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. —Jenny Stavrakou.

Researchers use Google Street View cars for high-resolution air pollution mapping

Green Car Congress

demonstrated a measurement approach to for urban air pollution mapping at 4–5 orders of magnitude greater spatial precision than possible with current central-site ambient monitoring. Air pollution varies very finely in space, and we can’t capture that variation with other existing measurement techniques. —Apte et al.

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

Green Car Congress

Identical total annual emissions of sulfate and black carbon aerosol from eight major past, present, and potential future emitting regions (a) result in global-mean cooling spanning a 14x range (b, y-axis), differing substantially in the degree to which that cooling is felt in the emitting region (b, x-axis). This work is part of a larger $1.5-million

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.

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.
