Helping Residents Electrify Everything

LexCAN works closely with the Town of Lexington's sustainability team to create programs like Clean Heat Lexington.

Reducing Waste and Protecting Ecosystems

We work closely with many local partners like LexZeroWaste, Lexington Living Landscapes, and many more organizations for maximum impact.

Advocating for Policy Change

LexCAN has helped turn climate ideas into town bylaws — including the nation’s first gas-powered leaf blower ban and a law banning fossil fuels in new home construction. Advocacy isn’t just talk.
