Air pollution is a global environmental health problem, especially for those living in urban areas. Not only does it negatively impact our ecosystems, it considerably affects our health. According to the World Health Organization (WHO), around 8 million premature deaths per year are linked to air pollution, more than double of previous estimates.
One of the pollutants with the strongest evidence of health effects is nitrogen dioxide. In the EU, the largest contributor to nitrogen dioxide emissions is the road transport sector, as well as pollution produced from industrial activities, and residential combustion.
