Characterisation Method Information
Characterisation Method Name:
Littering impact on severe nuisance
Date Completed:
Principal Method Name:
EPS: Willingness to pay for cleaning
Method Description:

The characterisation factor is determined by a mechanistic method.


The model is based on an assumed behaviour, where an empty package covering 0.02 m2
is picked up at a cleaning operation by a person, who needs 10 seconds for this.
Assuming a labour cost of 10 EUR/hour, the added willingness to pay for cleaning is thus
around 10/3600*10 = 0.0278 EUR or 0.0278/0.02 = 1.39 EUR/m2 . Using the WTP value of severe nuisance of 1000 EUR/person-year, the nuisance of the package would
correspond to 2.78E-05 person-years or 14.6 minutes of severe nuisance.

Calculation of characterisation factor

2.78E-05 /0.02 = 1.39E-03 person-years/m 2

Methodological Range:
The system is global and the time period is 1990. Most of the effect occurs in densely populated areas.
