Humanity has burned through Earth’s annual budget for resources in under eight months.Known as Earth Overshoot Day, 2 August marks the date on which we’ve used up all the resources that the planet can regenerate in one year.“Persistent overshoot leads to ever more prominent symptoms including unusual heatwaves, forest fires, droughts, and floods with the risk of compromising food production,” says Steven Tebbe, CEO of the Global Footprint Network - the organisation which produces the estimate.This year’s date is months earlier than the first Overshoot Day on 25 December 1971.But there is good news as we’ve used our annual budget roughly five days later than in 2022 - and the pace at which it is moving forward is slowing down.There’s still a lot that needs to change, however, to stop humanity from burning through nearly two planets worth of resources every 12 months.Overshoot Day is calculated using UN data to work out each country’s ecological footprint and the ‘biocapacity’ of the planet.
Biocapacity is Earth’s ability to produce renewable resources and absorb waste, while the ecological footprint measures demand on nature including consumption of resources and emissions.
Global warming caused by vast amounts of CO2 from the burning of fossil fuels is driving the deficit, according to the Global Footprint Network.
The organisation says that achieving a 43 per cent cut in global emissions by the end of the decade would require Overshoot Day to be pushed back by 19 days every year between now and 2030.
