Chalmers study: ban on sales of fossil-fuel cars greatly reduces lifecycle GHG mainly due to tailpipe emissions; risk of carbon leakage in manufacturing

Green Car Congress

If a ban were introduced on the sale of new gasoline and diesel cars, and they were replaced by electric cars, the result would be a significant reduction in lifecycle carbon dioxide emissions primarily due to reduced tailpipe CO 2 emissions, according to a new lifecycle study by researchers at Chalmers University of Technology, Sweden.

Environment Canada/MECA team assesses black carbon emissions in GDI engine exhaust; evaluation of prototype gasoline particulate filter

Green Car Congress

BC mass emissions for all four GDI and PFI vehicles over the three different driving patterns. This may result in the need for new emissions control strategies—such as a gasoline particulate filter (GPF)—to enable compliance with California LEV III and US EPA Tier 3 particulate emissions standards.

A Bamboo Carbon Filter for Diesels Could Reduce Emissions

Cars That Think

Although the pollutant emissions of a diesel engine are less than those of a gasoline one, it still emits carcinogens, nitrous oxides, and soot. Older models don’t even have the emission-control features that newer ones do. To reduce emissions, diesel vehicles use filters that catch exhaust particles and other contaminants.

Study finds gasoline exhaust contributes more to formation of secondary organic aerosols than diesel

Green Car Congress

Contrary to expectations, exhaust from gasoline vehicles contributes more to the production of secondary organic aerosols (SOA) than exhaust from diesel vehicles, according to a new study by scientists from the Cooperative Institute for Research in Environmental Sciences (CIRES), NOAA’s Earth System Research Laboratory (ESRL) and other colleagues.

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 concludes a shift from gasoline to diesel engines is consistent with long-term climate mitigation efforts

Green Car Congress

Global-mean temperature change caused by car exhaust emitted from gasoline and diesel engines specified in the previous and upcoming European vehicle emission standards (EURO 3, 4, 5, and 6). The results are based on one-year pulse emissions in year zero, which would be emitted by an idealized 1000 km drive.
