By the middle of 19, most provinces and cities have implemented the national emission standards 4 and above, except for some provinces and cities that retain the national emission standards 3.
The background is that with the continuous development and progress of the economy, in order to protect the environment and reduce pollution, all provinces and cities have re-established automobile emission standards.
Let's take a concrete look:
1. Implementation of national five standards: most cities in Shandong, Jiangsu, Guangdong, Zhejiang, Fujian, Hebei, Liaoning and other provinces, Zhengzhou in Henan, Haikou in Hainan, Taiyuan in Shanxi, xi 'an in Shaanxi, and Beijing, Shanghai and Tianjin.
The second is to implement the four national standards: Henan, Hubei, Shanxi, Jiangxi, Qinghai, Shaanxi, Anhui, Guizhou, Gansu, Xinjiang, Hainan, Jilin, Sichuan, Tibet, Inner Mongolia, Guangxi, Yunnan, Hunan and other major cities and Chongqing, Yancheng, Jiangsu and Zhangjiakou, Hebei.
Third, the implementation of national emission standards: Jixi, Shuangyashan, Heihe and Suihua in Heilongjiang; Anshun, southwestern Guizhou and southern Guizhou; Jilin Baishan; Karamay, Turpan, Changji, Bortala, Bayinguoleng, Aksu, Kizilsu, Hotan, Tacheng, Altay, Tumushuke, Wujiaqu, tiemenguan, Shuanghe, Kokdala and Kunyu in Xinjiang; Alxa League, Inner Mongolia; Linfen, Shuozhou, Shanxi; Nanchang, Jiangxi.
From the above point of view, the environmental protection requirements in developed areas such as the eastern coast of China are stricter than those in the central and western regions, and Beijing, Shanghai and other regions have taken a step towards the national six standards. Therefore, you must pay attention to the local emission standards when buying used cars. Don't buy a car and find that you can't go home. Awkward.
