Since our founding in 2005 based in Harvard Square, the Sustainable Endowments Institute (SEI) has pioneered research, education and platforms to advance resilient institutional leadership on climate and energy. SEI has a 16-year track record of achieving game-changing impact. As Bill McKibben commented at our 10th anniversary celebration: "There is no institution that's done more to help in the last decade than Sustainable Endowments...it's really powerful. Thank you for showing that nice guys get things done in big ways."
