D7E Award

Innovative D7E Delivers EPA Award

Caterpillar® Receives United States Environmental Protection Agency's Clean Air Excellence Award

The Caterpillar D7E electric drive track-type tractor was recently recognized by the Environmental Protection Agency (EPA) for its emission reductions, efficiency gains and overall innovative technology. Caterpillar Inc. has been awarded the EPA's Clean Air Excellence Award for its innovative electric drive track-type tractor. The electric drive system is the first of its kind in this application, designed to maximize efficiency and productivity while conserving natural resources, and an introductory D7E model was tested here in Nevada at the Republic Services Apex landfill.

The diesel-electric drive technology uses a diesel engine to drive an electric generator that powers two AC electric drive motors. The D7E track-type tractor (bulldozer) increases dozing efficiency by 25 percent, reduces fuel consumption by 10 to 30 percent, and reduces criteria and greenhouse gas emissions. The total emissions reductions, from productivity increase and fuel savings, per hour are: 10% for CO, 20% for NOx and HC, 51% for PM and 23% for CO2.

"Caterpillar is committed to improving the sustainability of our customers, our industry and our shared environment," said Tana Utley, Caterpillar's Chief Technology Officer, who accepted the award at a ceremony in Washington, DC. "We are proud of the D7E and the significant improvements in fuel efficiency and productivity it will provide our customers, ultimately helping them cut costs and reduce emissions. This accomplishment proves technology can improve both customer value and sustainability. Technology unleashes the power of "˜and', which makes sustainable progress possible."

The award was established in 2000 at the recommendation of the Clean Air Act Advisory Committee. It annually recognizes and honors outstanding innovative efforts to help make progress in achieving cleaner air. Award-winning entries must directly or indirectly reduce pollutant emissions, demonstrate innovation, offer sustainable outcomes and provide a model for others to follow.

"Each year, our Clean Air Excellence Award winners offer amazing new examples of how we keep our air safe and clean," said EPA Administrator, Lisa Jackson. "This year's award recipients have built on that tradition of innovation to show what is possible in protecting human health and the environment."
