What is Earth Overshoot Day?
Why Earth Overshoot Day matters, how it’s calculated and what you can do to help #MoveTheDate
From the food we eat to the materials we build with, living in balance with the planet means not taking more than it can replenish. And when it comes maintaining a safe climate, it means not emitting more carbon dioxide than our natural world can reabsorb.
There is a limit to how much the planet can regenerate what we take from it. The day when we as humanity have officially used up our yearly ecological budget is called Earth Overshoot Day. This year, it falls on Thursday 30 July.
This means that for the rest of 2026, we’re effectively in debt to our planet – borrowing resources from future years instead of living within our means.
How is Earth Overshoot Day measured?
Earth Overshoot Day is an awareness-raising campaign set up by the Global Footprint Network, an international research organisation dedicated to providing tools to help cities and countries live within their ecological limits.
The Global Footprint Network measures the demand different countries put on their available natural resources, tracking areas such as population, food demand, material demand and energy use.
The diagram above shows that we’ve been using more than what the earth can replenish each year for over half a century.
Is Earth Overshoot Day the same for each country?
As well as the average date when humanity has used up the planet’s ecological budget, Global Footprint Network also provides a date per country. This is because countries use resources at different rates.
The diagram to the right shows that:
- If everyone had the lifestyle of an average person in Qatar, Earth Overshoot Day would fall on 4th February.
- If everyone in the world used resources at the rate we do in the UK, Earth Overshoot Day would have fallen on 12th May.
- If everyone had the lifestyle of an average person in Ecuador, Earth Overshoot Day would fall on 12th November.
We all have work to do to live sustainably and protect the planet. But some countries have more work to do than others.
Does earth overshoot day move?
Earth overshoot date fluctuates slightly every year. In 2026, it falls six days later than it did in 2025. However, this doesn’t mean humanity is suddenly living more sustainably.
According to Global Footprint Network, this year’s later date is largely the result of updated scientific data and improvements to the way Earth’s biocapacity is calculated. On a consistent dataset, 2026 actually represents the highest level of ecological overshoot ever recorded, with humanity continuing to consume natural resources faster than the planet can regenerate them.
At the current rate of consumption, humanity is using nature around 73% faster than Earth’s ecosystems can regenerate, meaning we would need the equivalent of 1.73 Earths to sustainably provide all the resources we use today.
What we do know is that progress is still far too slow. Global Footprint Network estimates that halving carbon dioxide emissions from fossil fuels would move Earth Overshoot Day back by almost three months, showing just how significant the impact of reducing fossil fuel use could be.
What can we do to #MoveTheDate?
Thankfully, there are a lot of actions we can all take to tread more lightly on our planet. Governments and corporations must address the huge impact of using fossil fuels for energy and transport, but collectively individuals can make meaningful changes too.
Here are some of the ways in which you can decrease your own environmental footprint:
1. Eat a planet friendly diet
When it comes to the food we eat, there’s one rule that’s as good for our health as it is for the planet: everything in moderation. Buy from local, sustainable producers, think about reducing the amount of meat and dairy you eat, and look into greener farms that are kinder to the environment.
2. Use your voice to demand change
With the vast majority of the world’s population expected to live in cities and urban areas by 2050, get involved in making the place you live more sustainable. From supporting campaigns for electric public transport and better cycling and walking routes, to writing to your MP about tackling air pollution.
3. Use energy sustainably
Finally, try to reduce the amount of energy that gets wasted by making your home more efficient, by using efficient appliances, installing insulation and remembering to turn things off when they aren’t in use. And, when you do use energy, make sure it’s genuinely renewable.
Earth Overshoot Day is a reminder that the small choices we make every day add up. Whether it’s wasting less energy, eating more sustainably or choosing genuinely renewable electricity, we all have a role to play in helping #MoveTheDate.
