|EPS: global warming pathway and NOx-transformation pathway|
|Model 1, global warming pathway|
The characterisation factor is determined by an equivalency method using CO2 as a reference.
The global warming potential for N2O on a 100 years basis is 320 (IPCC 1995).
The global warming pathway specific characterisation factor of CO2 for wood loss is determined in "CO2 impact on wood" to - 1.16E-03 kg wood DS(Dry Substance)/kg CO2. Therefore the characterisation factor of N2O for wood is -320*1.16E-03 = - 0.371 kg wood (DS)/kg N2O.
Model 2, NOx-transformation pathway
The characterisation factor is determined by an equivalency method using NOx as a reference.
In "N2O impact on YOLL", the equivalency factor was determined to 1.35 kg NOx (NO2).
The characterisation factor of NOx for wood is determined in "NOx impact on wood" to -2.74 kg wood /kg NOx. Therefore the characterisation factor of N2O for morbidity is 1.35*(-2.74) = -3.69 kg wood/kg N2O.
Calculation of characterisation factor
The total characterisation factor is thus – (0.371+3.69) = –4.06 kg wood/kg N2O.

|The impact is of global character. The modelled system is therefore global. The temporal system borders are 100 years (1990-2090). The society effected is the one described in IPCC scenario IS92A. (IPCC, 1990).|
