(Adnkronos) - “Abbiamo stimato che una decina di miliardi di euro all'anno di investimenti nelle città - circa 270 miliardi di euro al 2050 - ci può consentire di ridurre del 52% le emissioni di CO2 nelle città, seppur siano in crescita”. Così, l’amministratore delegato di A2a Renato Mazzoncini, intervenuto a margine del Position Paper “Sostenibilità urbana. Decarbonizzazione, elettrificazione e innovazione: opportunità e soluzioni per città future-fit” realizzato da TEHA Group in collaborazione con A2A e il contributo scientifico di ASviS, presentato oggi, nell’ambito della 50° edizione del Forum di Cernobbio, intitolata “Lo scenario di oggi e di domani per le strategie competitive”.

00:00The cities in Italy, thanks to our study, occupy 7% of the territory, 30% of the population lives there and produces 60% of the national GDP, but only 29% of the energy is consumed.
00:21This is a demonstration of the fact that they have scale economies, which we have called density economies, which make that even though they are a place of growth, and therefore the CO2 that is produced in the cities also grows, in reality they are intrinsically efficient and therefore they are allies with respect to the theme of sustainability.
00:40So we are working on these economies of density, so an electric grid for example in a city is 5 times more efficient than a rural grid, a water grid 3.5 times more efficient, heating an apartment in a city costs 20-25% less than in a rural area.
01:05So we have to work on this because the challenge of decarbonization in 2050 is still quite complex to achieve.
01:13We have estimated that 10 billion euros per year of investment in the cities, around 270 billion in 2050, can allow us to reduce CO2 emissions by 52% in the cities, even though the cities are growing.
01:28This is perhaps the true fundamental fact, we have to work a lot on the parameters that we know, what we already have in the toolbox, the heating, the heat pumps, the public lighting, the photovoltaic on the roofs, the trees in the cities and all the things that contribute both to sustainability and to the quality of life of people, which remains obviously one of the fundamental goals.
