EPA: US GHG emissions in 2017 down 0.3% from 2016

Green Car Congress

The decrease in CO 2 emissions from fossil fuel combustion was a result of multiple factors, including a continued shift from coal to natural gas, increased use of renewables in the electric power sector, and milder weather that contributed to less overall electricity use. above 1990 levels in 2007. below 2005 levels.

EIA: US energy-related CO2 emissions down 1.7% in 2016; carbon intensity of economy down 3.1%; transportation emissions up

Green Car Congress

Emissions have declined in 6 out of the past 10 years, and energy‐related CO 2 emissions in 2016 were 823 MMmt (14%) below 2005 levels, according to the EIA. Among the findings of the EIA analysis: CO 2 emissions form natural gas surpassed those from coal in 2016. Motor gasoline accounted for 56.0% from the 2015 level.

EPA: US greenhouse gases up 2% in 2013; increased coal consumption, cool winter

Green Car Congress

The increase from 2012 to 2013 was due to an increase in the carbon intensity of fuels consumed to generate electricity due to an increase in coal consumption, with decreased natural gas consumption, according to the report. Commercial aircraft emissions increased slightly between 2012 and 2013, but have decreased 18% since 2007.

Motor gasoline consumption will be less than previously estimated. US energy-related carbon dioxide emissions remain more than 5% below their 2005 level through 2040, reflecting increased. CO 2 emissions per 2005 dollar of GDP have historically tracked closely with energy use per dollar of GDP. The share was 29% in 2007.).

EIA AEO2015 projects elimination of net US energy imports in 2020-2030 timeframe; transportation energy consumption drops

Green Car Congress

Fuel economy standards and changing driver behavior keep motor gasoline consumption below recent levels through 2040 in the Reference case. Improved efficiency in the end-use sectors and a shift away from more carbon-intensive fuels help to stabilize US energy-related carbon dioxide emissions, which remain below the 2005 level through 2040.
