Yale introduces innovative carbon charge program with 20 ‘living laboratories’ around campus
Yale University has launched a first-of-its-kind pilot program to put a price tag on the use of carbon — with some of the most prominent campus buildings playing a role in the experiment.
The program demonstrates Yale’s role as a leader in climate change research and sustainability efforts at a time when world leaders are convening in Paris to discuss measures for limiting global carbon emissions. Yale recently signed a White House climate change pledge that calls for a firm agreement to emerge from the Paris climate summit.
Twenty Yale buildings — including the Peabody Museum of Natural History, the School of Management’s Evans Hall, the School of Medicine’s Yale Physicians Building, and Yale Divinity School’s Sterling Divinity Quad — are taking part in the new carbon charge pilot program. So is Woodbridge Hall, the administrative home of Yale President Peter Salovey.
“The carbon charge concept originated as a proposal from Yale undergraduate and graduate students interested in using our campus as a living laboratory for applied research,” said Salovey, who announced the program with Provost Benjamin Polak. “Students were an integral part of the Presidential Carbon Charge Task Force, and many continue to serve in the pilot. Yale’s carbon charge pilot project is an exciting example of how students, faculty members, and staff can collaborate to build a more sustainable and innovative Yale.”
Placing a monetary value on carbon use is considered critical to creating an effective sustainability strategy and is a growing trend in the private sector. The idea is to prompt behavior changes at the individual and organizational levels by putting a price on the carbon dioxide used. Carbon dioxide is a byproduct of all activities that rely on the combustion of fossil fuels for power.

Yale has approximately 350 buildings and uses 3.6 million MMBTU of energy each year. The university generates 60% of its own power at its two co-generation power plants. The remaining electricity is purchased from United Illuminating Co., and natural gas is purchased from Southern Connecticut Gas to power the power plants. The university emits roughly 300,000 tons of carbon dioxide a year. In 2005, Yale pledged to reduce its primary greenhouse gas emissions 43% below 2005 levels by 2020. The university remains on track to meet this ambitious goal.
In 2014, Salovey outlined six sustainability initiatives for Yale, noting that, “Global climate change and its consequences are critical challenges for our time, and Yale has important and necessary roles to play in addressing them.” The initiatives included a $21 million capital investment in energy conservation and greenhouse gas reduction, an expansion of renewable energy, third-party verification of Yale’s greenhouse gas emissions, and the formation of the Presidential Carbon Charge Task Force.
The task force, chaired by Sterling Professor of Economics William Nordhaus, began looking into the feasibility of an internal carbon-pricing program in 2014. Earlier this year, the group presented its recommendations to Salovey. Among those recommendations were that Yale set a carbon charge at the social cost of carbon, currently estimated by the federal government to be $40 per ton of carbon dioxide.
“A key element is that the carbon charge program would expand Yale’s role as a pioneer in research, teaching, and designing practical applications of energy and climate policies,” Nordhaus said. “It would thereby contribute to society’s learning about ways to slow climate change while advancing Yale’s educational mission.”
One novel aspect of Yale’s pilot program is that it is essentially a quartet of experiments to find the best approach to carbon pricing. Each experiment will have five Yale buildings testing a particular manner of carbon pricing:
- A market-based model will have Yale units competing with one another to earn rebates.
- A target-based model will ask Yale units to meet specified carbon-use goals, in order to earn rebates that are applied to the unit’s annual budget.
- An investment model will have Yale units paying a monthly carbon tax for the year. At the end of the year, units will get the money back, with a stipulation that a percentage of the returned money be spent on additional energy-saving measures within their building.
- A price signal approach will present Yale units with detailed information about ongoing energy use, along with comparable information about past years’ energy use. The units also will receive regular updates on how their performance would translate into a straight carbon tax payment at the social cost of carbon, purely for informational purposes.
“This will help us arrive at the best model for Yale and allow us to share the lessons we learn with other institutions. That’s a key aspect of the program,” said Ryan Laemel, Yale’s carbon charge project coordinator. “There is no one-size-fits-all approach that works for internal carbon pricing.” (See “How Yale’s Carbon Charge Project Works,” below.)
“We believe that this pilot project can serve as a model for other institutions, expanding Yale’s role as a pioneer in researching, teaching, and designing climate change solutions,”
The pilot program includes classrooms, residential colleges, laboratories, and offices. Other buildings taking part include Berkeley, Jonathan Edwards, and Pierson residential colleges; the Gilder Boat House; Kroon Hall; and the Yale Health Center.
“It goes beyond simply diversifying the size of the buildings or their carbon footprints. It includes a range of different activity types, budgeting categories, utilities used, building users, and equipment contained,” said carbon charge project manager Jennifer Milikowsky, who is a recent graduate of the joint degree program at the School of Forestry & Environmental Studies and the School of Management. “By doing this we’ll begin to learn how the success of the policies we are testing is influenced by these different characteristics and will help as we continue to expand and improve this project.”
In their announcement, Salovey and Polak noted that feedback from participants and an analysis of the program’s results would inform a broader campus conversation on the topic. “We believe that this pilot project can serve as a model for other institutions, expanding Yale’s role as a pioneer in researching, teaching, and designing climate change solutions,” they said.
