Non-road mobile machinery comprises of tractors, wheel loaders, excavators, articulated haulers and trucks etc. Non-road mobile machinery is almost exclusively equipped with diesel engine and thus significantly contributes to the overall emissions of pollutants in the society. In Europe non-road mobile machinery contributes with about 15 to 20% of the total emissions of nitrogen oxides Besides estimates of annual fuel consumption and emission amounts this report also include inventories of the number of machines and the annual work hours. In total 15 different types of non-road mobile machinery was identified, of which one was other machinery. Each type of machinery was further divided into three net power regions. Information concerning number of machines, annual work hour, rated engine power, load factor and fuel consumption and emission factors were obtained for each type of machine, power region and model year for the last 25 years. Annual fuel consumption and emissions amounts were individually calculated for each type of machine, net power region and model year. The methodology employed within this study differs to some extend to that of other recently conducted studies within the same area, emissions from non-road mobile machinery. Firstly, concern was taken to the age distribution, for example both the number of machinery and the annual work hour varies significantly with age or model year of the machinery. Secondly, both fuel consumption and emissions factors were individually adapted the each type of machinery and activity in order to better represent the actual use of the machinery and thus resulting fuel consumption and emissions. The fuel consumption and emission factors were based on the CORINAIR Emission Inventory Guidebook and European emissions regulations for non-road mobile machinery and adjusted for: - differences in quality and specification between the fuel stipulated for use during type approval and Swedish diesel of environmental class 1, - differences between the maximum value stipulated in the emission regulations and the recorded emission amounts during type approval, - differences in engine load between the test cycle employed during type approval and during real use of the machinery, and - deterioration in fuel consumption and emission formation with increasing age.This report comprises fuel consumption and emissions from non-road mobile machinery equipped with diesel engine with a rated power of 37 to 560 kW.
