Pennsylvania Chapter

Welcome to the Sierra Club’s Pennsylvania Chapter! We are the only member-led statewide environmental organization in Pennsylvania and we believe our open spaces, clean water, and natural resources should be protected so that current and future generations may enjoy them. In addition to our offices in Pittsburgh, Harrisburg, and Philadelphia, we have nine active regional groups all across the state that help us explore, enjoy, and protect our state's many environmental resources and fight for safe and livable communities. Explore our site to see recent action alerts, read the latest blogs, and learn how you can get involved.
