Vehicle carbon emissions scheme under review - may include other pollutants

Cars are likely to have to be far cleaner than they are today to qualify for green incentives. The Straits Times understands that the Government is reviewing the Carbon Emissions-based Vehicle Scheme (CEVS), which currently dispenses rebates or surcharges according to how much carbon dioxide (CO₂) a car or taxi emits.

The revised scheme is likely to measure other pollutants emitted, such as nitrogen oxides, hydrocarbons and particulate matter. It could kick in as early as 1^st July, when the current scheme expires. However, the change could be delayed so as to be in line with the Euro 6 emission standards, which will take effect for petrol vehicles from September and diesel models from January next year.

The CEVS revision is likely to affect diesel vehicles most. Although they produce less CO₂ than petrol equivalents, diesel engines tend to emit more nitrogen oxides - which are harmful to the environment and can also lead to serious health issues - and particulate matter. The Land Transport Authority and National Environment Agency would not provide details when asked about the review.
