The new Carbon Emissions-based Vehicle Scheme (CEVS) is a very welcome move, but it is not without its faults, according to Koh Ching Hong, Managing Director of Borneo Motors and Singapore Institute of International Affairs (SIIA) corporate member.
A major feature of the CEVS is that it only covers carbon dioxide (CO2) but not other pollutants such as particulate matter (PM) or oxides of nitrogen (NOx).
"What we’re trying to say is that we are very supportive of clean air and CEVS, which is about carbon measurement. CO2 is about the climate but the other (pollutants) are about our health," Mr Koh said. "We’re also saying, why don’t we go one step further and measure other particulates too?"
He also remains to be fully convinced about the recent push for diesel passenger cars here, saying that under European emissions standards, petrol cars tend to outperform diesels in terms of PM and NOx, even if the opposite is true for CO2 and fuel efficiency. He also said diesel particulate filters tend to become clogged if constantly run at low speeds and in start-stop traffic normally seen in Singapore.
"So what most Japanese brands believe, and why Japan still doesn’t do much diesel, is that natural gas and petrol are clean and efficient enough," Mr Koh emphasised. "So what I’m saying is that we believe petrol with hybrids are the long-term solution in a city-state. Diesel is very good, but it’s better for long distances and highways."
