                       CLIMATE EXCHANGE PLC

        Monthly Trading Update for the European Climate Exchange,
the Chicago Climate Exchange and the Chicago Climate Futures Exchange

Climate Exchange plc summarises the trading volumes for the month of
January 2010 for the European Climate Exchange (ECX), the Chicago
Climate Exchange (CCX) and the Chicago Climate Futures Exchange (CCFE).


*   2010 began with strong volumes amid relatively low price volatility.
    Total volumes reached 416m tonnes, up 45% year-on-year and with an
    average daily volume of over 20m tonnes

*   ECX saw its second highest volume month to date in daily futures
    (spot) with an average of 567,000 tonnes per day with an increasing
    market share

*   ECX open interest continues to grow and has reached nearly
    600,000 contracts. Phase 3 EUA trading activity is growing rapidly
    with over 9m tonnes of open positions in the Dec 13 contract, and
    450,000 tonnes in the Dec 14 contract.

*   ICE Futures Europe and ECX welcome their 103rd and 104th Members:
    Macquarie Bank Limited (also a Clearing Member) and Consus S.A.

*   CCFE Open Interest increased 45% over January 2009 although
    aggregate volumes are 16% lower than the same period last year

*   CCFE saw a record trading month in its Renewable Energy
    Certificate (RECs) complex with 1,490 contracts traded, including
    the first trade in its Massachusetts Compliance contracts

*   CCX volumes continue to be hampered by the stalemate on climate
    legislation in the U.S. Senate, and in particular, the limited
    provision of early action credits for corporate reductions and
    offset projects in current draft legislation

*   The U.S. submitted GHG reduction targets of 17% below 2005
    levels by 2020 to the U.N. in accordance with the Copenhagen Accord.
    In his State of the Union address, President Obama renewed his
    commitment to working with the Senate to advance bipartisan support
    for a comprehensive energy and climate bill

Richard Sandor, Executive Chairman of Climate Exchange plc, said: "The
continued lack of political progress and the disappointing outcome of
Copenhagen has obviously affected market sentiment and CCX volumes.
Nonetheless, Washington clearly remains committed to addressing climate
change. In his State of the Union address last week, President Obama
called on Congress to pass 'a comprehensive energy and climate bill
with incentives that will finally make clean energy the profitable kind
of energy in America.' At the same time regulators and investors are
increasingly weighing the risks associated with climate change, as
evidenced by last week's SEC vote on disclosures. These factors,
combined with the growing regional interest in cap and trade programs
in the U.S., bode well for domestic and global carbon markets and
Climate Exchange plc's growth potential."

Neil Eckert, Chief Executive Officer of Climate Exchange plc, said:"ECX
had another month of solid year on year growth. More pleasing is
the continued growth of Open Interest to 600,000 contracts. CCX
volumes continue to be disappointing and are expected to stay that way
until there is political progress. CCFE volumes have been less
severely impacted and once again the Open Interest, up 45% year on
year, is encouraging."
