UC Daviss Greenhouse Gas Emissions Inventory
12
California Climate Action Registry

• The California Climate Action Registry was
  established by California statute as a non-profit
  voluntary registry for greenhouse gas (GHG)
  emissions.
• The Registry helps companies and organizations
  establish GHG emissions baselines against which
  any future GHG emission reduction requirements
  may be applied.

13
UC Davis GHG Inventory

• Baseline year 2005
• Reported CO2 for 2005
• Reported all six Kyoto Protocol gases for 2006
  (CH4, N2O, HFCs, PFCs, and SF6).
• UC Davis was the 3rd University of California
  campus to join the registry
