CV = coefficient of variation with the exception of electricity production and waste treated, which
are expressed as normal standard deviation.

mation taken from databases, Meier (1997) proposed to assume classes of normal
probability distributions with the following CVs:
• For data obtained by stochiometric determination, a CV of 2% needs to
be considered.
• For actual emission measurements or data computable in well-known
process simulation, a CV of 10% is expected.
• For well-defined substances or summed parameters, a CV of 20% can be
assumed.
• For data taken from specific compounds by an elaborated analytical
method, a CV of 30% is expected.
