Countries must annually report emissions.
Emission inventories must be transparent, consistent,
comparable, complete and accurate.
It is therefore necessary to estimate emissions by applying
models that link activity data to emission factors to calculate net
emissions. Those models should offer the possibility of showing
the effect of mitigation measures.
The knowledge on activity data is still insufficient in many
countries.

Questionnaire assesses relevant parameters in all stages of animal
husbandry systems:
o housing and exercise yard
o grazing
o waste and washing water
o manure storage
o manure application
o animal feeding
o mineral fertiliser application.
Adaptation of the Swiss DYNAMO questionnaire to Austrian conditions.
Farm survey and questionnaire

A representative sample of 5,000 Austrian farms was selected with the
help of Statistics Austria
The survey differentiates three Austrian regions
o Eastern Austria
o Southern Austria
o Western Austria
Farms with animal husbandry play a greater role in the emission
inventory than arable farms and are more often represented in the survey
sample.
