Abstract

In the paper the methodology and the software established to evaluate future air pollutant emissions in air qualities management plans are reported. Preliminary a general frame for air quality management planning is introduced and the general concepts of emissions inventores are briefly resumed. The methodology for emissions projections is then discussed and the "driver" and "scenario" concepts are defined. The PREM system, a software model for emissions projections and to evaluate emissions control measures, is presented. Finally a lot of examples from Italy regional case study are discussed. 1 Introduction The following activities are necessary in the frame of the preparation of an Air Quality Management Plan: emissions inventory, use of models to estimate emissions in particular topics (road transport, airports, forests, ports and navigation lines, forest fires), air quality and meteorological data analysis, emissions projection without emissions reduction measures, classification of territory and analysis of priority in remediation actions, planning of measures to reduce emissions, definition of scenarios of reduction, emissions projection in plan scenarios, use of air quality dispersion and photochemical models in the actual situation and in future with and without plan application.
