Topic of the practice

Within the framework of the Regional Air Quality Plan (PRQA) of the Lombardy Region (Italy) a database named INEMAR (AiR EMission INventory) was developed for the estimation and management of the atmospheric emissions.

Good Practice Information

The INEMAR system considers emissions of about 250 sources (point, area, biogenic, road transport) about 249 SNAP (Selected Nomenclature for Air Pollution) activities are described, the database contains information on 11 different pollutants (SO2, NOx.COV,CH4, CO, CO2, N2O, NH3, PM 2.5, PM10 and PTS), about 33 fuel types are incorporated and the database covers 1546 municipalities. INEMAR organizes all information needed for their estimation: activity indicators, emission factors, other statistical data necessary on spatial and temporal distribution of emissions. As the first Italian experience of an emission inventory source code made by a regional authority, INEMAR is a multi-user database that contains all the data for the emission estimates, the procedures that carry out the algorithms utilized for these estimates and the values of calculated emissions.
The inventory is compiled mainly via a bottom-up approach. A detailed road network , local data on fuel use and local data on industrial activities is used. Activity data are inserted at a provincial level (11 in Lombardy) and then disaggregated to the municipal level through proxy data. For some activities (solvent used in some sectors) only regional or national data are available.

Evidence of success

INEMAR’s strength is the high resolution (municipality level) of all the emission results, great flexibility, and the client-server framework suitable for provincial inventories. The database is accessible by any PC user connected by the regional ISDN network or by Internet, in order to visualize or modify the data in the archive, or for local processing of the data. INEMAR characterized 11 groups of emission sources and is regularly updated using the latest available emission factors and activity data. INEMAR is now used in 8 Italien regions (Lambardia, Piedmonte, Emilia Romagna, Friuli Venezi Giulia, Veneto, Trentino-Alto Adige, Marche and Puglia) and by the provincial offices of ARPA. It covers 1564 municipalities in Lombardia. Data are availalable for download and are used regulary by a multitude of users.
