Environmental Action Plan
Transcript of Environmental Action Plan
school bus each day. So, they must
be safe, right? Sadly, not so much. Bus Pollution -Ashley Fallen and
Krysta Kellner Our school is dependent on diesel
buses as a main source of transportation
for our students. With thousands of children,
that's a lot of buses. And a lot of pollution!!!! This pollution negatively affects both
students' health as well as the environment. Makes sense right?
Poor Environment =Poor Health Bus exhaust not only goes into the air,
it travels inside. Into our lungs. This pollution causes
severe health effects Asthma Lung Damage Chronic Bronchitis Headaches If the substances in this fuel are harmful to us,
they must be harmful to the environment....
right? Right. Exhaust from school buses contain a variety of
substances that are environmentally harmful. In fact, "Diesel exhaust contains both carbon particulates and 40 chemicals that are classified as 'hazardous air pollutants' under the Clean Air Act." -Oklahoma Department
of Environmental Quality Our school uses diesel fuel.
Which is considered hazardous... Solution? Bus Idleness When a bus is
idle, it is spewing unnecessary pollution in to the environment.
At our school the buses wait outside
the school for 15-60 minutes, the buses running the entire time. Reducing any idle time would lower the amount of produced carbon particles and other toxic
chemicals. Particle Filters The main polluter produced
by bus exhaust is carbon particulates. These stick to the respiratory walls and are also light enough to easily disperse in to the environment and spread long distances. To remedy this issue, filters have been designed that dramatically reduces the number of particles emitted
from the bus. Electric Bus A bus powered by electricity is often
referred to as an ebus. These buses are clean,
efficient, and environmentally friendly. It is especially efficient since energy is returned to the battery system whenever the bus decelerates. These buses produce little to no pollution. They are ideal for repetitive routes and are fast to charge, usually taking only 30 minutes. These buses have began to be adopted by a number of school districts and has shown great results. Hybrid buses have also been used,
and have gained positive results as will with
still releasing less pollutants then regular
diesel school buses. Environmental Problems The emissions from buses produce carbon dioxide, which is one of the green house gasses that trap heat in the atmosphere. Which is leading to global warming. Bio Fuels With carbon dioxide increasing the speed of
global warming, the environment is taking an
extreme toll. Global Warming changes the time each growing season lasts, which is killing a vast amount of crops. With food becoming scarcer, animals will be forced to relocate, to look for new food. Bio Fuel Reviews Medford, New Jersey School District -Began Biofuel use in 1997 "Biodiesel offers the best option to increase our reliance on domestic, renewable fuels while producing significant results in terms of emission reduction. Biodiesel's primary attraction is its ease of integration coupled with the fact it is a technology that is not capital intensive and can be applied to older units as well as today's vehicles." -Joe Biluck, Director of Operations and Technology Olympia, Illinois School District -Began Biofuel use in 2002 "We're thrilled to be using biodiesel - a fuel that can be used in all our diesel vehicles with no engine modifications," said Trent Keller, Transportation Director for the Olympia School District. "because of the size of our district and the fact that our bus engines run 200,000 miles before they are traded in, performance and safety are very important to us. Our buses have been running beautifully with biodiesel." Arlington County, Virginia School District -Began Biofuel use in 2011 "We started using biodiesel in our school buses because we saw an opportunity to kill two birds with one stone: clean the air and use a renewable fuel. We're very pleased with biodiesel so far." -Ric Hiller, chief of the equipment division Bio Fuel is not only a clean alternative to diesel fuel, but also an easy one. A bus that runs on diesel can be converted to run on bio diesel with minimal changes, eliminating the need to buy entirely new, energy efficient buses. This option has worked well since it turns our current pollutant spewing buses in to energy efficient ones with little effort. Bio diesel is organic, and produces a significantly smaller amount of carbon emissions, making it a green energy. It is both healthier and safer then diesel
engines. Bio Fuel is made of ethanol from sugar
crops and starch or oils from
algae and plants. * Electric/Hybrid Bus Reviews Kentucky School District -started hybrid use in 2009 “The hybrid school bus project not only serves as a means to improve efficiency and be environmentally conscious. This project will also provide students with learning opportunities across many subject areas. Teachers can develop lesson plans related to fuel consumption, air quality and transportation costs, bringing real-world knowledge and hands-on experiences into the classroom.” -Terry Holliday Kentucky Education Commissioner Kings Canyon Unified School District -started using ebus in February 2012 "Receiving this eTrans school bus has been the most exciting professional adventure for me in some time. My great staff and district support have made it possible for me to have the fun and enjoyment I am experiencing as the eTrans is launched at Kings Canyon Unified." -John Clements, Director of Transportation Diesel exhaust also causes, smog
(Fog or haze intensified by atmospheric pollution) It produces Acid rain, and brings a raise to climate change. Fine Particles According to Director of Transportation Peter Tunny, our school has 77 buses, each holding a hundred gallons of diesel fuel. That's about 7,700 gallons of diesel fuel each fill-up.When running, each of these buses constantly pumps out toxic exhaust, and only manage 7-8 mpg, which makes a bus need to be refueled pretty often. This exhaust is the source of... Liquid Petroleum
Gas (LPG) Liquid petroleum has become a popular
alternative as diesel has become more and
more expensive at the pump. LPG is a compound
that will vaporize as soon as it is released from it's container, making it a clean-burning fuel. LPG-fueled vehicles can produce significantly lower amounts of some harmful emissions such as carbon dioxide and lower amounts of smog air pollutants. Exhaust gases of LPG motors vehicles contain 2 to 3 times less carbon oxide (CO) and 1.2 times less nitrogen oxide. At the same time, the cost of LPG is about 30 to 50 percent that of petrol. Also, 90% of LPG used in the
U.S. comes from domestic sources. LPG Reviews “There has been a lot of recent industry and media discussion regarding alternative fuels and electric powered vehicles in particular. VACC can see the potential of plug-in vehicles, but they are for the future, especially when you consider re-charging networks and training courses for repairers still need to be addressed. But LPG is for the now. It is viable, environmentally friendly and the technology and infrastructure is proven,”- VACC Executive Director, David Purchase “This program has been a tremendous success. Residents of our city have a keen interest in the environment. Propane is proven to be an exceptional fuel choice – both economically and environmentally.” -Bryan Winchester, Portland Public Schools Assistant Director of Transportation notes With all these negatives associated with bus exhaust,
a solution has to be found. Fine particles are a mixture of solid
and liquids which range in sizes from
2.5 microns to 10 microns
Fine particles not only have health effects
towards people but also harm the
environment as well.
These particles are known for creating haze
Haze reduces visibility, sometimes up to 70
Also the particles that finally settle after being
airborne destroy property, can hurt animals, and
cause lakes and other water sources to have
acidic qualities. Works Cited

In order to be a more environmentally friendly school, and have healthier conditions, it's important that we begin changing our ways to a more greener solution now. With so many buses, the amount of pollution from our school is huge, and so is the outcome if we do not change. All of these pollutants and toxins are being pumped into our air everyday! So let's start to change.
