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 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. —Platt et al.

UK ONS report finds significant challenge remains to reduce road transport emissions; sector GHG emissions up 6% from 1990-2017

Green Car Congress

New registrations of gasoline-fueled cars continued to increase in 2018, while those of diesel continued to decrease, leading to the proportion of all licensed cars that were diesel falling for the first time in 20 years. Diesel use exceeded gasoline use from 2005 onwards. of all new vehicle registrations.

the pollutant emissions discharged at the tailpipe outlet will be so low as to be hardly measurable, and their practical impact on air quality will be negligible. A transition from the gasoline or diesel ICE to a full gasoline/diesel hybrid can significantly reduce emissions. —Reitz et al. g/bhp-h or 15–20?mg/km).

EEA report: EVs are better for climate and air quality

Green Car Congress

Battery electric cars emit less greenhouse gases and air pollutants over their entire life cycle than petrol and diesel cars, according to a European Environment Agency (EEA) report. For local air quality, electric vehicles also offer clear benefits, mainly due to zero exhaust emissions at street level.
