increased in 2016. This indicates companies reacted to the programmes for voluntary disclosure of environmental information by increasing strategies of legitimization and image promotion. Research limitations/implications: Further research can be developed, focusing only on sustainability reports and extending the number of companies, the period and sectors under analysis. Originality/value: This paper shows how the inclusion of a topic such as water security in an environmental ranking of companies, namely, CDP A-List, affects the use of IM strategies in voluntary disclosures.
