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.

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.

KCL study finds London air pollution from traffic improving, but continues to exceed limits in many parts of city

Green Car Congress

New research by scientists at King’s College London suggests that air pollution from London’s roads is improving overall but more work may be needed to tackle some sources of traffic pollution, which continue to breach limits in many parts of the city. No data was available to compare trends in ΔPM 2.5 between the two periods.

MECA report finds additional NOx emission reductions from new heavy-duty trucks achievable and cost-effective (corrected)

Green Car Congress

The main conclusions in the 2020 report include: Engine and powertrain emission control technologies can enable simultaneous reductions in CO 2 and NO x by 2027. Commercially available engine efficiency technologies and advanced aftertreatment system designs can achieve a certification emission limit of 0.02 I apologize for the error.
