TRC Granted Greenhouse Gas Verification Accreditation

One of the Largest Firms to Earn Designation From California Air Resources Board


LOWELL, MA--(Marketwire - March 7, 2011) - TRC Companies, Inc. (NYSE: TRR) today announced that it is authorized by the California Air Resources Board (ARB) to provide Greenhouse Gas (GHG) verification services under the State's Mandatory GHG Reporting Regulations.

This designation enables TRC to serve the 700 California entities that are required to report their emissions, including power plants, cement facilities and petroleum refineries.

"TRC looks forward to supporting businesses in California achieve compliance with the State's environmental laws," said Chris Vincze, Chairman and Chief Executive Officer. "As the market for GHG and climate change management services grows, TRC is well positioned to serve the more than 10,000 reporting facilities predicted to require these services in the coming years."

You can identify these statements by forward-looking words such as "may," "expects," "plans," "anticipates," "believes," "estimates," or other words of similar import. You should consider statements that contain these words carefully because they discuss TRC's future expectations, contain projections of the Company's future results of operations or of its financial condition, or state other "forward-looking" information. TRC believes that it is important to communicate its future expectations to its investors. However, there may be events in the future that the Company is not able to accurately predict or control and that may cause its actual results to differ materially from the expectations described in its forward-looking statements. Investors are cautioned that all forward-looking statements involve risks and uncertainties, and actual results may differ materially from those discussed as a result of various factors, including, but not limited to, the availability and adequacy of insurance; the uncertainty of our operational and growth strategies; circumstances which could create large cash outflows, such as contract losses, litigation, uncollectible receivables and income tax assessments, including potential payments related to TRC's ongoing IRS audit, if not resolved successfully; regulatory uncertainty; the availability of funding for government projects; the level of demand for TRC's services; product acceptance; industry-wide competitive factors; the ability to continue to attract and retain highly skilled and qualified personnel; and general political or economic conditions.
