Richard Sandor, Chairman of Climate Exchange plc, said: "At  the
operational level, ECX and CCFE have maintained sustained growth and
strong performances, and CCX has had its highest volume day ever.  From
the public policy standpoint, the U.S. House of Representatives Energy
and Commerce Committee, under the leadership of Congressmen Waxman
and Markey have done tremendous heavy lifting to advance workable,
market-based solutions that provide global leadership and grow the
economy.   The American public and public policy have been served well
by the comprehensive debate and will be further served as today's
legislation moves through the next stages of the Congressional process
and improvements and refinements are discussed."

Neil Eckert, CEO of Climate Exchange plc, said: "The business continues
to move at a pace showing continued growth in key areas.  The potential
for U.S. legislation is starting to be reflected in the increased level
of interest in a market that could well be three times the size of the
European cap & trade scheme."
