Energy and Water Benchmarking

All South Portland buildings 20,000 square feet or larger are required to report their energy and water usage annually. Information for the 2022 reporting year has been posted. Please visit our Benchmarking page for information on how to comply.



The mission of South Portland's Office of Sustainability is to guide the development of policies and practices that simultaneously promote economic well-being, strong community connections, and a healthy environment. The Sustainability Office works directly with all municipal departments, the City's Waste Reduction Committee, the Landcare Management Advisory Committee, and numerous community partners to achieve its mission. 


Climate Goals

The City of South Portland committed to ambitious climate goals that guide the work of the Sustainability Office: 

  1. Reduce community-wide greenhouse gas emissions 80% from 2017 baseline levels by 2050.
  2. Transition to 100% clean renewable energy in municipal operations by 2040.
  3. Build the resilience of our neighborhoods, infrastructure, and ecosystems to prepare for, withstand, and recover from the impacts of climate change.

The Cities of Portland and South Portland developed a joint climate action & adaptation plan that charts a course to meeting these shared goals. One Climate Future is an innovative regional approach that lays out the steps to achieving aggressive carbon reduction goals, growing a circular economy, building community resilience, and creating more just and equitable cities. The South Portland City Council officially adopted the plan on October 13, 2020.
