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. Source; EPA.

ExxonMobil Outlook projects hybrids and advanced vehicles to account for nearly 50% of cars globally by 2040; fuel demand for for personal vehicles to peak and decline, while commercial transportation demand rises 70%

Green Car Congress

While oil will remain the most widely used fuel, overall energy demand will be reshaped by a continued shift toward less-carbon-intensive energy source as well as steep improvements in energy efficiency in areas such as transportation, where the expanded use of advanced and hybrid vehicles will help push average new-car fuel economy to 48 mpg (4.9

Tsinghua University provincial-level lifecycle study finds fuel-cycle criteria pollutants of EVs in China could be up to 5x those of natural gas vehicles due to China’s coal-dominant power mix

Green Car Congress

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. According to the 12 th Five-Year Plan of the China Coal Industry (2011?2015)

Technology warming potential (TWP) for three sets of natural gas fuel-switching scenarios. (A) A) CNG light-duty cars vs. gasoline cars; (B) CNG heavy-duty vehicles vs. diesel vehicles; and (C) combined-cycle natural gas plants vs. supercritical coal plants using low-CH 4 coal.

Georgia Tech study suggests unlinking EVs from CAFE and coordinating with power sector for low-cost benefits

Green Car Congress

For the study, they define EVs as including both battery-electric (BEV) and plug-in hybrid electric (PHEV) vehicles. Only in the case of high EV market share and a high renewable electricity standard (RES) do EVs make a material contribution to greenhouse gas (GHG) reductions, they found. Credit: ACS, Choi et al.

IEA: carbon intensity of global energy supply has barely changed in last 20 years; “window of opportunity in transport”

Green Car Congress

The IEA said that this reflects the continued domination of fossil fuels—particularly coal—in the energy mix and the slow uptake of other, lower-carbon supply technologies. In 2012, sales of hybrid-electric vehicles passed the one million mark. In 1990 the underlying carbon intensity of supply was 57.1 tCO 2 /toe).
