WARRENVILLE, Ill. (January 29, 2009) - Navistar (NYSE: NAV) continues to distinguish itself as an industry leader in environmental responsibility by becoming the first Original Equipment Manufacturer (OEM) to receive dual certification by the U.S. Environmental Protection Agency (EPA) for helping to reduce greenhouse gas (GHG) emissions.

Navistar is now a SmartWay Transport Partner, becoming the first OEM with SmartWay-certified tractors to also be certified as a transport partner. The SmartWay Transport Partnership is a voluntary program that recognizes partners for setting and achieving greenhouse gas (GHG) reduction goals in freight transport. The program also helps lower operating costs by reducing fuel surcharges and offers customers EPA-certified, fuel-efficient tractors.

“Navistar is one of the largest commercial truck manufacturers in the world, so we ship tons of freight annually between our facilities,” said Edith Ardiente, vice president of Environmental Affairs at Navistar. “Collaborating with the EPA to set tangible goals to reduce GHG emissions and to offer certified, fuel-efficient trucks is beneficial for the environment, the company and our customers.”

Navistar produces two industry-leading trucks with SmartWay certification. Navistar’s International® LoneStar® and International® ProStar® are both SmartWay-certified trucks, a distinction they received for their superior aerodynamics and fuel economy. While the ProStar is the most fuel-efficient Class 8 tractor on the market, last June the groundbreaking LoneStar became the first classic-styled Class 8 tractor to receive the certification.

To be certified as a transport partner, Navistar volunteered to increase the percentage of freight shipped to and from its facilities by SmartWay-certified shippers to at least 50 percent and to reduce GHG emissions at its freight facilities. 
 

Navistar has already exceeded the first goal with 56 percent of its freight currently shipping the SmartWay. Earlier this year, the company implemented an energy initiative aimed at reducing GHG emissions and simultaneously improving energy efficiencies within its operations.

For decades, Navistar has demonstrated a commitment to clean technologies that benefit the environment and its customers. Navistar was the first OEM to release the smokeless diesel engine and was the first engine manufacturer to gain EPA certification for meeting particulate and hydrocarbon emissions standards – six years ahead of schedule. Navistar was also the first to enter line production of commercial diesel hybrid trucks and school buses. For its ongoing leadership, Navistar was honored with the 2007 Blue Sky Award from WestStart-CALSTART for its contributions to the commercial development of diesel-hybrid technology. This preeminent award is presented each year by WestStart-CALSTART, the nation's leading advanced transportation technology industry organization working to support and accelerate the growth of companies developing clean and energy-efficient transportation technologies.
