Gabrielle is an expert strategist, speaker and writer, helping businesses to address global challenges with a focus on sustainability and climate change. She is a TED speaker and has a strong background in building new narratives and engagement across a wide range of sectors. She works at boardroom-level with a broad set of global companies to analyse emerging global trends, challenge conventional thinking and turn analysis into meaningful action. 

Gabrielle is co-founder of two organisations aiming to accelerate action in the confused but vital area of carbon removals and figure out how to do them right: non-profit Rethinking Removals (working in partnership with the UNFCCC Climate Champions) and for-profit CUR8.

Gabrielle gives keynote addresses to corporate audiences around the world and is an accomplished moderator of high-level debates, guiding panels involving global CEOs, former heads of state, government ministers, military generals and global humanitarian leaders. She has presented many TV and radio programs for the BBC. She has been Climate Change Editor at Nature and Features Editor at New Scientist and has written extensively for many international newspapers and magazines, including The Economist, Prospect, The Wall Street Journal and The New York Times.

Gabrielle is author of four books including co-authoring the bestselling book The Hot Topic, how to avoid global warming while still keeping the lights on, which was described by Al Gore as “a beacon of clarity” and by The Times as “a material gain for the axis of good”. She has a PhD from Cambridge University and has taught at both Cambridge and Princeton.

A self-confessed “ice addict” Gabrielle has made more than a dozen trips to both poles. She has also climbed trees in the Amazon rainforest, swum with piranhas, been sneezed on by a humpback whale, hooked lava out of a live volcano, and flown in zero gravity.
