COVID-19 restrictions bring brief air-quality gains in 2020
Al Jazeera
WMO report says pandemic-related curbs temporarily improved air quality in number of places, especially in urban areas.
Pandemic lockdowns and travel restrictions caused dramatic but short-lived improvements in air quality and drops in pollution, the United Nations has said, but warned the blip was no substitute for long-term action. A new report on Friday from the UN’s World Meteorological Organization (WMO) found that COVID-19 restrictions last year temporarily improved air quality in a number of places, especially in urban areas. But they also spurred an increase in some pollutants that were both hazardous to health and had an unclear impact on climate change.More Related News
