VOORBURG – Cars have become 70 percent cleaner over the past 15 years. The emission of particulate matter is much lower than previously assumed as a result.

The emission of particulate matter and nitrogen oxides by passenger cars has emerged to be about 5 to 15 percent lower between 1990 and 2005 than previously estimated, Statistics Netherlands (CBS) announced on Monday.

More accurate data on the number of kilometres driven and new insight into the emission of air pollutants per kilometre driven have brought down the estimates of dangerous emissions, according to CBS.

CBS calculated that despite the 40-percent increase of the number of kilometres driven on the Dutch roads since 1990, the emission of almost all substances has fallen by 50 to 70 percent because of stricter EU environmental requirements for new vehicles.

Road traffic is a significant contributor to air pollution. In 2005 the share of traffic in national emissions of particulate matter, nitrogen dioxides and carbon monoxide was 19, 28, and 48 percent, respectively. Road traffic's share in carbon dioxide emission was 16 percent.
