The Global Reporting Initiative (GRI) is a non-profit organization that develops and publishes guidelines for reporting on economic, environmental, and social sustainability. The organization was founded in 1997 and has since become the de facto global standard setter for sustainability reporting. GRI's goal is to help companies and other organizations report on their sustainability performance in a transparent and consistent manner. The organization offers a range of tools and resources to help companies develop and report on their sustainability performance, including the GRI Standards, which provide a framework for reporting on sustainability issues. GRI also offers training and certification programs for sustainability professionals.
