GRI guidelines
Global Reporting Initiative (GRI)
Established in 1997 as a joint project between the Coalition for Environmentally Responsible Economics (CERES), a nonprofit organization in the United States, and the United Nations Environment Programme (UNEP), the GRI aims to improve the contents of sustainability reports to the level of financial reports while attaining the basic conditions of comparability, credibility, accuracy, appropriateness of timing, and verifiability of the information included in the sustainability reports. The initial guidelines were issued in 2000, then revised in fiscal years 2002, 2006 and 2013. In fiscal 2016, new guidelines were issued as the GRI standard.
