California GHG Inventory for 2015 — by GHG and Process

TreeMap notes:

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

User Interaction:

  • Hover over a category to display the 2015 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).
  • Left click to drill down into category details.
  • Right click to move up to parent category.
  • Press F11 to view full screen.

Category notes

  • CO2 equivalence based on Global Warming Potential values from IPCC Fourth Assessment Report
