Swarthmore's Carbon Charge Program

Climate change exacerbates resource scarcity and conflicts, displacement of vulnerable communities, extreme weather, and other impacts. Beyond vast implications for ecological and public health, the climate crisis threatens all life on Earth. To avert the worst impacts and keep global temperature rise below 2 degrees Celsius, greater than 80% of remaining fossil fuels must remain unburnt. A sufficiently strong price on carbon presents a fair, feasible, and effective policy to align our economy with that target. To model this policy solution at a college scale, Swarthmore College established its internal Carbon Charge in 2016 with four primary goals:

  • Educate our community about carbon pricing as part of the solution to the climate crisis
  • Incentivize reductions in Swarthmore’s greenhouse gas emissions
  • Provide an ongoing source of capital for projects that reduce greenhouse gas emissions on campus
  • Build momentum for state, national, and global implementation of carbon pricing
 

Developed by a Swarthmore faculty and staff reading group in summer 2015, in partnership with community stakeholders, Swarthmore's internal Carbon Charge consists of three components:

  • A school-wide fee on college departments for carbon emissions
  • A shadow price to motivate less carbon-intensive construction projects
  • Use of revenues from the charge to support energy efficiency projects, strategic planning to reduce emissions, and campus education and outreach. 

Beyond Swarthmore's campus, we are also working to educate our broader community  about carbon pricing policy solutions, collaborating with other institutions about internal carbon pricing programs, and lending Swarthmore's public voice to supporting a price on carbon. 
 

The Shadow Price

Constructing or renovating campus spaces requires many decisions based on thoughtful cost-benefit analysis. The use of a shadow price on carbon provides a framework for incorporating the negative impacts of Swarthmore’s carbon emissions, both on and off campus, into these cost-benefit analyses.

With a shadow price, the College makes decisions as though we would have to pay $100 per metric ton of CO2e emitted. To implement this tool, Swarthmore uses a life cycle cost analysis calculator that accounts for the cumulative emissions of the project. You can download the most recent version of Swarthmore's life cycle cost analysis calculator here (last updated August 16, 2017).

For example, if the College is constructing a new building, the project team may consider heating the building either with ground source heat pumps or with natural gas boilers. The graph below demonstrates how a shadow price would find that a ground source heat pump is a less expensive option because it takes into account the social cost of carbon.

Evaluated total cost = (first costs) + (life cycle costs) + ((mtCO2e) * (social cost/mtCO2e))

Fee on College Departments

To make the real costs of carbon emissions visible, foster a sense of collective responsibility for mitigating climate change, and generate revenue for sustainability projects, the College levies a carbon fee on each department for the costs of Swarthmore's annual carbon emissions. 

In 2015, Swarthmore was responsible for approximately 12,500 metric tons of CO2 equivalent of greenhouse gas from our heat generation and purchased electricity. The Board of Managers approved an annual charge of $300,000, which is levied on each office and department as a flat percentage of their total budgets, excluding salaries and benefits. The amount of the total fee is regularly updated based on new emissions and budget data. Annually, a number of offices and departments generously contribute additional funds, bringing our campus charge close to the estimated social cost of carbon and providing us with greater resources to undertake emissions reductions projects.  

The revenues collected through the fee contribute to the Carbon Charge Fund, which is overseen by the Carbon Charge Working Group. Read more about the use of the fund below. 
 

Use of Carbon Charge Revenues

Allocated by the Carbon Charge Working Group, the Carbon Charge Fund supports renewable energy, efficiency upgrades, improved metering, emission reductions, and education initiatives. In 2019-20, the Carbon Charge raised slightly more than $300,000, allocated to the following categories:

  • $200,000 for energy saving projects through the Green Revolving Fund
  • $90,000 for research, analysis, strategic planning, and metering
  • $10,000 for education, engagement, and learning opportunities

The Green Revolving Fund

2016-17 President’s Sustainability Research Fellow Aaron Metheny ‘18 worked with the Carbon Charge Committee and Ecosphere Executive Committee to develop Swarthmore’s Green Revolving Fund.

Swarthmore’s Green Revolving Fund is a self-renewing pool of capital that grants loans to energy projects on campus. As the energy projects reduce utility expenses, the savings are returned to the revolving fund until the “loan” is paid off, which replenishes the fund for further projects. The project loans are managed through the Green Revolving Investment Tracking System. Examples of past and current projects include steam pipe insulation improvements and LED lighting upgrades for the Lamb-Miller Fieldhouse, Tarble Pavilion, and Science Center.

More information about the Green Revolving Fund is included in the GRF Guiding Document, which was approved by the Ecosphere Executive Committee in Spring 2017 and updated in 2019.

Research, Analysis, and Strategic Planning 

The Carbon Charge Committee values an informed approach to emissions reduction, utility planning, renovations, and resilience. The Carbon Charge Fund has been used to support projects such as the development of the Roadmap to Zero energy master plan, electricity meter installations in several campus buildings, and consulting support to solicit project bids for an off-site, utility-scale renewable energy project.

Education, Engagement, and Behavior Change

The committee also collaborates with groups on campus to raise awareness and understanding of carbon pricing on campus and in the higher education community. For example, these funds have been used to fund a delegation for the People’s Climate March and a pilot project, as part of the President’s Sustainability Research Fellowship, to install devices to measure and reduce electricity consumption from outlets in several campus buildings.

Collaboration with Other Institutions

Swarthmore is among a small group of schools with internal carbon prices. For example, Yale University is piloting structures for an internal carbon price to find the most effective policy for emissions reduction at a university. Vassar College incorporates a shadow price and robust life cycle cost analysis policy into its decision making.

Together, we are working to share the lessons and best practices learned on our campus and help other institutions institute carbon pricing and replicate a shadow price in their institutional context. Swarthmore is a leading contributor to the Internal Carbon Pricing in Higher Education Toolkit, which provides guides, case studies, and resources to institutions looking to build new internal carbon pricing programs. The Toolkit launched at the 2018 Global Climate Action Summit with an address from Former Secretary of State John Kerry.

Swarthmore is also a member of the Carbon Pricing Leadership Coalition, which brings together leaders from government, the private sector, academia, and civil society to expand the evidence base for the most effective carbon pricing systems and policies. President Smith contributed a commentary to their 2018-19 annual report.
 

Advocating for a Price on Carbon

In Fall 2016, Swarthmore President Valerie Smith was the second signatory of the Put A Price On It campaign's letter calling on elected leaders to take action on carbon pricing. She stated: 

“As leaders of higher education institutions, we call upon our elected representatives to act collectively on behalf of current and future generations by putting a price on carbon. We work to prepare our students for thriving futures, over which climate change casts a dark shadow of uncertainty. Putting a price on carbon pollution is an indispensable step we can take to effectively combat climate change.”

Awards

Swarthmore was honored to receive a 2017 Sustainable Campus Excellence Award in the Innovative Collaboration category from the International Sustainable Campus Network (ISCN) for developing our Carbon Charge program and helping to design tools for how to implement a carbon charge in other institutions.

In 2019, Swarthmore was recognized with an Excellence in Sustainability Award from the National Association of College and University Business Officers for our leadership in carbon pricing.
