In line with the trend of tightening environmental regulations around the world, the Thai government would go ahead with the enforcement of Euro 5 emission regulations in 2024.
Currently, the Euro 4 standard is the mandatory minimum standard for fuels used in Thailand, although that would change in 2024. Currently, Euro 4 limits place restrictions on the amount of carbon monoxide (CO), hydrocarbons (HC) and nitrogen oxides (NOx). As well as reducing those pollutants, Euro 5 further limits the amount of non-methane hydrocarbons in the exhaust.
One type of particulate matter, for instance is the soot seen in vehicle exhausts. It can also be caused by unburned carbon in gas or oil. To meet the stringent new requirements, all new diesel cars should be specially fitted with particulate filters.
Apart from the enforcement of EURO 5 standard in 2024, the Thai government would also work on the environmental enforcement of waste produced from power plants and sewage released from various types of buildings.
Additionally, the Thai government is consulting internally with all relevant agencies on the roadmap for enforcing Euro 6 standard in the country.
While Thailand is seeking internal consultations on the enforcement of Euro 6, the European Commission is expected to formalize the stricter Euro 7 standard in July 2022.
However, industry watchers highlighted that the new Euro 7 standard might not come into effect until later this decade and there were also concerns that countries that are slow to adopting the stricter standards might become “dumping grounds” for pollutive cars.
