Characterisation Method Information
Characterisation Method Name:
CFC-11 impact on crop
Version:
1999
Date Completed:
1999
Principal Method Name:
EPS: global warming pathway
Method Description:
Model for global warming pathway

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

Equivalency factor

The GWP-100 for CFC-11 is 4000 (IPCC, 1994).

Calculation of pathway specific characterisation factor

The characterisation factor of CO2 for crop production capacity was determined to 7.56E–04 kg crop/kg CO2. Thus the global warming pathway specific characterisation
factor of CFC-11 for severe morbidity is 4000*7.56E–04 = 3.02 kg crop/kg CFC-11.

Literature Reference:
IPPC, “The 1994 Report of the Scientific Assessment Working Group of IPCC. Summary for policymakers”, WMO and UNEP, 1994
Methodological Range:
The system borders are the same as for "CFC-11 impact on YOLL", i.e. global and 100 years.
