Our mission is to explore, enjoy, and protect the wild places of the earth; to practice and promote the responsible use of the earth's ecosystems and resources; to educate and enlist humanity to protect and restore the quality of the natural human environment; and to use all lawful means to carry out these objectives.
The Pennsylvania Chapter was started in the early 1970s and officially opened its office doors in Harrisburg in 1983. With over 25,000 members, we are led by an all-volunteer executive committee that shapes the conservation, political, and organizational work of the Chapter as it seeks to reach the objectives of the Sierra Club mission.
