The Early Turnover Scheme (ETS) was first introduced in 2013 to incentivise owners of older diesel commercial vehicles and buses to replace them with a new, cleaner model. It initially covered the turnover of Pre-Euro and Euro 1 vehicles but was extended in 2015 to Euro 2 and 3 vehicles. It was extended to Euro 4 vehicles and further enhanced from 1 April 2021 until 31 March 2023. The ETS was further extended for another 2 years till 31 March 2025 with adjustments in the incentive quanta that took effect since 1 April 2023. After 31 March 2025, the ETS for eligible vehicles with MLW up to 3,500kg will cease, as announced in November 2022.

The ETS for HCVs, including Heavy Goods Vehicles, Very Heavy Goods Vehicles, Goods-Cum-Passenger Vehicles and buses, with maximum laden weight exceeding 3,500kg, will be extended till 31 December 2025 and will cease thereafter. The Government is studying other means to promote cleaner HCVs.

To be eligible for the ETS, vehicle owners must deregister their existing ETS-eligible HCV by 31 December 2025 and register its replacement vehicle by 30 January 2026 (replacement vehicle must be registered within one month of the deregistration date of the existing vehicle).

From 1 January 2026, the Heavy Vehicle Zero Emissions Scheme (HVZES) will replace the ETS. Vehicle owners who deregister their existing ETS-eligible HCV on 31 December 2025 and register a zero-tailpipe emissions HCV between 1 and 30 January 2026, may choose to receive either the ETS incentive or the HVZES incentive, but not both.

The incentive/surcharge quanta and pollutant thresholds for CVES are in Table 3. The incentives for ETS are in shown Table 4.

[1] Tailpipe emissions refer to air pollutants HC, CO, NOx and PM.[2] The same incentive applies if replacement vehicle is an HCV without tailpipe emissions. Owners who replace an existing LCV with an HCV with tailpipe emissions will not qualify for the ETS incentive.[3] The same incentive applies if replacement vehicle is a Band A LCV under the CVES.[4] The same incentive applies if replacement vehicle is a Band B LCV under the CVES.More details on the adjustments to CVES and ETS from 1 April 2025 can be found here: https://www.nea.gov.sg/media/news/news/index/commercial-vehicle-emissions-scheme-and-early-turnover-scheme-extended
