Use our new Carbon Footprint Calculator to determine how much of an impact your actions have on our planet. What is a footprint? It’s the total amount of greenhouse gases (including carbon dioxide and methane) that are generated by our actions. It’s easy—just answer a few questions!
Afterwards, if you think your footprint is too big, you’ll have the option to learn how you can shrink it by making a few small changes in your daily activities for a period of a week to a month.

What's your carbon footprint?
Answer a few questions about how you get around, power your home, and eat. We'll estimate your yearly carbon footprint and show how it stacks up. Numbers are pre-filled with U.S. averages — change them to match your life.

01 Getting around
Drive an EV or don't drive? Slide miles to 0.
02 Powering your home
Home energy is shared, so we split it across everyone under your roof.
Not sure? 881 is the U.S. household average.
U.S. average is about 47 therms/month.
03 What's on your plate
Red meat and dairy carry the heaviest footprint, so this moves the needle more than people expect.
04 Recycling optional
Where it comes from
How this is figured
Your footprint is built from real emission factors published by the U.S. Environmental Protection Agency and the U.S. Energy Information Administration:
- Driving: 19.6 lbs CO₂ per gallon of gasoline, using your weekly miles and MPG.
- Flying: roughly 1,100 / 2,500 / 5,000 lbs CO₂e per short / medium / long round-trip flight, including the extra warming effect of emissions released at altitude.
- Electricity: 0.83 lbs CO₂ per kWh — the U.S. grid average. Your actual number depends on how clean your local grid is.
- Heating: natural gas 11.7 lbs/therm, heating oil 22.46 lbs/gallon, propane 12.68 lbs/gallon.
- Food: diet estimates from peer-reviewed research on the average annual footprint of different eating patterns.
- Shared home energy is divided by the number of people in your household.
This is an estimate to build awareness, not an audit. Benchmarks: global average ≈ 4.8 tons, U.S. average ≈ 16 tons, and the per-person target to stay within 1.5°C of warming ≈ 2 tons. Sources: EPA Household Carbon Footprint Calculator assumptions; EIA Residential Energy Consumption Survey.
