Public Transit Adopting Clean Diesel Faster Than Other Organizations
Transit Implementing New Technology at a “Surprising” Pace
According to the Diesel Technology Forum (DTF), public transit agencies are upgrading to clean diesel technology faster than the national average for large vehicles. Ezra Finkin, director of policy for DTF, explained that 44 percent of the nation’s transit vehicles meet or exceed the first Environmental Protection Agency clean diesel standard, while 33 percent of the U.S. truck fleet meets that standard.
“The rate of adoption by transit agencies of clean diesel technology surprised us and is very significant,” Finkin said, adding that the public transit sector is “at the forefront” of evaluating which technologies work within a given community’s needs.
Finkin pointed out several components that he says make clean diesel a sustainable energy solution, including high-quality diesel fuel, sophisticated engine design, and exhaust or aftertreatment technology. He said today’s buses have reduced nitrogen and particulate emissions by 98 percent from buses 25 years ago.
The adoption of clean diesel by transit authorities is pressing, as more than 75 percent of the nation’s buses run on diesel, with the vast majority of those buses burning diesel conventionally, rather than relying on hybrid propulsion or biodiesel. Combining those technologies with clean diesel will further reduce emissions and fuel consumption, said Finkin.
“The result is that we expect clean diesel to be the technology of choice for the U.S. public transportation fleet for decades and decades to come,” Finkin said.
