Citywide Climate Action & Adaptation Plan

The City of South Portland is partnering with Portland to develop a regional vision for reducing greenhouse gas emissions and improving the resiliency of our communities. 

Both cities have adopted aggressive climate goals:to transition municipal operations to 100% clean renewable energy by 2040, and to reduce community wide greenhouse gas (GHG) emissions 80% by 2050. Given the alignment of our goals and our close proximity, we have chosen to collaborate on the development of a Climate Action and Adaption Plan. We will be developing one plan with concrete, measurable actions to move toward tour goals. Producing one plan will emphasize the joint nature of the planning process, and will better exemplify a new model for cities working together to address climate change.  

The plan will be developed through a stakeholder process that will engage individuals, community groups, and local businesses, and draw on the expertise of recognized regional leaders. Equally important as the actions it identifies, the plan is intended to mobilize community engagement and build support for climate action.


The Climate Action and Adaptation Plan will be structured around four focus areas: 1) energy and high performing buildings, 2) transportation and land use, 3) waste reduction, and 4) climate preparedness. Centered on these sectors, the plan will:

  • Provide strategies to transition each community from fossil fuels to clean renewable energy to achieve an 80% reduction in community wide GHG emissions by 2050;
  • Suggest opportunities to reduce overall energy consumption through energy efficiency and conservation measures;
  • Recommend a path to transition to a near zero-waste economy that prioritizes waste reduction and reuse of resources;
  • Prepare each city for anticipated impacts of climate change including, but not limited to, rising sea levels, more frequent significant rain events, more powerful coastal storms, and more frequent days with heat over 90 degrees Fahrenheit;
  • Identify policy opportunities at the state, regional, and federal levels that may help reduce emission sources not controlled directly by the City; 
  • Ensure that recommended actions incorporate the needs of all members of the community in order to create equitable outcomes; 
  • Serve as a mechanism to tie together each city’s existing and developing sustainability initiatives and plans with established community goals;
  • Define metrics for measuring progress, lowering community-wide greenhouse emissions, and engaging residents, businesses and community groups;
  • Position the cities to maintain a high quality of life with livable neighborhoods and a strong business environment; and,
  • Facilitate to mobilize broad community action around climate change.
