The climate crisis needs determined founders committed to this challenge, including scientists, engineers, and serial entrepreneurs. The average age of our cohorts is 37, and a third hold PhDs.
Every startup we build has the potential to reduce or remove CO₂e emissions by net 10 million tonnes per year when at scale.
Our community is rooted in our mission to fight the climate emergency, and driven by our scalability ethos. This is where climate tech startups will succeed on a global scale.
Our Cambridge origins have taught us the importance of commercial, carbon and scientific understanding. Our growth to Berlin fuels our ecosystem of domain expertise, investors, and partners.
We will select and support thousands of entrepreneurs to build ventures with the potential to mitigate over 400 million tonnes of CO2e per annum by 2040. We have set this target because humanity has just a few years to reduce our emissions and slow the pace of global warming, and the innovation delivered by entrepreneurs can play a significant role within this fight.
We simply don’t have time for founders to waste on dead ends or incremental solutions, or to build companies which don’t make a true impact on emissions. The future is Net Zero. Our startups are already building it.
Welcome to Carbon13’s podcast “Climate Takes” where we ask special guests for their “takes” on their industry and climate challenge, as well as setting a call to action, asking what will it take to solve the climate emergency?
Whether you’re already a founder or ready to become one, explore our programmes to see how we’ll work with you to innovate on solutions for the climate emergency.
Venture Builder Cambridge
An eight-month programme for a cohort of 80 determined individuals from the UK and beyond, who don’t have a startup yet but want to find a co-founder and build a climate-tech startup.
Venture Builder Berlin
For founders resident in the EU, our Berlin Venture Builder combines the entrepreneurial and academic spirit of Cambridge with the DACH climate tech scene.
Venture Launchpad
The Venture Launchpad is a fully remote startup accelerator where teams work on their Carbon Case, their growth strategies, and their investment readiness for pre-seed and beyond.

Materials Nexus is a deep-tech company originated at Cambridge University and Carbon13, who combine the insights of quantum mechanics with the power of AI to predict the properties of materials. Materials such as concrete, steel and glass contribute towards 50% of all CO₂ emissions. New, better materials are needed for a new, low carbon world – but it typically takes 20 years to develop a new material to be commercialised.
Their ground-breaking AI-enabled Materials Discovery Platform transforms the way new materials are designed using a rapid automated process and advanced quantum calculations that give high accuracy at larger scales.

3 billion tonnes of CO2e are emitted from methane in water each year. There is no way to remove this methane at scale. Until now. Bluemethane measures and removes methane from water. The methane is then used as a new source of clean energy. Their technology is scalable and can be deployed in a variety of settings, including wastewater treatment plants, reservoirs and rice cultivation. With methane’s global warming power 34x that of carbon, Bluemethane is tackling a core problem for global warming.
