Road vehicle standards for air pollutant emissions were first introduced in Europe in 1970, transforming into the Euro standards in 1992, in an effort to mitigate the associated health risks. The adoption of these standards has resulted in a significant decrease in transport-related pollutant emissions, despite a concurrent overall rise in transport activity. The health benefits of the Euro regulations extend far beyond European borders, with over 80% of global on-road vehicle sales following standards based on European emission limits. The European Commission intends to propose an increase to the stringency of these standards in 2022, with the formal adoption and implementation of Euro 7/VII expected in the coming years.
