Carbon Footprint Estimator
Estimate your carbon footprint from everyday activities like travel and energy use.
Putting a number on your impact
A carbon footprint is the total greenhouse gas your activities produce, and estimating it from things like driving, flying, home energy and diet turns a vague sense of impact into a figure you can act on. This gives a rough estimate from your inputs, so you can see which parts of your life weigh heaviest.
Enter your activities to see an estimated footprint.
Where the big numbers hide
The value of the estimate is spotting where your impact actually concentrates, which is often not where people expect. For many, a single long-haul flight outweighs a year of diligent recycling, and home heating and car travel dwarf smaller choices. That is not a reason to dismiss the small habits, but the biggest reductions come from the biggest sources. Treat the figure as a rough guide for focusing effort where it counts, not a precise audit.
