Gabrielle Walker's Biography

Dr. Gabrielle Walker is an expert strategist, speaker and moderator, helping businesses to address global challenges—with a focus on sustainability, new energy and climate change.

Gabrielle 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.  Her recent TED talk is ‘What you need to know about carbon removal’ (2021) – with 2 million views so far.

She is the Founder of Valence Solutions and works with a team with decades of corporate expertise and deep personal commitment to accelerating action on the climate crisis. Using innovative meeting design, they provide a safe space for fresh conversations across perceived divides, thus developing a wider set of practical solutions to help tackle the most difficult and least addressed climate challenges. Through its partnership with the UNFCCC High Level Champions for Climate Action, Valence Solutions participated in many COP26 events in Glasgow.

Gabrielle has given 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. She 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”.

Gabrielle has a PhD from Cambridge University and has taught at both Cambridge and Princeton.

Gabrielle’s work has seen her make over a dozen trips to both North and South poles. She has also climbed trees in the Amazon, been sneezed on by a whale, extracted lava from an active volcano, swum amongst piranhas, and experienced zero gravity.
