Carbon13’s mission is to use entrepreneurship to reduce emissions by at least 400m tonnes per annum. It was founded with a belief that diversity in entrepreneurial founders is an important part of bringing the “think different” mindsets and perspectives to the fore which can achieve the kinds of breakthroughs required by the Net Zero challenge. It is notable therefore that 25 of the 44 ventures have female founders, and 16 have minority ethnic leaders. In Cohort 3 alone, 75% of the ventures have teams of more than one nationality, with founders from America, Asia, Europe and Africa. 

Want to add to this list?
