Wrightbus explains what a low-emission vehicle is — and why it is not a zero-emission vehicle
A low-emission vehicle produces lower emissions than an appropriate conventional baseline under the relevant assessment method, and Wrightbus says it should not be treated as synonymous with a zero-emission vehicle.

What Happened
A low-emission vehicle is defined by comparison rather than by an absolute figure. Wrightbus says it produces lower emissions than an appropriate conventional baseline under the relevant assessment method. That makes the label dependent on which baseline and which assessment method are being applied. Wrightbus adds that a low-emission vehicle should not be treated as synonymous with a zero-emission vehicle.
- Produces lower emissions than an appropriate conventional baseline under the relevant assessment method
- A separate category that Wrightbus says should not be treated as synonymous with a low-emission vehicle
Wrightbus says it has been at the forefront of transport innovation since 1946, with a stated commitment to quality, style and safety. Its definition of a low-emission vehicle sits alongside the zero-emission category rather than replacing it. The company does not attach specific emissions figures or named vehicle examples to the definition, leaving the comparison to the assessment method being applied.
Previously from Wrightbus
Wrightbus marked its 80th anniversary in June 2026, describing itself as one of the UK's leading bus manufacturers and calling on the public to help rebuild its lost historical archive. That milestone aligns with the company's statement that it has been innovating in transport since 1946.

Why this matters
Wrightbus is drawing a clear line between vehicles that cut emissions relative to a conventional baseline and those that are zero-emission. Because the label depends on which baseline and which assessment method are used, the term is relative rather than absolute, so anyone comparing vehicles needs to know what they are being measured against. The company warns that treating the two categories as interchangeable misstates what each one means.
