Euro 7 is the next generation of European vehicle emissions rules, adopted as Regulation (EU) 2024/1257, and it is a bigger change than the name suggests. Previous Euro standards were about what comes out of the exhaust pipe. Euro 7 covers exhaust emissions, brake particle emissions, tyre abrasion and battery durability in a single legal act - the first time the non-exhaust pollution of road vehicles has been regulated this way.
The Council adopted the regulation on 12 April 2024 as the last step in the legislative process. The text covers cars, vans and heavy-duty vehicles together and aims to lower air pollutant emissions from exhaust fumes and brakes, while establishing stricter lifetime requirements for all vehicles.
The scope is deliberately wide. It applies to vehicle categories M1, M2, M3, N1, N2 and N3 - the full span from cars to the heaviest lorries - plus trailers of categories O3 and O4, and to systems, components and separate technical units, including C1, C2 and C3 class tyres. Brake systems, tyres, traction batteries and replacement pollution control components all fall inside the type-approval net, not just complete vehicles.
For cars and vans, Euro 7 keeps the existing Euro 6 exhaust emission limits but tightens particle requirements. For heavy-duty buses and lorries the bar genuinely rises: more stringent limits for various pollutants, including some not regulated until now - nitrous oxide (N2O) being the headline addition. Particle number limits extend down to PN10 - solid particles of 10 nanometres and above - a tighter measurement than the 23-nanometre threshold used before.
The genuinely new territory is non-exhaust emissions. The regulation introduces limits on brake particle emissions, with specific limits for electric vehicles - a recognition that heavier battery vehicles still produce brake and road-wear pollution even with zero tailpipe output. Tyre abrasion is addressed through a staged approach: if UN-level tyre abrasion limits have not been agreed by set dates (1 July 2026 for C1 class tyres, 1 April 2028 for C2, 1 April 2030 for C3), the Commission will act with its own delegated limits, aiming at the Union’s objective of cutting microplastics released into the environment by 30% by 2030.
For electric vehicles, Euro 7 adds something exhaust rules never needed: minimum performance requirements for battery durability. The reasoning is consumer trust, especially in the second-hand market - traction batteries must retain a good part of their initial capacity after years of use, vehicles must carry state-of-health monitors, and an environmental vehicle passport will record each vehicle’s environmental performance at registration, including battery durability values. For fleets buying electric trucks, this is the beginning of regulated, comparable battery-health data - valuable at resale and for warranty conversations.
Application dates depend on the vehicle type, and they run from the regulation’s entry into force in 2024:
In practical terms the heavy-vehicle industry works to the longer runway: roughly four years for new truck types and five for all new registrations. The staggered design is deliberate - the transition to zero-emission will take longer for heavy-duty vehicles, so their dates are deferred.
Euro 7 is EU law, not UK law - but the truck market is European. Vehicles UK fleets buy in the coming years will be designed to Euro 7 because that is what manufacturers will build, and UK type approval tracks the technical substance of European standards closely. The rules on manipulation devices and strategies - the defeat-device provisions - also sit in this framework, reinforcing the enforcement direction DVSA already pursues at the roadside. And the non-exhaust agenda - brake particles, tyre abrasion, microplastics - is the shape of future urban access and environmental policy everywhere, not only in the EU. Euro 7 is the template; expect its ideas to arrive in UK rules and procurement requirements regardless of the legal route.
Buried in the regulation is a provision with direct operational meaning: detailed rules on manipulation devices and manipulation strategies - designs or software that make a vehicle appear compliant in testing while polluting more in real driving, or that falsify sensor, consumption or battery data. Manufacturers must demonstrate the absence of such devices through vulnerability analysis and tamper protection. For operators already living with roadside AdBlue-cheat checks, this is the same battle fought upstream at type approval: the vehicle of the future will be engineered to resist the emulator, not merely inspected for it.
