ICL briefing paper estimates that 52% of all small particle pollution from road transport comes from tires and brakes

Green Car Congress

A new briefing paper from Imperial College London estimates that in 2021, 52% of all small particle pollution from road transport came from tires and brakes. The Imperial researchers say that the effect of new technologies on the generation and impact of tire wear should be a priority. Scale bar of 10 μm = 0.01

Researchers clarify links between NOx and airborne sulfates to tackle hazy air pollution

Green Car Congress

Among pollutants that are less than 2.5 microns in diameter (PM2.5 ), airborne sulfate is one of the most common components of hazy air pollution formed atmospherically via the oxidation of sulfur dioxide (SO 2 ). In collaboration with the California Institute of Technology, a research team led by Prof.
