After hard work, 2017 "temperament" is significantly improved in a blue sky defending battle between thousands of people’s well-being – the number of excellent days reached 235 days, and the excellent day ratio is%, PM10, concentration decreased by weight and% respectively . We not only completed the target tasks of the National "Atmospheric Ten", but also achieved the best level since the implementation of the new standards of environmental air quality in 2013. Make the total amount of pollutant emissions sharply, the ecological environment is significantly improved, and the level of green development is significantly improved, and it is the key to laying the pollution prevention and control.
In order to win the blue sky defend, enhance the people’s blue sky, Chengdu has been working hard.
