Stricter Petrol Vehicle Emission Standards Preannounced

On 9 September 2016, the EPA preannounced the Sixth Phase of Petrol Vehicle Emission Standards, another step along the road to tackle vehicular air pollution. The sixth phase will begin on 1 September 2019, and existing vehicle models will be given a grace period of one year to allow owners to adjust to the new regime.

To improve air quality, the EPA continues to tighten the Vehicular Air Pollutant Emission Standards and preannounced the Sixth Phase of Petrol Vehicle Emission Standards. The tightening of standards is important for managing vehicle emissions and keeping Taiwan’s regulations in line with international environmental protection trends, while also stimulating domestic enterprises to develop, manufacture, or import eco-friendly vehicles that use the latest pollution control technologies. The EPA examined the EU Euro 6 emission controls before drafting the amendments to Article 3 of the Vehicular Air Pollutant Emission Standards.

The main points of the amendments involve tightening of pollutant controls and stricter regulations for importing in-use vehicles, as outlined below:

‧Adding new regul ations, the Vehicular Exhaust Air Pollutant Emission Standards for Petrol and Cleaner Alternative Fuel Engine Vehicles will take effect on 1 September 2019. Parallel systems will be maintained whereby Euro 6 vehicular emission standards and testing procedures will be applied, along with the worldwide harmonized light vehicles test procedures (WLTP) as well as recognizing US car emission standards and their Tier 2 Bin 5 testing procedures.

‧The unit of measurement for pollutant amounts has been changed from grams (g) to milligrams (mg).

‧The particulate matter (PM) limit has been tightened from 5.0 mg/km to 4.5 mg/km.

‧Particle number (PN) controls have been added, at 6 x 1011 #/km.

‧Imported in-use vehicles, regardless of the year of manufacture, should meet driving cycle test standards and idel test standards used for new vehicles. A grace period of three months from the date of announcement will be given to importers.

‧The amendments will take effect on 1 September 2019, and existing vehicle models will be granted a one-year grace period.
