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

⋅ϖ<br />
Seg<br />
Key: N Seg, Bjahr = no. of machines per segment (Seg) <strong>and</strong> year of manufacture (Bjahr)<br />
ϖ Seg<br />
= age distribution in inventory differentiated by segment (Seg)
