Auction Proceeds

Based on the Green Communities Act of 2008, the Department of Energy Resources (DOER) has directed the vast majority of the Commonwealth’s RGGI proceeds into the state’s nation-leading energy efficiency programs delivered statewide by the state’s utilities and energy efficiency service providers through Mass Save®, and the Green Communities Designation and Grant Program for cities and towns. These programs and initiatives are fueling a cleaner energy future for the Commonwealth.

Massachusetts has received $776,189,135.81 since 2008.
