Calculated calendar date when humanity's yearly consumption exceeds Earth's replenishment
Progression of the dates of Earth Overshoot Day[1]Evolution of the Earth Overshoot Day dates in time
Earth Overshoot Day (EOD) is the calculated illustrative calendar date on which humanity's resource consumption for the year exceeds Earth’s capacity to regenerate those resources that year. The term "overshoot" represents the level by which human population's demand overshoots the sustainable amount of biological resources regenerated on Earth. When viewed through an economic perspective, the annual EOD represents the day by which the planet's annual regenerative budget is spent, and humanity enters environmental deficit spending. EOD is calculated by dividing the world biocapacity (the amount of natural resources generated by Earth that year), by the world ecological footprint (humanity's consumption of Earth's natural resources for that year), and multiplying by 365 (366 in leap years), the number of days in a year:
Earth Overshoot Day is calculated by Global Footprint Network and is a campaign supported by dozens of other nonprofit organizations.[2] Information about Global Footprint Network's calculations[3] and national Ecological Footprints are available online.[4]
