ABSTRACT: This
paper presents the focus on emission estimates in the Italian Regions of the Po-basin obtained by the development of a
common air pollutant emission dataset on the Po-basin and Slovenia foreseen in
the project LIFE PREPAIR (https://www.lifeprepair.eu/). The objective is to update emission
inventories developed by the environmental protection agencies and regions of
Lombardy, Emilia-Romagna, Piedmont, Veneto, Friuli Venezia Giulia, Valle
d’Aosta, the province of Bolzano (participating as stakeholder) and the
province of Trento. A data flux is defined considering the activities on
emission estimates by the different administrations according to the current
Italian legislation. This activity has allowed the completion of two different
datasets on the area for 2013 and 2017. The estimates of primary emissions of
the main atmospheric pollutants have a high spatial resolution defined at the
municipal level. The non-industrial combustion of biomass in small domestic
appliances is the main source of primary PM10 in the Po-basin. NOx primary emissions are determined for quite of a half by road transport. Manure
management and fertilization in the agriculture sector are the sources of NH3.
The ensemble of the collected data shows a very good comparability even if all
local compilers perform independently the estimates, thanks to a good alignment
in using reference methodologies and to projects of common methodological
development, as reported by the INEMAR project (https://www.inemar.eu/). The estimates of PM10, NOx and NH3 are comparable with data reported by the European Environment
Agency EEA for the European Member States EU-28 (until 1 February 2020) and for
Italy, reported under the UNECE Convention on Long-range Transboundary Air
Pollution and European Union National Emission Ceiling Directive.
