The Enel Endowment for Environmental Economics at Harvard University provides major support for HEEP. The Endowment was established in February 2007 by a generous capital gift from Enel SpA, a progressive Italian corporation involved in energy production worldwide. HEEP receives additional support from the affiliated Enel Foundation.

HEEP enjoys an institutional home in and support from the Mossavar-Rahmani Center for Business and Government at the Harvard Kennedy School. HEEP collaborates closely with the Harvard University Center for the Environment (HUCE). The Center has provided generous material support, and a number of HUCE’s Environmental Fellows and Visiting Scholars have made intellectual contributions to HEEP.

HEEP and the closely-affiliated Harvard Project on Climate Agreements are grateful for additional support from the Harvard University Climate Change Solutions Fund, the Harvard Global Institute, the Belfer Center for Science and International Affairs at Harvard Kennedy School, BP, Shell, and Christopher P. Kaneb (Harvard AB 1990).
