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.

Studies find global COVID-19 lockdowns have significantly reduced PM2.5 and NO2 pollution, but ozone up

Green Car Congress

Levels of two major air pollutants have been reduced significantly since lockdowns began in response to the COVID-19 pandemic, but a secondary pollutant—ground-level ozone—has increased in China, according to new research. For comparison, columns over the same time periods are shown for 2019.

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

However, aerosols have a much shorter lifespan in the atmosphere than the gases responsible for global warming, resulting in an atmospheric distribution that varies by region, especially in comparison to carbon dioxide. This work is part of a larger $1.5-million

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

Green Car Congress

For the first time, preliminary data recently reported to the EEA by Member States allow a comparison with the legally binding emission limits for 2010 set in the EU NEC Directive. These pollutants can cause respiratory problems, contribute to the acidification of soil and surface water, and damage vegetation. Jacqueline McGlade.

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.

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

Every air pollutant is more than 90% its limit. Similar compounds are also released from the tailpipe; these are regulated as part of a ‘total hydrocarbons’ measure. The two vehicles were less than one year old, had their original tires with similar tread depths, and closely matched mileage.

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

Green Car Congress

The report—“ Powertrain Sensor Market Tracker – H1 2014 ”—is part of the Semiconductors & Components service of IHS Technology. In comparison, to meet upcoming Euro 6 standards beginning in September this year, at least 20 sensors are needed—depending on the engine. billion units in 2019, up from about 1.08
