What is it?
An ecological footprint measures the impact of humans on Earth’s ecosystem. It is typically measured in area of wilderness, or amount of natural capital consumed each year. A common way of estimating footprint is by measuring the amount of wilderness (both land and sea) needed to supply resources for the human population. At a global scale, it is used to estimate how rapidly we are depleting natural capital.
How does it work?
The ecological footprint measures the supply of and demand on nature. On the supply side, biocapacity represents the planet’s biologically productive land areas including our forests, pastures, cropland and fisheries. These areas, especially if left unharvested, can also absorb much of the waste we generate, namely our carbon emissions.
The Global Footprint Network calculates the global ecological footprint from UN and other data. They estimate that as of 2007, our planet has been using natural capital 1.5 times as fast as nature can renew it.
Do you know your Land Footprint?
By measuring the footprint of a population—an individual, city, business, nation, or all of humanity—we can assess our pressure on the planet, which helps us manage our ecological assets more wisely and take personal and collective action in support of a world where humanity lives within the Earth’s bounds.
