Study from Thuringia shows 50% of harmful soot comes from local sources, 50% from long-distance transport

Green Car Congress

Soot particles from oil and wood heating systems as well as road traffic can pollute the air in Europe on a much larger scale than previously assumed. During transport, ageing processes not only change the chemical composition of the particles, but also influence their physical properties (e.g. forest fires).

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. emissions are less important because of the low contribution of light duty vehicles to national PM 10 and PM 2.5

Northwestern/Princeton study explores air quality impacts of aggressive conversion to EVs

Green Car Congress

This despite evidence that suggests air pollution impacts from the transportation sector exceed those from greenhouse gases. … solar, wind, hydroelectric, and nuclear) as compared to the eastern US (EUS), where the electricity market is dominated by pollutant and precursor emitting combustion sources (i.e., —Schnell et al.

EPA: US greenhouse gases up 2% in 2013; increased coal consumption, cool winter

Green Car Congress

The increase from 2012 to 2013 was due to an increase in the carbon intensity of fuels consumed to generate electricity due to an increase in coal consumption, with decreased natural gas consumption, according to the report. The transportation sector was the second largest sector source, at 27%. Transportation End-Use Sector.

What is Electrification of Transportation?

Driivz

For the transportation sector, electrification means replacing fossil fuels with electricity as the means of powering light-duty vehicles, medium- and heavy-duty trucks, and buses. Globally, the transportation sector contributes about 25% of all CO2 emissions. Other advantages of electrification of transportation.

EEA report: EVs are better for climate and air quality

Green Car Congress

Battery electric cars emit less greenhouse gases and air pollutants over their entire life cycle than petrol and diesel cars, according to a European Environment Agency (EEA) report. Shifting to electric vehicles could also reduce noise pollution, especially in cities where speeds are generally low and traffic often stands still.
