Your carbon footprint is the sum of the greenhouse gases your lifestyle emits each year. The big levers are usually flying, driving, home energy, and diet. The global average is about 4.7 tonnes per person, but a livable-planet target is closer to 2 tonnes. Estimates use typical emission factors and will vary by region.

Reading this result: Diet is your single biggest slice at 2.5 t of the 8.7 t total, so that is where a cut moves the needle most — one long-haul flight can outweigh a whole year of driving.
