Road transport
The step-wise lowering of the sulphur content in diesel fuel has brought along a substantial decrease
in the road transport emissions of SO (Figure 3.35) In 1999 the sulphur content was reduced
2
from 500 ppm to the present level of 50 ppm (the same as for gasoline). Since Danish diesel and
gasoline fuels have the same sulphur-percentages at present, the 2003 shares for SO emissions and
2
fuel use for passenger cars, heavy-duty vehicles, light-duty vehicles and 2-wheelers are the same in
each case; 55, 26, 18 and 1%, respectively (Figure 3.39).

Historically the emission totals of NO X and especially NMVOC and CO have been very dominated
by the contributions coming from private cars, as shown in the Figures 3.36-3.38. However, the
emissions from this vehicle type have shown a steady decreasing tendency since the introduction
of catalyst private cars in 1990 (EURO I), and the introduction of even more emission efficient
EURO II and III private cars (introduced in 1997 and 2001, respectively). In general, the total emission
reductions of NO X , NMVOC and CO are fortified by the introduction of new gradually stricter
EURO emission standards for all other vehicle classes. For 2003, however, the significant increase
in the diesel fuel use causes the NO X emissions to increase for light and heavy-duty vehicles.
In 2003 the emission shares for passenger cars, heavy-duty vehicles, light-duty vehicles and 2wheelers
were 46, 38, 16 and 0%, respectively, for NO X , 74, 9, 7 and 10%, respectively, for NMVOC
and 87, 2, 6 and 5%, respectively, for CO (Figure 3.39).
