Are you a student or educator using our calculator?
If so, please share your experience using the calculator by emailing [email protected]. We are collecting stories for a campaign for phase two of our mobile-friendly version of the calculator, which includes plans for an administrator platform for teachers.

Why are my results on your new calculator different from the previous calculator?
Our former calculator was several years old. Global Footprint Network updates its data and methodology every year. Our new calculator features our latest data and methodology and will be much easier to update each year.

Why can’t I choose my country and language on your new calculator?
The Calculator is currently available in Chinese, English, French, German, Hindi, Italian, Portuguese, and Spanish. To create country-specific calculators, Global Footprint Network works with local partners to gather regional data on resource consumption. Global Footprint Network is inviting corporate, government, and NGO partners to help us add additional cities, countries and languages to our new calculator. Please contact us if you would like more details.

Does data make a difference?
Data is used regularly to make a difference – including in climate governance and policy. Here a overview.
