生态环境部部长黄润秋回应环保关切

他说，二氧化硫等主要污染物的排放总量已降至目标水平以下。降低主要城市PM2.5浓度和改善全国地表水质量的目标也已经实现。PM2.5是一种导致雾霾的细微颗粒物。

The country reduced PM2.5 concentrations in cities above the prefecture level that had missed reaching the national standard of 35 micrograms per cubic meter. The goal was to reduce the density of the pollutant by 18 percent between 2017 and 2020.

Pm2.5不达标 By the end of last year, that decrease had reached 23.1 percent, he said.

他说，截至2019年年底，这一降幅已达23.1%。

Meanwhile, the country has seen the quality of 74.9 percent of its surface water be classified at or above Grade III－the third-highest in the country's five-tier water quality system－which is 4.9 percentage points higher than the target for 2020, he added.

他表示，一至三类 The proportion of water below the lowest level of Grade V in the country is expected to go down to less than 5 percent by the end of 2020. Monitoring shows, however, the proportion stood at 3.4 percent by the end of 2019.

劣五类水体，“十三五”的规划目标是要小于5%。监测指标显示，我们去年已经做到了3.4%。

While it's challenging to meet the other two targets－carbon dioxide emissions per unit of GDP and the ratio of days with fairly good air quality in major cities－"we are confident that we will complete it well", he said.
