EPA GHG Inventory shows US GHG down 1.7% y-o-y in 2019, down 13% from 2005

Green Car Congress

This decrease was driven largely by a decrease in emissions from fossil fuel combustion resulting from a decrease in total energy use in 2019 compared to 2018 and a continued shift from coal to natural gas and renewables in the electric power sector. CO 2 emissions decreased 2.2% from 2018 to 2019. Total GHG emissions in 2019 were up 1.8%

Rhodium Group estimates US GHG emissions rose 1.3% in 2022

Green Car Congress

This reversal in 2022 was primarily driven by a drop in emissions from the electric power sector, mostly due to the displacement of coal by natural gas and an increase in renewable energy. In the first quarter of 2022, fuel demand in the transportation sector, including gasoline, jet fuel, and diesel, rose slightly.

EPA: US greenhouse gases dropped 3.4% in 2012 from 2011; down 10% from 2005 levels

Green Car Congress

According to the report, GHG emissions in 2012 showed a 10% drop below 2005 levels, and were only slightly above the emissions in 1994 (6,520 million metric tons). CO 2 emissions are produced by the electricity generation sector as they consume fossil fuel to provide electricity to one of the other four end-use sectors.

EPA annual inventory shows US GHG up 3.1% from 2017-2018

Green Car Congress

This increase was largely driven by an increase in emissions from fossil fuel combustion, which was a result of multiple factors, including more electricity use greater due to greater heating and cooling needs due to a colder winter and hotter summer in 2018 in comparison to 2017. Source: EPA. >.

EPA: US GHG fell 0.5% y-o-y in 2017; power sector down by 4.2%, transportation up 1.21%

Green Car Congress

This decrease was largely driven by a decrease in emissions from fossil fuel combustion, which was a result of multiple factors including a continued shift from coal to natural gas and increased use of renewables in the electric power sector, and milder weather that contributed to less overall electricity use.
