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., Comparison of loads (kg/year) of PAHs from direct discharges from ships and atmospheric deposition to the Baltic Sea. Marine Pollution Bulletin , Volume 182, doi: 10.1016/j.marpolbul.2022.113904.

Swiss team concludes that particulate filters should be mandatory for GDI engines

Green Car Congress

Based on a three-year study of toxic and environmentally relevant pollutants from gasoline direct injection (GDI) engines, Swiss researchers have concluded that some GDI engines emit just as many soot particles as unfiltered diesel cars did in the past. Further, the GDI particles carry numerous carcinogenic substances. —Norbert Heeb.

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. Pollution from ships creates lines of clouds that can stretch hundreds of miles. The difference helps explain how much industrial pollution influences clouds. NASA Earth Observatory.

Ricardo demos real-world driving emissions testing at Air Quality show

Green Car Congress

The system uses absorption spectroscopy to monitor and record emissions from a vehicle’s exhaust as it passes by a road-side sensor. This data promises to play an important role in providing cities and local authorities with the insight they need to develop Clean Air Zones and other air pollution mitigation measures.

What Are the Environmental Impacts of Tires

Clean Fleet Report

Marion, OH Most people have heard of exhaust emissions, but there is another form of emissions released by vehicles known as non-exhaust emissions (NEEs). Leachate was considered the main driver of toxicity in both organisms, with the particles themselves enhancing the toxicity in comparison to the leachate alone.

ICCT finds growth in shipping in Arctic could increase pollutant emissions 150-600% by 2025 with current fuels

Green Car Congress

Comparison of the potential reduction in emissions with the application of lower sulfur 0.5% While that report projected vessel activity, it did not explore the environmental impacts of increased shipping in terms of air emissions or the potential climate impacts from increases in short-lived climate pollutants such as black carbon.

German OEMs to upgrade emissions control on 5.3M Euro 5 and 6 diesels, contribute to €500M Sustainable Mobility fund

Green Car Congress

With respect to the emissions updates, the OEMs must also provide proof that the changes do not negatively impact any other parameters relevant for type approval—such as pollutant and CO 2 emissions, fuel consumption, noise and engine power. Excessively high pollution affects air quality in many German cities.
