TfL certification for Clean Diesel

Transport for London has awarded Clean Diesel Technologies a London Low Emission Zone certificate for its ‘Purifier’ emission control technology


Transport for London (TfL) has awarded Clean Diesel Technologies a London Low Emission Zone (LEZ) certificate for its ‘Purifier’ particulate matter emission control technology.



TfL is responsible for the certification of low emission solutions for London’s LEZ. Clean Diesel’s Purifier met the technical standards of the independent accreditation agencies brought in by TfL to oversee the approval process. The company also demonstrated that it had the technical and commercial capabilities to support the London LEZ programme.



This certification enables Clean Diesel to market Purifier as a retrofit solution to commercial operators which run older vehicles. The filtration system will sufficiently lower emissions from those vehicles so they meet the regulatory standards required to enter the forthcoming London LEZ. TfL plans a daily £200 charge for non-compliance.



Clean Diesel has received initial orders for its LEZ solutions and appointed licensed installers throughout the UK to distribute and install Purifier.



Similar city-based LEZs are planned throughout Europe and Asia where it is recognised that the approval process for London will be one of the standards on which these other LEZs will be based.



Clean Diesel is a global supplier innovative technologies and solutions that reduce emissions, conserve fuel and improve engine performance. Its range of Purifier solutions controls harmful emissions from diesel-powered engines through diesel particulate filtration and reduction systems, while also operating more cost-effectively.
