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. Despite this, research on the environmental and health impacts of tire wear has been neglected in comparison to the research and innovations dedicated to tackling fuel 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.

IHS: continued legislative focus on pollutants to drive sensor market for internal combustion engines

Green Car Congress

The global market for sensors used in internal combustion engines (ICE) is on the road of steady growth for the next few years, propelled by increasing utilization in engine management and exhaust aftertreatment, according to a new report from IHS Technology. IHS projects that sensor shipments for ICEs will top 1.34 billion in 2013.

Two new studies of road air pollution in London find detrimental effects on over-60s and unborn babies

Green Car Congress

Exposure to air pollution on city streets is enough to counter the beneficial health effects of exercise in adults over 60, according to new research led by Imperial College London and Duke University. Our research suggests that we might advise older adults to walk in green spaces, away from built-up areas and pollution from traffic.

Study found highly elevated PM2.5 in pre-COVID-19 subway air in NE US; NYC the worst

Green Car Congress

Our findings add to evidence that subways expose millions of commuters and transit employees to air pollutants at levels known to pose serious health risks over time. By comparison, aboveground air concentrations for all measured cities averaged just 16 ?g/m g/m 3 ), followed by the MTA New York at 251 ?g/m
