There is now one unified test procedure used by both Transport for London (TfL) and the national Ultra Low Emission Bus (ULEB) accreditation scheme, to streamline market access for manufacturers of clean, low carbon buses.
The use of the same test will enable manufactures to test a vehicle once and for it to be eligible for use in both the London market as well as qualifying for national grant schemes.
The new test applies to all new models. Those that have already achieved LEB or ULEB status will continue to be classed as such.
The new test will be called the UK Bus Cycle (UKBC) and will comprise of the London Bus Cycle (LBC) phase and a rural phase. The LBC section has been developed from the previous Millbrook London Test Bus cycle which has been used by TfL for the past 20 years to compare the emissions performance of different bus technologies.
