2月1日起,北京市将在全国率先执行更严格的“京”机动车排放地方标准,所有不符合该标准的轻型汽油车3月1日后一律停止销售和注册。
请看相关报道:
The capital will raise its automobile emission standards on Feb 1, making them the strictest in the nation in a move that the Beijing Environmental Protection Bureau said is expected to reduce auto pollution by 40 percent.
北京市将从2月1日起提高机动车排放标准,使其成为全国最严格的排放标准,北京市环保局称该标准实施后机动车污染有望减少40%。
Automobile emission standards指“机动车排放标准”,此次实行的是北京机动车第五阶段排放标准(fifth phase of emission standards),相当于欧洲5号标准(level V of European emission standards, Euro V)。新标准实施后,汽车尾气中的nitrogen monoxide(一氧化氮)的含量将减少40%,PM2.5含量也会相应下降。达到新排放标准的车辆将贴蓝色环保标志,可称为“蓝标车(blue label vehicles)。
自1999年起,北京根据车辆排放标准的不同,分别发放“黄色”或“绿色”环保标志。黄标车(yellow label vehicles)是“高污染排放车辆(heavy-polluting vehicles)”的简称,指连国Ⅰ排放标准都未达到的汽油车,或排放达不到国Ⅲ标准的柴油车。和黄标车相对的就是绿标车(green label vehicles),即汽车尾气排放达到欧洲1号或2号标准及以上的车辆。
