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.


Reduce your ecological footprint

Calculate your ecological footprint

The Footprint Calculator computes for an individual how many planets would be needed if everyone on Earth had the same lifestyle than this individual. In order to do so, it calculates how much biologically productive area is needed to produce the resources for the human population and to absorb its carbon dioxide emissions.

Steps to #MoveTheDate

The Global Footprint Network invites you to explore steps you can take to help move the date of Earth Overshoot Day and create a sustainable future.

Geneva, a sustainable city: what can you do?

The City of Geneva offers suggestions of daily gestures and personal actions that can help reduce the environmental and social impact of all our activities.


The Biovision Foundation has created the platform CLEVER where consumers can evaluate the sustainability of everyday consumer products and find advice to have a responsible consumption.


The YUKA application created in France in 2017 and available in other countries including Switzerland, aims at informing consumers on the content of food and cosmetic products and guiding them towards a healthier consumption. It can help consumers to use less resources as it provides them with incentives to think about their consumption habits.

This application, available in Switzerland, gives consumers eco-tips to have a responsible consumption. For example, it gives advice on how to buy seafood, fruits and vegetables, souvenirs, and information on labels, among other things.

Labelinfo is a platform of the Pusch Foundation, allowing consumers to learn more on labels. Since 2015, it regroups information on the management, the environmental and social aspects, the processes and the controls of the major labels of the food sector.

The Anatomy of Action

The Anatomy of Action, developed by UNEP and UnSchool, aims to define and communicate the most positively impactful actions anyone of us can take to contribute to a sustainable world. The 15 days challenge will give you ideas on what actions you can take.
