Investment thesis

Lowercarbon Capital backs profit-driven companies applying hard science and ambitious engineering to fight climate change. Its investment focus spans three areas: cutting new CO2, methane, and other greenhouse gas emissions across energy, transportation, industrial materials, and agriculture; removing existing atmospheric carbon at large scale; and developing technologies to cool the planet and buy more time against worsening climate impacts. The firm views decarbonization as a strong business opportunity driven by markets rather than guilt, and emphasizes hands-on support for founders from a company's inception through national product launches, backed by an ecosystem of founders and industry experts.
