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:

world biocapacity world ecological footprint × 365 = EOD {\displaystyle {\frac {\text{world biocapacity}}{\text{world ecological footprint}}}\times 365={\text{EOD}}}

In 2020 the calculated overshoot day fell on August 22 (more than three weeks later than 2019) due to coronavirus induced lockdowns around the world.[3] The president of the Global Footprint Network claims that the COVID-19 pandemic by itself is one of the manifestations of “ecological imbalance”.[4]

Earth Overshoot Day is calculated by Global Footprint Network and is a campaign supported by dozens of other nonprofit organizations.[5] Information about Global Footprint Network’s calculations[6] and national Ecological Footprints are available online.[7]


I am Volker Schunck and live in Dresden, Germany. First I was an industrial clerk, then I studied theology. Through my engagement with Zen, I became aware of the Christian mysticism. Meanwhile, I go my own way. For me, faith is not a world-view but a being. It is important to me, not to live lost in thought but aware and intensely. For me, this also includes careful handling of other people. The NVC (Nonviolent Communication), which I learned during my training as a mediator, helps me with this.
