In 2022, Earth Overshoot Day falls on the 28th of July. Earth Overshoot Day marks the date when humanity’s demand for biological resources has surpassed what the Earth can regenerate during the entire year.
In essence, this means that starting on that date and continuing until December 31st, we are in ecological debt to the planet. With five months left, we will already have exceeded the Earth's whole budget.
How Is Earth’s Overshoot Day Worked Out?
Global Footprint Network figures out when Earth Overshoot Day is each year by counting the number of days that Earth's biocapacity would be enough to meet humanity's Ecological Footprint. Global overshoot corresponds to the rest of the year. Calculating Earth Overshoot Day involves multiplying the result by 365, the number of days in a year, and dividing the result by the planet's biocapacity, or the quantity of ecological resources Earth can generate that year.
(Planet’s Biocapacity / Humanity’s Ecological Footprint) x 365 = Earth Overshoot Days
The National Footprint and Biocapacity Accounts calculate the global ecological footprint and biocapacity measurements each year. These accounts use UN statistics and include the most recent information and accounting standards. Ecological Footprint and biocapacity are "nowcasted" to the current year using the most recent data from additional sources, such as the Global Carbon Project, to calculate this year's Earth Overshoot Day.
The last time we were close within the boundaries of the Earth's biocapacity was in the early 70s. (Earliest data available at Global Footprint Network).
We went from living (nearly) sustainably to a state where we have depleted all of the resources within 6 months and 28 days due to deforestation, overfishing, global warming, and biodiversity loss, in less than 50 years.
Unfortunately, even the coronavirus catastrophe was unable to move the date back far enough. Earth Overshoot Day was momentarily delayed in 2020, but it quickly returned to its previous level reached in 2019.
Do All Countries Have An Earth Overshoot Day?
Of course, some nations consume more than others do, and each has its own Earth Overshoot Day, which is the day on which Earth Overshoot Day would fall if everyone in the globe consumed as that nation's citizens do. Overshoot Day this year fell on February 10 in Qatar, December 20 in Jamaica, and May 19 in the UK.
Not every nation will have an overshoot day. A country will only experience an Overshoot Day if its Ecological Footprint per Person exceeds the global biocapacity per Person (1.6 gha). Countries without an Overshoot Daycare are those whose Ecological Footprint per Person is smaller than the global biocapacity per Person (1.6 gha).
Biological resources such as healthy soil, water, and air are critical to human well-being and the survival of our species. Practices that support our planet and humanity's ability to flourish include conservation, restoration, and regenerative approaches.
Cities can sustain fantastic lives with a considerably smaller environmental impact if we make them efficient, bike and pedestrian-centric, and compact. Natural capital supply and demand must be balanced, and city planning and development plans play a critical role in this.
Our impact on the world and its systems is greatly influenced by where we get our energy. To combat climate change, decarbonising is our greatest hope to rebalance the planet's resources and our ecological footprint.
Food production now takes up around half of Earth's biocapacity. Sustainability is influenced by how we address one of our most fundamental needs, food. Several factors influence the quality of our food: the region from which it originates, the method by which it is transported, and even the type of food itself. Reducing our meat intake will create the biggest difference.
Five areas of change are the focus of the #MoveTheDate campaign: the planet, cities, population, energy, and food.
Research conducted in 2019 by Global Footprint Network and Schneider Electric revealed that decarbonizing power and improving the energy efficiency of existing structures might help move Earth Overshoot Day back by 21 days. The date may be reserved by 10 days if food waste could be cut in half. Global CO2 emissions may be cut in half, saving 93 days in total. The date may also be pushed back 17 days if people stopped eating meat.
The speed of regression has recently been slowed down by some of the actions already being taken globally. According to the organisation, Earth Overshoot Day has moved up the calendar by less than one day a year on average over the past five years as opposed to about three days annually before that.
If we can push the Overshoot Day back by 5 days per year, then by 2054 we will be living within the boundaries of the planet again.
