Clean Diesel Technologies, Inc. Accredited for London's Low Emission Zone

/ Source: GlobeNewswire

VENTURA, Calif., March 16, 2011 (GLOBE NEWSWIRE) -- Clean Diesel Technologies, Inc. (Nasdaq:CDTI) ("Clean Diesel"), a cleantech emissions reduction company, announced today that following ISO9001 certification at its newly formed UK subsidiary, it has been named by Transport for London (TfL) as an accredited supplier of approved diesel emission reduction systems that could ensure vehicles are compliant with the London Low Emission Zone (LEZ).

The London LEZ, which covers most of Greater London, was introduced in 2008 to encourage the most polluting diesel vehicles to become cleaner in order to improve the health and quality of life for people visiting, working or living in London.

The London LEZ will be subject to two significant changes in January 2012. The first change will affect Heavy Goods Vehicles (HGV), buses and coaches that, from January 3, 2012, will be required to meet more stringent Euro IV emissions standards for particulate matter (PM) to drive within Greater London free of charge. In addition, larger vans, minibuses and other specialized diesel vehicles will be included in the LEZ for the first time beginning January 3, 2012. These vehicles will have to meet a Euro III standard for PM in order to drive within the LEZ free of charge. 

Approximately 150,000 vehicles will be affected by the new regulations. Clean Diesel believes that approximately 20,000 of these vehicles will require diesel emission retrofit solutions.

Clean Diesel has begun to receive orders as a result of the changes to the London LEZ, including repeat business from satisfied customers from 2008, during which Clean Diesel believes it was the second largest supplier having earned a market share of approximately 14%. With its experience, broad range of products and an established distribution channel, Clean Diesel considers itself to be well positioned to deliver reliable and cost-effective solutions to help customers comply with the changes to the London LEZ. Given the compliance deadline imposed by TfL of January 2012, Clean Diesel anticipates that most of the retrofit activity will take place in the second half of 2011.

Charles F. Call, Chief Executive Officer, commented, "The Greater London Authority continues to take a strong position towards improving air quality and we are pleased that TfL has accredited Clean Diesel as a supplier of emission reduction solutions to help reduce pollution in Greater London. Our recent business combination with Catalytic Solutions has enabled us to offer new, more innovative emission reduction solutions utilizing technologies from both companies. The UK ISO9001 certification adds to our existing ISO-certified global manufacturing operations, which underscores our world-class development and manufacturing capabilities. We believe that the anticipated growth of LEZ initiatives in Europe and Asia provides an opportunity for Clean Diesel to market and sell its emission reduction systems."
