Our startups

Eight innovative carbon emissions-mitigating startups have been launched so far by Carbon13’s Venture Builder for the Climate Emergency and have received a total investment of £1 million plus in-kind support to fast track their development into highly scalable Net Zero ventures.

Each startup that you see on this page has the potential to reduce CO₂e emissions by at least 10 million tonnes per annum. 

Our ventures

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 three of the ventures are led by female CEOs and four have minority ethnic leaders (including three CEOs.)

This list is about to get longer

Our second cohort began their journey in September 2021 and we’ll be announcing the recipients of our investment soon.

And, if you want to add a startup to this list and become a founder of a high growth startup capable of reducing emissions by 10 million tonnes per year, then applications are now open for our third cohort which will begin in April 2022.
