	July 24th marks Earth Overshoot Day 2025, the date when humanity’s demand for natural resources exceeds what Earth can regenerate in a year. Calculated by the Global Footprint Network using data from York University, this year’s date is the earliest ever recorded. It reflects the reality that we are currently using nature 1.8 times faster than ecosystems can replenish. This overshoot stems from excessive carbon emissions, overconsumption of freshwater, deforestation, overfishing, and other unsustainable practices that erode the planet’s natural capital and threaten long-term resource security, particularly for already vulnerable populations.

−	The consequences of ecological overshoot are widespread and intensifying. It drives biodiversity loss, resource depletion, and the accumulation of greenhouse gases, which in turn fuel extreme weather, food and energy insecurity, health crises, economic stagnation, and geopolitical conflict. Despite its early timing, Earth Overshoot Day has remained within a narrow calendar window for over 15 years, indicating a persistent overuse of natural resources. The cumulative impact of this annual overspending deepens our ecological debt, making each subsequent year more precarious.	+	The consequences of ecological overshoot are widespread and intensifying.

	From an economic standpoint, overshoot represents a market failure, where the true cost of nature’s services is not reflected in market prices. This failure leads to underpriced resource inputs, encouraging overuse and increasing the likelihood of future disruptions and economic shocks. It also deprives biocapacity providers—those who manage and protect natural resources—of fair compensation. To prevent ecological and economic collapse, this market failure must be corrected through deliberate policy and systemic change, ending overshoot by design rather than by disaster.

Another way to look at the data is to look at what has been coined [https://overshoot.footprintnetwork.org/country-deficit-days/ Country Deficit Days] which given global overshoot, might be more relevant.

	The day is calculated by estimating the capacity of global ecosystems to produce the biological materials required by humans and its ability to absorb the waste material generated by humans over a year, referred to as biocapacity. This figure is then divided by the ecological footprint of humans in terms of material use, waste, emissions and so on. The result is then multiplied over the 365 days of the year to give an indicative day when effectively global resource would run out if used sustainably. After that day until the end of the year, demands are effectively being met through the depletion of natural resources and the accumulation of waste, such as carbon dioxide in the atmosphere and oceans, pushing essential global ecosystems closer to the point of collapse.

This marks the tenth consecutive annual reduction (excluding the pandemic years), driven mainly by cuts in the electricity supply and industry sectors, including the closure of the last coal-fired power station. However, rising emissions from aviation, which now exceed those from electricity, pose a growing challenge and risk to future targets.

		+	Over 80% of emissions cuts needed by 2030 must come from sectors beyond energy supply, especially through electrifying surface transport, buildings, and industry. Continued decarbonisation of the electricity system is essential to support this transition, with further reductions beyond 2030 also relying on progress in aviation, agriculture, land use, and engineered carbon removals. The graph below from the report shows that by 2030 3.4% of total reductions needs to come from buildings, with this increasing to 4.9% in the following period.

−	The day is calculated by estimating the capacity of global ecosystems to produce the biological materials required by humans and its ability to absorb the waste material generated by humans over ~~one~~ year, referred to as biocapacity. This figure is then divided by the ecological footprint of humans in terms of material use, waste, emissions and so on. The result is then multiplied over the 365 days of the year to give an indicative day when effectively global resource would run out if used sustainably. After that day until the end of the year, demands are effectively being met through the depletion of natural resources and the accumulation of waste, such as carbon dioxide in the atmosphere and oceans, pushing essential global ecosystems closer to the point of collapse.	+	The day is calculated by estimating the capacity of global ecosystems to produce the biological materials required by humans and its ability to absorb the waste material generated by humans over a year, referred to as biocapacity.

	Whilst formally the current period, since the last Ice age (Pleistocene) is known as the Holocene epoch, the Anthropocene is often used to describe a new geological epoch resulting from "[https://www.ipcc.ch/report/sixth-assessment-report-working-group-i/ significant human-driven changes to the structure and functioning of the Earth System, including the climate system].’ There are many and very varied estimates of when the Anthropocene is considered to have started, ranging from the early agricultural revolution or the industrial revolution to the the 1950's but all mark points significant increases in global emissions, natural resource use or waste production.
