Not all countries will have an overshoot day. We can determine Swiss Overshoot Day using the equation 365 x (1.6/4.35) = 133, or as the 133 rd day in the year. Therefore, it would take (4.35/ 1.6) = 2.75 Earths to support humanity if everyone on the planet lived like the Swiss. Global biocapacity is 1.6 gha per person (in 2018).The Ecological Footprint of Switzerland is 4.35 global hectares (gha) per person (in 2018).Its 2023 overshoot day is based on the latest (2018) available results from the 2022 edition of the National Footprint and Biocapacity Accounts: Let’s take Swiss Overshoot Day as an example. Additionally, time is needed to assemble the accounts. This is due to a three to four-year lag between the latest data-year and the latest edition year as a result of the UN’s reporting process. The 2022 edition data stretches from 1961 to 2018. In order to meet this publication deadline, the 2023 country overshoot days were calculated in December 2022 using the 2022 edition of the National Footprint and Biocapacity Accounts, which was the latest edition available at the time.
