How China's horrific air quality magically turns cleaner: cotton

Green Car Reports

China is known for having some of the most polluted air in the world. But officials in one Chinese city found a way to at least make that air appear cleaner, for awhile. Like many Chinese cities, Xi'an, the provincial capital of Shaanxi, in the northern part of the country, has air-monitoring equipment.

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.

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. and NO x emissions.

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

Green Car Congress

Black carbon (BC) from incomplete biomass and fossil fuel combustion is the most strongly light-absorbing component of particulate matter (PM) air pollution and a major climate-forcing emission. Baumgartner and her colleagues measured the daily exposure to different types of air pollutants, including black carbon, in 280 women (mean age 51.9
