Non-road fuel consumption and pollutant emissions FOEN 2008 114 oxide emissions, the factors in the Emission Inventory Guidebook are slightly higher than those in this non-road inventory.

Appendix 115 > Appendix A1 Calculation methodology This appendix contains a detailed description of the methodology for calculating emissions, which involves 4 steps: > Calculation of inventories for each machine segment and year of manufacture > Calculation of operating hours for each machine segment and year of manufacture > Differentiation of inventory/operating hours by emission stages > Calculation of pollutant emissions All required input data are shown against a grey background. 1. Calculation of inventories for each machine segment and year of manufacture 1a: Calculation of inventory for each segment. Segments are divided into machine type (Makat), engine type (Mtyp) and engine-power class (Gklasse). N Seg = N Makat , Mtyp, Gklasse = N Makat ⋅ β Makat , Mtyp, Gklasse Key: N Seg = no. of machines per segment N Makat = no. of machines per machine type β Seg = distribution of engine types and engine-power classes for a given machine type 1b: Differentiation of inventory/operating hours by year of manufacture with the aid of age distribution N Seg , Bjahr = N Seg ⋅ϖ Seg Key: N Seg, Bjahr = no. of machines per segment (Seg) and year of manufacture (Bjahr) ϖ Seg = age distribution in inventory differentiated by segment (Seg)
