Who We Are

Our Mission

We’re working to expand the use of alternative fuels, domestically-produced transportation fuels and energy-efficient vehicle technologies.  We’re a government/industry partnership, coordinated by the U.S. Department of Energy and administered by the Greater Portland Council of Governments.


Our coalition is comprised of fleet managers, business owners, clean fuel providers, state and local officials, and members of the public who want to reduce petroleum consumption and promote the use of clean fuels and clean fuel vehicles.


Our Services

Information and technical support on grant funding opportunities

Technical assistance for alternative fuel and anti-idling fleet transformation projects

Access to a network of local, regional, and national partners in the alternative fuel industry

Assistance for planning and promoting events

Educational activities focused on alternative fuels 

Become A Stakeholder

As a stakeholder, you’ll gain 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 gasses in the transportation sector. We report our stakeholder's alternative fuel usage to the US Department of Energy to help identify trends and greenhouse gas emissions savings.

Interested in becoming a Maine Clean Communities stakeholder? Please submit the stakeholder agreement form for your organization and we will get in touch!
