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.

Carnegie study finds climate impact of particulates varies greatly depending on where the pollution originated

Green Car Congress

Identical total annual emissions of sulfate and black carbon aerosol from eight major past, present, and potential future emitting regions (a) result in global-mean cooling spanning a 14x range (b, y-axis), differing substantially in the degree to which that cooling is felt in the emitting region (b, x-axis). This work is part of a larger $1.5-million

U Toronto studies find traffic emissions spread farther than thought; 25% of cars causing 90% of pollution

Green Car Congress

A trio of recently published studies from a team of University of Toronto engineers has found that air pollution could be spreading up to three times farther than thought, contributing to varying levels of air quality across cities. We used to think that living near a major road meant that you lived near a lot of air pollution.
