Contribute to the Sierra Club

We can’t do this work without the help of our volunteers—and through the support of members like you. Conservation efforts depend on your support. Every dollar you donate stays here in Connecticut to continue to protect rivers, forests, and wildlife that depend on us. Please consider a donation to Sierra Club's Connecticut Chapter so we can continue to fight for cleaner air, cleaner energy, and more wild places.

Gift Planning

Planning an estate gift to Sierra Club’s Connecticut Chapter is an affordable way to sustain our environment for decades to come and to inspire the next generation of activists like you. Making a gift to the Connecticut Chapter may be easier than you think.

Donate Your Car

Did you know you can donate your vehicle and support the charitable programs of Sierra Club Connecticut? We make it easy for you to donate your vehicle. Whether it's running or not, your car, truck, boat, RV, or motorcycle will support Sierra Club Connecticut, sponsored by the Sierra Club Foundation.

Climate Ride

Since its founding in 2008, thousands of bicycle riders have powered the Climate Ride on their quest to protect our planet and improve lives through sustainability and active transportation.  During this decade, participants have raised millions of dollars to donate to environmentally oriented organizations. And since 2017 Connecticut Chapter Sierra Club has been officially designated as a Climate Ride beneficiary.

Pedaling for Connecticut
Support us by joining a Climate Ride, Hike, or Run! We are a Climate Ride Beneficiary which means you can have the trip of a lifetime while doing good for our planet and supporting our work! Climate Ride will help you FUNdraise and reach out to your friends and family about important issues.

Your support in this time of crisis will keep our important mission going. Help our chapter by fundraising, by spreading the word about our important work, or both!

HOW: Go to and register for your event! Once you register, you'll get a fundraising page and an email from a real person who will help you with anything you need!


Couch Support
If spending a couple of days on a bike or out in the woods isn't your thing, you still have another option to support our Chapter through the Climate Ride. Our Chapter Communications Chair, Dennis Desmarais, has signed up for his 11th Climate Ride. Once again he'll be doing what is called an Independent Challenge (rather than one of the organized events). Please pedal with him in tandem or in spirit and support his ride as he fiercely works to help support our chapter. Please consider making a tax deductible donation here

Dennis Desmarais is the Communications Chair, CT Chapter Sierra Club.
