Urban air quality has improved but it is not enough
Air quality has improved over the decade 2006-2016 with regard to the annual concentration of pollutants, although daily limits are often exceeded in big cities. It was revealed by the report MobilitAria, presented on 16 February 2018 in Rome.
The study, carried out by IIA-CNR and the Sustainable Mobility Working Group of Kyoto Club, examined urban air quality and mobility in the fourteen main Italian cities: Bari, Bologna, Cagliari, Catania, Florence, Genoa, Messina, Milan, Naples, Palermo, Reggio Calabria, Rome, Turin and Venice, analyzing values and exceedances of some pollutants, in accordance with the provisions of current legislation, such as atmospheric Particulate Matter and nitrogen dioxide, related to vehicular and non-vehicular traffic.
It emerges that cities still have concentration values and number of daily exceedances beyond the limit, even though an analysis of different mobility indicators, such as limited traffic zones, car e bike sharing, local public transport and vehicles, shows that administrative restrictive measures did have a positive impact on air quality.
“We need structural measures that lead to greener public transport, low environmental impact mobility and a shift towards electric or gas vehicles. It is necessary to have a strategic national plan that involves all the authorities responsible for the control and management of the territory in order to drastically reduce air pollution in our cities”, says Nicola Pirrone, Director of IIA-CNR, “Italy is doing very well in the production of energy from renewable sources but the distribution networks should be improved”.
