California GHG Inventory for 2012 — by Category as defined in the Scoping Plan

TreeMap notes:

  • The surface area of each category is proportional to its GHG emissions;
  • The color reflects change in emissions since year 2000: neutral grey for no change, greener for larger decrease, browner for larger increase.

User Interaction:

  • Bring your pointer on a category to read the 2012 GHG emission estimate in Tg (i.e. million metric tonne) of CO2 equivalent and the change since year 2000 (2000 value = index 100 so index=80 means 20% decrease, index=200 means doubling).

Category notes

  • [1] Reflects emissions from combustion of natural gas, diesel, and lease fuel plus fugitive emissions
  • [2] These categories are listed in the Industrial sector of ARB's GHG Emission Inventory sectors
  • [3] This category is listed in the Electric Power sector of ARB's GHG Emission Inventory sectors
  • [4] Reflects use of updated USEPA models for determining emissions from livestock and fertilizers
  • CO2 equivalence based on Global Warming Potential values from IPCC Fourth Assessment Report
