The University of California (UC) has reported savings of about $620 million since 2010 through energy efficiency improvements in its facilities, with $100 million saved in 2024 alone. These figures are detailed in UC’s latest Annual Sustainability Report and reflect both financial and environmental gains from efforts to reduce carbon emissions, minimize waste, and lower water consumption.
“There’s a general misconception that environmentally sustainable operations are more costly than doing business as usual,” said Nathan Brostrom, Chief Financial Officer at the University of California. “But what we’ve found over 22 years of setting and meeting ambitious sustainability goals at the University of California is that environmental and financial sustainability are two sides of the same coin, because using resources more efficiently often cuts costs as well. Decision-makers across the university are prioritizing sustainability projects and programs that also provide cost savings.”
One major initiative includes UC Berkeley’s plan to replace its four-decade-old central power and heat plant with an electrified heating and cooling system combined with a thermal energy storage tank. The campus estimates this upgrade will save $670 million over 25 years by reducing fossil fuel purchases and operating costs associated with outdated infrastructure. This project is part of a broader strategy outlined in a milestone report released last year, which details how UC plans to decarbonize operations by 2045 after input from students, faculty, and staff across all campuses.
UC Health has also contributed to cost reductions by reprocessing medical devices such as surgical instruments under FDA-approved procedures for cleaning and sterilization. In the past year alone, this practice saved $11.7 million while diverting nearly a quarter-million pounds of waste from landfills.
At UCLA Health, replacing approximately 10,000 fluorescent lights with LED bulbs resulted in utility savings of $120,000 within one year. The switch also reduced electricity usage equivalent to powering a thousand homes for a month and cut carbon emissions similar to those produced by driving a gas-powered car over half a million miles.
Construction practices have also shifted toward sustainability. At UC San Diego, transforming an old fishery building into the Marine Conservation and Technology Facility led to a 12% reduction in construction costs compared to building new. The renovated lab earned LEED Gold certification for its adaptive reuse approach.
Student-led initiatives have played a role as well. With support from UC’s Global Climate Leadership Council via a $10,000 grant, Associated Students of UCLA purchased reusable containers for campus cafés. In their first year of use, these containers saved $56,000 on single-use alternatives plus $8,500 on waste management expenses by keeping over 1,100 pounds of trash out of landfills.
Upgrading appliances has furthered savings at UC San Francisco where swapping out more than 130 specimen freezers for energy-efficient models led to electrical cost reductions totaling $174,000 in just over one year; projections suggest replacing all freezers could yield up to $2.3 million annually in energy savings.
