Characterisation Method Information
Characterisation Method Name:
CO2 impact on Morbidity
Version:
1999
Date Completed:
1999
Principal Method Name:
EPS: starvation pathway and malaria pathway
Method Description:
Model 1, starvation pathway

The characterisation factor is determined by the empirical method.

The indicator value was estimated in Servere morbidity of EPS for CO2, model 1 to 25 million person-years per year.

The characterisation factor for this pathway is:

2.5E+09*1.26E–16 = 3.15E–7 person-years/kg CO2

Model 2, malaria pathway

The characterisation factor is determined by an empirical method.

From Servere morbidity of EPS for CO2, model 2 we get the value of 0.9*30E+06*100 = 2.7×E+09 million person-years

The characterisation factor for this pathway is:

2.7×10 9 *1.26×10 –16 = 3.4×10 –7 person-years/kg CO2

Adding the factors for both pathways we get 3.15E–07 + 3.4E–07 = 6.55E-07 person-years/kg CO2.

Methodological Range:
The impacts are of global character. The modelled system is therefore global. The temporal system borders are 100 years (1990-2090). The society affected is the one described in IPCC scenario IS92A. (IPCC, 1990).
