Is Your Bus Exhausting? Stevens Institute of Technology

 

LEARN MORE: Diesel Bus Case Study
Diesel engines emit high levels of nitrogen oxides (NOx), particulate matter (PM), and in addition, a complex mixture of gases, many of which are known or suspected cancer causing agents. Diesel exhaust from idling school buses can accumulate on and around the bus and pose a health risk, particularly to children. When buses idle in the school yard, the exhaust also can pollute the air inside the school building and pose a health risk to children throughout the day. Numerous scientific studies indicate that exposure to diesel exhaust can cause lung damage, respiratory problems, premature death, and lung cancer. However, there are some simple steps that schools can take to reduce idling time and air pollution.

Recommended actions to reduce diesel pollution:
  • Establish the mechanism for continued use ultra low sulfur diesel fuel in the public schools
  • Perform mechanical modification to school buses to enable the use of oxidation catalyst and filter retrofits
  • Evaluate the emission reductions achieved through the project
  • Oversee emissions testing and possible personal monitoring of students in the school district
