CMU study finds that coal retirement is needed for EVs to reduce air pollution

Green Car Congress

Electric vehicles charged in coal-heavy regions can create more human health and environmental damages from life cycle air emissions than gasoline vehicles, according to a new consequential life cycle analysis by researchers from Carnegie Mellon University. Fossil fuel plants are the ones dispatched in response to new charging load.

Obama climate plan calls for new fuel economy standards for heavy-duty vehicles post-2018; cleaner fuels and investment in advanced fossil energy

Green Car Congress

Among the transportation-related elements of US President Barack Obama’s new climate action plan, which he is outlining today in a speech at Georgetown University, is the development of new fuel economy standards for heavy-duty vehicles post-2018. Earlier post.).

EIA projects decline in transportation sector energy consumption through 2037 despite increase in VMT, followed by increase

Green Car Congress

For the Transportation sector, EIA projects that energy consumption will decline between 2019 and 2037 (in the Reference case) because increases in fuel economy more than offset growth in vehicle miles traveled (VMT). However, US coal shipments, which are primarily via rail, decline slightly. trillion miles in 2018 to 3.5

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)

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. Fuel economy improvements accelerate where implementation of fuel economy standards and other policy measures has been scaled up, the report notes.
