Why it’s listed
It's run by the Global Footprint Network, an international non-profit founded in 2003 (1). Results are built on its National Footprint and Biocapacity Accounts, with public data and a methods FAQ updated in November 2025 (2).
The trade-off
It uses national averages for the parts you can't answer, and the site loads Google Analytics and a Facebook script.
