The Ecological Footprint is a measure of humanity's demands on nature.

Essentially, an ecological footprint measures the area of productive ecosystem required to support a given level of production or consumption. Calculating an ecological footprint involves expressing all material and energy inputs to a product or service system in terms of the productive ecosystem required to produce them, as well as the area of forest necessary to sequester the associated greenhouse gas emissions. This measure allows us to understand and wisely manage our finite global ecology. It is increasingly used by individuals, firms, communities and governments to inform sustainable development considerations. At Global Ecologic, we have a strong history in food system ecological footprinting for environmental supply chain management.
