I just received my GRI G3 reporting certification from the course I took last week.  The course was delivered in Colorado for the first time due to the efforts of CORE with support from Deloitte.  Lead, out of Canada, provided the training based on materials from the Global Reporting Initiative.

The instructor was well informed, as were the 26 attendees. Lively discussion, along with some good and some not so good exercises provided us all with a great understanding of the G3 framework and the processes companies should put in place to engage stakeholders, prioritize initiatives, disclose results, share goals and increase sustainability through management processes and transparency.

Global Reporting Initiative
The Sustainability Reporting Framework – of which the Sustainability Reporting Guidelines are the cornerstone – provides guidance for organizations to disclose their sustainability performance. It is applicable to organizations of any size or type, and from any sector or geographic region, and has been used by thousands of organizations worldwide as the basis for their sustainability reporting.
