Abstract: This report explains the parts of the Danish emission inventories related to road transport and
other mobile sources. Emission results are shown for CO2, CH4, N2O, SO2, NOX, NMVOC, CO, particulate
matter (PM), heavy metals, dioxins and PAH. From 1990-2010 the fuel consumption and
CO2 emissions for road transport increased by 30 %, and CH4 emissions have decreased by 74
%. A N2O emission increase of 29 % is related to the relatively high emissions from older gasoline
catalyst cars. The 1985-2010 emission decrease for NOX, NMVOC, CO and particulates (exhaust
only: Size is below PM2.5) -52, -84, -81, and -65 %, respectively, due to the introduction of vehicles
complying with gradually stricter emission standards. For SO2 the emission drop 99 % (due to reduced
sulphur content in the diesel fuel), whereas the NH3 emissions increased by 2232 % (due
to the introduction of catalyst cars). For other mobile sources the calculated emission changes
for CO2 (and fuel use), CH4 and N2O were -2, 5 and -1 %, from 1990 to 2010. The emissions of
SO2, particulates (all size fractions), NOX, NMVOC and CO decreased by 88, 65, 17, 28 and 2 %
from 1985 to 2010. For NH3 the emissions increased by 17 % in the same time period. Uncertainties
for the emissions and trends were estimated.
Keywords: Road transport, military, railways, domestic navigation, domestic aviation, working equipment
and machinery, SO2, NOX, NMVOC, CH4, CO, CO2, N2O, PM, heavy metals, dioxin, PAH, greenhouse
gases, acidifying components.
