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.
