History
Environmental Action at Swarthmore
Swarthmore College has a long tradition of honoring the natural environment. As concern about climate change mounts here and around the world, the College continues to address the issue and make substantial strides in reducing its energy and water consumption.
1863
Location of Swarthmore College
"The Westdale property, Springfield Township, Delaware County, Pa. ... furnishing a fine building site upon high ground sloping to the south, and commanding a fine view of the surrounding country … no place offered to the Committee affords such romantic and secluded rambles as the rocky and sloping hill-sides which bound this stream [Crum Creek].” — Circular, Board of Managers, 1863
1869
Opening Day
Swarthmore’s Quaker founders “loved trees,” wrote John Wister, the first director of the Scott Arboretum, in 1939. “On the opening day, Nov. 10, 1869, Lucretia Mott planted a red oak; a succession of famous men and women, including presidents of our country, have planted trees on Founders Day ever since.”
1929
Scott Arboretum
The Scott Horticultural Foundation is founded on campus in honor of Arthur Hoyt Scott, Class of 1895. Today, the Scott Arboretum encompasses more than 300 acres of the Swarthmore campus and exhibits over 4,000 different kinds of plants recommended for area gardens.

1996
Environmental Racism Conference
Students organize a conference on environmental racism in Chester, Pa. that draws 60 students from 15 colleges and universities. Their efforts lead to the formation of the Campus Coalition Concerning Chester, which was active in the 1990s in that city's environmental justice efforts.
1999
Wind Power
Swarthmore begins purchasing Renewable Energy Credits (RECs) in the form of wind power. Since 2011, 100 percent of the College’s greenhouse-gas emissions generated as a result of electricity are offset by RECs.
2000
Crum Woods Stewardship
The College establishes a committee of students, faculty, and staff members to protect, restore, and steward the 220 acres of mostly forested land along the Crum Creek that straddles Swarthmore’s campus.
2003
Green Roofs
The College’s first green roof is installed on a shed behind Papazian Hall in 2003. The next year, Alice Paul Hall becomes the first residence hall in North America to have a green roof. David Kemp Hall joins in 2009.
2007
Green Power
Swarthmore and Earthlust, a student environmental activism group, receives the Green Power: Turn It On! Award from PennFuture for helping to start the College’s recycling program and raising awareness about food waste and electricity usage, among other campaigns.
Trash to Treasure
The first sale of gently used items donated by students at the end of the year raises more than $12,000 for nonprofit organizations in the community. The 2014 T2T sale raised approximately $20,000 and kept about 14 tons of material – picture 25 industrial-sized dumpsters – from being incinerated.
2008
Sustainability Committee
A committee of students, faculty, and staff members is formed to make recommendations to the President and to the College community regarding policies to promote environmental sustainability on campus.
Composting
Composting of food waste from the dining hall begins.
2010
Environmental Studies Senior Capstone
The 2010 Senior Capstone Seminar of the Environmental Studies creates a website to serve as a resource for many of the issues surrounding drilling of the Marcellus Shale.
Climate Commitment
President Rebecca Chopp signs the American College & University Presidents’ Climate Commitment, joining leaders of institutions in higher education across the country in accelerating educational and operational efforts to address climate change. The College has since taken several actions to fulfill this commitment, including the development and adoption of a Climate Action Plan.
2011
Investment Strategies
Members of Mountain Justice, a student group that works toward climate justice, the administration, and the Board of Managers meet to discuss the College’s endowment and the possibility of divesting the College from investments in fossil fuels. Discussions continue at dozens of meetings between 2011 and 2013.
2012
Greenhouse Gas Inventory Report
The College publishes the 2005-2010 Greenhouse Gas Inventory Report [pdf], which inventories greenhouse gas emissions and serves as the baseline assessment for Swarthmore’s Climate Action Plan.
Carbon Neutrality
To meet the Presidents' Climate Commitment, the College develops and adopts a Climate Action Plan [pdf], which pledges carbon neutrality by 2035.
2013
Decision on Divestment
Board Chair Gil Kemp ’72, on behalf of the Board of Managers, informs the community that “[I]t is our collective judgment that the cost of divestment would far outweigh any potential benefit. If we thought divestment would change the behavior of fossil fuel companies, or galvanize public officials to do something about climate change, or reduce America's reliance on fossil fuels, this would be a much tougher decision. We believe we have other, more effective means to achieve this objective.”
LPAC Green Roof
At 31,000 square feet, the completion of the LPAC’s green roof more than doubles the College’s total green roof acreage, which absorbs rainwater while also providing natural habitat.
U.N. Climate Change Conference
Swarthmore seeks and is granted NGO observer status to the United Nations Framework Convention on Climate Change Conference of the Parties and now sends students, staff, and faculty to the annual meetings of the U.N. body tasked with developing international agreements to stabilize greenhouse gas emissions and prevent climate change.
2014
Sustainability Director
The College hires its first sustainability director, whose early initiatives include administering the College’s Green Initiatives Fund, partnering with a car share program, and leading the development of sustainable building standards for renovations and new construction on campus.
Call for Big Ideas to Address Climate Change
Interim President Constance Hungerford issues a call for ways the College could address climate change; the community responds with more than 160 ideas.
REPORT TO THE PRESIDENT
The College's first sustainability director, Laura Cacho, issues a report [pdf] to the president that provides a snapshot of the College’s past and current practices and policies regarding environmental sustainability, some of the gaps in action, and the challenges the College faces to improve its environmental practices.
Note from the author: This report is intended to provide a snapshot of the College’s past and current practices and policies regarding environmental sustainability, some of the gaps in action, and the challenges the College faces to improve its environmental practices. It should serve as a working document that will be modified as I continue to serve as director of sustainability, and I plan for it to become the starting place for a community conversation on sustainability and all of our roles.
When I was hired in February, my directive was to focus a significant portion of my time on reducing the College’s carbon footprint and improving the College’s practices regarding environmental sustainability. As this report illustrates, the College has made great strides in these areas thanks to the work of numerous dedicated staff, faculty, and students; much of this work has been performed with volunteer labor or outside of employees’ regular job descriptions. However, the challenge of meeting the goals of carbon neutrality by 2035 and drastically improving our practices will require more than the devoted effort of a few people. It will require community members to self-monitor their behaviors and daily activities at the College, i.e., individual consumption of energy and water, types and quantities of materials purchased, modes of waste disposal, and frequency and means of travel. It will also require a significant investment in our infrastructure to eliminate use of fossil fuels for energy; the creation of a consistent and clear waste system across the entire campus so that good habits are easy to form; improved storm-water management practices to minimize the impacts of our current and future development; the capture and reuse of rain- and gray water to reduce the use of drinking water for non-potable purposes; and the development of standards and policies to guide our future actions.
These changes will not happen overnight, and they will require difficult, complex choices and creative thinking. I look forward to working with each of you as we take on this challenge as a community. I will be reaching out to each department in the coming year, but in the meantime, please feel free to contact me directly to start the conversation.
Commitment to Sustainable Buildings
The Board of Managers commits $12 million to making the planned biology, engineering, and psychology building project, now Maxine Frank Singer Hall, a model for environmentally intelligent construction practices.
Investment Survey
As part of its ongoing due diligence, Swarthmore asks its investment managers to describe their approach to climate change. Nearly all of the firms with whom the College has active relationships consider climate change in their investment process and dedicate significant resources to defining, measuring, analyzing, and improving the environmental impact of their investment decisions.
2015
Sustainability Charrette
On February 11th and 12th, The Board of Managers sponsors a Sustainability Charrette that generated proposals in six critical areas for the College community’s consideration and action, including improving the College’s energy efficiency, installing a renewable energy system on campus, evaluating how the College’s endowment is invested, and becoming a zero-waste campus.
This unique event combined inspiring and thought-provoking talks from leaders in sustainable design, engineering, policy, and economics with a collaborative, facilitated process to bring forth our best ideas for a sustainable campus, starting with and building upon the 160+ sustainability proposals generated this fall. The Board’s recent commitment to make the planned Biology, Engineering, Psychology building a model for environmentally intelligent construction practices is just the beginning. The Managers have already made it clear that they are willing to commit substantial resources to help Swarthmore become a leader in the efforts to combat climate change.
Expert facilitator, Sandy Wiggins, guided students, faculty, and staff through a refinement of ideas into a concrete list at the end of the two days. These facilitated sessions were enhanced by presentations from sustainability experts David Orr, Nikki Silvestri, Hunter Lovins, Bill Browning, John Fullerton, Greg Kats, and Kevin Hydes. Their collective insights throughout the intensive two-day process helped shape the conversation and sharpen our vision of the College’s future. Please click here for biographies for these invited guests.
This collaborative two-day event was a rare opportunity to learn from experts while simultaneously formulating the College’s efforts to address the challenges of climate change as a community. The challenges posed by climate change are unprecedented, but the opportunities those challenges present—opportunities to recreate our society on a more just, equitable, and humane basis—are also unparalleled. A summary of the charrette outcomes and next steps [PDF].
* A charrette is an intensive, collaborative effort to complete a solution to a complex problem before a given deadline. The deadline provides a sense of urgency that heightens creativity and teamwork. Charrettes are often used in urban planning and building design to bring together citizens, government officials, and experts to gather input and create joint ownership of a project.
Community Activism
Members of Mountain Justice hold a 32-day sit-in in Parrish Hall for fossil fuel divestment. At an April faculty meeting, 39 members of the faculty vote in favor of, with three voting against and three abstaining, a resolution calling for the College to partially divest from fossil fuel investments within separately managed accounts.
Zero-Waste Week
Green Advisors, a student group that facilitates environmentally-friendly campus living, sponsors a zero-waste week.
Environmental Sustainability Framework
The College launches its Environmental Sustainability Framework, a set of guidelines for capital projects and facilities operations anchored in its previous climate commitments. The Framework includes analyses of stormwater management, carbon, and energy - as well as sustainable building guidelines and a project checklist.
2016
Carbon Charge
In February, the Board of Managers allocates $300,000 for a new carbon charge, providing support for campus initiatives and projects that increase energy conservation and efficiency and promote renewable energy.
Sustainability Summit
Hosted by the Office of Sustainability in April, the inaugural summit draws a crowd of more than 200 individuals, including students, staff, faculty, and local community members. The summit features tabling by environmental student and community groups, interactive exhibits, poster presentations, and break-out sessions for attendees to share ideas for the future and to assess current sustainability efforts on campus. Additionally, speakers, including President Valerie Smith, address the audience with updates on the College's ongoing sustainability projects.
2017
Carbon Pricing
Following the successful launch of Swarthmore's internal carbon charge, President Valerie Smith sends a letter to more than 100 college and university presidents around the country asking them to consider supporting carbon pricing as a matter of policy. As a leader of this campaign, Swarthmore serves as a model for other institutions and advocates for carbon pricing at state and national levels.
2019
DECLARATION OF Climate Emergency
Underscoring the College's longstanding commitment to sustainability, President Valerie Smith signs the Sustainable Development Goal’s Climate Emergency Letter, adding Swarthmore College to a list of higher and further education institutions around the world that have collectively declared a global climate emergency.

Board of Managers Announces Plan to Reach Carbon Neutrality Goal by 2035
The College's ambitious energy plan, 20X35, charts a transformative path to efficient, combustion-free energy on campus. A central component of this plan is connecting buildings across campus to a heating and cooling geoexchange system. Powered by renewable energy, the process extracts heat from buildings during the summer and stores it underground for use in the winter — all while producing zero carbon emissions. Learn more.
