Emergenza smog. I dati aggiornati di Legambiente e le proposte per ridurre le emissioni inquinanti
Aria sempre più inquinata con un bollettino rosso in peggioramento, come dimostrano gli ultimi aggiornamenti di Legambiente. Da gennaio a oggi a Torino salgono a 70 i giorni di superamento di PM10, mentre Milano è arrivata a quota 59 gg. Male anche Pavia (66 gg), Cremona (65 gg di superamento) e Padova (60 gg).
È quanto denuncia Legambiente che ha aggiornato di nuovo i dati di Pm10 ti tengo d’occhio riportando da gennaio a meta ottobre, quelle città che hanno superato il limite di legge dei 35 giorni di sforamento, con una media giornaliera oltre i 50 microgrammi per metro cubo, previsto per le polveri sottili (PM10).
Ma oltre al PM10, la cappa di smog che sta sovrastando la Pianura padana e molte regioni del Nord Italia è composta anche di ossidi di azoto (NOx), la cui fonte principale ancora oggi è costituita dai trasporti stradali e in particolare dalle auto. Da Torino a Milano passando per Roma sono scattati anche i blocchi delle auto Euro4, e i più moderni Euro5 e Euro6.
Azioni mirate ma prese con troppa lentezza e che secondo Legambiente non basteranno a contrastare l’emergenza smog e a ridurre le emissioni inquinanti. Quello che serve è un pacchetto di interventi concreti e coraggiosi che coinvolgano tutte le città d’Italia, a partire dalla messa al bando, tra il 2020 e il 2025, dei motori diesel e dei veicoli più inquinanti dalle metropoli italiane con più di 50 mila abitanti, con standard sempre più elevati da dover rispettare per poter accedere alle aree urbane.
L’addio ai diesel, per Legambiente sarà un processo possibile, lento ma inesorabile, che in questa fase di transizione deve essere accompagnato da altre azioni concrete: è fondamentale mettere in campo politiche tariffarie ad hoc come la road pricing e la ticket pricing per l’ingresso con veicoli a motore nelle aree urbane, sull’esempio dell’Area C di Milano che ha istituito zone a pedaggio urbano.
Quando il livello di inquinamento invernale ed estivo è troppo elevato, occorre imporre limiti di velocità più bassi sulle strade urbane (dove il limite proposto di 30 km/h serve anche ad aumentare la sicurezza della mobilità ciclopedonale) e rivedere la velocità massima consentita anche su quelle extraurbane (70 km/h) e sulle autostrade (110 km/h).
E soprattutto incentivare e potenziare il trasporto pubblico e quello su ferro, dare più spazio alla micromobilità e alle aree ciclopedonali che attraversano nelle diverse direttrici i centri urbani, sostenere una mobilità sostenibile e nuova con nuove risorse.
Sono queste in sintesi le proposte antismog di Legambiente per ridurre le emissioni inquinanti legate alle auto e al traffico. Ciò sarà possibile o è solo utopia?
Per l’associazione ambientalista si tratta di proposte attuabili e che in Europa trovano già un terreno fertile a partire proprio dalla messa al bando dei motori a diesel. La città di Copenaghen, ad esempio, già dal primo gennaio del 2019 dire addio ai motori a diesel per migliorare la qualità dell’aria della metropoli.
L’Italia, invece, è ancora indietro anche se le buone pratiche messe in atto in alcune città italiane lasciano ben sperare. Segnali positivi arrivano ad esempio da Firenze che entro il 2020 chiuderà il centro storico a tutte le auto.
La metropoli fiorentina ha inoltre lanciato il servizio di car sharing solo elettrico, le bici in sharing , i taxi elettrici, e poi c’è il successo della linea Tram Firenze-Scandicci.
