Lowercarbon Capital is a venture capital firm that invests in companies developing technologies to combat climate change through three primary approaches: slashing CO2 emissions, removing carbon from the atmosphere, and buying time to address planetary climate issues. They focus on backing what they call "kickass companies" that can make real money while addressing environmental challenges across sectors including energy, transportation, industrial materials, and agriculture.
The firm operates on the philosophy that fixing the planet is good business and that market forces, rather than shame and guilt, will drive the necessary climate solutions. They combine hard science with ambitious goals, seeking companies that can deliver better, faster, and cheaper alternatives to fossil fuel-based technologies.
Lowercarbon Capital plays a significant role in the climate tech ecosystem by funding innovative companies across diverse sectors from solar and wind energy storage to fusion technology, electric aviation, and carbon-free chemical production. Their portfolio includes companies like Antora, Commonwealth Fusion Systems, Heart Aerospace, and Solugen, positioning them as a key player in scaling climate solutions that can achieve commercial viability while delivering environmental impact.
Lowercarbon Capital invests in companies that tackle climate change through three core areas: reducing new CO2 emissions across energy, transportation, industrial materials and agriculture; developing carbon removal technologies to address existing atmospheric CO2; and creating solutions that buy time while longer-term fixes are developed. They seek companies that combine rigorous science with ambitious goals and can deliver commercially viable alternatives to fossil fuel-based technologies.
The firm focuses on companies that can generate real revenue while delivering environmental impact, operating under the belief that market-driven solutions rather than regulatory or moral pressure will ultimately scale climate technologies. They appear to invest across various stages and geographies, with a portfolio that spans from energy storage and fusion technology to sustainable aviation and bio-based chemicals.
