The Global Reporting Initiative (GRI) is a non-profit organization that promotes economic sustainability and produces sustainability reporting standards. It was formed in 1997 and has released several versions of sustainability reporting guidelines. The GRI includes principles for defining report content and quality, as well as standard disclosures and performance indicators. While the GRI provides a framework for sustainability reporting, companies self-report and the GRI does not independently verify company activities. There is debate around whether sustainability reporting should be mandatory.
