Earth Overshoot Day 2022 lands on July 28! We are now consuming the equivalent of 1.75 Earth's resources annually!

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. In the UK this date is even earlier and fell on May 19th. In effect we are now consuming the equivalent of 1.75 Earth's annually in terms of natural resources - a threat to our way of life and very existence. More alarmingly, this balance or equilibrium and now marked decline in our Earth's resources has taken place in just the last 50 years!
