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 ). As testament to the filtration efficiency of the latest gasoline particulate filters (GPFs), tailpipe mass emissions are now as low as 0.02

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.

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. After all, diesel cars cost less to maintain, burn less fuel, and have a longer engine life. To reduce emissions, diesel vehicles use filters that catch exhaust particles and other contaminants.

UK government launches new clean air strategy; ending sales of conventional diesel and gasoline LDVs by 2040

Green Car Congress

UK Environment Secretary Michael Gove published a new Clean Air Strategy to cut air pollution backed up through new primary legislation. The UK said it will go further and faster than the EU in reducing human exposure to particulate matter pollution. Ending the sale of new conventional diesel and gasoline cars and vans by 2040.

UK researchers report that alcohols in windshield washer fluid are major unreported source of VOCs emissions from cars, including EVs

Green Car Congress

There are widespread policy assumptions that the phase-out of gasoline and diesel internal combustion engines will over time lead to much reduced emissions of Volatile Organic Compounds (VOCs) from road transport and related fuels. While some VOCs are released in exhaust, others may arise from an unexpected source—e.g.,
