Carbon Footprint Calculator

Estimate your personal carbon footprint from a credible baseline, then compare common lifestyle changes with actions you can take to green the grid. The goal is to make the scale of different climate choices easier to see, and make it clear that most of your time thinking about climate should be spent on big systematic changes you can make rather than tiny personal cuts. Methodology at the bottom.

These measure the activity's emissions only. The rebound effect means small cuts often don't reduce total emissions — the time or money saved gets spent on something that may emit more.
Grid changes
Estimate your leverage on big problems
Each number is how much carbon would be saved per person working on the problem, calculated as the amount of carbon saved if the action succeeds × the probability of success ÷ the number of people working together on it. All numbers explained in methodology below.

Comparing your cuts

Each personal cut here means one year of that change. So go vegan means one year of veganism.
