The date is determined by extending the current edition of the National Footprint and Biocapacity Accounts to 2024. These accounts, governed by FoDaFo and produced by York University, track countries’ resource performance since 1961, with the latest four years being estimates. This estimate by Global Footprint Network reveals that this year’s Earth Overshoot Day is one day earlier than last year’s. Most of this change is explained by a slight reduction in carbon emissions that is overcompensated by a lower level of carbon sequestration by the oceans.

Dr. David Lin, Science Director of Global Footprint Network, emphasizes that: The persistence of overshoot, for over half a century, has led to declines in biodiversity, excess greenhouse gases in the atmosphere, and heightened competition for food and energy. Symptoms are becoming more prominent with unusual heat waves, forest fires, droughts, and floods.

This year’s Earth Overshoot Day coincides with the Olympic Games. This is topical as both Earth Overshoot Day and the Olympic Games celebrate human potential, peaceful collaboration, and fair play. The Olympic Games hold many races; Earth Overshoot Day focuses on the biggest and most consequential race of all: to what extent humanity will be able to end overshoot by design rather than disaster.

Even as the global overshoot trend has flattened over the last decade, humanity is falling back in the race. Their position does not match their international intentions, such as the promises for 2030 to a) protect 30% of the biosphere and b) reduce carbon emissions by about 45% worldwide compared to 2010. This carbon reduction alone would require moving Earth Overshoot Day 22 days annually for the next six years.

Yet, plenty of possibilities exist to #MoveTheDate, as shown here. Therefore, Earth Overshoot Day is a call for proactive responses to beat disaster with good decisions, as overshoot will inevitably end. Our choice is how.
