Environmental, social, and governance (ESG) practices are increasingly recognized as critical for corporate sustainability and market competitiveness, driven by heightened expectations from investors, governments, and consumers. This study examines the evolution of ESG practices among companies listed on the Brazilian Stock Exchange’s Corporate Sustainability Index (ISE B3) from 2005 to 2022. We analyzed the index portfolio’s composition, focusing on changes in ESG dimensions over time. The only six long-lived companies in this index, from retail, banking, and energy sectors, were selected for in-depth analysis. We further evaluated the quality and consistency of ESG disclosures in company reports. Findings indicate relevant fluctuations in the number of companies included in the ISE B3 and variations in ESG scores for the companies. These variations may be attributed to the voluntary nature of ESG practices and the absence of standard disclosure. This study reveals a lack of homogeneity in ESG reporting, which could be addressed by establishing more straightforward guidelines and global standards. This research underscores Brazilian companies’ challenges navigating diverse ESG frameworks to align with evolving societal and environmental expectations.
