Impact of the Proposed Euro 7 Regulations on Exhaust Aftertreatment System Design

In November 2022 the European Commission proposed new Euro 7 standards to reduce pollutant emissions from vehicles and improve air quality. Their stated aims were to ensure cleaner vehicles on the road and improved air quality, protecting the health of citizens and the environment. The proposal included measures to ensure that cars, vans, lorries and buses are much cleaner in real driving conditions that better reflect the urban situation where air pollution concerns are the greatest, and that vehicles meet the requirements for longer. It also simplifies the regulations and addresses emissions from brakes and tyres as well as from the tailpipe. Discussions are now underway between the European Parliament, Council and Commission to reach the final Euro 7 agreement.
