Greenhouse Gas Inventory

Greenhouse Gas Emissions Inventory Overview



zero emissions vehicleGreenhouse gas inventories reveal that 75% of our emissions are associated with campus building energy use. The majority of the remaining emissions come from campus related travel.

UC Berkeley reports on ten emissions sources and analyzes emissions in three different categories:

  • Scope 1 - Direct Emissions: cogen natural gas, purchased natural gas, emergency generators, campus fleet, emissions from refrigerants
  • Scope 2 - Indirect Emissions: purchased electricity
  • Scope 3 - Optional Emissions: business air travel, student commute, faculty/staff commute, solid waste, water consumption, air travel

The campus reports its GHG inventory to both The Climate Registry and the California Air Resources Board (CARB). Third party verification of the inventory is completed as part of the reporting process.

Normalized Energy and Climate Data

The campus analyzes emissions, energy use, and transportation scaled to campus population and square footage over time to monitor normalized progress and for comparison purposes.

Carbon Footprint Lifecycle Analysis

UC Berkeley recognizes that the reported emissions inventory does not fully reflect the complete carbon footprint of campus activities. A lifecycle analysis includes greenhouse gas emissions from all stages of a product/service lifecycle, including mining, manufacturing, and transportation. UC Berkeley’s Renewable and Appropriate Energy Laboratory has provided some lifecycle analysis of campus emissions as have students in reports like this an award winning student research project.
