Tomorrow’s Cities: What can be done to improve air quality?

Around 3 million deaths worldwide were linked to outdoor air pollution in 2016, according to the World Health Organization. The European Environment Agency (EEA) says air pollution is the single largest environmental health hazard in Europe, causing around 467,000 premature deaths in Europe in 2013, where the largest contributor to air pollution is traffic. Vehicular particulate matter poses a health risk to about 85 percent of people living in cities, according to the EEA. Automobiles, in particular diesel cars, are the primary source for particulate pollution. Tire particles, stirred up from the streets, also enter our lungs as we breathe. Nitrogen oxide (NOx) emitted from cars harms our respiratory systems, and may cause asthma. Diesel cars emit NOx – on average, even new models release six times as much NOx as gasoline engines.
