Singapore Amends Regulations Concerning Vehicular Emissions Tax and Vehicular Emissions Labelling 
In Singapore, the Road Traffic (Vehicular Emissions Tax) (Amendment) Rules 2023 and the Energy Conservation (Fuel Economy and Vehicular Emissions Labelling) (Amendment) Regulations 2023 were promulgated on March 31, 2023 and came into effect on April 1, 2023. The Regulations respectively amend the Road Traffic (Vehicular Emission Tax) Rules 2017, which stipulate the vehicular emissions tax to be imposed according to the emission level of the vehicle at the time of vehicle registration, and the Energy Conservation (Fuel Economy and Vehicular Emissions Labelling) Regulations 2012, which implements fuel economy labelling for vehicles as stipulated in Part 4 Division 1 of the Energy Conservation Act 2012. This amendment strengthens the vehicular emissions tax, especially for light commercial vehicles, and amends the requirements for documents that must be submitted for type approval for vehicular emissions labelling.

Amendment to the Road Traffic (Vehicular Emission Tax) Rules
Article 3 stipulates the vehicular emission tax for passenger cars and light commercial vehicles*. The amendment has strengthened the vehicular emission tax for small commercial vehicles. For light commercial vehicles registered for the first time between April 1, 2023 and March 31, 2025, if the pollutants in the exhaust gas meet any of the following new Class C standards, the vehicle is subject to a vehicular emission tax of 15,000 SGD (about 1.5 million yen). The new Class C standard is as follows:
* Light commercial vehicles: those with a maximum load of 3,500 kg or less and that are subject to additional registration fees under Article 7 of the Road Traffic (Automobile, Registration and Licensing) Rules.
Emission standards for light commercial vehicles (Class C)
| CO2 (g/km) | CO (g/km) | HC (g/km) | NOx (g/km) | PM (mg/km) |
|---|---|---|---|---|
| C > 216 | C > 0.270 | C > 0.025 | C > 0.015 | C > 0.85 |
In addition, the method for measuring and determining the emission level of CO2 is specified in Article 4 and the method for measuring and determining the emission level of pollutants other than CO2 is specified in Article 5 and the Third Schedule. With this amendment, the method for measuring and determining the emission level has also been revised as follows.
- In Article 4, the measurement method of CO2 emission level for passenger vehicles and light commercial vehicles (excluding electric vehicles, plug-in hybrids, and special light commercial vehicles**), as well as electric vehicles and plug-in hybrids, has been revised.
- In the Third Schedule, the method for measuring and determining the emission level of pollutants other than CO2 of gasoline vehicles has been revised.
** Special light commercial vehicles: those with a reference weight exceeding 2,610 kg and that are approved under the European Union’s Whole Vehicle Type-Approval System (WVTA) established under Regulation (EU) 2018/858, (EC) No 595/2009 and (EU) No. 582/2011.
Amendment to the Energy Conservation (Fuel Economy and Vehicular Emissions Labelling) Regulations
Article 3 stipulates the documents that must be submitted at the time of type approval of the vehicle subject to vehicular emissions labelling. The requirements for light commercial vehicles have been revised as a result of this amendment. The new requirements are as follows:
(A) Data on fuel and carbon dioxide emissions measured in accordance with the provisions of Commission Regulation (EU) 2017/1151, UNECE Regulation No. 154 or WLTP Japan; and
(B) Emissions measured in accordance with Articles 4 and 5 of the Road Traffic (Vehicular Emission Tax) Rules 2017.
In addition, it was stipulated that the emission level of particulate matter when the emission level of particulate matter is not measured in a gasoline light commercial vehicle that does not use a gasoline direct injection engine should be over 0.9 mg/kg from the conventional over 0.85 mg/km.
