Country Overshoot Days
A country’s overshoot day is the date that Earth Overshoot Day would fall if all of humanity consumed like the people in this country.
A country’s overshoot day is the date on which Earth Overshoot Day would fall if all of humanity consumed like the people in this country.
Let’s take Switzerland, for example, using the latest data available (for 2013):
• The Ecological Footprint in Switzerland is 5.28 gha per person
• Global biocapacity is 1.71 gha per person.
Therefore, it would take (5.28/ 1.71) = 3.1 Earths if everyone lived like the Swiss, OR
we can determine Switzerland’s overshoot day as 365 * (1.71/ 5.28) = 118th day in the year. The 118th day is the 28th of April, the Swiss overshoot day (in 2013).
