But, despite the difference in methodologies and didactic principles, all specialists are inclined to a single opinion. The key to successful education is the portrait of the teacher. How and exactly will […]

Grading State Fleets

The pollution performance of state school buses varies widely depending on fleet age, fuel choice, and investments in retrofits and cleaner fuels. This report analyzes the amount of pollution released from the average state school bus.18 Each state received a letter grade (A, B, C, or D) for modeled tailpipe soot pollution; we also evaluated […]

SCHOOL BUSES AND CHILDREN’S HEALTH

School buses release particulate matter (soot), toxic air contaminants, and smog-forming pollu-tion from the tailpipe and leaky crankcases. While all of today’s school buses pollute, conventional diesel buses—particularly older models—release anywhere from 10 to more than 100 times as much soot as cleaner alternatives available today. Fine soot particles can evade the body’s normal defense […]

POLICY RECOMMENDATIONS

Minimize exposure.The federal government should set a goal of reducing children’s exposure to school bus pollu-tion to the lowest reasonable level. Through the five “rs,” emissions can be reduced 85 percent or more over the next five years. The U.S. Environ-mental Protection Agency’s (EPA) current goal of retrofitting or replacing all school buses by 2010 […]
