Non-road fuel consumption and pollutant emissions ... - BAFU - CH

Non-road fuel consumption and pollutant emissions FOEN 2008 18
The calculation methodology outlined above refers to the four classical pollutants:
carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NO x ) and particulate
matter (PM). The applied emission factors are machine-related and dependent on
machine operation. By contrast, CO 2 emissions are directly dependent on fuel consumption.
The corresponding conversion factors are indicated in Table 34 on page 134.
4.2 Inventory modelling
4.2.1 Structure
The inventory of non-road machines and appliances was carried out by Jaakko Pöyry
Infra (formerly Elektrowatt, EWI) in collaboration with other specialists (cf. A15)
(EWI 2005). For calculation purposes, the various machines and appliances were
divided into the following eight machine categories in accordance with the CORINAIR
definitions 4 :
> Construction machinery
> Industrial machinery
> Agricultural machinery
> Forestry machinery
> Garden-care/hobby appliances
> Marine machinery
> Railway machinery
> Military machinery
Each of the eight machine categories is divided into sub-categories by machine type,
engine type and engine-power class (Fig. 3). The engine-power classes are in some
cases engine-type and category specific. The resulting sub-categories are referred to as
segments. Appendix A2 contains a list of all machine categories and types.

CORINAIR (CORe INventory of AIR emissions) is a joint project of the European Topic Centre on Air Emissions and the European
Environmental Agency (EEA). The objective here is to collect, manage and publish data relating to air emissions with the aid of a
European air emissions inventory and database system.
