Clean Diesel Technologies reports that it has received a London Low Emission Zone (LEZ) certificate from the UK’s Transport for London (TfL) for its purifier particulate matter emission control technology (Purifier). This certification enables Clean Diesel to market Purifier as a retrofit solution to commercial operators owning older vehicles. Purifier will ensure those vehicles meet the regulatory standards required to enter the forthcoming London LEZ without having to replace their vehicles or pay the daily £200 charge for non-compliance. The aim of the LEZ is to improve air quality in London by deterring the most polluting vehicles from being driven in the area. The vehicles affected are older diesel-engined lorries, buses, coaches, large vans, minibuses and other heavy vehicles that are derived from lorries and vans such as motor caravans and motorised horse boxes. There will be a phased introduction of the scheme from 4 February 2008 through to January 2012. Different vehicles will be affected over time and increasingly tougher emissions standards will apply. Cars, motorcycles and small vans are not included in the low emission zone (LEZ).
