New Emissions Analytics study suggests pollution from tire wear now 1,850 times worse than exhaust emissions

Green Car Congress

In early 2020, UK-based independent testing firm Emissions Analytics published a study claiming that tire particulate wear emissions were 1,000 times worse than exhaust emissions ( earlier post ). —Emissions Analytics. Quoting such ratios, however, needs careful interpretation.

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.

Eaton leverages cylinder deactivation and exhaust thermal management technologies to reduce commercial vehicle emissions

Green Car Congress

Power management company Eaton’s Vehicle Group has demonstrated cylinder deactivation (CDA) as an effective technology for meeting future global emissions requirements for diesel-engine powered commercial vehicles. New emissions regulations spearheaded by the California Air Resources Board (CARB), U.S. Rapid catalyst warm-up essential.

Study suggests particulates from brake dust may have same harmful effects on immune cells as diesel exhaust

Green Car Congress

Metal particles from the abrasion of brake pads (brake abrasion dust, BAD) may cause inflammation and reduce the ability of immune cells to kill bacteria, similarly to particles derived from diesel exhaust particles (DEP), according to a new study led by researchers at King’s College London. It is estimated that only 7% of PM 2.5

Study links ambient PM2.5 and ozone specifically caused by vehicle exhaust emissions to ~361,000 premature deaths worldwide in 2010 and ~385,000 in 2015

Green Car Congress

A new study provides the most detailed picture available to date of the global, regional, and local health impacts attributable to emissions from four transportation subsectors: on-road diesel vehicles; other on-road vehicles; shipping; and non-road mobile engines such as agricultural and construction equipment. of global ambient PM 2.5

A Bamboo Carbon Filter for Diesels Could Reduce Emissions

Cars That Think

Diesel cars are a popular choice for those looking to buy a used vehicle in Asia, Europe, and elsewhere. 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.

Study shows two-stroke scooters dominant source of air pollution in many cities; asymmetric polluters

Green Car Congress

A study by European researchers has found that two-stroke (2S) scooters, although constituting a small fraction of the fleet, can dominate urban vehicular pollution through organic aerosol and aromatic emission factors up to thousands of times higher than from other vehicle classes.
