In an ongoing effort to reduce campus waste, Housing, Dining and Hospitality introduced the Triton2Go reusable container program, replacing nearly 300,000 disposable containers since fall quarter 2020. UC San Diego received the City of San Diego 2020 Recycler of the Year Award for improving its waste diversion rate.

Campus utilities technicians installed over 250 utility meters that automatically detect leaks and warn staff who can address issues quickly, saving water and reducing maintenance costs. Total campus water consumption decreased by 14% compared to the previous year with major reductions in all areas, including a 20% reduction in industrial water used at campus utility plants. Additionally, overall energy consumption decreased by around 8%.

UC San Diego continues to leverage public funding to expand the campus electric vehicle charging infrastructure with 300 ports that serve commuters and the public. The campus is San Diego County’s largest multipurpose hub of EV charging plazas, delivering 2.5 gigawatt hours to more than 5,500 unique drivers. SANDAG recognized UC San Diego for excellence in promoting alternative commuting choices. Logistics added a second truck and a van to its electric delivery fleet.

The Sustainability Programs Office launched the Green Classroom Certification Program to help campus educators promote resource conservation and receive recognition for their leadership in sustainability. The office also encouraged graduating seniors to sign a pledge promising to consider the consequences of their workplace decisions to create a sustainable society.

Year
Metric Tons CO₂e in Thousands

In 2020, UC San Diego decreased its total greenhouse gas emissions by 36%, or over 94,000 metric tons of CO2e, from 2019. This reduction equates to the amount of greenhouse gas emissions from about 19,000 passenger vehicles driven for one year. This decline was a result of increased remote work and restrictions on travel due to COVID-19 as well as 100% clean power provided by UC’s Clean Power Program. (At the time of data collection, campus greenhouse gas emissions were not yet third-party verified. Updates will be made, as needed, in future reports.)

WATEr

In 2020 395 million gallons of portable water used. 2021 340 million gallons of portable water used

UC San Diego’s potable water use decreased by 14% from the previous fiscal year. This equates to a reduction of 54,955,560 gallons, or enough to fill approximately 83 Olympic-sized swimming pools. This decrease in overall water consumption was a result of increased remote work and reduced residential occupancy. This year’s report illustrates the difference in water consumption between fiscal year 2019–20 and fiscal year 2020–21 instead of measuring progress toward the 2025 goal. This data also includes water use from UC San Diego Health.
