ExxonMobil Joins U.S. EPA SmartWay Transport(R) Partnership.

FAIRFAX, Va. -- ExxonMobil today announced that it has joined the SmartWay Transport(R) Partnership, a voluntary collaboration between the U.S. Environmental Protection Agency (EPA) and the freight industry designed to increase energy efficiency while significantly reducing emissions that may result in air pollution.

ExxonMobil's participation in the Carrier category will contribute to the Partnership's goal of reducing carbon dioxide, nitrogen oxide and particulate emissions by improving the environmental performance of freight operations. ExxonMobil operates a fleet of 150 company-owned tanker trucks that deliver gasoline products to many of its Exxon- and Mobil-branded service stations across the U.S.

Carrier members of the SmartWay Partnership agree to measure fleet environmental performance using EPA's FLEET -- Freight Logistics Environmental and Energy Tracking -- Performance Model, develop a three-year Action Plan to improve environmental metrics, and provide an annual report on Action Plan progress.

"ExxonMobil is pleased to be the first oil company to join the SmartWay Transport Partnership," said Daniel Mueller, U.S. fleet manager, ExxonMobil Fuels Marketing Company. "This program is a natural fit for the company's emphasis on safety and environmental performance. This program parallels ExxonMobil's own commitment to reduce emissions from its truck fleet, reduce truck fuel consumption, and increase fleet operating efficiencies."

"I am pleased to welcome ExxonMobil Fuels Marketing to the SmartWay Transport Partnership," said Margo T. Oge, Director of the Office of Transportation and Air Quality, EPA. "They are the first petroleum company to join the Partnership in a commitment to increase fuel efficiency and make freight-related environmental improvements."

Launched in February 2004, the SmartWay Transport Partnership aims to achieve fuel savings of up to 150 million barrels of fuel per year. The Partnership brings together major freight shippers, trucking companies, railroads, and logistics companies to pursue mutually beneficial efficiencies that result in emissions reductions and other environmental improvements, as well as cost savings to the companies. The Partnership currently has just over 300 Partners.

Some of the efficiency measures already being implemented by ExxonMobil in its delivery fleet, which are included in the SmartWay Transport Partnership strategies, include:

--driver training

--reduced highway speed

--improved freight logistics

--idle reduction

--single wide tires

--automatic tire inflation systems

--powertrain efficiency

--use of low viscosity lubricants (e.g., Mobil 1 and Mobil Delvac motor oils)

--installing new technologies -- Global Positioning System, on-board computers, stability control

--automatic manual transmissions

--improved aerodynamics.
