Low Emission Buses

The Low Emission Bus scheme was a competition run by the Office of Low Emission Vehicles (OLEV) to help reduce greenhouse gas (GHG) emissions from UK bus fleets and improve air quality. The scheme has closed with one round of funding distributed over the years 2016-2019.
 
The winners of the Low Emission Bus scheme were announced on the 25th July 2016 and can via the .gov website below:
 
As part of the £600m budget available to the Office for Low Emission Vehicles (OLEV), £30m has been allocated to support the purchase of of low and ultra low emission buses and supporting infrastructure by local authorities and transport operators across England and Wales between 2016-2019.
 
The Low Emission Bus (LEB) scheme was unique in its use of the Low Emission Bus certification process, which requires bus technologies to produce at least 15% less Well-to-Wheel (WTW) greenhouse gas emissions compared with an equivalent Euro V diesel bus, and have a Euro VI certified engine or equivlent emissions based on a methodology developed by the LowCVP.
 
To see a list of the bus models that have been accredited as Low Emission Buses, please see our LEB Certificates page where you can download LEB certificates for free.

Primary Objectives

The new Low Emission Bus Scheme has four primary objectives. To:
  1. Increase the uptake of low and ultra-low emission buses in local authority across England and Wales.
  2. Support the improvement in local air quality.
  3. Reduce the impact of road transport on climate change.
  4. Continue to support the UK manufacturing sector and attract investment to the UK.

Key Features

The Low Emission Bus (LEB) scheme differs from the previous Low Carbon Emission Bus (LCEB) accreditation by awarding funding to technologies scaled against the amount of WTW emissions they save (compared to an equivalent Euro 5 diesel bus) once they have passed a minimum 15% savings threshold. Therefore technologies that save more than the minimum threshold will receive more funding.

Another difference is the additional "top up" funding available to technologies that can demonstrate zero emission capability i.e. travel at least 2.5 km of a route without emitting any emissions. This is designed to address air quality issues in town and city centres.
 
Any bus manufacturer still seeking to claim the Bus Service Operators Grant (BSOG) LCEB incentive is advised to test their bus under the new LowCVP UK Bus test cycle and extract the Millbrook London Transport Bus (MLTB) data required for LCEB approval.
 
The LowCVP Low Emission Bus microsite has been created to provide bus operators, manufacturers and local transport authorities with a resource to assess, plan and implement the roll out of low emission buses.

Well-to-Wheel

This is a sum of all the GHG emissions associated with all the energy used in the creation and combustion of a fuel. This incorporates the emissions released when the fuel is extracted from the ‘Well’, through the refinement process to its transportation to the forecourt. These are known as Well-to-Tank (WTT) or indirect emissions.
