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. The number of vehicle miles traveled (VMT) by light-duty vehicles (i.e.,

lower in 2017 than the prior year (after accounting for sequestration from the land sector), and power sector emissions fell 4.2%, according to the 2019 edition of the US Environmental Protection Agency’s (EPA) annual report on greenhouse gas (GHG) emissions. Year-over-year, US greenhouse gas emissions were 0.5%

Consumption-based power mixes and NG transmission distances by Chinese province in 2010. In regions where the share of coal-based electricity is relatively low, EVs can achieve substantial GHG reduction, the team reports in a paper in the ACS journal Environmental Science & Technology.

EIA projects US energy-related CO2 emissions to remain near current level through 2050; increased natural gas consumption

Green Car Congress

In the United States, emissions associated with the consumption of petroleum fuels—motor gasoline, distillate, jet fuel, and more—have consistently made up the largest portion of CO 2 emissions. Natural gas surpassed coal to become the most prevalent fuel used to generate electricity in the United States in 2016.

EIA: light duty vehicle energy consumption to drop 25% by 2040; increased oil production, vehicle efficiency reduce US oil and liquid imports

Green Car Congress

Energy consumption by light-duty vehicles in the United States, AEO2013 and AEO2014, 1995-2040 (quadrillion Btu). The fuel economy of gasoline-powered LDVs continues to increase, and advanced technology fuel efficiency subsystems are added, such as micro hybridization, which is installed on 42% of gasoline LDVs in 2040.

ANL: life-cycle water consumption of fuel cell vehicles can be cut in half compared to that of conventional ICE vehicles

Green Car Congress

The life-cycle water consumption of fuel cell electric vehicles using hydrogen produced from natural gas with steam methane reforming is almost 50% less than the life-cycle water consumption of conventional internal combustion engine vehicles using gasoline, according to a study by researchers at Argonne National Laboratory (ANL).

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.
