In previous articles, we have shown the degree to which diesel technology has cleaned up its act. As of 2010, all large (Type C & D) school buses are required to meet the same emissions standards. From a certification standpoint, clean-diesel emissions are 90 percent cleaner at the tailpipe than they were 10 years ago and just as clean – if not cleaner – than other fuel types. In fact, the benefits of clean diesel are clear when compared to the “hidden” costs associated with other alternative fuels. (more…)
“We are hearing a lot about alternative fuel in the industry right now,” said Caley Edgerly, president and CEO of Thomas Built Buses. “However, instead of focusing on the alternative fuel trends, school districts should be talking about which school bus operates efficiently, is better for the environment and saves money on fuel costs. It’s always great to have options, but when it comes to fuel choice, diesel remains the best fuel option for fleets today.”
Today there is much discussion in the school bus industry about alternative fuels. For many, the consideration of “green” fuels includes propane, compressed natural gas (CNG) and gasoline. Diesel is often excluded or discounted in the discussion of clean fuels.
But today’s diesel technology is not the diesel of 20, 15 or even 10 years ago. Cleaner diesel fuel, advanced engines and effective emissions control make up a new generation of diesel. It’s clean diesel. And it should be part of any serious consideration of alternative fuels for school buses.
Going Green – Making an Informed Choice
When it comes to the question of whether to make the switch to green fuel, there is no one-size-fits-all solution for every school district. It’s always good to have options. But it’s also important to make an informed choice based on a comparison of all the available data, including emissions, fuel economy, power and performance, durability, safety and total cost of ownership.

When it comes to providing safe, reliable buses, a few things typically come to mind. Some people think of seatbelts, emergency doors, or crash rails. Others look for a bus that can provide exceptional driver visibility with wide windows and consistent control panels. But there is one aspect of safety that is often overlooked — sustainability. As you know, not all buses are created equal in terms of design and overall quality. Likewise, some buses are safer for the Earth, and ultimately, the people exposed to their emissions every single day. Thomas Built Buses is committed to providing a greener tomorrow by implementing manufacturing and maintenance policies that protect our air and conserve our resources. Here’s how they do it:(more…)
The Latest Update on the EPA’s Emissions Technologies
For the past several years, we have informed you about the specific EPA emissions path Thomas Built Buses was taking for all buses equipped with diesel engines, namely, SCR-DEF (Diesel Exhaust Fluid) technology. In retrospect, this decision has proven to be the correct decision. School districts operating Thomas Saf-T-Liner C2 buses equipped with SCR-DEF engines are now experiencing the best fuel economy and the lowest cost of operation of any emissions system currently in use.
