|Characterisation Method Name:|
|CO2 impact on crop|
|Principal Method Name:|
|EPS: Global warming|
The characterisation factor is determined by an empirical method.
As mentioned in YOLL of EPS for CO2 the decrease in wheat production may be in the order of 5%. Today the global crop production (including wheat, rye, barley, oats, corn, rice, sorghum and potatoes) is 2.4 billion tons. If a 5% decrease is assumed for all crop types by the year 2090 the decrease will be 0.12 billion tons per year. An average over the 100- year period is assumed to be 60 million tonnes per year.
The characterisation factor is thus:
60×E+11*1.26×E–16 = 7.56E–4 kg crop/kg CO2

|The impact is 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).|
