Air quality is a relevant problem in most extended urban areas in Italy, particularly the ones located in the Northern part of the country. This is what emerged from the recent report (“Mal’aria 2019”) published by Legambiente. Although the annual average has improved over the last decade, peaks in concentrations of fine particulate matter and ozone remain high, especially in winter and summer months. In 2018, 55 departmental capitals exceeded their daily limits for fine particulate matter and ozone (fixed at 35 days for PM10 and 25 for ozone).
The process of developing policy generally involves research, analysis, consultation and synthesis of information to produce recommendations. Guidelines can help cities develop and assess their transport policies to address existing and new policy objectives. Research organisations and institutions provide valuable data and analysis to underpin policy recommendations and decisions.
