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

CARB approves updated “At-Berth” regulation, expanding efforts to cut pollution from ships in California ports

Green Car Congress

The California Air Resources Board approved a new regulation designed to reduce pollution further from ocean-going vessels while docked at California’s busiest ports. The rule requires that every vessel coming into a regulated California port either use shore power or a CARB-approved control technology to reduce harmful emissions.

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.
