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)

Tsinghua/Argonne Study Finds That Mass Use of EVs in China Could Result in Higher CO2 and Criteria Pollutant Emissions Than Conventional and Hybrid Gasoline Vehicles Due to Coal-Fired Generation of Electricity

Green Car Congress

The researchers found that while EVs do offer a very promising solution to energy issues due to their replacement of petroleum fuels, for now “ the high pollution levels of coal-fired power plants will trade off EVs’ potential energy benefits in China ”. The power of EVs is electricity from the grid.

Black carbon linked to increased cardiovascular risk; exacerbated by co-exposure to motor vehicle emissions

Green Car Congress

China’s particulate matter (PM) air pollution significantly exceeds health guidelines and is driven by industrial emissions, motor vehicles, and household use of biomass and coal fuels. Air pollution mitigation efforts focusing on reducing combustion pollution are likely to have major benefits for climate and human health. 1317176111.

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

Green Car Congress

The global energy supply became 6% cleaner from 1971 to 1990,in response to the oil shocks of the 1970s. Since 1990, however, the ESCII (2010 = 100) has remained essentially static, changing by less than 1%. The world must slow the growth of energy demand as well as make its energy supply cleaner, the IEA said. tCO 2 /TJ (2.39
