When Earth Overshoot Day Would Land if the Entire World Lived Like These Countries

What is Earth Overshoot Day?

• Earth Overshoot Day is the day that humanity’s demand for ecological resources exceeds the resources Earth can regenerate within that year
• Country Overshoot Day marks the date when Earth Overshoot Day would fall if all of humanity lived like a particular country

How It’s Calculated

Here’s an example of how Country Overshoot Day was calculated for Switzerland:

• Switzerland’s ecological footprint: 4.25 global hectares (gha) per person
• Global biocapacity: 1.48 gha per person

Based on these numbers, humanity would need 2.87 Earths (4.25 divided by 1.48) to support itself if everyone lived like the Swiss.
