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 global energy corporation. Read about the gift in the Harvard Gazette. HEEP receives additional support from the affiliated Enel Foundation.

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

HEEP enjoys an institutional home in and support from the
Mossavar-Rahmani Center for Business and Government at Harvard Kennedy School. As its name suggests, the Center is concerned with the interaction of the public and private sectors, including with regard to environmental issues.

HEEP—along with many other Harvard organizations and individuals concerned with the environment—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.
