Washington (Platts)--18Mar2008

The US power sector's carbon dioxide production jumped 2.9% in 2007,
compared with 2006, 5.9% compared with 2002's, and 11.7% compared with 1997's,
according to a report issued Tuesday by the Environmental Integrity Project.

The jump is the largest single-year increase since 1998, the
environmental non-profit organization's report found, which only considered
generation located within a state's borders and not power imports.

Ranking at the top in 2007, Texas produced 261.7 million tons of CO2
followed by Ohio at 138.5 million tons. In 2006, Texas also ranked first at
256.1 million tons followed by Ohio again at 135.4 million tons. Florida came
in third in both years at 134.5 million tons.

Despite recently turning away from coal generation as it pursues a
carbon-cutting agenda, California's CO2 emissions have risen from 23.6 million
tons, ranking it the 33rd state in 1997, to 42.4 million tons in 2007, ranking
it 25th. It also ranked fourth in terms of a one-year increase with 4.6
million tons, behind top-ranked Texas at 5.6 million tons.

Looking at CO2 tonnage compared with net generation, the EIP report
ranked North Dakota as the top state in 2006 at 2,328.4 CO2 lbs/MWh, followed
by Wyoming at 2,182.8 CO2 lbs/MWh and Kentucky at 2,070.8 CO2 lb/MWh.
California ranked 45th at 348.5 CO2 lb/MWh, while Texas ranked 24th at 1,278.7
CO2 lb/MWh.
