greenarrrowULTRA Low NOx Emissions

Blue Bird's Vision Propane buses now offer a 0.02 NOx emission option!

TextureLowNOxPerfect for districts looking to:

  • make an even bigger impact on air quality
  • take advantage of additional grant incentives like the VW settlement fund
 

93% more Cost Effective

than diesel buses
 

Save up to $3500

per bus annually on fuel & maintenance costs
 

90% Cleaner

with the 0.02 Ultra-Low NOx option when compared to a 2007 or older diesel bus
 

Here are the facts, and how our Ultra-Low emissions can help you:

  • School districts and organizations may qualify for additional funding to modernize their fleets

    • A $2.9 billion Environmental Mitigation Trust from the Volkswagen emissions settlement is being used to fund transportation projects that reduce NOx emissions.

    • Blue Bird school buses equipped with our ultra-low NOx engines may qualify for this funding. Learn more at roushcleantech.com/volkswagen-settlement/.

    • School districts and organizations that deploy propane autogas vehicles may be eligible for federal and state funding and fuel tax credits. The Energy Department’s Alternative Fuels and Advanced Vehicles Data Center provides information and resources at www.afdc.energy.gov/laws/.

  • Blue Bird's Propane buses offer a reliable, safe and cost-effective solution to reduce harmful emissions

    • Almost 1 million students in more than 850 school districts across the U.S. ride to school in propane autogas school buses.

    • One diesel school bus certified at the current standard produces more NOx than 10 Blue Bird Vision Propane buses at the 0.02 NOx level. One diesel bus manufactured before 2007 emits more NOx than 100 Blue Bird Vision Propane buses.

    • Students riding in propane autogas school buses have significantly reduced exposure to NOx and other harmful substances (like soot, carbon monoxide and particulate matter). Children who ride in propane autogas school buses breathe cleaner air every day.

    • In a dollar-for-dollar comparison of Type C school buses, buses fueled by propane autogas reduce NOx the most. Propane autogas buses cost $91 per pound of NOx reduced. Diesel buses cost $1,330 per pound of NOx reduced, making propane autogas 93 percent more cost-effective when it comes to reducing emissions.

  • According to the EPA and other studies , NOx emissions can be harmful to our health and to the environment

    • NOx are regulated under federal air quality standards because they are known to be harmful to human health and to the environment.

    • Exposure to NOx exhaust can trigger health problems, such as asthma, bronchitis and other respiratory issues.

    • In the developing lungs of children, exposure to NOx causes negative health effects, like asthma, which is the leading cause of school absenteeism.

    • Emissions from NOx contribute to acid rain, smog and other air-quality issues.

    • Diesel vehicles emit increased exhaust emissions filled with tiny soot particles and toxic gases.

  • NOx transportation emissions are regulated by our government

    • Nitrogen oxides, known as NOx, are highly reactive gases composed of nitrogen and oxygen. They form when fuel is burned at high temperatures.

    • The primary source of NOx is motor vehicles. According to a University of California Riverside study, diesel-fueled medium- and heavy-duty vehicles are the number one source of NOx emissions in almost every single metropolitan region in the U.S.

    • Approximately 55 percent of man-made NOx emissions come from motor vehicles .

    • NOx emissions are measured through a calculating system known as “grams of pollutants per brake horsepower hour.” This g/bhp-hr provides information on the amount of work of an engine.

    • Over the years, the Environmental Protection Agency has set tougher emissions standards on NOx. Since 2010, the NOx engine standard has been 0.2 g/bhp-hr. In 2007, the NOx standard was 1.2 — or five times dirtier than today’s standard. In 1998, the NOx standard was 4.0 — or 20 times dirtier than today’s standard.

    • Propane autogas is naturally lower in NOx than diesel and gasoline.
