Maine Clean Communities


The Maine Clean Communities (MC2) Coalition is a locally based government/industry partnership, coordinated by the U.S. Department of Energy and administered by the Greater Portland Council of Governments (GPCOG). 

Our mission is to expand the use of alternative fuels to gasoline and diesel fuel, advance affordable domestically-produced transportation fuels, and promote energy-efficient vehicle technologies.


Funding for Maine Clean Communities projects and events is provided by the U.S. Department of Energy, PACTS, and GPCOG.

Adopting Solutions

Maine Clean Communities was formally designated as a statewide U.S. Department of Energy's Clean Cities program coalition in 1997, and is one of nearly 100 coalitions around the country. It has been a central piece of GPCOG's work for two decades, resulting in transit agencies switching to cleaner fuels, adoption of electric vehicles (EVs) into municipal fleets, and reduction of pollution and reliance on oil.


The coalition is administered by GPCOG, and comprised of fleet managers, state and local officials, clean fuel providers, and other groups and individuals. It achieves measurable savings in transportation fuel use and emissions through a combination of technical assistance, education, outreach, and one-on-one support to fleets. In 2018 alone, Maine saved the equivalent of over 2.2 million gallons of gasoline and 14,000 tons of greenhouse gases.
