Clean Vehicle Retrofit Accreditation Scheme (CVRAS)

The CVRAS work programme will deliver cleaner air in our towns and cities across the UK where air pollution exceedances dictate that action is needed at a local level. This programme targets the cleaning up of older and more polluting legacy vehicles that contribute to NO2 and particulate matter pollution. The UK Government has a legal obligation to meet ambient air quality limits and has set out a clean air strategy that addresses the issue of air pollution, particularly NO2 emissions. By providing a robust assurance scheme for suppliers and their products that can be retrofitted to vehicles will mean vehicle operators can have confidence their vehicles will be recognised as compliant for CAZ, ULEZ or LEZ entry without charge and local authorities implementing clean air policy can be confident in the performance of retrofitted vehicles.
