Earth Overshoot Day marks the date when humanity’s demand for ecological resources and services in a given year exceeds what Earth can regenerate in that year. We maintain this deficit by liquidating stocks of ecological resources and accumulating waste, primarily carbon dioxide in the atmosphere. Earth Overshoot Day is hosted and calculated by Global Footprint Network, an international research organization that provides decision-makers with a menu of tools to help the human economy operate within Earth’s ecological limits.
To determine the date of Earth Overshoot Day for each year, Global Footprint Network calculates the number of days of that year that Earth’s biocapacity suffices to provide for humanity’s Ecological Footprint. The remainder of the year corresponds to global overshoot. Earth Overshoot Day is computed by dividing the planet’s biocapacity (the amount of ecological resources Earth is able to generate that year), by humanity’s Ecological Footprint (humanity’s demand for that year), and multiplying by 365, the number of days in a year:
(Earth’s Biocapacity / Humanity’s Ecological Footprint) x 365 = Earth Overshoot Day
Earth Overshoot Day 2022 lands on July 28. Learn more about how the 2022 date was calculated.
“The consequences of our ecological overshoot include global deforestation, biodiversity loss, collapse of fish stocks, water scarcity, soil erosion, air pollution, and climate change leading to more frequent extreme weather events such as droughts, floods, and wildfires. These threats in turn bring about tensions and conflicts, and exacerbate global inequalities,” WWF said.
The EU and its member states now have the opportunity to bring their Ecological Footprint in balance with the planet’s biological resources by setting the right priorities and implementing the right policies – such as fully protecting and restoring nature in Europe by 2030 and making the EU climate neutral by 2040, according to WWF.
