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.

Ever wonder what really happens when world leaders gather to fight climate change?

Join LexCAN and climate advocates from across our community for an insider’s look at COP30—the massive global summit where nations negotiate our planet’s future. This is where the Paris Accord was born, where breakthrough deals are struck, and where the fate of climate action hangs in the balance.

While we’re making strides here in Lexington and Massachusetts, the climate crisis demands worldwide cooperation, innovative solutions, and unprecedented financing. That’s where COP comes in—and this year, we had a front-row seat.

Ricki Pappo, Chair of LexCAN, spent two weeks immersed in COP30 as a League of Women Voters Observer—first virtually, then on the ground in Belém, Brazil, in the heart of the Amazon.

Ricki will take you behind the scenes with stories, photos, and insights into:

– The high-stakes negotiations that shape global climate policy

– The voices demanding action—from Indigenous leaders to youth activists

– The barriers we face and the solutions gaining momentum

– What it all means for climate action in our own backyard

This is your chance to understand how global climate decisions connect to the work we do right here. Bring your questions, your curiosity, and your commitment to making a difference.

The climate crisis is global. The solutions must be too. Let’s explore what that really means—together.
