The Grantham Foundation, founded by legendary British investor Jeremy Grantham and his wife Hannelore in 1998, committed 98% of their $1 billion fortune to climate action and environmental protection. The foundation invests in overlooked and underestimated early-stage climate solutions across 45 projects spanning ocean acidification, lithium extraction efficiency, and direct carbon capture. With major funding commitments to leading climate research institutes at Imperial College London, the London School of Economics, and University of Sheffield, the Grantham Foundation combines early-stage venture support with institutional climate research.
