Frequently Asked Questions
How do I calculate my carbon footprint?
Carbon footprint is measured in metric tons of CO2 equivalent (CO2e) per year. Add emissions from energy use (electricity and heating), transportation (miles driven times emission factor), diet, and consumption. Average US individual footprint is about 16 metric tons CO2e per year. Use EPA emission factors for accuracy.
What are emissions factors and how are they used?
Emissions factors convert activity data into greenhouse gas emissions. For example, burning one gallon of gasoline emits about 8.887 kg CO2. Electricity emissions vary by grid region from 0.2 to 1.0 kg CO2/kWh. Multiply the activity quantity by the emission factor to get total emissions.
