Carbon footprint

Individual & household calculator

An approximate annual estimate of the greenhouse-gas emissions from your home energy, vehicles, travel and waste, in tonnes of CO₂-equivalent.

Where you live and who is included

Location decides which electricity factor applies. Household size lets us show a per-person figure.

For other countries, home electricity can’t be calculated yet and will be listed as not included. Fuels, travel and waste use U.S. EPA factors as an approximation.

Electricity emissions depend on how power is generated in your region. Find your subregion by ZIP code with the EPA Power Profiler.

Enter 1 if you are calculating only for yourself. Use your whole household’s bills if more than one.

This tool runs entirely in your browser: nothing you enter is sent or stored. Results are preliminary estimates for information, not a verified, certified or audited inventory. Methodology and sources.
