The only metric that tracks how much nature we have — and how much nature we use

Our economy is running a Bernie Madoff-style Ponzi scheme with the planet. We use future resources to run the present, using more than Earth can replenish. Like any such scheme, this works for a limited time, followed by a crash.

Avoiding ecological bankruptcy requires rigorous resource accounting — a challenging task, but doable with the right tools.

Ecological Footprint accounting, first introduced in the 1990s and continuously developed, continues to be the only metric that compares overall human demand on nature with what our planet can renew — its biocapacity — and distils this into one number: how many Earths we use.

Ecological Footprint provides a complete introduction, covering:

Footprint and biocapacity accounting Data and key findings for nations Worldwide examples including businesses, cities, and countries Strategies for creating regenerative economies

Whether you’re a student, business leader, future-oriented city planner, economist, or have an abiding interest in humanity’s future, Footprint and biocapacity are key parameters to be reckoned with and Ecological Footprint is your essential guide.
