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.

Trusted by local climate leaders

Bill McKibben, Senator Mike Barrett,  Kerry Emanuel, and Maggie Peard share their support for LexCAN

Coming Up

No Kings Protest in Boston and Lexington

March 28th 2026 | 10:00 am - 4:00 pm

All the major MA climate organizations are joining in an effort organized by the 350 Mass democracy and climate group to have identifiable climate contingents at as many MA No Kings events as possible.

The strategy is simple for Lexington: climate activists show up on the Muzzey St sidewalk by the public parking lot entrance at 9:45am on March 28th to receive green armbands. Each of us brings a sign relating climate to democracy like “Democracy is a dialogue; climate change is the deadline.” For ideas, see here.

We will then walk together the short distance to the Lexington protest at the Visitor Center starting at 10am. LexCAN will join the Brookhaven Residents Climate Change Committee.

See here for information on the Boston Rally.
