Thinking Globally, Working Locally

What are local climate leaders saying about LexCAN? “LexCAN is one of those gems across the U.S., a committed and skilled group of people figuring out how to use their skills and their location to advance the climate fight in important ways!” Bill McKibben, Author, Activist, Educator, Middlebury College   “Changes at the federal level notwithstanding, LexCAN and its allies stay strong because the roots of the climate movement are so deep and healthy. LexCAN needs funding to stay this way. If you can, lend a hand.” Massachusetts State Senator Mike Barrett   “As the federal government withdraws from addressing climate change, it is more vital than ever for local communities to step into the breach. LexCAN is a wonderful example of how people in towns and villages can organize to spark meaningful action on climate change.” Kerry Emanuel, MIT Professor of Atmospheric Science (emeritus)     “From Cary Hall to the State House, LexCAN makes their voice heard and, as a result, is an invaluable group to our community and beyond. Lexington is lucky to have such a dedicated group of volunteers, working tirelessly to educate our community, advocate for a better future, and connect neighbors through shared action.” Maggie Peard, Sustainability & Resilience Officer, Town of Lexington

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.

LexCAN’s Climate Cafe

October 14th 2025 | 7:00 pm - 8:30 pm

You are invited to an informal Climate Cafe.

Let’s get together to chat and take action on climate change. Come and tell your story, share resources and find inspiration. We can explore project Drawdown’s Climate SHIFT (Super High impact Initiative for Fixing Tomorrow) and simply talk about what we are all thinking about and working on. Tea, decaf and snacks will be served. Fran Ludwig will also speak to us about what she heard at the conference in Rome: “Raising Hope for Climate Justice’, commemorating the 10th anniversary of Laudato Si'”. Fran was invited to attend this conference of luminaries in the field.
