Our Team


Global Action Plan is jointly led by Sonja and Chris, both long time GAPpers with a shared passion for our natural world.

Sonja Graham, Co-CEO


Sonja’s aim in life is to show that the sustainable choice is the better choice, rather than the "green" one. With a background in psychology, she specialises in the design of behaviour-change programmes that reduce environmental impact. Intent on closing the gap between research and practice, Sonja founded a Behaviour Change working group with four universities (The Real-World Sustainability Research Team) and has authored papers on motivating environmental behaviour. Follow Sonja @Sonja_tweets


Chris Large, Co-CEO


Chris has been leading programmes such as the multi award-winning Operation TLC since he joined Global Action Plan in 2005. Chris's achievements include directing staff engagement programmes for three of the big six energy suppliers in the UK, and training pan-European climate leaders and environment officers to become environmental advocates. He has also written environmental policies and roadmaps for clients such as corporations and NHS trusts, and informs policy through consultation responses and conference presentations. Follow Chris @ChrisLarge1
