| China’s air quality saw “incomparable” improvements in the first quarter of this year as a coronavirus outbreak led to rapid declines in industrial activity and transportation, an environment ministry official said on Friday.
The number of “blue sky days” rose by 6.6 percentage points in the first quarter of 2020, said Liu Bingjiang, head of the air pollution office at the Ministry of Ecology and Environment. “That was a level we didn’t even dare imagine,” he said, noting the target for the whole 2016-2020 period was 3.3 percentage points. China has for several months been grappling with a coronavirus outbreak, which has spread around the world and infected more than 4 million people, forcing governments to impose strict lockdowns, severely hurting economic activity. With millions staying home, concentrations of small lung-damaging floating particles fell by nearly 15% in more than 300 Chinese cities in the first three months of the year, according to official ministry data. Emissions in the city of Shanghai fell by nearly 20% in the first quarter while Beijing’s average emissions levels stood still in the first three months of the year, the data showed. In Wuhan, where the pandemic originated, monthly averages of particulate matter emissions dropped more than a third. Normally the country’s smoggiest province, Hebei also saw PM2.5 concentrations, a measure of air pollution, fall 15.7% in the first four months of 2020. The province, however, attributed the drop to its crackdowns on pollution rather than the coronavirus. |
