The Sierra Club, a non-profit organization, is the nation’s longest standing volunteer driven environmental organization. Its purpose is to ‘explore, enjoy and protect the planet’. It does this by educating the public and influencing public policy decisions — legislative, legal, and electoral.


Please note that donations and dues for these policy efforts need to meet specific standards to be tax deductible. Donations to the Sierra Club Foundation are 501c3 tax deductible. Locally the Sierra Club Long Island Group is advocating for climate change resilient strategies with the legal Article 78 case for the Hempstead Lake State Park project within the Mill River Watershed.
