What is the emission standard for 2019 vehicles?

[ElliottMarie]

Vehicles sold before July 1, 2019 could meet either the China 5 or China 6 emission standards, while those sold after July 1, 2019 definitely comply with the China 6 standard, as the sale of China 5 standard vehicles was prohibited after that date. Therefore, most vehicles sold after July 1, 2019 adhere to the China 6 emission standard. The differences between China 5 and China 6 standards are as follows: Carbon monoxide emission levels differ: China 5 allows 1,000 milligrams of carbon monoxide emissions, while China 6 permits 700 milligrams. Emission limits vary: China 5's emission limit is 0.0045 grams per kilometer, whereas China 6's is 0.25 grams per kilometer. Issuing authorities differ: The China 5 standard was issued by the Ministry of Environmental Protection, while the China 6 standard was jointly issued by the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection and Quarantine. Letter representations differ: China 5 is denoted by 'V', and China 6 is represented by 'VI'.
