UK researchers report that alcohols in windshield washer fluid are major unreported source of VOCs emissions from cars, including EVs

Green Car Congress

In a recent open-access paper published in ACS’ Environmental Science & Technology , researchers from the University of York report that alcohols in windshield washer fluid account for a larger fraction of real-world vehicle emissions than previous estimates have suggested. —Cliff et al.

UC Riverside study finds emissions benefits for E15 blend in California

Green Car Congress

A study by a team from UC Riverside has assessed the potential of increasing ethanol content in California reformulated gasoline (CaRFG) by investigating the exhaust emissions from a fleet of 20 Tier 3 light-duty vehicles. Acetaldehyde and ethanol emissions responded strongly with ethanol across the fleet of 20 vehicles.

CARB releases results of multi-year E15 study; multiple air quality benefits with slight reduction in fuel economy

Green Car Congress

The California Air Resources Board (CARB) has released the results of a multiyear study evaluating exhaust emissions from the use of California Reformulated Gasoline (CaRFG) that contains 15 volume percent ethanol (E15). The vehicle test matrix had provisions for five vehicles on each emissions standards category (i.e.,

UK ONS report finds significant challenge remains to reduce road transport emissions; sector GHG emissions up 6% from 1990-2017

Green Car Congress

A new report by the UK’s Office for National Statistics (ONS) finds that greenhouse gas (GHG) emissions from road transport in the UK rose by 6% from 1990 to 2017. The increase—albeit lower than the increase in road traffic—highlights the significant challenge in reducing emissions from road transport, the report says.

Study measures the effect of regional change in clouds caused by ships’ emissions; masking GHG warming

Green Car Congress

This puffy line is not just exhaust from the engine, but a change in the clouds that’s caused by small airborne particles of pollution. Small particles in exhaust from burning fossil fuels creates “seeds” on which water vapor in the air can condense into cloud droplets.

DLR: cleaner aircraft emissions reduce the climate impact of contrail cirrus

Green Car Congress

Fewer soot particles in the exhaust stream of aircraft reduces the formation of ice crystals and therefore the climate impact of the resulting contrail cirrus. Impact of a reduction in initial ice crystal number, as may be caused by reduced soot emissions, on global contrail cirrus properties. Burkhardt et al. —Ulrike Burkhardt.

US study of miners links heavy exposure to diesel exhaust to increased risk of lung cancer death; researchers suggest implications for urban areas with high exhaust concentrations

Green Car Congress

In a study of non-metal miners in the US, federal government scientists report that heavy exposure to diesel exhaust increased risk of death from lung cancer. For never-smokers, risk of lung cancer death increased with increasing diesel exhaust exposure. effect of diesel exhaust exposure on lung cancer mortality in.
