America's Greenest School Contest Helps Students Learn about Environmental
Advantages of Riding the School Bus

WARRENVILLE, Ill., April 20 /PRNewswire/ -- Schools looking to go green this
earth day will want to consider another color--yellow--thanks to IC Bus and
its program to educate schools about how they can improve the environment
(www.AmericasGreenestSchool.com). The nation's largest school bus manufacturer
has created a Web site for students, teachers and parents about the
eco-friendly benefits of school bus ridership. Students can also submit an
essay about their school's green activities for a chance to win a free hybrid
school bus from IC Bus and $5,000 scholarship.

The contest, announced in January, is open for entry until April 30, 2009.
Essay submissions should describe how a school shows its commitment to going
green, how it teaches its students the value of green living, how it shows
dedication to green transportation or how it embodies the spirit of a greener
planet. With just one week left to enter, Earth Day is the perfect time to log
on and represent your school.

IC Bus created the contest to help raise awareness of activities kids can do
to impact the environment.

"We want students to have an appreciation for how schools impact the
environment and the difference they can make," said David Hillman, IC Bus,
global marketing director. "Transportation is a critical part of that dialogue
when you consider that every school bus in use takes an average of 36 cars off
the road daily."

As the leader in environmentally responsible transportation options, IC Bus,
the first manufacturer of plug-in hybrid school buses, shares these green
facts about yellow buses:
-- According to the American School Bus Council, 17.3 million cars are
taken off the road annually with children riding school buses.
-- 3.1 billion gallons of fuel are saved every year by students riding
school buses.
-- If 10 percent more children rode school buses, another 300 million
gallons of fuel could be saved annually.
-- The daily fuel cost to transport a child to school is $3.68 for a
private vehicle but only $.73 if that child rides a school bus. And,
school buses are eight times safer than private vehicles, according to
the National Highway Traffic Safety Administration.
-- The IC Bus plug-in hybrid school bus achieves up to a 39 percent
reduction in greenhouse gases and up to a 65 percent improvement in
fuel
economy over other buses.
-- The average school bus uses more than 1,700 gallons of fuel annually,
but the IC Bus plug-in hybrid school bus only uses about 600 gallons.

-- If only 10 percent of the buses in the U.S. were IC Bus plug-in
hybrids,
over $200 million in diesel fuel would be saved annually.

Ten America's Greenest School essay contest finalists will be announced May
11, 2009 and the public will then have one week to read the essays and vote at
www.americasgreenestschool.com for its pick to win the title of America's
Greenest School. The winning school will receive a plug-in hybrid school bus
from IC Bus, which has an estimated retail value of $200,000. The student who
submits the winning essay will win a $5,000 scholarship. Sponsoring teachers
may receive $3,000 to use toward educational materials.
