00:00There are two phenomena that I think we should all consider.
00:09The first is that in demographic terms there is a progressive influx of citizens,
00:14that is, of people who at a certain point lived outside the cities and who lived in the city.
00:19This for, I believe, natural reasons.
00:21That is, cities are basically able to produce a level of social and economic efficiency
00:26that the countryside is not able to sustain.
00:30The other fundamental fact is that by using this production system
00:35we are basically, progressively, having problems of climate change.
00:40Climate change is a fact, we see it here today, especially in these days,
00:46and I believe it is another element on which we must oppose contradictions, resistances.
00:53How do these two elements come together?
00:56It is done by being able to make investments and, above all,
00:59by being able to take advantage of the fact that cities are producers of efficiency.
01:03In what sense?
01:04Well, if you think, for example, about heating a condominium
01:07and think about the difficulty of heating houses that are, on the other hand, scattered in a countryside,
01:11you understand very well immediately what the alveolar effect is and what the consequent effect is.
01:16On the other hand, for example, if we are going to reduce the public transport
01:21that still uses endothermic engines and we move it to electric engines,
01:26we have a progressive reduction.
01:28Cities are the natural recipients of those investments,
01:31which we have estimated could be about 270 billion euros by 2050,
01:37which will allow, in fact, to reduce, compared to the trend we had highlighted before,
01:43that is, the increase in the number of people living in cities,
01:46the production that they themselves will have.
01:48How much will it reduce?
01:50So I think it's an important step.
01:53I'll give you an example just to make it clear.
01:55Today there is a lot of talk about the fact that there is the development of artificial intelligence.
01:59Developing artificial intelligence means, for example,
02:02having many data centers that come to Lombardy
02:05and these data centers will also produce a lot of heat.
02:09We can collect that heat by heating the land and directing it towards the cities.
02:13This means that, for example, many homes will automatically become green.
02:17And I think this is an important fact to consider
02:19in order to have and make a strong contribution to the planet.
