Abstract

Se per fronteggiare il cambiamento climatico la decarbonizzazione dell’ambiente costruito è indicata come la principale strategia attraverso energie rinnovabili ed efficienza energetica, tuttavia essa non prende in esame il ruolo svolto dall’aumento di superficie costruita e il relativo consumo indiscriminato di materiali e risorse naturali che invece, spostando il quadro di riferimento, dovrebbero essere considerati come la causa principale non solo dei cambiamenti climatici, ma anche della perdita di biodiversità e dell’aumento delle disuguaglianze nel mondo. Il recente riconoscimento dell’importanza del carbonio incorporato ha portato una maggiore attenzione a un diverso approccio finalizzato a ridurre e ridistribuire l’aumento di superficie costruita, basandosi su dati statistici relativi al carbonio, alla superficie edificata e alle diverse tipologie edilizie. Prendendo in esame gli scenari di crescita e utilizzando un approccio creativo sistemico e il concetto di ‘innovability’, il saggio introduce il ruolo della ‘sufficienza’ per ridurre il consumo di nuovo suolo e per rispondere alle esigenze dei nuovi servizi resi possibili dalla digitalizzazione. Se da un lato questo cambiamento trasformativo può ridurre drasticamente le emissioni di carbonio, la perdita di biodiversità e le disuguaglianze, dall’altro pone sfide e opportunità importanti per architetti, progettisti e altri operatori del settore.
