Billion Dollar Green Challenge

The Billion Dollar Green Challenge initiative advocates for the efficacy of green revolving funds (GRFs), and works to increase the number and size of self-managed green revolving funds at nonprofit institutions across the United States.

The Challenge provides support for new and established  green revolving funds at colleges and universities. A GRF is a financing mechanism targeted to campus climate action projects that lower emissions, increase capacity for future projects, and reduce operating costs.

The Billion Dollar Green Challenge was founded by the Sustainable Endowments Institute in 2011. Second Nature oversees and manages US colleges and universities within the initiative. Learn more.
