Around 100 sustainability leaders from businesses, government and the public sector gathered together at Somerset House in London on Tuesday 29 April for the Carbon Trust’s annual Chairman’s Dinner.

Guests were welcomed by the Carbon Trust’s Chairman James Smith, before hearing from the keynote speaker Sir David King, the UK’s Special Representative for Climate Change and Chair of the Future Cities Catapult.

Following Sir David’s speech a three-course vegetarian meal was served and there was an opportunity for questions to be asked on a number of topics, including making international climate agreements.
