Swarthmore's plans for reducing indirect emissions, known as Scope 3, is the next phase of its ambitious efforts to reach full carbon neutrality by 2035. Tackling Scope 3 emissions is challenging but necessary in order for the College to achieve its aim to eliminate or offset 100% of emissions, which also include Scope 1 emissions, tied to campus energy facilities, and Scope 2 emissions, tied to the energy the College purchases and consumes.

Scope 3 emissions are those not directly controlled by the College but critical to its operations, including employee commuting, air travel, solid waste, and more. As of fiscal year 2023, these emissions accounted for approximately 29% of Swarthmore’s total carbon output. The College’s Office of Sustainability, along with the Carbon Charge Working Group (CCWG) and partners across campus, has developed this comprehensive plan to strategically address and reduce these emissions.

"Scope 3 emissions reduction requires both innovation and a community-wide commitment. Together, we are making meaningful strides toward a sustainable future,” says Elizabeth Drake, assistant vice president of sustainability & strategic initiatives.

The Scope 3 Emissions Plan incorporates a variety of targeted strategies:

• Sustainable Commuting: The College will improve public transit access, specifically SEPTA; implement alternative commuting incentives; and increase the infrastructure necessary to support electric vehicle users. These initiatives are intended to reduce the environmental impact of the nearly 10% of emissions generated by employee commuting.
• Air Travel Management: Air travel emissions represent 14.35% (FY23) of the College’s carbon footprint. The College launched an air travel carbon fee in 2022 to fund offsets for emissions that cannot be avoided. Moving forward, Swarthmore will continue evaluating low-emission travel options, encourage sustainable travel practices among staff and students, and refine its carbon fee structure.
• Zero Waste by 2035: Solid waste, though a smaller contributor to emissions, is highly visible. With an ambitious goal of 90% waste diversion by 2035, Swarthmore is working to reduce per capita waste and expand campuswide recycling and composting efforts, reducing emissions while fostering a culture of sustainability.
• Water and Paper Efficiency: The College is committed to reducing emissions associated with wastewater treatment and paper use. Initiatives will include water efficiency upgrades and transitioning to high-recycled-content paper in campus printing.

“We have a significant opportunity to reduce Scope 3 emissions and this comprehensive plan furthers our community commitment to a more sustainable campus,” says Melanie Patapis, climate action manager.

Swarthmore’s commitment to carbon neutrality aligns with its dedication to fostering an inclusive, educational approach to sustainability. The CCWG has incorporated input from students, faculty, and peer institutions, aiming to make Scope 3 reduction a shared responsibility across campus. Furthermore, Swarthmore will continue to expand its research and partnerships, including support for innovative carbon offset projects.
