FOR IMMEDIATE RELEASE

ADA-ES Terminates Mercury Control Market Development Agreement;
Company to Pursue Vertical Integration

Littleton, CO - December 7, 2006 - ADA-ES, Inc. (NASDAQ:ADES) today
announced that it terminated its Market Development Agreement ("MDA") with
Norit Americas, Inc. ("Norit"), effective December 6, 2006.  Under the MDA,
ADA-ES had been working exclusively with Norit to develop the North American
market for powdered activated carbon injection systems and sorbents for
purposes of reducing mercury emissions from coal-fired boilers.

The Company believes that the termination of the MDA will not have a
material adverse effect on ADA-ES' business or results of operations.

Dr. Mike Durham, President of ADA-ES, stated, "Since ADA is no longer bound
by the exclusivity of the MDA with Norit, we intend to pursue other sourcing
options for activated carbon and injection equipment including, as
previously announced, the Company's vertical integration into the production
of both of these key components of our mercury control technology."
