California Institute of Technology (Caltech) is a private research university located in Pasadena, California. Founded in 1891, Caltech is known for its strong emphasis on science and engineering, and has produced numerous Nobel laureates and other distinguished alumni. The university is also committed to sustainability and decarbonisation, and has taken a number of steps to reduce its carbon footprint and promote renewable energy.

One of the key ways that Caltech is working to reduce its carbon emissions is through the use of renewable energy. The university has installed a number of solar panels on its campus, which generate a significant amount of electricity. In addition, Caltech has signed a corporate power purchase agreement (PPA) with a renewable energy provider, which allows the university to purchase a portion of its electricity from renewable sources. This helps to reduce the university's reliance on fossil fuels and contributes to the decarbonisation of the energy sector.

Another way that Caltech is promoting sustainability is through its corporate energy program. This program aims to reduce the university's energy consumption and increase efficiency, through a range of measures such as energy audits, retrofits, and upgrades to lighting and HVAC systems. By reducing its energy use, Caltech is able to save money on utility bills and reduce its carbon footprint.

In addition to these initiatives, Caltech is also involved in research and development related to renewable energy and decarbonisation. The university's researchers are working on a range of projects, from developing new materials for solar panels to exploring the potential of hydrogen fuel cells. By pushing the boundaries of science and technology, Caltech is helping to drive innovation in the renewable energy sector and accelerate the transition to a low-carbon economy.

Overall, Caltech is a leading institution in the field of sustainability and decarbonisation. Through its use of renewable energy, corporate energy program, and research and development efforts, the university is demonstrating its commitment to reducing its carbon footprint and promoting a more sustainable future. As the world continues to grapple with the challenges of climate change, institutions like Caltech will play an increasingly important role in driving the transition to a low-carbon economy.
