The Global Reporting Initiative (GRI) says record amount of feedback received from sustainability experts, organizations and professionals on the next generation of the GRI's Sustainability Reporting Guidelines reflect a growing interest worldwide in sustainability reporting. GRI produces a comprehensive sustainability reporting framework that is widely used around the world. GRI is now working on the next generation of its Sustainability Reporting Guidelines – G4. As part of the development process, GRI held two Public Comment Periods (PCPs). The first, held from August to November 2011, aimed to gather opinions on sustainability reporting, through an online survey. The second PCP, open from June to September 2012, aimed to gather the public's feedback on the G4 Exposure Draft, to ensure the Guidelines are relevant and useful for all organizations worldwide. The GRI received 3,095 submissions during two comment periods.
