Stamford, CT -  October 21,  2008 - Clean  Diesel Technologies,  Inc.
(NASDAQ:CDTI; XETRA:CDIA; AIM:CDT), the cleantech emissions reduction
company, has  been  named  to the  Connecticut  Technology  Council's
inaugural  UHY  LLP  Tech  Top  40  program,  a  listing  of  the  40
fastest-growing software,  IT,  new  media,  advanced  manufacturing,
energy/telecom/green tech and life sciences companies in Connecticut.
The list of winning  companies was compiled on  the basis of  revenue
growth over the last four years. 

Clean  Diesel  Technologies  CEO,   Dr.  Bernhard  Steiner,   credits
strategic partnerships  and licensing  agreements, growth  in  global
sales, new  technology verifications  and strong  leadership for  the
company's rapid rate  of growth. Revenues  for the company  increased
from $567,000 for the  year ended December 31,  2003 to $4.9  million
for the year ended December 31, 2007. 

Dr. Steiner  said,  "As a  leader  in  the cleantech  space,  we  are
delighted to be  recognized as one  of Connecticut's fastest  growing
companies. With  over  70 million  diesel  engines currently  in  use
worldwide  and  over  15  million  new  engines  going  into  service
annually, solutions like ours will continue to play a growing role in
meeting  increasingly  stringent  emission  regulations  and   carbon
reduction targets.  Our  distinctive  business  model  provides  core
emission reduction technologies to manufacturers of new engines while
also offering  retrofit  solutions  to clean  up  and  make  existing
engines  compliant   with   current   regulations.   Clean   Diesel's
technologies can  reduce  particulate  matter  over  95%,  oxides  of
nitrogen by over 90%, increase fuel efficiency and lower the  climate
change impact  of heavy-duty,  light-duty  and passenger  car  diesel
engines. 

As new engines  continue to get  cleaner, the relative  share of  air
pollution from  old  engines  becomes more  prominent.  In  response,
regulators  are   focusing  attention   on  existing   engines   with
legislation such as California's Off-road Rule, passed in June  2008,
and the creation of low emission zones throughout Europe. 

Dr. Steiner  also notes  that  cleantech is  clearly a  fast  growing
sector despite recent international turmoil in the financial markets.
Clean Diesel's business continues to be driven by global  regulations
to  improve  air   quality  and  expanding   commitments  to   reduce
environmental impact. Recent  spikes in energy  costs and the  rising
concern of  climate  change  also  highlight  the  energy  efficiency
elements inherent  in Clean  Diesel's  solutions. Clean  Diesel  sees
tremendous growth opportunity as  a result and  is proud to  continue
leading  the  way  in  emissions  reduction  to  create  a  healthier
environment.
