Household Carbon Footprint Calculator

The US EPA's online calculator to get a rough “ballpark” estimate of your personal or family’s greenhouse gas emissions and explore the impact of taking various actions to reduce your emissions.

Greenhouse Gas Equivalencies Calculator

Did you ever wonder what reducing carbon dioxide (CO2) emissions by 1 million metric tons means in everyday terms? The US EPA's greenhouse gas equivalencies calculator can help you understand just that, translating abstract measurements into concrete terms you can understand, such as “equivalent to avoiding the carbon dioxide emissions of more than 208,000 cars annually.” This calculator may be useful in communicating your greenhouse gas reduction strategy, reduction targets, or other initiatives aimed at reducing greenhouse gas emissions.

Carbon Footprint Calculator

The Nature Conservancy’s carbon footprint calculator measures your impact on our climate. The calculator estimates how many tons of carbon dioxide and other greenhouse gases your choices create each year.
