Ecological Overshoot Day

Ecological Overshoot Day was
25 September 2009

As of 25 September we had used all the resources we should use for 2009 if we wanted to live sustainably.


Earth Overshoot Day comes on September 25 this year.

That means that, as of September , according to the calculations of the Global Footprint Network, humanity will have placed more demand on ecological services – from filtering CO2 to producing food, fiber and timber– than nature can provide in this year. From now until the end of the year, we will meet our demand for ecological services by depleting resource stocks and accumulating carbon dioxide in the atmosphere.
