“Why Clean Cars?” – What can we do?

• Learn how to analyze which vehicles emit the most pollution and carbon emissions into the atmosphere

• Learn how to find vehicles that are the most efficient with fossil fuels

• Learn how to shop for what vehicles that are the best for the consumer and the environment in that person’s geographical area

Car Activity:Air Pollution Lesson

Objectives:1.TSWBAT analyze relationship between environmental factors and

community health2.TSWBAT compare fueling efficiency of different model cars to

determine the effect of auto emissions3.TSWBAT evaluate how cars contribute to air pollution

What About Vehicle Emissions?!

• What comes from exhaust:– Carbon Monoxide– Sulfur Oxides– Nitrogen Oxides

• Evaporative Emissions– Car ‘running’ but in park

• Refueling Losses– Fueling during day vs. night

Montgomery County

• North Penn is purchasing ultra-low sulfur diesel fuel & retrofitting a portion of its school bus fleet with oxidation catalysts. – one of the largest school bus fleets in PA – serves 12,000 students – Partners include Pennsylvania DEP

Car Activity Example

This slide is a guide for you to do this activity with TWO cars of your choice.

1997-2011 9/2011 - ???

Year, make and model 1997 Honda Accord LX

2012 Honda Civic LX

Purchase price $21,000 $19,000

Miles per gallon:City / highway / combo

25 / 31 / 2825+31=5656/2=28

28 /39 / 33.528+39=6767/2=33.5

Gallons used per year (based on 15,000 miles per year, combined driving)

15000 / 28 = 535.71

15000 / 33.5 = 447.76

Pounds of CO2produced per year (One gallon of gas burned produces 20 pounds of CO2

535.71 x 20 = 10,714.20

447.76 x 20 = 8955.20

Price of unleaded gas (per gallon) $____/GALLON

$2.89 $2.89

Amount spent on gas for one year (in $) (price x gallons/year based on 15,000 miles per year)

$2.89 x 535.71 = $1548.20

$2.89 x 447.76 = $1294.02

10-year cost of vehicle $1548.20 x 10 = $15,482.00

$1294.02 X 10 = $12,940.20
