The pandemic has achieved what climate activists and green technology campaigners have not even dared to dream so far: virtually empty city streets, clean air to breath and no airplanes in the skies.
According to the latest data from Berlin, Hamburg and Munich, Germany’s three biggest cities saw their traffic fall by more than a third during the weeks in which lockdown measures were imposed in March, April and May, significantly reducing both rush-hour traffic congestions and CO2 emissions.
With sweeping stay-at-home orders now gradually being relaxed in Germany and elsewhere, authorities all over the world are wondering whether the pre-COVID-19 traffic madness will return to their cities or if there’s an alternative that can make them healthier, greener and a lot smarter than previously.
