Earth Day: At school
Celebrating Earth Day at school
-
There are roughly 450,000 public school buses in the United States; 390,000 are powered by diesel fuel.
-
New standards set by EPA will go into effect over the next 2 to 5 years resulting in cleaner bus engines. However, it will take time for these new cleaner buses to replace the existing fleet of public school buses.
-
Children are vulnerable to the effects of diesel emissions which can cause respiratory disease and exacerbate long-term conditions such as asthma. Implementing EPA's Clean School Bus Program will result in substantial health benefits including: fewer cases of lower respiratory symptoms in healthy children; fewer cases of upper respiratory and asthma symptoms in asthmatic children; and fewer cases of acute bronchitis.
-
School buses that leave their engines idling while standing, often very near schools, create indoor as well as outdoor air pollution problems.
-
About 67% (260,000) of the diesel school buses were manufactured between 1990 and 2002. These buses can be made much cleaner by upgrading or retrofitting their existing emission control systems.
-
About 33% (129,000) of all diesel school buses are pre-1990 buses. These buses are the heaviest polluters and are good candidates for early replacement.
