Our Mission

The Sierra Club is a national environmental organization founded in California in 1892 by naturalist and explorer John Muir

The Atlantic Chapter is responsible for the Sierra Club’s membership and activities in New York State, and deals with a variety of environmental issues in the state, related to land use and development, pollution, energy, recycling, and endangered species and habitat protection. First formed in 1950, the Atlantic Chapter originally spanned the entire eastern seaboard, but a number of state organizations were formed in the 1960s and early 1970s, and, from 1972 on, the name “Atlantic Chapter” was restricted to just New York.
