ÖNORM M 9470

This ÖNORM describes the structure according to which an emission inventory for air pollutants and greenhouse gases is to be compiled. This set of rules is intended to provide a basis for interpreting the results of the emission inventories compiled by the federal provinces according to the same criteria. The compilation of an emission inventory is understood to mean the acquisition, linking, processing and modelling of data so that these can be fed into numerical, textual, graphic or cartographic evaluations by means of automated data processing. Emission inventories serve as an essential basis for the preparation of status surveys according to § 8 IG - L (Immission Control Act - Air) as well as programmes according to § 9a IG - L. They also form the basis for environmental protection programmes. In addition, they form the basis for environmental programmes (establishment of air remediation areas, preparation of clean air programmes and the implementation of evaluations as a result of measures taken), dispersion modelling of immission loads, purposes of spatial planning and regional planning in the environmental field, the preparation of small and large-scale air pollutant transport and emission models, emission reduction concepts and emission estimates for official operating plant licensing procedures and serve as a data pool for climate and energy model regions and climate protection programmes (greenhouse gas reduction programmes) as well as for energy monitoring reports and future strategies of the federal states.
