Road transport
The CO emissions are directly fuel use dependent and in this way the emission development re-
2
flects the trend in fuel use. As shown in Figure 3.27 the most important emission source for road
transport is passenger cars followed by heavy-duty vehicles, light duty vehicles and 2-wheelers in
decreasing order. In 2003 the respective emission shares were 56, 25, 18 and 1%, respectively (Figure
3.30).
The majority of the CH 4 emissions from road transport come from gasoline passenger cars (Figure
3.28.). The emission increase from 1990 to 1996 for this vehicle category is a result of the somewhat
higher emission factors for EURO I gasoline cars (introduced in 1990) than the ones for conventional
gasoline cars. The emission drop from 1997 onwards is explained by the penetration of
EURO II and III catalyst cars (1997 and 2001) into the Danish traffic. The newer technology stages
have lower CH 4 emission factors than conventional gasoline vehicles have. The 2003 emission
shares for CH 4 was 83, 8, 5 and 4% for passenger cars, heavy-duty vehicles, 2-wheelers and light
duty vehicles, respectively (Figure 3.30).
