CSX Announces Commitment to Cut CO2 Emissions by Eight Percent

Emissions Reduction Goal is First-Ever Commitment to EPA from a Major
Transportation Provider

JACKSONVILLE, Fla., June 29 /PRNewswire-FirstCall/ -- CSX today announced a
plan to reduce the CO2 emissions associated with its vast and economically
vital train operations by 8% per revenue ton mile by 2011. The company made
its commitment as part of its participation in the U.S. Environmental
Protection Agency (EPA) Climate Leaders Program, a voluntary program for
businesses to inventory and reduce greenhouse gas emissions.

CSX's commitment to reduce greenhouse gas emissions through the Climate
Leaders Program is the first ever from a major U.S. transportation provider.
CSX's commitment will reduce C02 emissions by 2.4 million tons -- the
equivalent of taking 441,000 cars off the road each year, or burning 5,598,000
fewer barrels of oil.

"Freight rail is the most fuel-efficient and environmentally friendly surface
transportation option. We are pleased to enhance these benefits with our firm
commitment to reduce CSX's carbon footprint," said Michael J. Ward, Chairman,
President and CEO of CSX. "The Climate Leaders Partnership shows that by
working together, business and government can serve our nation's economic
needs while improving our environment."

In CSX's non-railroad operations, the company plans to use building space more
efficiently, improve HVAC systems, and install energy-efficient lighting and
automatic computer-shutdown software.

"As we work to strengthen our nation's infrastructure, stimulate the economy
and compete in a global marketplace, investment in freight railroads will be
critical," said Pennsylvania Governor Edward G. Rendell. "CSX's commitment to
improving the environmental efficiency of its operations will further drive
improvement in what is already one of the most environmentally friendly forms
of surface transportation and strengthen our country's position as a global
leader of a sustainable economy."

Since 1980, the railroad industry has invested more than $1 billion to upgrade
its fleet with more efficient, Tier II clean air locomotives and has improved
locomotive fuel efficiency by over 80%. By the end of 2009, an additional
1,200 CSX locomotives will be upgraded to further reduce emissions and lower
fuel consumption by nearly 10 million gallons. CSX has a long standing
commitment to air quality and clean operations.
