Beijing Morning News (reporter Zhang Lu) The Ministry of Environmental Protection informed the media yesterday morning that the implementation of emission reduction measures in various localities has initially appeared. From the current point of view, the actual daily average concentration of PM2.5 in Beijing has decreased significantly compared with the predicted value. The pollution levels of the 23 cities that initiated the Red Alert were all weaker than forecast, and about one-third of the cities had a one-step reduction in pollution levels.

The Ministry of Environmental Protection said that due to the reduction of pollutant emissions, the speed of pollution accumulation has slowed down, the process of heavy pollution has been delayed compared with the predicted results, and the peak concentration has been reduced.

With the continuation of extremely unfavorable meteorological conditions, the pollution situation has increased from the 18th to the 19th, with the first high value and the second high value on the 21st, and the specific effectiveness of emission reduction measures needs further observation and evaluation. The Ministry of Environmental Protection will increase supervision and inspection, strictly urge local governments to implement countermeasures, severely crack down on illegal pollutant discharge against the wind, and do its best to reduce the impact of heavily polluted weather.

On December 15, the Ministry of Environmental Protection urgently dispatched 13 inspection teams to supervise the emergency response to heavily polluted weather in 23 cities in Beijing, Tianjin, Hebei, Shanxi, Shandong, Henan and other provinces and cities. Up to now, 23 cities have issued red warnings for heavily polluted weather and launched first-level emergency response measures. The inspection found that all localities actively organized and carried out response work in accordance with the emergency plan for heavily polluted weather, sent a supervision team to the scene to supervise and inspect, and urged enterprises to implement emergency emission reduction measures.
