David Bent
Trustee and Chair of the Board

David Bent is passionate about playing his part in a generation that puts the world on a sustainable footing. David has worked at Forum for the Future, an independent non-profit working globally to solve complex sustainability challenges, for the last 13 years, most recently as Director of Sustainable Business. He advised dozens of companies in the UK, USA and India on strategy and innovation so they can be more successful by creating a sustainable future.

His perspective is that we need to shift so our global natural and social systems are coping (rather than overwhelmed, as they are now), and also people have access to what they need to choose their own lives. David supports institutions that are acting as a global ‘innovation function’, whether as an advisor, an executive, or a social entrepreneur. He recently finished advising the Cabinet Office on inclusive economy. His current priorities include: researching a pro-sustainability industrial strategy as an Associate Fellow of the Centre for Science and Policy, University of Cambridge; and, starting a ‘Gigatonne Lab’ to accelerate a rapid transition to a zero carbon world.

David has a Masters in Physics from Oxford, a Masters in Responsibility and Business Practice from Bath and is a qualified accountant, having spent 4 years at PricewaterhouseCoopers (PwC). He has been a tutor on the Post-Graduate Certificate in Sustainable Business at the Cambridge Institute for Sustainability Leadership.
