The transport sector is not the main responsible of air pollution. The nth retry comes from Arpa Lombardia, which has published the results of the study on the variation of emissions of the main pollutants related to the measures taken to contain the coronavirus. “The data from April,” explained the councillor for the Environment and Climate Raffaele Cattaneo, “confirm what we have already stated: compared to a decrease of the traffic that goes over 65%, there has been a reduction in average emissions, although higher than in the previous month, which amounted to about 44% for NOx, 20% for PM10, the primary and 32% for the Co2”. In essence, the lockdown shows that the decline in road transport does not correspond to the same reduction of the pollutants.
The previous. Further confirmations were emerged at the end of April thanks to the processing of Greenpeace on Ispra data, according to which the smog is related not only to the transport sector (the hardest hit from the measures, often impromptu, and without tangible results), as for other productive activities such as intensive farms, and the heating of buildings. Not dissimilar are the findings of our study, published in the June issue, which has taken inspiration from the images provided by the European Space Agency and by the data of Arpa Lazio and Arpa Lombardia: traffic pollution on this no doubt – but it is also undeniable the huge strides made by the industry of the car on the front of sustainability. The steps that now must not be wasted.
Policies are needed multi-sectoral. For the Palazzo Lombardia, therefore, “the traffic is not the main cause of the pollution: the same concentrations of PM10,” continues Cattaneo, “follow mainly the meteorological factors”. For this, the Region intends to focus “on the action of contrast to the pollution of the air,” not only on mobility, but also policies, cross-sectoral act on the factors that are major cause of polluting emissions: from the heating to the biomass to emissions from spills in agriculture”.
The data of Milan. Cattaneo highlights a further aspect: “This second analysis was differentiated for areas within the Lombardy region. The metropolitan area of Milan, that with the increased urbanization and the increased pressure from the transportation sector, the estimated reductions of up to 60% for NOx and up to 40% of the PM10 primary. In urban areas of Brescia and Bergamo, the estimated reductions arrive at 50-55% for NOx and 35% for PM10 the primary. In areas particularly urbanized, the reduction of pollutants is still less than proportional when compared to the huge drop in traffic flow. We continue, therefore, with the policies aimed at the renewal of the worst polluting vehicles”.
