Ridurre velocità


100km/h instead of 130 km/h = 87 trees

Often you go fast on the highway out of habit, without a real reason, but that’s expensive for us and for the planet. Go on the highway at 100km/h (62 mph) instead of 130 km/h (81mph) allows you to avoid the emission of nearly 900kg of CO2 per year (assuming 10,000 km per year). Equivalent to planting 87 trees.

Use the cruise control in your car and set it to 100Km/h: you’re more comfortable, safer, more relaxed and you’ll not risk fines.
When you drive in the city avoid continuous accelerating and braking, also because traffic lights are tuned to less than 40km/h.

The speed has a major influence on consumption and thus on CO2 emissions.

Consumption increases exponentially with speed. This means that if we increase the speed by 30% consumption will increase by 40% or more.

Reducing the speed is therefore one of the most effective ways to reduce CO2 emissions. Sometimes you go fast not because of a real hurry but simply because you’ve always done so and you’ve never thought about pros and cons. And there’re not so many pros… Of course you can arrive earlier, but have you ever tried to calculate how much time you save? Going at 130 km/h (81mph) instead of 100km/h (68mph) for 100km saves 14minuti scarce! Ie 46min against 60 minutes. Other benefits are more difficult to understand: perhaps go faster can be less boring, and our ego can be more satisfied to overcome others rather than be passed by … But it is a poor satisfaction …

But the “cons” of going fast, are a lot more and far more concrete, and not only because of a reduced environmental impact.

The first pro is security: with speed, risks increase exponentially, and the speed is still the leading cause of accidents.

Then there is consumption, and related costs, which, as mentioned, increase more than proportionally to the speed. Means that going from 100km/h to 130km/h fuel consumption increases by almost 40% while the speed of only 30%. Go 130km/h instead of 100km/h saves us 14 minutes on 100km, but involves 4 euro spending more. If in a year you do 15.000km on the highway, the annual savings is up to 600 €!

So before going fast next time think to what it’s more important for you, and take a decision on consequence!!!!
