As the world gets hotter and more crowded, we don’t need our transportation to continue pumping dirty emissions into the air we breathe. The World Health Association lists air pollution as one of the most threatening global public health issues and estimates that 90 percent of the world’s population now lives in places where air quality exceeds its guideline limits. Fortunately, major cities around the world, like Madrid and Rome, have already begun taking measures aimed at lowering CO2 emissions from cars. The latest to do so is Amsterdam, which passed legislation that will ban cars and motorbikes running on petrol or diesel from driving in the Dutch capital starting 2030. The city council’s plans are a part of a mission to clean up the city’s air pollution, which has been blamed for shortening the life expectancy of Amsterdammers by a year.
