Step 1 of 6

Profile & Assessment Setup

Quick estimate

Required. Household-based emissions such as home energy and rubbish are divided by this number to estimate your personal share.

Required. Home type scales the quick home-energy estimate only; use detailed records for a better estimate.

Restores this section to the current country’s default estimate.

Complete the required fields above to continue.

Step 2 of 6

Residential Energy & Utilities

Electricity, heating, water and wastewater are combined into one simple Home category.

Quick home estimate

Required quick inputs: household electricity estimate, renewable electricity share, main heating fuel/use and water use. These are treated as household inputs and divided by household size.

Restores this section to the current country’s default estimate.

kWh

Leave the default if you do not have a bill handy.

%

Household input. Enter 0% for standard grid electricity. Enter 100% only if verified renewable electricity covers the whole household.

Household input. Choose the main fuel used for space heating, if any.

Household input. Pick the closest level for the whole household, not only your own use.

Household input. Includes water supply and wastewater treatment in the estimate.

Complete the required fields above to continue.

Step 3 of 6

Mobility & Aviation

Car use, public transport, taxis and flights are combined into Travel.

Quick travel estimate

Required quick inputs: your main vehicle, your weekly travel distances and your flights per year.

Restores this section to the current country’s default estimate.

Personal input. Select the vehicle you personally use most often. Choose “No private vehicle” if you do not drive or ride.

Personal input. Enter your typical weekly private-vehicle distance. Use 0 if you do not use a private vehicle.

Personal input. Include bus, rail, tram, metro or ferry trips you personally take in a normal week.

Personal input. Include taxi and rideshare distance you personally use; leave 0 if rarely used.

Flights per year

Personal input. Count return trips taken by you personally, not the whole household. Use detailed mode if you know total passenger-kilometres.

Short return trips are local/domestic-style journeys, roughly under 3 hours each way.

Medium return trips are regional journeys, roughly 3 to 6 hours each way.

Long-haul return trips usually cover international or intercontinental journeys, roughly over 6 hours each way.

Complete the required fields above to continue.

Step 4 of 6

Food & Dietary Profile

Quick mode uses diet profiles. Detailed mode can use weekly meal patterns when available.

Quick food estimate

Required quick inputs: your diet type and your food-waste level.

Restores this section to the current country’s default estimate.

Personal input. Choose the closest normal eating pattern for you; detailed mode can refine this using weekly meals.

Personal input. This adjusts your food estimate for avoidable food waste habits.

Complete the required fields above to continue.

Step 5 of 6

Consumption, Goods & Services

Clothing, electronics, household goods, services, recycling and composting are simplified here.

Quick shopping estimate

Personal input. These questions cover your personal purchases of clothing, electronics, household goods and services.

Examples: clothing, shoes, phones, computers, appliances, furniture, homewares, tools, books, toys, sports equipment, haircuts, cleaning, repairs, subscriptions, education, entertainment and professional services.

Restores this section to the current country’s default estimate.

Personal input. Choose your overall purchasing level compared with an average person in your country.

Personal input. Include phones, computers, appliances and other new electronic items bought for your own use.

Personal input. Include new clothing and footwear you buy for yourself.

Waste and recycling

Required quick inputs: household rubbish, recycling and composting. Waste is treated as a household input and divided by household size.

Restores this section to the current country’s default estimate.

Household input. Estimate the whole household’s general rubbish, not only your own share.

Household input. Choose the option that best describes the household’s usual recycling behaviour.

Household input. Composting reduces the waste estimate slightly in this estimate.

    About these benchmarks

    National and world figures are territorial per-capita greenhouse-gas emissions, including land-use change, from Our World in Data. They provide national and global context and are not a like-for-like personal lifestyle average.

    Your result is an educational personal-footprint estimate, not a certified greenhouse-gas inventory. For source details, assumptions and limitations, open Methodology & data.

    The header average uses source-documented national per-capita greenhouse-gas emissions in tCO2e/person/year. If a region/state is selected, the comparison profile is recalculated using that region’s electricity factor and labelled Region-Adjusted Average; this is not a separate official regional statistic. The quick personal estimate stays on the national electricity factor when only the region is changed; detailed electricity or EV records use the selected regional electricity factor.
