生态环境部、发展改革委等10部门和北京、天津、河北等六省市人民政府近日联合印发《京津冀及周边地区2019-2020年秋冬季大气污染综合治理攻坚行动方案》，明确京津冀及周边地区2+26城市要全面完成2019年环境空气质量改善目标。
The number of days with severe pollution should fall by 6 percent from Oct 1 to March 31, and the average density of PM2.5--fine, breathable particles with diameters 2.5 micrometers or smaller--should drop by 4 percent compared with the same period last year, according to the plan.
方案明确，今年10月1日到明年3月31日，重度及以上污染天数同比减少6%，区域PM2.5（直径小于等于2.5微米的可吸入颗粒物）平均浓度同比下降4%。
2020年是打赢蓝天保卫战三年行动计划的目标年、关键年（a crucial year for China to win the battle for blue skies），2019-2020年秋冬季攻坚成效直接影响2020年目标的实现。
方案提出的具体目标举措还包括：
调整优化产业结构
The plan sets a deadline to close down some outdated production facilities and suspend some highly polluted industry capacities in Tianjin as well as Hebei, Shanxi and Shandong provinces by the end of this year.
2019年12月底前，天津、河北、山西及山东要淘汰一批老旧生产设备，关停部分高污染工业产能。
In Shanxi, for example, 1.75 million metric tons of steel capacity will be reduced, and outdated facilities that could produce 10 million tons of coke will also be shut down.
比如，山西省压减钢铁产能175万吨，关停淘汰焦炭产能1000万吨。
推进企业集群升级改造
By the end of this month, local authorities and enterprises in those regions are expected to have drafted a specific plan, setting a clear target and timeline to improve production quality and enhance pollutant emission standards to meet pollution control standards.
2019年10月底前，制定综合整治方案，统一时间表，提出具体治理任务，提高污染物排放标准，提升产业发展质量和环保治理水平。
加强排污许可管理
According to the plan, pollutant discharging licenses for construction material and furniture enterprises should be released by December.
2019年12月底前，完成人造板、家具等行业排污许可证核发工作。
高标准实施钢铁行业超低排放改造
Steel manufacturers in Hebei are required to achieve an extra-low emission transformation of 100 million tons by the end of the year, while the target in Shanxi over the same time frame is 15 million tons.
2019年12月底前，河北省完成钢铁行业超低排放改造1亿吨，山西省完成1500万吨。
有效推进清洁取暖
The plan also called for efforts to accelerate adjustment of the energy structure by effectively pushing clean heating and controlling coal consumption.
有效推进清洁取暖，控制煤炭消耗，加快调整能源结构。
