Adoption of sustainability reporting (SR) is growing consistently and 96% of the world's largest 250 companies now report on sustainability, leading to an increased research interest in this topic. However, studies on SR for identifying major themes, prominent authors, journals and countries are limited in number. Our study conducts a systematic literature analysis to structure the extant literature on sustainability reporting and provides an orientation for the researchers as well as industry experts. Findings show that Journal of Cleaner Production, Sustainability and Journal of Business Ethics are the most contributing journals while Australia, England and the USA are the leading countries. Olivier Boiral is the most productive author in terms of publishing articles and Rodrigo Lozano is the most cited author. GRI, CSR, assurance, stakeholder engagement are the most prominent themes while SDGs, firm performance, quality and materiality are the recent trends in sustainability reporting research area. We have also identified the research contexts (theories, determinants, industries) of current SR literature and suggested future research themes accordingly.
