Discrepency Between Territorial Emission Inventories for California #4

I noticed a discrepancy among various territorial emission inventories for the state of California. I am aware of three territorial inventories, one conducted by the EPA (https://cfpub.epa.gov/ghgdata/inventoryexplorer/), one conducted by the California Air Resources Board (https://ww2.arb.ca.gov/ghg-inventory-data), and one based on USEEIO State v1.1 (https://pasteur.epa.gov/uploads/10.23719/1531923/CA.html). The territorial inventory from USEEIO rose by around 7% from 2012-2019, however the territorial inventory from the EPA remains relatively stable, while the territorial inventory from CARB shows a 7% decrease throughout the same period. While the three territorial inventories are relatively close in terms of emissions (deviating by around 5-10%), what is more worrying is their divergence throughout the study period.
