Developed jointly by the Low Carbon Vehicle Partnership (LowCVP) and the Energy Saving Trust (EST) together with industry stakeholders through funding and support from the DEFRA/DfT Joint Air Quality Unit (JAQU), the just-launched Clean Vehicle Retrofit Accreditation Scheme (CVRAS) aims to provide the backbone of future retrofit funding for vehicle emission control systems.

By providing a single standard for any emission technology to be validated to meet the standards set out in the government’s Clean Air Zone Framework for England, the scheme will enable the existing fleet of urban vehicles (initially buses, but extending rapidly to a wide range of vehicles) to be fitted with proven emission control solutions.
 
Larger vehicles (buses, vans and HGVs) contribute over half of UK national average roadside concentration of nitrogen dioxide, according to Defra's AQ analysis. Next year the Government will publish a comprehensive Clean Air Strategy which will address other sources of air pollution.
 
The Clean Vehicle Retrofit Accreditation Scheme will provide independent evidence that a vehicle retrofit technology will deliver the expected emissions reductions and air quality benefits in real world operation. It will enable drivers, technology manufacturers, businesses and local authorities to be confident that properly verified and accredited technologies provide the appropriate emissions reductions to meet the standards in the government’s Clean Air Zone Framework for England.
 
The initial objectives of the scheme are to develop a set of test protocols (using the existing bus and commercial vehicle technology evaluation schemes as starting points) to accredit retrofit technologies which will deliver on road emission levels equivalent to. Euro VI/6, based on the best available data and representative operating cycles.
 
The retrofit accreditation process will be technology-neutral and designed to allow all potential suppliers of eligible, credible emission reduction technology to apply for accreditation.
 
Technologies already potentially identified and in common use include: SCR (Selective Catalytic Reduction) fitted to exhaust systems, hybrid powertrain systems and engine repowers with gas (LPG or CNG). New technologies will need to provide robust, independent relevant test data of the performance, prior to being considered for CVRAS accreditation.

    FTA urges government to rethink Clean air Zones
    The UK’s Freight Transport Association (FTA) says exempting cars from the proposed Clean Air Zones in five English cities is a missed opportunity to significantly improve air quality and reduce carbon emissions. The Department for Environment, Food and Rural Affairs (Defra) has announced that Birmingham, Leeds, Southampton, Nottingham and Derby would be required to introduce Clean Air Zones to reduce concentrations of nitrogen dioxide by 2020 at the latest.

    A new report prepared by Ricardo for the Low Carbon Vehicle Partnership (LowCVP) to review the air quality impacts arising from the recent rapid increase in the number of low carbon buses in the UK recommends that the legislation needs to consider hybrid technology impacts in the test processes to avoid potential unintended consequences in terms of local emissions. As they mainly operate in urban areas, local emissions from buses are of particular significance. Reviewing worldwide test processes for

    New services and equipment helps cities tackle air quality issues
    With poor urban air quality shortening lives and fines being imposed for breaching pollution limits, authorities are seeking ways to clean up their cities. Poor air quality is topping the agenda for city authorities across the globe. In the UK, for example, a report from the Royal Colleges of Physicians and of Paediatrics and Child Health, concluded that poor outdoor air quality shortens the lives of around 40,000 people a year – principally by undermining the health of people with heart and/or lung prob
