This study examines sustainability reporting and greenwashing through a bibliometric analysis of research published in G7 and non-G7 countries from 2003 to 2022. It identifies three dominant themes: (1) greenwashing (exaggeration of green efforts), (2) ESG disclosures and performance gap, and (3) communicative legitimation strategies and reporting of negative aspects. The analysis reveals differences in research focus between G7 and non-G7 countries, with G7 countries showing more emphasis on greenwashing and ESG disclosures, while non-G7 countries highlight the role of institutional, cultural, and socioeconomic factors in greenwashing. The study highlights the need for further research on greenwashing in non-G7 countries, including the use of technology to detect greenwashing, the role of regulatory and governance frameworks, and the impact of greenwashing on corporate reputation and credibility. The findings suggest that greenwashing is a growing concern in sustainability reporting, and that global standards are needed to address this issue. The study also emphasizes the importance of transparency and genuine commitment to sustainability in corporate reporting to prevent greenwashing and promote responsible business practices. The research has practical implications for policymakers, corporate managers, and stakeholders, highlighting the need for improved reporting frameworks, regulatory oversight, and education to combat greenwashing and enhance the quality and credibility of sustainability reporting.This study examines sustainability reporting and greenwashing through a bibliometric analysis of research published in G7 and non-G7 countries from 2003 to 2022.
