Help with Carbon Calculation

1. How many people live in your household?
2. What is your household's average monthly gas bill?
3. What is your household's average monthly electric bill?
4. What is your household's average monthly fuel oil bill?
5. How many miles per week do you drive?
6. How many miles does your vehicle get per gallon?
7. How many hours per year do you spend flying?

Each of the above activities contributes to CO2 emissions. The more electricity you use, the more CO2 a power plant will emit to create that energy, though the actual amount emitted depends on how the electricity is generated. The more you drive and the lower you car's fuel economy, the more CO2 you will emit on the roadways. The emissions from airplanes are acutely damaging to the atmostphere since they happen at high altitude.
