Corporate sustainability reporting has evolved through time from a nice gesture or philanthropism to a necessity for a successful company. Companies are increasingly under pressure from stakeholders, investors, regulatory bodies, and consumers to adopt sustainable practices. Corporate sustainability reporting is no longer an option but a strategic necessity for companies that wish to thrive in a constantly evolving world. Nowadays, a reel needs for standardized high-quality sustainability language, as robust and widely recognized as language for financial language. Corporate sustainability reporting has known in the past decades a rise in number and in fame from all parties. However, bibliometric literature review on this topic remains limited. This paper aims to discuss and answer many questions from the emergence of corporate sustainability reporting to their evolution until today; it advances our understanding of corporate sustainability reporting, clusters and maps academic literature, and attempts to give a roadmap and research agenda for future research. Using a rigorous search protocol, we gathered 869 articles from the Web of Science (WoS) database between 2014–2025 and conducted a bibliometric analysis via Biblioshiny also known as “Bibliometrix 3.0 package”. This analysis highlights influential authors, institutions, and key trends, offering valuable insights for scholars and practitioners.
