According to the Vietnam Register, all newly assembled or imported cars have to meet the requirements of Euro 5 emissions standards from the 1st January 2022. Euro 5 standards have stricter and highest requirements on air emissions as well as newer technologies compared to other standards of Euro 3 and Euro 4. Since 1st January 2017, Euro 3 has been applied for two-wheeled motorcycles, while Euro 4 applied for cars using petrol and other fuels (except diesel). One year later, all diesel vehicles were required to follow Euro 4.
However, it is challenging that there are no stations that provide petrol or fuels suitable for the requirements of Euro 5 emissions. This mismatch can cause some operation failures. Depending on specific failures and manufacturers’ policies, customers can be supported in handling the problem and maintenance, said the Vietnam Automobile Manufacturers’ Association.
Cars and motorcycles are one of the major sources of air pollution in terms of emissions like carbon dioxide, hydrocarbons, nitrogen oxide, particle pollution, and toxins in fuel (e.g., benzene), especially in urban areas. In the latest national thematic report on the environment for the period 2016 – 2020, air pollution is the environmental hotspot in Vietnam.
