California GHG Inventory for 2015 — by Economic Sector & Activity
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, green for decrease, brown for increase.
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
- Economic sectors and activity categories allow for comparison with other ARB emission inventories, which are similarly categorized.
- CO2 equivalence based on Global Warming Potential values from IPCC Fourth Assessment Report
