Who We Are
The Clean Cities and Communities partnership is a national network of local coalitions hosted by the U.S. Department of Energy. Maine Clean Communities is the state coalition, administered by the Greater Portland Council of Governments (GPCOG).

The goal of the Clean Cities and Communities coalitions is to strengthen the nation's environment, energy security, and economic prosperity by working locally to advance affordable, reliable, and secure transportation fuels and technologies.
Maine Clean Communities works with vehicle fleets, fuel providers, community leaders, and other stakeholders to identify community-driven choices that save energy and promote the use of alternative fuels and advanced vehicle technologies in transportation.
Join the Coalition
Members enjoy full access to our services and make connections with people, businesses, and organizations in our statewide network. Once a year, we'll check in and ask you to fill out a survey on your progress towards transitioning to alternative fuels and reducing greenhouse gases in the transportation sector. We report our partners' alternative fuel usage to the US Department of Energy to help identify trends and greenhouse gas emissions savings.
