(ECNS) -- Do you still remember the smoggy days ten years ago? Now they have gone.
According to the 2021 Beijing Ecology and Environment Statement released on May 11, 2022, the ecological environment continued to improve in the city, with its air quality meeting standards for the first time in 2021.
It was achieved by more than a decade of efforts. The average annual PM2.5 density was 33μg/m3(microgram per cubic meter) in 2021, down 63.1% from 89.5μg/m3in 2013. The average annual density of PM10, nitrogen dioxide, and sulfur dioxide have also met the national secondary standards.
There were 288 days with good air quality in Beijing in 2021, accounting for 78.9% of the whole year and increasing by 112 days over 2013. Citizens enjoyed more days with blue skies and white clouds.
Since the 18th CPCNational Congress, Beijing has given priority to energy conservation and efficiency to accelerate the construction of an ecological civilization and green Beijing. It has vigorously promoted high-tech industries with low resource consumption and pollution emission. Such strong measures have enabled the capital to achieve a green and low-carbon blueprint.
From being plagued by smog to having more blue skies, Beijing has made great strides in pollution prevention. Its ecological environment and air quality continue to improve, which was hailed by the United Nations Environment Programme as "Beijing Miracle."
