The Greater Portland Sustainability Council was founded in 2012 to serve as a connector, clearinghouse, and catalyst for individuals and organizations working on environmental sustainability. Our activities have been growing steadily and we are in the process of expanding our scope statewide.


In September 2017 we held our fourth annual Portland Greenfest, drawing over 5,000 attendees to Monument Square in downtown Portland for over 60 exhibitors, music, art, local food and kids activities. Our exhibitors are the heart of the festival and include businesses and nonprofits working in the areas of clean energy, water quality, land conservation, green buildings, green products, sustainable transportation and similar focus areas. We are exploring the possibility of holding similar events in conjunction with existing major festivals in Maine to educate an even broader audience about sustainability.    

Our Home Energy Fairs have completed their fourth full year with fairs in Waterville, Auburn, Brunswick, Saco, Portland, South Portland, Gorham, Naples and Falmouth. Each fair draws several hundred home and business owners to learn from over 20 exhibitors about clean energy and energy efficiency options. 


Our Portland Regional Energy Working Group is made up of businesses, municipalities, and nonprofits. The group is beginning the process of developing a Clean Energy Action Plan for the Portland region, which we hope will serve as a model for other regions of Maine. We are also exploring the development of a “carbon-neutral Maine” campaign to make Maine the first carbon-neutral state in the nation.   


We co-coordinate the newly formed Maine Energy Work Group, a statewide effort launched a year ago by the New England Grassroots Environment Fund.


We serve as the parent organization for the Maine Environmental Sustainability Network a growing network of sustainability professionals affiliated with public institutions, non-profits, government entities and corporations, as well as community leaders, businesspeople and local residents, which meets regularly to foster collaboration, learning, and support for each other’s work. The network is open to anyone interested in environmental sustainability. The group’s sessions typically draw 30 – 60 attendees and include time for networking, one or more speakers on sustainability topics, and roundtable discussions. 


Other projects in the works are a Green Teams Alliance to support K-12 and college student green teams, a Green Business Council, and a Green Real Estate & Development Working Group.
