Ã
ally appealed to compost their yard waste or to dispose of it through one of
the many waste disposal/recycling sites.
The occurrence of bonfires at midsummer night and in general are likewise
not registered, therefore it has not been possible to obtain activity data.
Due to the cold and wet climate conditions in Denmark wild fires very seldom
occurs. Controlled burnings and the occasional wild fires should be included
under Agriculture.

The uncertainty of the number of human cremations is miniscule, however
for the purpose of the calculation it has been set to 1 %.
The uncertainty of the activity data from animal cremations is also minimal
for the most recent years (1998-2010) but is increasing back in time (to 200 %
in 1980). The uncertainty is set to 80 % for all years.
The uncertainty of the total number of accidental fires is very small, but the
division into building and vehicle types and also the calculation of full scale
equivalents might lead to a small uncertainty, partly caused by the category
“other”. The uncertainty for both building and vehicle activity data is therefore
set to 10 %. The uncertainty is lowest for the most recent years. The following
Tables 7.27 lists the uncertainties for activity data in the waste sector.

The uncertainties for emission factors in the waste sector, and at the present
level of available information, are listed in Table 7.28.
