Latest GHG Inventory shows California remains below 2020 emissions target; much steeper rate of GHG reductions required

Green Car Congress

California’s latest greenhouse gas data shows that while the state continues to stay below its 2020 target for emissions, there is much more work to do to achieve carbon neutrality by 2045. California statewide GHG emissions dropped below the 2020 GHG Limit in 2016 and have remained below the 2020 GHG Limit since then.
