Climate philanthropies are playing an increasingly important role in funding climate action. In 2023, an estimated $9-16 billion was spent by philanthropies on programs to mitigate climate change. But how do they choose how to spend it? And what role should philanthropy play in catalysing innovation?

Bryony Worthington sits down with Greg de Temmerman, Deputy CEO of the Quadrature Climate Foundation, to explore these critical questions. As a former plasma physicist who worked on the world's largest nuclear fusion project before transitioning into philanthropy, Greg brings a unique perspective to the climate challenge.

Greg shares his insights on the progress and challenges in fusion research, highlighting the importance of material science breakthroughs and the role of AI in advancing the field. He then discusses his transition from research to the think tank world, where he sought to provide a more science-based approach to climate solutions and address the growing anti-tech sentiment in France.

The conversation delves into Quadrature's evidence-based, pragmatic approach to philanthropy, and Greg's views on the foundation's support for geoengineering research and carbon removal technologies. He emphasises the need to grapple with the complexities of the energy transition, including the social and political challenges of managing winners and losers, and explains why he thinks the climate fight is like ultra-running.
