I highly recommend Gwen White as a GRI Standards trainer. She has an in-depth knowledge of the Standards, their predecessors (G3 & G4), and the best practices for their adoption. Her passion for sustainability reporting and her 30 years of experience as an educator shine through in her teaching. I’ve had the pleasure of attending both the GRI Certified Training Course based on G4 Reporting Guidelines and the Transition to GRI Standards course taught by Gwen. Both were very engaging courses with practical application exercises and I felt confident in the knowledge gained from them. During the trainings I really enjoyed how she always provided real world corporate examples to illustrate how best to apply a principle or tool. After I completed the class while preparing for the exam, she was always very responsive to additional questions I had about the material.

Learning CDP and GRI metrics are part of being competitive as a consultant in Sustainable Development now.  Its hard to make learning standards of verified social and environmental performance, public transparency, and legal accountability dynamic — But Gwen made the sessions interactive and ran us through case-study scenarios.  Well worth the investment and time to take the course through the ISOS group, hopefully you will get Gwen as your instructor!
