Carmichael Roberts — Breakthrough Energy Ventures — Climate

**Carmichael Roberts** is a co-lead of **Breakthrough Energy Ventures (BEV)**, the $2B+ climate technology fund created by Bill Gates and supported by Jeff Bezos, Jack Ma, Richard Branson, and other billionaires. A former serial entrepreneur and materials scientist (PhD MIT), he spent 20 years building and scaling hard-science companies before joining BEV. He evaluates climate technology with both deep scientific understanding and commercial scaling experience.\n\nBEV's investment thesis is rigorous: technologies must have the potential to reduce greenhouse gas emissions by at least 500 million tons of CO2 equivalent per year — approximately 1% of global emissions. This 'gigaton test' eliminates most climate technologies.
