Technology dependent BC and OC emissions for Danmark, Greenland and the Faroe Islands calculated for the time period 1990–2030

This paper explains the first emission inventory for BC and OC for Danish sources related to fuel combustion for the historical 1990–2008 period and the forecast years 2009–2030. The core basis for the BC/OC inventory is the Danish TSP emission inventories and projections. The relevant BC/OC emission factor information is based primarily on the European models GAINS and COPERT IV. Residential sources are the largest contributor to TSP, BC and OC emissions, representing in 2008 70%, 62 % and 83% of the total, followed by road transport exhaust and non exhaust, other mobile sources and other stationary sources. The total Danish emissions of TSP, BC and OC decrease by 14%, 28% and 12%, respectively, from 1990 to 2030. The emissions for Greenland and the Faroe Islands are less than 1% of the Danish total. sidential wood combustion a small number of detailed BC/OC measurements are available from the literature. These emission data are, however, disregarded in the Danish case, either due to lack of combustion unit representation, or data being related to wood type not accounted for in the Danish fuel data. To improve the inventory in this part, more emission measurements are needed especially for new stoves and boilers, which will become increasingly dominant in the future. ivate stoves as such, it is desirable to develop a functional filter technology in order to bring down the particulate emissions in the future just as efficiently as for road transport and larger non road mobile machinery types. rk presented in this paper may serve as an input for policy makers dealing with the environmental impacts from combustion related BC and OC emissions. Further the calculated results can be used for air dispersion modelling purposes following a spatial distribution of the detailed emission inventory data.
