Earth Overshoot Day 2017
lands on August 2.

By August 2, 2017, we will have used more from nature than our planet can renew in the whole year.

We use more ecological resources and services than nature can regenerate through overfishing, overharvesting forests, and emitting more carbon dioxide into the atmosphere than forests can sequester.

We say “stop!” Stop to Earth Overshoot Day creeping up the calendar year after year, as our global Ecological Footprint expands further beyond what the planet can renew.

Currently, carbon emissions make up 60% of humanity’s Ecological Footprint. Consider this: If we cut carbon emissions in half, the date of Earth Overshoot Day would be pushed back by 89 days, or about three months. This is possible, and would reduce humanity’s demand to the ecological resources of 1.2 planets instead of 1.7 as is the case now.

Over a year ago 190 countries committed to maintaining global warming below the 2 degree Celsius threshold. Imperfect as it may be, the Paris Climate Accord generated global goodwill and hope that humanity was ready at last to tackle its biggest challenge yet. On June 1st the Trump Administration reneged on America’s promise. We, in contrast are doubling up our commitment— together with many governments, businesses, NGOs, and individuals. Because it is necessary, possible and desirable to #movethedate.

Gaining 5 days every year is all it takes to bring humanity’s Ecological Footprint back to one planet before 2050. And solutions abound.

Explore Solutions

Thriving lives within the means of our planet are not out of reach. Plenty of solutions exist in four major areas for improving sustainability: food, cities, population, and energy to #movethedate.





How we meet one of our most basic needs–food–is a powerful way to influence sustainability. Sourcing food locally and avoiding highly processed foods can lower the Ecological Footprint. Learn More

Eighty percent of the world population is expected to live in cities by 2050. Consequently, city planning and urban development strategies are instrumental to balancing the supply of natural capital and population’s demand. Learn More

Being committed to everyone living secure lives in a world of finite resources requires addressing population growth. Empowering women is essential for global sustainability. Learn More

Decarbonizing the economy is our best possible chance to address climate change, and would improve the balance between our Ecological Footprint and the planet’s renewable natural resources. Learn More

Earth Overshoot Day is an initiative of Global Footprint Network, an international research organization that is changing the way the world measures and manages its natural resources. The date of Earth Overshoot Day is calculated with data from Global Footprint Network’s National Footprint Accounts, which are now available for free on our Ecological Footprint Explorer Open Data Platform at
