ABOUT  EARTH  OVERSHOOT  DAY

Earth Overshoot Day

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.

How Earth Overshoot Day(EOD) is calculated?

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(EOD) 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

(Planet’s Biocapacity / Humanity’s Ecological Footprint) x 365 = Earth Overshoot Day

At the global level, ecological deficit and overshoot are the same, since there is no net import of resources to the planet.

Effects of ecological overspending

Advocates for Earth Overshoot Day note that the costs of ecological overspending are becoming more evident over time. Climate change is the most obvious result and widespread effects. Other cited effects include: shrinking forests, species loss, fisheries collapse, higher commodity prices and civil unrest
