I. Calculating your Annual CO2 Emissions
Calculate your annual CO2 emissions from your use of various types of
energy as
well as products consumed and discarded or recycled. Calculate only
your
personal production (e.q. your portion of the.garbage/electric
bill). Summarize
IN A TABLE and give the total CO2 emissions in lbs. AND
tons.
1. Automobile: 1/(---)mpg x 24 lbs/gal x_____ miles/year = ___lbs CO2
2. Airplane travel: 0.9.lbs/mile x _____miles/year = _____lbs CO2
3. Bus: 0.7 lbs/mile x____ miles/year = _____lbs CO2
4. Garbage (average per capita garbage is 5 lbs/day) : _____lbs/day
x 3 lbs
CO2/lb x 365 days = ____lbs CO2
5. Electricity: _____Kwh per year x 1.7 lbs/Kwh = ____lbs. CO2

II. Analysis/pledge for Reducing Annual CO2 Emissions
Tally the reduction in CO2 you are pledging to do below and then summarize
them
in A SECOND TABLE giving a total in lbs. AND tons. The amount
of CO2 reduction saved per action is in the parentheses following the description.
1. Automobile
1. Eliminate ______miles of car travel (use lbs/mile).
2. Maintain tire pressure (usually about 32 psi) (250 lbs)
or
Maintain tire pressure at maximum pressure shown on tire
(usually about 35 psi) (500 lbs).
3. Tune up once a year (900 lbs).
2. Light bulbs
1. Replace _______incandescent lights with compact fluorescents (typical
CO2 reduction = 180 lbs per light).
2. Replace ______high-watt incandescents with lower-watt incandescents
(each 10-watt reduction typically eliminates 22 lbs. of C02
emissions).
3. Turn off lights when leaving a room all year (120 lbs/room).
3. Recycle
1. Recycle _____aluminum cans (typical CO2 reduction = 34 lbs per
100 cans).
2. Recycle _______glass bottles (typical C02 reduction = 30 lbs. per
100
bottles).
3. Recycle ______pounds of paper ( typical CO2 reduction = 20 lbs. per
100
lbs. )
4. Insulate
1. Wrap a home hot-water heater (typical CO2 reduction = 1,200 lbs.
for
electric heaters; 400 lbs. for gas heaters).
2. Insulate the attic of a house (for a 6-room house, typical CO2
reduction + 1,800 lbs. if oil-heated; 1,390 lbs. if gas heated;
4 430
lbs. if electricity heated/cooled)
5. Reduce garbage by: 0.5 Ib/day (600 #)
6. Reduce Hot-Water Use
1. Wash clothes in cold water (typical CO2 reduction = 250 lbs. per
person with an electric hot-water heater; 110 lbs. with gas).
2. Install a low-flow showerhead (typical CO2 reduction = 225 lbs. per
person with an electric hot-water heater; 99 lbs. with gas).
3. Turn hot-water heattr down 10 degrees ( typical CO2 reduction
= 240
lbs. with an electric heater; 106 lbs. with gas) .
7. Trees
a. Plant ______trees (60 lbs/tree)
b. Plant ______shade trees on the east, south or west side of a house
to
reduce air conditioning (600 lbs/tree).
8. Air Condi tioning ( reduction values are given for a single family
detached
home)
1. Raise thermostat by loF (400 kwh)
2. Shade windows with white drapes, blinds, reflective film or awning
(400 kwh) .
3. Paint roof white (1,200 kwh).
9. Purchases
1. Trade in car for one with more mpg (about 700 lbs for each extra
mpg) .
2. Buy new energy-efficient refrigerator (1,000 lbs)
3. Buy new air conditioner with SEER of 12 instead of 8 (3,700 lbs).
10. Donate money to preserve tropical rainforest
( $100 per acre, 240, 0001bs .per acre -one time reduction only)
.
