Navigating brake emissions in a Euro-7 world

The evolution of exhaust emission standards has significantly improved air quality, yet the focus now shifts to non-exhaust sources such as brake and tire wear.

The evolution of exhaust emission standards, particularly in the road transport sector, has significantly impacted air quality over the years. The shift from Euro-1 to Euro-7 standards has notably reduced exhaust particulate matter (PM) emissions, demonstrating a tangible improvement in environmental quality. However, as exhaust emissions decrease, the focus shifts to non-exhaust sources, such as those from brake and tire wear, which are projected to become the dominant contributors to PM pollution by 2030.
