Characterisation Method Information
Characterisation Method Name:
CO impact on YOLL
Version:
1999
Date Completed:
1999
Principal Method Name:
EPS: global warming pathway
Method Description:
YOLL stands for Year of Lost Life.


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

Equivalency factor GWP100 (Global Warming Potential) for CO is 3. (Houghton et. al, 1990)

The characterisation factor for CO2 in relation to YOLL is 7.93E07 YOLL/kg CO2.
The characterisation factor for CO in relation to YOLL is therefore 3*7.93E07 =2.38E06 YOLL/kg CO.

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