In this episode of the Future of Finance, host Georges Dyer speaks with Temple Fennell, Co-founder and Managing Director of Clean Energy Ventures, to explore the frontier of climate tech venture capital. Temple shares how his fund backs early-stage companies targeting the most difficult sectors to decarbonize—concrete, ammonia, cooling systems, battery recycling, and more—with the bold goal of mitigating 2.5 gigatons of CO₂ by 2050. The conversation covers Clean Energy Ventures’ investment strategy, impact measurement through a proprietary emissions calculator, the intersection of technical rigor and scalable innovation, and the role of strategic partnerships in growing climate solutions. Temple also delves into the importance of policy-agnostic business models, underappreciated sectors like cooling and water, and his work supporting family offices and next-generation investors. This is a candid and in-depth look at how venture capital is fueling the clean energy transition.
