Sustainable Westchester is a nonprofit membership organization of Westchester County local governments that facilitates effective collaboration on sustainability issues. Our goal is to bring socially responsible, environmentally sound, and economically viable solutions that create healthy, resilient, and sustainable communities.

Formed from the merger of the Northern and Southern Westchester Energy Action consortia, Sustainable Westchester’s membership rapidly expanded to include the membership of all but one municipality in Westchester County and now serves more than 900,000 residents. The organization formulates effective responses to important sustainability-related opportunities, such as energy efficiency, renewable energy, zero waste, land use, clean transportation, and more.
