«Il lockdown  globale da Covid-19 ha avuto un effetto “estremo” sulle emissioni giornaliere di carbonio, ma è improbabile che duri». Nel 2019, il mondo aveva emesso circa 100 milioni di tonnellate di CO2 al giorno bruciando combustibili fossili e producendo  cemento. All’inizio di aprile 2020 si è scesi a 83 milioni di tonnellate al giorno, con un calo del 17% (intervallo: da –11% a –25%).<\/p>\n

A sostenerlo è il rapporto "Temporary reduction in daily global CO2 emissions during the COVID-19 forced confinement”, pubblicato su Nature Climate Change<\/em>  da un team internazionale di ricercatori guidato da  Corinne Le Quéré della School of environmental sciences dell’università dell’East Anglia.<\/p>\n

Il report mette in evidenza come durante il picco delle misure di confinamento all’inizio di aprile, le emissioni giornaliere sono diminuite del 17% – o 17 milioni di tonnellate di anidride carbonica – a livello globale rispetto ai livelli medi giornalieri nel 2019, scendendo ai livelli osservati l’ultima volta nel 2006.<\/p>\n

Il 7 aprile, sottolineano i ricercatori, durante il picco del  lockdown, le emissioni dei trasporti di superficie, come gli spostamenti in auto, rappresentavano quasi la metà (43%) della riduzione delle emissioni globali. Le emissioni dell’industria e della produzione di energia insieme rappresentavano un ulteriore 43% della riduzione quotidiana globale emissioni. L’aviazione è il settore economico più colpito dal blocco, ma rappresenta solo il 3% delle emissioni globali o il 10% della riduzione delle emissioni durante la pandemia. I ricercatori dicono che «L’aumento dell’utilizzo degli edifici residenziali da parte di persone che lavorano a casa compensa solo marginalmente il calo delle emissioni di altri settori. In singoli Paesi, le emissioni sono diminuite del 26% in media al culmine del loro confinamento».<\/p>\n
