GNF - Global Footprint Network

Global Footprint Network


The Global Footprint Network is an international think tank promoting and driving sustainable policy decisions in a world of limited resources. Together with its various partners, Global Footprint Network (GFN) coordinates research, develops methodological standards, and provides decision makers with a menu of tools to help the human economy operate within Earth’s ecological limits.


With the Ecological Footprint, the network has set a global standard for measuring global resources allowing to compare human consumption of natural resources with the actual situation. The Earth Overshoot Day marks the day in the year at which people begin to consume more natural resources than the earth can provide and reproduce in one year. In 2015, this was August 13 and in 2016 August, 8. For the year 2017, this day has been calculated to fall on August 2.


The Global Footprint Network was founded in 2003 with the aim to safeguard a sustainable world for all people in which they can live a fulfilled life within natural ecological boundaries. The headquarters of the Global Footprint Network is located in Oakland (USA), with further offices in Switzerland, Belgium and the Philippines.
