The Rockefeller Foundation, established in 1913 by Standard Oil tycoon John D. Rockefeller, announced today that it aims to make its $6 billion endowment net zero emissions by 2050. That makes it the largest private foundation in the US with such a target.

Rockefeller follows a number of other US institutions, including Harvard University, which pledged in 2020 to get its $50 billion-plus endowment to net zero on the same timeline.
