Climate Action
Taking Action in a Changing Climate
Yale is committed to achieving zero actual carbon emissions by 2050 with an interim goal to reach net zero emissions by 2035. Net zero will be attained primarily by reducing campus emissions 65% below 2015 levels and, as needed, retiring high-quality, verifiable carbon offsets. Zero actual carbon emissions will be accomplished by fully minimizing campus emissions and deploying clean energy technology.
Our approach to climate action is university-wide. We are expanding Yale’s teaching and learning opportunities to address the complexity and scale of global climate challenges, investing in our campus infrastructure and emerging technologies to reduce our impact, and have adopted fossil fuel investment principles to help facilitate a shift toward a decarbonized energy future.
Yale’s Efforts
- We strive for responsible energy use through conservation, efficiency upgrades, and creative approaches to campus use.
- We work to ensure that energy generation on campus is as efficient and clean as possible.
- Our greenhouse gas emissions reduction strategy steadily moves us toward our zero emissions targets.
- We are purchasing and retiring high-quality, verified carbon offsets to meet our emissions goals when necessary.
What You Can Do
- The Yale Carbon Charge is testing how price signals impact behavior.
- Help us save energy while at work, in class, and as you go about your daily activities.
Our Objectives and Goals
Achieve carbon neutrality for Yale University by or before 2050
When completed in 2030, the Upper Science Hill Development will boast a series of new and renovated buildings that serve as a hub for Yale’s work in quantum and materials science, physics, and more. In support of Yale’s strategy to reach zero actual emissions by 2050, Yale Office of Facilities worked with its construction contractor to pilot the use of R-99 fuel in construction machinery on the project site. R-99 is a renewable, locally sourced fuel and cleaner alternative to diesel made from waste cooking oils, with a lower carbon intensity than petroleum-based fuel. R-99 is also powering construction equipment at the Yale Golf Course as part of a restoration project and may be used in other Yale projects in the future.
GHG Emissions Reduction Commitment
ON TRACK
By 2035, achieve net zero carbon emissions, and by 2050, achieve zero actual carbon emissions.
We achieved our original greenhouse gas (GHG) emissions reduction goal in 2020 when we reduced our net emissions by 43% below 2005 levels. As we work toward our 2035 goal, we have made significant advances in planning for decarbonization and have reduced our emissions by 28% below 2015 levels (our baseline year for reporting). For additional information about GHG reductions, visit our Greenhouse Gas Emissions page.
Carbon Neutrality Strategy
ACHIEVED
By 2019, develop a strategy to achieve carbon neutrality by or before 2050.
This goal was achieved in 2019. The new commitment to achieve net zero carbon emissions by 2035 and zero actual carbon emissions by 2050 has strengthened our planning for campus decarbonization, including establishing a zero-carbon-ready standard for campus development and planning for campus geothermal infrastructure.
Scope 3 Emissions Reduction Program
ON TRACK
By 2025, set targets and achieve emissions reductions for business travel, student travel, employee commuting, purchased goods and services, and waste.
Yale is in the process of setting new reduction targets for relevant scope 3 categories. Purchased goods and services and capital goods represent the most substantial portion of Yale’s scope 3 emissions, and—in collaboration with several peer institutions—we have advanced efforts to identify the most actionable areas related to purchasing.
For additional information about scope 3 emissions and our approaches to each category, visit our Scope 3 Emissions page.
Mitigation and Adaptation
Develop, test, and share climate change mitigation and adaptation strategies in support of overall regional resilience.
Campus Resilience Plan
ON TRACK
By 2025, complete the Yale Resilience Plan.
In 2023, the Yale Community Resilience Building Workshop convened representatives from 25 administrative departments, four professional schools, and several students and alumni. The group shared their observations and perspectives on how Yale can best prepare for future climate-related emergencies, resulting in a report with strategies to address climate adaptation across Yale and beyond.
Investment Opportunities
Incorporate the risks and opportunities associated with climate change and possible governmental responses to climate change in the evaluation of investment opportunities.
Yale Investments and Climate Change
ON TRACK
Encourage Yale’s external investment managers to consider the risks and opportunities associated with climate change in their investment processes with respect to Yale’s portfolio.
Following the adoption of the Fossil Fuel Investment Principles by the Yale Board of Trustees in 2021, the Advisory Committee on Investor Responsibility continues to work on the implementation of the five principles to Yale’s endowment. In addition, the Investments Office has an internal climate opportunities team that has been making sizable commitments to climate strategies across Yale’s various asset class portfolios.
