scrap or scrap 
A year ago I said goodbye to my red Micra, scrapped after 12 years of life, 200,000 miles driven, 11,800 liters of gasoline consumed, 27 tons and 700 kilograms of CO2 emitted ( Whereas a tree, as I understand it, absorbs 10 kg of CO2 per year in its first year of life, when I bought the car I should have planted 230 trees and keep them for 12 years to offset the emission of carbon dioxide, and this only for the consumption of gasoline, without consider the whole issue related to the cycle of construction and maintenance). In those days traveling on the highway at 130, sometimes 150, the radio on, headlights off, but after a dozen years and many more white hair, my cruise, stood at 100, the radio was broken , the lights always on (a concession to safety and to the detriment of consumption). To scrap the car and buy a new LPG, the government gave me 2500 € or so, if I remember correctly. From an economic point of view a big deal, considering what I should spend more if I had brought up at the end of its life cycle the machine, then it will have to buy another without incentives. But from an environmental point of view? Well, 'I have many doubts. Of course, in Florence, where I go to work every day, now pollute much less, but how much it cost to build my new car in terms of pollution? The less they produce, the better, so if you scrap a car every 10 years or every 15 years, this makes a big difference. The cost of construction and transportation is certainly very high, I do not know whether it is calculated and I could not find anything online, because it People always talk about post-sales issues, but what I do, from an environmental point of view, of a car, say, consuming almost zero, but under construction (engine, body, plastic ...) Double taint of another car a bit 'less savings?
However, now it's done. The Micra is dead in front of the house and I have a bigger car, a Chevrolet Aveo. Larger than the Micra, 1,200 against 1,000 of a cylinder, with air conditioning, the Micra was not, is 12.8 kilometers with a liter of LPG, compared to 17 km per liter of gasoline in my old red. In Florence, I continue to go by car, because it is difficult to sacrifice half an hour or two a day to travel by public transport. But this, as they say, is another story.
