How ecological overshoot is shifting economic rules

Overshoot is humanity’s second largest risk in the 21st century. This event will explore the options that we have once we accept our context.

Earth Overshoot Day marks the date when humanity has exhausted nature’s budget for the year. In 2022, Earth Overshoot Day fell on Thursday 28 July.

Human demand on nature can be tracked. Even conservative estimates show that it has exceeded what the biosphere can renew. If this is so, what are the implications? Who are the winners and the losers? What might be the most effective strategies, for businesses, cities, or entire countries? Are these strategies worth their effort? These are the questions the event will explore.


Dr Mathis Wackernagel

Founder and President, Global Footprint Network

Dr Mathis Wackernagel created the footprint concept in the early 1990s (with Bill Rees) to compare human demand against planetary or regional ecosystem regeneration. The carbon footprint portion has become the most popular variant. In 2003, he founded Global Footprint Network, a sustainability think-tank, making planetary constraints relevant to decision-making. Its largest engagement campaign is its annual Earth Overshoot Day. Mathis’s honours include the 2018 World Sustainability Award, the 2015 IAIA Global Environment Award, and the 2012 Blue Planet Prize.
