A brief description of when and why the energy consumption baseline was adopted:

California implemented the legally binding Global Warming Solutions Act (AB32) in 2006, which commits the state to reducing its emissions to 1990 levels by 2020, and by an additional 80 percent by 2050.

Data source(s) and notes about the submission:

Stationary fuels, 99% of which are natural gas, are used to power the university's natural gas boilers, domestic water heaters, and cooking equipment. A few gallons of diesel are used to power the emergency generator.

Degree Days are provided by Skyfoundry in EcoVox, using a local sensor. File attached shows the location of this sensor and readings for 2022.
