Our Legacy of Sustainability and Climate Leadership
Cornell University's legacy of sustainability extends deep into our campus history, beginning with the principles upon which the University was founded in 1865.
From its inception, Cornell University has been a pioneer in reinventing education with a purpose. Visionary leaders Ezra Cornell and Andrew Dickson White rejected the social limitations of existing educational system of the 1800s, which typically accepted only white men of Christian denominations, and instead committed to advancing equitable educational access by creating an institution in which "any person can find instruction in any study.” This early commitment to social sustainability through access and equity was followed in later years by progress and leadership in other areas of sustainability, notably climate leadership and environmental care.

About this resource
This timeline was developed as part of the Environmental & Sustainability Communication Fellowship in the Campus Sustainability Office during 2018. The fellowship is an ongoing living laboratory program which partners students from the Communications Department at Cornell University with campus, regional, and global clients to advance environmental and sustainability strategy.
1865: Cornell Charter
New York Governor Reuben Fenton signs into law Cornell University’s charter on April 27, 1865. From its inception, Cornell has pioneered social sustainability for every person in the Cornell community and beyond. The University Charter states, “Persons of every religious denomination or of no religious denomination, shall be equally eligible to all offices and appointments.” Although Cornell’s nonsectarian and inclusive stance caused controversy in the mid to late 1800s, Ezra Cornell believed these ideals could only succeed as tenants for a university and for “true lovers of liberty” (letter by Ezra Cornell).
1868: Cornell Inauguration Day
Co-founders Ezra Cornell and Andrew Dickson White welcomed 412 students to Ithaca, New York. These students comprised the largest entering class admitted to any American college at the time. Due to the Morrill Land Grant Act, which passed in 1862, public lands in New York could be used to aid education in agriculture and the mechanic arts. Since its founding as a land-grant university, Cornell has sustained a rich history of partnering with New York State to benefit our broader society. Cornell Trustee Henry W. Sage writes to President White, advocating “for the education of women under the wing of Cornell.” The Trustees officially vote to accept women the following Spring of 1872. Both White and Cornell considered it essential to create a university open to all individuals, regardless of nationality, race, gender, or socioeconomic class. Both Cornell and White considered it essential to integrate agriculture and engineering with a broad liberal education, a groundbreaking approach for their times.
1985: ECI Launches
Cornell implements a program called the Energy Conservation Initiative (ECI), which has kept campus energy use relatively flat since 2000, despite a 20% growth in campus building square footage.
1997: Environmental Pledge
President Rawlings, Cornell officials, and student leaders sign a commitment to uphold sound environmental leadership. The new statement pledges support and participation from all levels of Cornell in protecting the environment and building sustainable futures for all. Participant Theodore L. Hullar, acting director of Cornell’s Center for the Environment, notes, “Especially important is the emphasis on sustainable futures, which aims to bring together optimally long-term environmental quality combined with economic and social vitality, for the continued fulfillment and enrichment of individual spirit and initiative.”
2000: Lake Source Cooling
Lake Source Cooling is pioneered by Cornell engineers. Replacing the need for refrigerants, this innovative renewable energy represents about an 86% reduction in energy use for campus cooling.
2001: Kyoto Protocol
Student activists lead a 7-day protest in front of Day Hall opposing the United States’ decision to refuse to sign the Kyoto Protocol. This protest leads to Cornell signing the Kyoto Protocol, becoming the first university in the nation to independently commit to this international agreement.
2004: Sustainability Intern

2005: Redbud Wood
The University had this patch of urban wildland, located near the intersection of University Avenue and Lake Street, leveled to make way for a 176-space parking lot as part of its West Campus Residential Initiative. The administration’s decision to pave over Redbud Woods was the cause of many well-publicized protests over a several year period by environmental activists including students and faculty. It also was the center of two legal battles between Cornell and the City of Ithaca. Despite the Court’s finding that Cornell could use the land, local community activism about the now demolished Redbud Woods has continued to persist.1
2007: Carbon Neutrality Commitment
President David Skorton signs the Second Nature Carbon Commitment, pledging to reach carbon neutrality, measure greenhouse gases, provide sustainability education for all students, and publicly report on these goals. Over 700 campuses have now signed Second Nature.

The Atkinson Center for a Sustainable Future is established as the first research center in America that unites the three pillars of sustainability (environment, social, and economic) within one center at Cornell.
2008: LEED Certification for Buildings
Cornell's Trustees approve a policy that Ithaca Campus new construction projects over $5M total must attain U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED) certification at a minimum of silver level. Projects must also achieve at least 30% energy savings compared to the baseline established by the American Society of Heating, Refrigeration, and Air-Conditioning Engineers – the national standard for energy efficient buildings.
2009: Climate Action Plan Launches
The Cornell community develops and implements our award-winning Climate Action Plan, committing to reach carbon neutrality by 2050. The President’s Sustainable Campus Committee (PSCC) forms to advocate for initiatives that enhance Cornell’s living laboratory for the environmental, economic, social, and academic dimensions of sustainability.

2014: First Large-Scale Solar Project
The Snyder Road Solar Farm goes live, producing 2.5 million kWh per year (about 1% of our total electricity use, or enough to power about 240 homes for one year). As the first large-scale project in the region – Cornell worked through several utility and state policy barriers paving the way for many others. The Snyder Road Solar Farm includes educational panels installed on a “tilt” racking system which allows for adjustment to facilitate research studies. In lieu of running gas-powered, carbon-dumping mowers to maneuver around 6,778 solar panels, the Snyder Road Solar Farm uses a flock of about 40 sheep to mow the fields.
2016: Building Automation
Cornell now uses the building automation (controls) to do lighting control instead of the industry standard of a separate, more expensive and harder to maintain proprietary lighting control system. A true paradigm change, this shift has won Cornell and our automated logic controls dealer Logical Control Solutions Project Of The Year international award for the recent redesign of Klarman Hall.
2016: Options for a Carbon Neutral Campus Report, Earth Source Heat
Cornell releases the report “Options for Achieving a Carbon Neutral Campus by 2035.” This report is first to recommend our current quadruple bottom line sustainability framework, an innovative form of analysis that evaluates projects affecting four categories: academic purpose, prosperity, people, and the planet. The report confirms Cornell’s goal of pursuing Earth Source Heat and renewable energy to heat and power the campus with carbon neutral sources.

2019: On Track to Neutrality
Between 2008 and 2019, the Cornell campus maintained a 36% reduction in greenhouse gas emissions from the 2008 baseline. Cornell's Ithaca campus has successfully reduced (and maintained a reduction) in greenhouse gas emissions which lead to climate change by 1/3. In the Fall of 2019, renewable energy provided 0% of our heating, 98% of cooling, and 10% of electricity needs. Projects that were implemented in the Fall of 2019 saved $1.2 million in energy costs, with $25 million cumulatively saved since 2008.
2020: 20MW Solar Farm Launched
