Greenwashing undermines the credibility of environmental, social, and governance (ESG) reporting and diminishes its integrity. This diminishes the probability that people will trust the information presented, complicates decision-making processes, destabilizes financial markets, and undermines the quality of disclosures. This research utilizes a comprehensive literature review and bibliometric analysis to investigate the academic discourse around ESG disclosure and strategies to address corporate “greenwashing.” The study’s aims were accomplished using bibliometric analysis, employing the statistical programming tools R Studio, Biblioshiny, and VOSviewer. We obtained bibliometric data from the Scopus database for the period 2012–2024. We used the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) methodology, including both inclusion and exclusion criteria, to ascertain the optimal sample size. The research indicates that greenwashing is a multifaceted issue that may manifest in many forms, shapes, and intensities. This obstructs the advancement of technologies for prevention, measurement, and detection. Furthermore, the results indicate that greenwashing adversely affects sustainable finance, particularly green loans and bonds. Furthermore, the findings indicate that corporate greenwashing is a distinct kind of greenwashing.
