CHICAGO, November 27, 2007 - Trading Technologies International, Inc. (TT) and Chicago Climate Futures Exchange (CCFE) today announced that TT has connected its X_TRADER® 7 order-entry platform to CCFE. Founded in 2005 as the world's first environmental derivatives exchange, CCFE, a subsidiary of the Chicago Climate Exchange (CCX), offers standardized and cleared futures and options contracts on emission allowances and other environmental products. TT already connects to the European Climate Exchange (ECX), which was launched by CCX in 2005.

TT's CCFE gateway provides TT customers with direct access to all of CCFE's futures contracts including:

• Sulfur Financial Instrument® futures
• Carbon Financial Instrument® futures

In August 2007, CCFE launched Certified Emission Reduction futures contracts (CERs). A revolutionary derivative product, CERs are the first Kyoto compliant emissions instrument to be used as a hedging tool on a North American exchange. The CCFE is positioning CERs to play an important role in linking the worlds domestic carbon markets and hopes CERs become the international currency standard in the emerging global greenhouse gas reduction markets.
