Characterisation Method Information
Characterisation Method Name:
CO impact on wood
Version:
1999
Date Completed:
1999
Principal Method Name:
EPS: global warming pathway and fertilisation pathway
Method Description:
Model 1, global warming pathway

The characterisation factor is determined by an equivalency method using CO2 as a reference.

Equivalency factor GWP100 for CO is 3 in terms of global warming. (Houghton et. al, 1990)

The global warming pathway specific characterisation factor for CO2 is -0.00116 kg wood/kg CO2 for the global warming Therefore the characterisation factor for CO will be 3*(-0.00116) = -0.00348 kg wood/kg CO.

Model 2, CO2 fertilisation pathway

The characterisation factor is determined by an equivalency method using CO2 as a reference.

Equivalency factor For CO2 fertilisation an equivalency of 1 is used as almost all CO will be oxidised to CO2 before leaving the atmosphere.

Therefore the characterisation factor for CO will be 1*(-0.0393) = -0.0393 kg wood/kg CO.

The characterisation factor for CO will thus be -0.00348 - 0.0393 = -0.0428 kg wood/kg CO.

Methodological Range:
The impact is of global character. The modelled system is therefore global.
