Grantham Foundation

Grantham Foundation for the Protection of the Environment is a philanthropic organization based in Boston, Massachusetts, providing grants to initiatives focused on climate change, biodiversity conservation, and environmental research globally. The foundation supports a wide range of grantees, including academic institutions like Imperial College London's Grantham Institute and environmental reporting organizations, with a particular emphasis on global environmental groups. Founders Jeremy and Hannelore Grantham committed 98% of their approximately $1 billion fortune to climate action in 2019, underscoring their dedication as Giving Pledge signatories. This commitment builds on Jeremy Grantham's background as co-founder of GMO, an investment firm that managed $118 billion AUM in 2015.
