Decarbon8-US is a philanthropic impact fund. It uses donations and grants to invest in early stage companies whose technologies accelerate the transition to environmentally sustainable solutions.
Entrepreneurs apply in the spring and a team of selected investors, fellows, and experts choose 2-4 companies to receive funding in the fall. Each year the Decarbon8-US Fund choses a different theme around decarbonization.
All contributions to Decarbon8-US are tax-deductible and are made to our 501(c)(3) partner Realize Impact, who administers the Fund.
