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.

OSU researchers find small particles from tires inhibit growth of organisms in freshwater, coastal estuaries

about 30% of its tread erodes and enters the environment. million metric tons of tire wear particles flow into the environment each year in the United States. Exposure to nano tire particles enhanced toxicity in comparison to leachate alone. The researchers cite studies that show during the lifetime of an automobile tire.

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.

Air pollutant emission 2010 limits exceeded in twelve EU Member States; road transport NOx a main factor

Green Car Congress

Twelve European Union Member States exceeded one or more of the emission limits set by the EU National Emission Ceilings (NEC) Directive, according to recent official data for 2010 reported to the European Environment Agency (EEA). These pollutants contribute to health problems and can also lead to economic losses and environmental damage.

Study finds all-electric rideshare fleet could reduce carbon emissions, but increase traffic issues

Green Car Congress

They used the model and the data to estimate the life cycle air pollution, greenhouse gas, and traffic externality benefits and costs of serving rides based on Chicago TNC trip data from 2019 to 2022 with fully electric vehicles. The authors acknowledge funding from Carnegie Mellon University’s Wilton E. Scott Institute for Energy Innovation.

UNICEF: 300M children worldwide breathing air exceeding WHO pollution guidelines by 6x or more

Green Car Congress

Almost one in seven of the world’s children, 300 million, live in areas with the most toxic levels of outdoor air pollution—six or more times higher than international guidelines set by the UN’s World Health Organization (WHO)— according to a new UNICEF report. No society can afford to ignore air pollution.

Emissions Analytics argues that current Pareto-efficient solution for decarbonization would be hybrids, not BEVs, based on do-no-harm

Green Car Congress

Every air pollutant is more than 90% its limit. Do no harm’ means taking a step back from an intervention to look at the broader context and mitigate potential negative effects on the social fabric, the economy and the environment. The Tesla is, of course, zero on all these measures; upstream emissions were ignored in this test.
