30 per hour (in the city) against the smog

Published on Dec 31, 2015

For many experts, these are measures difficult to apply. On the other hand a “decalogue,” as she was baptized, the minister of the Environment Gian Luca Galletti – is not a law. It is in fact a plan, agreed upon in the meeting yesterday with the mayors of the large cities and the governors of the Regions to find a solution to the emergency (emergency?) smog. Especially on the wave of the ambitious agreement signed by 195 Countries at Cop21 in Paris, just a few weeks ago.

Over all, the measure that seems to have most affected the public opinion is undoubtedly the proposal – on which should precisely deliberate the individual municipalities to lower the speed limit for vehicles of 20 miles per hour. With the result that in many urban centres, soon you may have to circulate at 30 km/h and not 50. The same goes for the strokes, a suburban jurisdiction of the municipalities where the threshold is set at 90 km/h – down, 70–, and so on. The indication is it is also for the highways, where you could go from 130 to 110. Decisions on which, to tell the truth, there is debate as to years.

This is the first of the three “emergency measures”. The other two are the lowering of the temperatures of two degrees in public and private buildings after seven days of overruns of the limits of the pollutants (but who really controls, maybe apartment to apartment in case of independent systems?) and the discounts for the public transport. Point this, too, is rather controversial. Especially in some cities, such as Rome, where the access to the docks of the metro or the climb on the bus are, in fact, a Far West and the ticket is already paying it in a few. Various commentators are, in fact, wondered what could serve coupons discounted that, as they have done in Turin, Rome and Milan in these days, they will last for 24 hours. The most sensible seem to be the strategies of subscriptions integrated, including railways, bus, metro, bike sharing, car sharing and free parking at interchanges, extra-urban. Not to mention of course, the creation of new bike lanes, the sacrosanct priority lanes for public transport and the areas completely for pedestrians.

On the other hand the results of the two days of alternating signs in Rome, of the three block of the movement in Milan and four in Naples (yet to finish), as well as of comparable measures in many other cities, have not brought the expected results in terms of reduction of the amount of particulate matter in the air for metrocubo. Why is air pollution related to the circulation of the private is only one piece, and not even the most full-bodied, stifling the puzzle of smog, which ranges from industry to agriculture, passing precisely for the heating of buildings.

The prospect from the summit of yesterday are outputs other indications on the medium-term. In addition to the fund of 12 million euros immediately available to administrators in the local public transport. An appropriation for now it is bare, will have to rise up to touch the half a billion in the space of three years to include other areas including the redevelopment of the offices of the Pa and the strengthening of the network of electric charging. For many governors, however, of the billions you'll need at least two. The government responded that in the Stability as soon as approved there are another 500 million for similar measures, which brings the total to about a billion in the three-year period.

Among the other ingredients of the “decalogue” there is no great idea, but measures of good sense, too long neglected: from the reduction of emissions for the so-called “large users,” the longed-for renewal of the park of public transport (but with the utilities in bankruptcy will be a long and complex process) up to the increase of green areas in urban areas through the dissemination of good agricultural practices such as the reduction of the administration of nitrogenous fertilizers.

Curious that you both finally arrived, returning to the theme of mobility, to emphasize the deterrence and repression of the stop out of the way – translated, double and triple files of the wild – and, above all, the synchronization of the traffic lights with the monitoring of the intensity of the traffic. To jump off in the next few months, a new round of incentives for scrapping of vehicles older, polluting, dedicated in particular to the fleets of goods.
