Trailer Bridge highlights environmental differences on EARTH DAY

Jacksonville, FL – April 23, 2007 -- Trailer Bridge, Inc. (NASDAQ: TRBR) today announced that it highlighted its environmental differences on Earth Day in an email to customers with specific reductions in various emissions associated with moving cargo on Trailer Bridge’s vessels. The differences in these emissions are primarily due to the cleaner distillate fuel used by Trailer Bridge compared to the heavy residual fuel typically used in marine vessels.

Based on a study by Dr. James J. Corbett, Associate Professor, College of Marine and Earth Studies, University of Delaware on the emissions characteristics of the carriers serving the Puerto Rico market, cargo moving with Trailer Bridge can be associated with:

64% less carbon dioxide, the greenhouse gas associated with global warming;
90% less particulate matter, the emission tied directly to port area health concerns;
94% less sulfur oxide, an emission associated with respiratory illness, acid rain and smog.

The complete nine page study by Dr. Corbett is available from Trailer Bridge and requests to obtain a copy can be made by phone at (800) 964-4503 or by email at enviro@trailerbridge.com.

“Today environmental factors don’t play a decisive role in a shipper’s decision making process, but that is rapidly changing as we all become more aware of the environment. On this Earth Day, we wanted to highlight to our customers and their customers that actions they have taken for the benefit of their business by utilizing Trailer Bridge also happen to be good for the environment,” said John D. McCown, Chairman and CEO of Trailer Bridge.

Trailer Bridge is the first marine carrier to join the Smartway Transport Partnership, an innovative voluntary collaboration between the U.S. Environmental Protection Agency and the freight industry designed to increase energy efficiency while significantly reducing greenhouse gases and air pollution. Trailer Bridge’s in-place emissions differences are driven by the distillate fuel that tugs routinely use. Self-propelled vessels utilize residual fuel but they can utilize cleaner distillate fuel. The greater awareness of the impact and effect of vessel emissions is behind the recent suggestions that all vessels switch to distillate fuel from residual fuel as the most direct way to decisively address vessel emissions worldwide.

“We and the general public breathe easier due to Trailer Bridge’s geometric and compelling difference in particulate matter and other harmful emissions,” said Mr. McCown. “The striking emissions improvements available from using the cleaner distillate fuel we use are beginning to receive more attention. If all domestic liner operators using residual fuel switched to distillate fuel, more people would breathe easier in Puerto Rico, Hawaii, Alaska and on the mainland. The U.S. flag merchant marine would clearly move to the forefront of environmental leadership in the area of vessel emissions. It is important to remember that in the Jones Act liner trades, all vessel emissions are local and affect American citizens on both ends.”
