The Issue

Until electric cars become commonplace, vehicles with internal combustion engines will remain a major contributor to air pollution. The UN predicts that some 70% of the world’s population will live in cities by 2050, up from around 56% today. More urbanization means more traffic in urban areas, more air pollution and a negative impact on air quality, health and the climate. At the same time there’s growing pressure from civil society to reduce air pollutants, often through clean air campaigns.  As a result, policymakers are searching for ways to reduce our exposure to car emissions.
