COOL CONGREGATIONS MANUAL CARBON CALCULATOR

Step 1. Gather the Details (for the past 12 months):

First Auto:

make/model/yr/current odometer: __________________________________________

1. Miles driven: _____
2. Mpg (www.fueleconomy.gov): _____

Second Auto:

make/model/yr/current odometer: _______________________________________

3. Miles driven: _____
4. Mpg (www.fueleconomy.gov): _____

Flights:

5. Total miles flown: __________
(www.usatoday.com/travel/flights/miles/calculator.html or http://www.nwa.com/cgibin/wpmiles.cgi)

Electricity:

6. Total kilowatts (KWH) of electricity: __________

Gas, or… (you only use one of these 3 in your home…)

7a. (Gas) Total therms of gas (if mcf, 1mcf x 10.3 = 1therm): __________
7b. (Heating Oil) Total gallons heating oil: __________
7c. (Propane)Total gallons propane: __________

Garbage:

8. Total gallons of garbage/wk: _____

Step 2. Calculate (use #1 through #8 above and circle answers as you go)

Autos: (Miles driven divided by Mpg. Multiply that answer by 22 lbs to get CO2)

#1 divided by #2 = _____ multiplied by 22 lbs*= __________lbs CO2 by first auto
#3 divided by #4 = _____ multiplied by 22 lbs = __________lbs CO2 by second auto

Flights:

#5 multiplied by .9 lbs* = __________ pounds CO2 by flights/yr

Electricity:

#6 multiplied by 1.3 lbs* = __________ pounds CO2 by electricity/yr

Gas, or…

#7a multiplied by 11 lbs* = __________ pounds CO2 by gas/yr
#7b multiplied by 22 lbs* = __________ pounds CO2 by heating oil/yr
#7c multiplied by 13 lbs* = __________ pounds CO2 by propane/yr

Garbage:

#8 multiplied by 100 lbs* = __________ pounds CO2 by garbage/yr

Step 3. (add all totals from step 2)

Your Household’s Carbon Footprint = __________ Total Pounds CO2

* indicates approximate pounds of CO2 released per unit. For example, 22 lbs CO2 per gallon of gasoline, or .9 lbs CO2 per flight mile. CO2 per KWH varies by state. You can review the latest EPA report here.
