The Citizen's Climate Convention voted for a very divisive measure to reduce speed on motorways, from 130 to 110 km / h. With 60% of the votes, this is one of the least consensual proposals, which has given rise to long debates. Advocates of 110 km / h defend a drop in air pollution, and claim that the loss of time would be minimal. What is it really ? Europe 1 compared, over 100 km, the journey time and the mass of CO2 caused.
8 minutes difference
Our reporter traveled 100 km on Monday and 100 km back on the A13, which links Paris to Caen. He drove at 130 km / h in one direction, 110 in the other. The two journeys were made under the same conditions: with cruise control, windows closed, and radio on.

Verdict: It took 49 minutes to travel 100 km while driving at 130 km / h, and 57 minutes at 110, 8 minutes more. By driving slower, our reporter saved 1.5 liters of fuel. In terms of pollution, this means 4 kg less CO2. By way of comparison, each French person produces 12 tonnes of CO2 per year.
