FOR IMMEDIATE RELEASE

ADA-ES SHAREHOLDERS APPROVE ISSUANCE OF UP TO 3 MILLION SHARES TO

SUPPORT VERTICAL INTEGRATION IN MERCURY CONTROL MARKET

LITTLETON, CO – June 19, 2007 – ADA-ES, Inc. (NASDAQ:ADES) announced that at today’s Annual Shareholder Meeting, its shareholders approved the “Stock Issuance Plan” for the issuance of up to three million shares of ADA-ES’ common stock, as described in the Company’s Proxy Statement for the meeting.

This Stock Issuance Plan is intended to allow the Company to raise capital to enhance the Company’s position in the emerging mercury control market, by providing the Company with the means to vertically integrate its operations for the production of mercury control chemicals and equipment for ADA-ES’ power plant customers. Plans include the development of one or more “Greenfield” activated carbon manufacturing facilities and possible acquisition of injection equipment fabricator(s), or other projects or ventures intended to provide the Company and its customers with a long-term supply of activated carbon and related equipment. Funds from any stock issuance may also be used for ADA-ES’ general working capital requirements.

Dr. Michael Durham, President of ADA-ES, commented, “The approval of the Stock Issuance Plan gives us the flexibility to fund our strategies for ADA-ES’ vertical integration and shareholder value appreciation. We look forward to reporting on our continued progress.”

The Company filed a shelf registration statement on Form S-3 with the U.S. Securities and Exchange Commission (“SEC”) on May 30, 2007, to register the three million common shares authorized for issuance under the Stock Issuance Plan. The issuance of the shares is contingent upon the SEC declaring the registration statement effective, and terms of any future offerings, including the number of shares to be issued and the price to be received for them, would be established at the time of the offering.

ADA-ES shareholders also approved the re-election of eight Company directors and the 2007 Equity Incentive Plan, as described in the Proxy Statement for the meeting.
