北京机动车年排放污染物70万吨

2016-01-14 03:30:26    新京报

据悉,今年北京有望实施京六排放标准。

  追问3

  机动车限行减排效果如何?

2007年至今,北京共实施了6次单双号限行措施。

连爱萍介绍,机动车限行的减排措施比较明显,这不仅包括单双号限行,也包含对大货车、渣土车等重型柴油车的管控措施。评估结果表明,在几次重大活动期间,机动车限行措施对减排的贡献可达40%;在两次红色预警期间,减排贡献平均也在20%左右。

根据环保部门的评估结论,从北京的主要污染源排放清单分析,在现有的应急措施中,机动车限行措施的贡献应该是最大的,单双号加上货车禁行等,交通环境站点与城市环境站点气态污染物的浓度差异有所减小,交通环境在限行期间有所改善。

  京津冀如何联合治理机动车?

去年,《京津冀及周边地区机动车排放污染控制协同工作实施方案》发布,提出逐步实现机动车排放业务监管数据共享,以及区域机动车排放污染联防联控。

截至目前,北京已对2372辆排放超标外埠车执行了处罚。同时,北京正在协调国家有关部门提供车辆数据,搭建区域机动车排放数据库。

据了解,由于排放标准不统一、监管数据不共享、异地执法难等问题,此前对于外埠车在京排放超标的违法行为,北京的相关部门只能采取劝返的手段,没法处罚,所以很难对违法行为起到震慑作用。而成立上述的协作小组最终的目标,就是要建立区域统一的法规标准,实现区域内超标车的异地处罚。

  追问5

  老旧机动车淘汰有何措施?

在机动车治理方面,北京一直采取疏堵结合的方式,一方面提高新车的排放标准,另一方面促进高排放老旧机动车的淘汰。

去年,北京率先在全国基本淘汰黄标车的基础上,继续加大淘汰黄标车力度,对黄标车采取全市禁行、取消营运资质、停止定期检验等更严格的措施,实现了基本淘汰黄标车的目标。

同时,加大老旧绿标车的淘汰力度。北京从2011年开始利用经济政策鼓励淘汰老旧绿标车,去年共淘汰老旧车38.9万辆,提前超额完成市政府下达的“淘汰20万辆老旧车”的年度任务。
