We, the members of the "Philadelphia Diesel Difference Initiative," recognize that the greater Philadelphia area has an air pollution problem, as evidenced by measured levels of ground level ozone, fine particulate and air toxics. We realize that emissions from diesel powered buses, trucks, locomotives, construction equipment, and other on and off-road diesel sources are a major contributing factor to this problem, and that these emissions cause lung cancer in humans and aggravate respiratory diseases.

Accordingly, we have undertaken the challenge of reducing the air pollutants that diesel-powered engines emit in the greater Philadelphia area. We have jointly pledged to 1) promote projects and strategies that will reduce emissions from diesel engines in the greater Philadelphia area, 2) increase the availability and use of EPA and CARB verified diesel emission control technologies, 3) encourage idling reduction efforts and technologies, 4) promote the use of emission reducing fuels, and 5) promote practices and habits that reduce diesel fuel consumption.
