10. Spatial Resolution of the Diffuse Air Emissions in the E-PRTR- Jochen Theloke Degree of urbanisation (DGUR 2001) from EUROSTAT_GISCO The distinction is based on population densities three area types are defined as follows: “A” - Densely populated area: refers to a set of closely related local units, each one of which having a density greater than 500 [inhab/km²], and the total population of which being of at least 50 000 inhabitants “B” - Intermediate area: refers to a set of closely related local units that do not pertain to a densely populated area, each one of which having density greater than 100 [inhab/km²], and where the total population is at least of 50 000 inhabitants or it refers to a set that is adjacent to a highly populated area. “C” - Thinly populated area: refers to a set of closely related local units that are not part of a densely populated area or of an intermediate area.

11. Spatial Resolution of the Diffuse Air Emissions in the E-PRTR- Jochen Theloke Wood combustion Input data for Regionalization: Population on NUTS3 level Forest area from CLC on NUTS3 level  In generally thinly populated area has more forest area on NUTS3 level and vice versa

12. Spatial Resolution of the Diffuse Air Emissions in the E-PRTR- Jochen Theloke The most usage of Wood fuel is still in thinly populated area  the emissions are re-distributed on base of the assumption that in densely populated regions, the average wood consumption is about half of the amount used in thinly regions. Gas is located in most densely populated urban areas  the emissions are allocated under taken into account the assumption that in densely populated areas the share of households which are connected to gas installations are three times higher than in thinly populated areas. Oil and Coal is consumed independent from population density  the emission related to these fuels will be distributed by applying the overall population distribution. Oil, Coal Consumption Relation: A : B : C 1 : 1 : 1 Gas Connection Relation: A : B : C 3 : 2 : 1 Wood Consumption Relation: A : B : C 1 : 1.5 : 2 Energy consumption distinguished by fuel type for gridding

20. Spatial Resolution of the Diffuse Air Emissions in the E-PRTR- Jochen Theloke Result from the comparison of European data set vs. national specific approach (NL) CO-emissions (mainly wood related) 50 % of the cells have a deviation of at least 50% 20% of the cells have a deviation of at least 80 %  More populated areas partly underestimated  Less populated areas partly overestimated  NL specific: wood mainly used for creating a nice atmosphere. (+ glas of wine, dimmed lights, candles, snacks etc)  It will cost you extra, so it's more or less a hobby  Nearer to urban areas than to rural areas  In the Netherlands most houses are heated with Natural gas (>98%). There is a small amount of houses wich uses other fuels (oil, lpg, hardcoal, petroleum)  There are 9 categories of houses, depending on the age and type; there is applied factors to distribute the emissions. These factors differ depending on the fuel used. These factors are not per type of house, but a calculated factor including the number of houses within one of 9 categories.

Spatial Resolution of the Diffuse Air Emissions in the E-PRTR- Jochen Theloke Agricultural sector The emissions from 4B Animal husbandry and Manure Management and 4D Crop production and Agricultural soils are allocated on base of: animal census from EUROSTAT and FAO Corine Land Cover use On base of this information it is possible to allocate the diffuse emissions caused by each animal species and each pollutant in a high spatial resolution of 5 x 5 km² across EU27 + EFTA 4.

35. Spatial Resolution of the Diffuse Air Emissions in the E-PRTR- Jochen Theloke Conclusion  It has been developed a comprehensive methodology for allocate diffuse emissions over the whole EU27+EFTA4 domain in a consistent way and very high resolution (5x5km grid cells) for different sectors and pollutants  It has been further developed sector specific methodologies on base of recent available proxy data sets  The results have been and will be compared with NL specific data set based on base of a country specific approach  The data sets reliable in terms of an european consistency and the accuracy of the applied proxies  Future enhancements to other sectors, pollutants, countries proxy data sets and years are possible
