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.

Coming Up

LexCAN Climate Book Club: Here Comes the Sun by Bill McKibben

January 24th 2026 | 7:00 pm - 8:30 pm

From the acclaimed environmentalist, Bill McKibben, a call to harness the power of the sun and rewrite our scientific, economic, and political future.

Our climate, and our democracy, are melting down. But Bill McKibben, one of the first to sound the alarm about the climate crisis, insists the moment is also full of possibility. Energy from the sun and wind is suddenly the cheapest power on the planet and growing faster than any energy source in history—if we can keep accelerating the pace, we have a chance.

Stay tuned to register for the Climate Book Club in January.
