Study: air pollution caused 1.1M deaths across Africa in 2019, toll from outdoor pollution rising

Green Car Congress

Air pollution was responsible for 1.1 Air pollution was responsible for 1.1 Deaths attributable to household air pollution and ambient particulate matter (PM 2.5 ) air pollution in Ethiopia, Ghana, Rwanda, and overall in Africa, 1990–2019. The most disturbing finding was the increase in deaths from ambient air pollution.

Microplastics in Arctic snow suggest widespread air pollution

Green Car Congress

Wind plays a role in carrying microplastics (MPs, shreds of plastic less than five millimeters long) to both the snowy streets of European cities and remote areas of the Arctic Ocean. They visited five ice floes by ship-based helicopters or dinghies during three expeditions.

Study links PM2.5 pollution with millions of preterm births globally

Green Car Congress

Recent research has suggested that exposure to air pollution could also be a risk factor. exposures, inclusion of provider-initiated preterm births, and exposure to indoor air pollution. There are many known risk factors for preterm birth—from the mother’s age, to illness, to poverty and other social factors. Malley et al.

WUSTL study finds use of air conditioning reduces in-car pollution

Green Car Congress

Traffic is a major source of harmful pollutants; daily peak exposures tend to occur near roadways or while traveling—or being stuck—on them. That gave them rare, real-world look at pollutant exposure. With windows closed, the pollutants took longer to enter the vehicle cabin, but also longer to exit it.

Berkeley Lab researchers launch projects to apply AI to optimize traffic and reduce pollution

Green Car Congress

Flow was launched in 2017 and released to the public in September; the benchmarks are being released this month. The researchers anticipate that the resulting analysis will allow them to gain insights into the sources and distribution of pollutants, and ultimately allow for the design of more efficient and more timely interventions.

ICCT life-cycle analysis finds no climate benefit in using LNG as marine fuel

Green Car Congress

However, the use of scrubbers has recently come under intense scrutiny and is undergoing regulatory review due to concerns about both the reliability of these systems to deliver consistent air pollution compliance and because of the water pollution produced by open-loop operations. 2017) that actual ship operations are different.

EEA report: EVs are better for climate and air quality

Green Car Congress

Battery electric cars emit less greenhouse gases and air pollutants over their entire life cycle than petrol and diesel cars, according to a European Environment Agency (EEA) report. Shifting to electric vehicles could also reduce noise pollution, especially in cities where speeds are generally low and traffic often stands still.
