Earth Overshoot Day marks the date when humanity’s demand for ecological resources and services in a given year exceeds what Earth can regenerate in that year. Find here tips and useful resources to help you taking steps to #MoveTheDate.

Earth Overshoot Day 2021

Each year, Earth Overshoot Day marks the date when humanity has used all the biological resources that Earth can renew during the entire year. Earth Overshoot Day is hosted and calculated by Global Footprint Network, an international research organization that aims to provide information and solutions to live in the means of the planet.

In 2020, the Earth Overshoot Day landed on 22 August, more than three weeks later than in 2019, as COVID-19 caused humanity’s ecological footprint to contract. Pandemic-related lockdowns, borders’ shutdowns, travel restrictions, curfews, and the like, which have been implemented around the world for the past 12 months, are still having an impact this year. Can you guess the date for 2021?

Explore the open data and hints, take out your calculator and submit your best estimate to the Guess-the-date contest. This contest aims to foster a better understanding of what Earth Overshoot Day is all about and why solutions to push back the date are crucial to achieving sustainability. The date of Earth Overshoot Day 2021, as well as the winner of the contest, will be announced on 5 June.

Switzerland Overshoot Day 2021

Country Overshoot Day reflects the ecological footprint of a country by comparing the population’s demand and the nation’s biocapacity.

Switzerland’s Overshoot Day 2021 falls on 11 May. From this date onwards, Switzerland will be living on credit at the expense of future generations. If the world’s population had the same lifestyle as Swiss citizens, the resources of three planets would be necessary to ensure its existence.
