Berlin – Whether Paris or Barcelona – more and more European cities are turning into 30 km / h zones. In Berlin, too, the call for an inner-city limit is getting louder. In addition to safety and health, climate protection is mentioned as a decisive reason for the introduction. But does a speed limit actually have a positive effect on the climate?
With a speed limit on motorways, this question can be answered with a resounding yes. The Federal Environment Agency has calculated that at a speed of 120 km / h, 2.9 million tons of CO2 are saved per year. Even a speed limit of 130 would reduce greenhouse gas emissions by 1.9 million tons. A speed limit on motorways could therefore be an inexpensive and quick method to save CO2 in the transport sector.
