TEACHERS: Diesel Bus Case Study
- research the diesel retrofit program
- prepare a 5 - 10 minute persuasive argument about the project
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
Use the following links and any other materials you can find to prepare a
5 - 10 minute persuasive argument addressing the questions below.
Additionally, you should address the following questions in your persuasive argument
- Are school buses contributors to air quality problems/issues? Why?
- Do school bus emissions harm people?
- Can anything be done to decrease the amount of emissions?
- Is retro-fitting worth the expense?
- How would the expenses be covered if a school district decided to retrofit?
- Are there other alternatives?
Team up with an English teacher to create an evaluation rubric for the argument, or create a joint assignment for the students.
