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

Climate Book Club: Doughnut Economics

June 8th 2026 | 7:00 pm

Have you ever wondered if there is something flawed in our current thinking about our economy, our health, and the health of our environment? If so, you may be interested in joining LexCAN’s next Climate Book Club as we read “Doughnut Economics: 7 Ways to think like a 21st Century Economist” by Kate Raworth. Registration link to come.

An economist redefines economics for a world in crisis in this “brilliant, thrilling, and revolutionary” book that champions a more sustainable way forward—and sparked a global movement (Guardian).

What if it were possible to live well without trashing the planet? Doughnut Economics succinctly captures this tantalizing possibility and takes up its challenge – Tim Jackson, Author of Prosperity without Growth
