□释疑

1、为何要对国I国Ⅱ车采取区域限行?

机动车排放是北京PM2.5最大污染源

据北京市环保局机动车处处长李昆生介绍,目前北京市机动车保有量已达570万辆,每年排放污染物总量约为50万吨左右,排放的一氧化碳、氮氧化物、挥发性有机物,分别占到该类污染物全市排放总量的86%、56%、38%。在细颗粒物(PM2.5)本地污染贡献中,全年机动车排放贡献比例达31.1%,其中非采暖季机动车排放更是达到本地源排放的40%以上,可以说,机动车排放污染是我市本地PM2.5的最大来源。机动车排放的氮氧化物和挥发性有机物约有一半会转化成PM2.5,也是造成臭氧超标的主要因素,其中轻型汽油小客车排放的挥发性有机物占机动车排放总量的80%至90%。

2、国I国Ⅱ车限行的法律依据是什么?

依据《大气条例》制定限行政策

李昆生介绍,为了改善空气质量,依法治理大气污染,北京市广泛征求社会意见,借鉴国内外治理经验,于2014年3月1日,发布实施了《北京市大气污染防治条例》(以下简称《大气条例》),并于2014年3月1日起实施。

《大气条例》第七十二条提出,“市人民政府可以根据大气环境质量状况,在一定区域内采取限制机动车行驶的交通管理措施”,第七十八条提出“本市鼓励淘汰高排放机动车和非道路移动机械。市环境保护行政主管部门会同市财政、交通、公安、商务、质量技术监督等行政主管部门,根据本市大气环境质量状况和机动车、非道路移动机械排放污染状况,制定高排放在用机动车、非道路移动机械淘汰、治理和限制使用方案,报市人民政府批准后实施。”
