John was the principal advisor on climate change at the RSPB and a lead member of the BirdLife International team on climate change. He attended all of the main international negotiating meetings on climate change since Rio in 1992, and worked extensively on EU climate and energy policy.

He delivered an important keynote on the progress in international climate negotiations at Medact’s 2016 conference, Healthy Planet Better World.

We were very saddened to hear of his passing in October 2018.
