The Global Reporting Initiative (GRI) produces a comprehensive Sustainability Reporting Framework that is widely used around the world to enable greater organizational transparency.
There are over 100 countries communicating the impact of business on critical sustainability issues with GRI.
By using the GRI framework in conjunction with the ISO 26000 guidance, reporters will have a practical set of tools to measure and report on their social responsibility issues and practices.
