The Sierra Club is America's oldest, largest, and most influential grassroots environmental organization.

The Club promotes conservation by influencing public policy through grassroots activism, public education, lobbying, and litigation. We work to defend the environment at all levels of government including U.S. Congress, state legislatures, and state and federal courts.

Our Mission

Explore, enjoy and protect the wild places of the earth. Practice and promote the responsible use of the earth's ecosystems and resources. Educate and enlist humanity to protect and restore the quality of the natural and human environment. Use all lawful means to carry out these objectives.

In 1983 the Chapter opened an office in Harrisburg to conduct chapter business operations and lobby state legislators on environmental policies. The office houses Chapter Director, Jeff Schmidt, and Administrative Assistant, Carli Timpson, who perform a variety of lobbying, member service, and administrative functions. In addition, the office regularly hosts an intern.

In 2004 the national Club opened Field offices in Pittsburgh and Philadelphia. Headed by Rachel Martin, the national staff members work on the Building Environmental Community program, the Blue Green Alliance, Sierra Student Coalition, and other national priority programs and campaigns.

Our executive committee (ExCom)

The Chapter ExCom is composed of three delegates from the Southeastern Group, two from the Allegheny Group, and one from each of the other groups. Additionally, six At-Large Delegates are elected by the general membership for two year terms on alternating years. The excom elects its own officers, including the Conservation Chair, who appoints the 14 Conservation Issue Chairs, each focusing on a specific conservation topic such as air quality, public lands, or water quality.

The Chapter ExCom focuses on three primary areas:

Conservation: The Chapter Conservation Committee allocates staff time and financial resources for about six of the many issues that come up each year. The choice is determined by a variety of factors, including bills that are pending in the legislature, precedent-setting cases, or strong support from Sierra Club members.

Politics: The excom discusses political campaigns and issues, and determines which candidates to endorse and holding elected officials accountable.

Organizational development: The excom oversees the operation of the Club’s Harrisburg office, identifies new leaders, and provides them with mentoring and training.

The ExCom meets six times a year, including at the annual family retreat weekend. Excom meetings, like national meetings, are open to all members. Although members can’t vote, they can voice their opinions.

See our Chapter Directory for contact information for our Chapter and Group excom members and other volunteer leaders, as well as for our state's National and Chapter offices.

Internship Opportunities

Although internships in the Sierra Club’s Harrisburg office are unpaid, students participating in the program have the opportunity to learn more about the legislative process, assist in lobbying efforts to influence legislators and other decision makers, strategize with environmental leaders, take part in press conferences, and help out with a variety of activities that support grassroots advocacy, including preparation of mailings, database management, volunteer recruitment, and environmental issue research.

See Our Groups above to access a Group's website or to send an email to the Group's Outings chair for more information.

All participants on Sierra Club outings are required to sign a standard liability waiver. If you would like to read the liability waiver before you chose to participate on an outing, please go to individual liability waiver.

Outing leaders, please download, print out, and have all participants sign the sign-in waiver sheet. We also suggest you print out and bring extra copies of the individual liability waiver sheets. The individual liability waiver covers all events, so once an individual has signed this waiver, they do not need to sign it again for other outings.

The Environmental Law Program's docket covers the entire range of environmental issues, from local fights over ill-planned sprawl to cases of national significance on clean air, clean water and wilderness.


Sierra Club Foundation

The Sierra Club Foundation is a public charity whose mission is to provide financial support to the Sierra Club and other environmental organizations for tax deductible work. It funds a range of environmental projects which fall into the three general categories of public education, litigation, and training.
