Cornell University is a private Ivy League research institution located in Ithaca, New York. Founded in 1865, Cornell has become one of the most prestigious universities in the world, with a reputation for excellence in research, teaching, and outreach. The university is organized into 14 colleges and schools, including the College of Agriculture and Life Sciences, the College of Arts and Sciences, the School of Hotel Administration, and the Weill Cornell Medical College.

As a leading academic institution, Cornell is committed to sustainability and decarbonisation, and has implemented a number of initiatives to reduce its carbon footprint and promote renewable energy. In 2007, Cornell signed the American College and University Presidents' Climate Commitment, pledging to become carbon neutral by 2050. Since then, the university has made significant progress towards this goal, reducing its carbon emissions by 36% since 2008.

One of the key strategies Cornell has employed to reduce its carbon footprint is the implementation of a corporate energy program. This program involves the installation of energy-efficient technologies and the use of renewable energy sources to power the university's operations. Cornell has invested in a number of renewable energy projects, including the installation of a 2 MW solar array on its campus and the purchase of renewable energy credits to offset its electricity use.

In addition to its renewable energy projects, Cornell has also implemented a corporate power purchase agreement (PPA) to support the development of new renewable energy projects. Under this agreement, Cornell has committed to purchasing a portion of the electricity generated by a 111 MW wind farm in Texas. This PPA not only supports the development of renewable energy, but also provides Cornell with a stable and predictable source of electricity.

Cornell has also implemented a number of energy efficiency measures to reduce its energy consumption and carbon emissions. These measures include the installation of energy-efficient lighting and HVAC systems, the implementation of building automation systems, and the use of energy-efficient appliances and equipment. Cornell has also implemented a green building policy, requiring all new construction and major renovations to meet LEED Silver certification standards.

In addition to its sustainability initiatives, Cornell is also committed to promoting sustainability and environmental stewardship through its academic programs and research. The university offers a number of courses and programs focused on sustainability, including a minor in sustainability, a master's degree in environmental sustainability, and a PhD program in sustainability. Cornell also conducts research on a wide range of sustainability topics, including renewable energy, climate change, and sustainable agriculture.

Overall, Cornell University is a leader in sustainability and decarbonisation, and has implemented a number of initiatives to reduce its carbon footprint and promote renewable energy. Through its corporate energy program, PPA, and energy efficiency measures, Cornell is demonstrating its commitment to sustainability and environmental stewardship. As a leading academic institution, Cornell is also promoting sustainability through its academic programs and research, and is helping to shape the future of sustainability and decarbonisation.
