• After meeting the AB 32 goal in 2016, total included greenhouse gas emissions1 were 418.15 MMTCO2e in 2019, or 2.9 percent below the 1990 level of 431 MMTCO2e. GHG emissions decreased 1.6 percent in 2019 compared to 2018, the second largest percentage decrease since 2010 (first was 2016, when GHG emissions declined 2.7 percent compared to the previous year). The electric power sectors (in-state plus imports) contributed the most to the decrease (-4.28 MMTCO2e) followed by transportation (-3.63 MMTCO2e).

1 The GHG inventory was developed in accordance with the Intergovernmental Panel on Climate Change (IPCC) Guidelines for National GHG Inventories, the internationally recognized standard for developing national GHG inventories. There exist other categories besides included emissions: excluded emissions, carbon dioxide from biogenic materials, emissions and removals from forest lands and wood products, and other emissions. Excluded emissions are discussed elsewhere in this chapter.
