  1. Scoping Plan; follows the categories identified in the ARB Scoping Plan.
  2. Process-oriented categories; follows the IPCC categorization to ensure comparability with international inventories.
  3. Economic sectors; enables comparison with other ARB emission inventories, which are similarly categorized.
