Its been mentioned in Deutsche Welle and France 24, which are the BBC/NPR equivalents for Germany and France.

Core argument is that 1.75 Earths are needed to sustain humanity. Somehow our ecological footprint is more than the world's 'biocapacity'. Activists are pushing for this 'index' to be used by Govts to measure ecological crisis.

These bastards measure the 'ecological footprint' with a unit called "gha":

  • The Ecological Footprint for Switzerland is 4.35 gha per person (in 2018)

  • Global biocapacity is 1.6 gha per person (in 2018)

  • Therefore, it would take (4.35/ 1.6) = 2.75 Earths if everyone lived like the Swiss

OR

  • We can determine Switzerland’s overshoot day as 365 * (1.6/4.35) = 133rd day in the year. The 133rd day of 2022 is the 13th of May, Switzerland’s Overshoot Day.
