This project updates the Danish 1985-2004 inventory of fuel use and the emissions for non road machinery and recreational craft. The emission components covered are SO2, NOx, NMVOC, CH4, CO, CO2, N2O, NH3 and TSP . The inventories are based on new stock and operational data for the most important types of machinery and updated fuel use and emission data for the non road sector in general. The fuel use and emission results are aggregated into subtotals for agriculture, forestry, industry, household/gardening and inland waterways. In addition a 2005-2030 fuel use and emission forecast is presented. The project is funded by the Danish Environmental Protection Agency (Environmental project no. 1092)
