Pandemic lockdowns improved air quality in 84% of countries worldwide, report finds

(CNN) Coronavirus lockdowns led to air quality improvements in most countries, but the level of pollutants will likely rise as governments lift restrictions and economies swing back into gear, according to a new report.

IQAir's 2020 World Air Quality Report said human-related emissions from industry and transport fell during lockdowns, and 65% of global cities analyzed experienced better air quality in 2020 compared to 2019. Some 84% of nations polled reported air quality improvements overall.

"The connection between Covid-19 and air pollution has shone new light on the latter, especially as many locations have observed visibly cleaner air -- revealing that air quality improvements are possible with urgent, collective action," the report said.

Researchers from IQAir -- a global air quality information and tech company -- analyzed pollution data from 106 countries, specifically measuring PM 2.5, a microscopic pollutant that can cause serious health risks.

Singapore, Beijing, and Bangkok -- all of which imposed circuit-breaker lockdowns and widespread business closures -- saw the greatest reductions in PM 2.5. But this effect won't last: air pollution levels will likely rise as Covid-19 containment measures end and businesses restart, the report said.

Maybe outside. My wife says our house smells like farts all the time since I work at home now.

That 16%: areas of China and India, and anywhere affected by major wildfires.
