Chalmers study finds ship exhaust gas scrubbers responsible for up to 9% of certain hazardous emissions into Baltic Sea

Green Car Congress

New research from Chalmers University of Technology, Sweden, finds that the discharge water from ships’ exhaust gas treatment systems—i.e., scrubbers—is responsible for up to 9% of certain emissions of carcinogenic and environmentally harmful substances in the Baltic Sea—considerably more than was previously known.

Study finds long-term exposure to black carbon from traffic exhaust at residential address increases the risk of stroke

Green Car Congress

Long-term residential exposure to locally emitted black carbon (BC) from traffic exhaust increases the risk of stroke even in low-pollution environments, according to a study by researchers at Karolinska Institutet and other universities in Sweden. g/m 3 ) of black carbon from traffic exhaust, the risk of stroke increased by 4%.

EEA finds only mixed progress for Europe’s transport sector in meeting environment, climate goals; GHG emissions up 25% since 1990

Green Car Congress

Issues covered in the briefing include emissions, air pollution, noise and renewable energy and the impact of transport on ecosystems and biodiversity. Evolution of greenhouse gas (GHG) emissions in the EU-28 from 1990 to 2016. In 2016, average emissions decreased by 1.5 Air pollution. Source: EEA. g CO 2 /km, a 9.2%

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. Emissions are usually higher in the production phase of electric cars, but these are more than offset by lower emissions in the use phase over time.

Hydrogen Opposed Piston Engine Working Group formed

Green Car Congress

The direct injection two-stroke engine could be a very promising and interesting option for hydrogen combustion to achieve zero NO x because of its advantages of high-power density and inherent much lower NO x emissions. The only criteria emission of concern is NO x. If hydrogen combustion is sufficiently lean—i.e.,

Study finds automobile tires are a potential source of carcinogenic dibenzopyrenes to the environment

Green Car Congress

It has been estimated that the replacement of HA-oils will reduce the PAH emission originating from tire-tread-wear by 98%. Data available of dibenzopyrenes in other urban emission sources are diesel and gasoline particulate emissions. Non-exhaust traffic sources of particles. Using emission-factor models, 50?85%

Researchers use LCLS to get real-time view of chemical reaction; important insight into how catalysts work

Green Car Congress

Catalytic converters in cars, for example, reduce emissions by converting exhaust to less toxic compounds. This work was supported by DOE’s Office of Science, the Swedish National Research Council, the Danish Center for Scientific Computing, the Volkswagen Foundation and the Lundbeck Foundation.
