The ecological footprint is a method promoted by the Global Footprint Network to measure human demand on natural capital, i.e. the quantity of nature it takes to support people or an economy. It tracks this demand through an ecological accounting system. The accounts contrast the biologically productive area people use for their consumption to the biologically productive area available within a region or the world (biocapacity, the productive area that can regenerate what people demand from nature). In short, it is a measure of human impact on the environment. Footprint and biocapacity can be compared at the individual, regional, national or global scale. Both footprint and biocapacity change every year with number of people, per person consumption, efficiency of production, and productivity of ecosystems. At a global scale, footprint assessments show how big humanity's demand is compared to what Earth can renew. Global Footprint Network estimates that, as of 2014, humanity has been using natural capital 1.7 times as fast as Earth can renew it, which they describe as meaning humanity's ecological footprint corresponds to 1.7 planet Earths.Lin, D; Hanscom, L; Murthy, A; Galli, A; Evans, M; Neill, E; Mancini, MS; Martindill, J; Medouar, F-Z; Huang, S; Wackernagel, M.

Overview The first academic publication about ecological footprints was by William Rees in 1992. The ecological footprint concept and calculation method was developed as the PhD dissertation of Mathis Wackernagel, under Rees' supervision at the University of British Columbia in Vancouver, Canada, from 1990–1994. Originally, Wackernagel and Rees called the concept "appropriated carrying capacity".Wackernagel, Mathis, 1991.

Report I & II to the UBC Task Force on Healthy and Sustainable Communities, Vancouver. To make the idea more accessible, Rees came up with the term "ecological footprint", inspired by a computer technician who praised his new computer's "small footprint on the desk".William Safire, On Language: Footprint, New York Times Magazine, February 17, 2008 In 1996, Wackernagel and Rees published the book Our Ecological Footprint: Reducing Human Impact on the Earth.Wackernagel, M. and W. Rees. 1996. Our Ecological Footprint: Reducing Human Impact on the Earth. Gabriola Island, BC: New Society Publishers. . Since 2003, Global Footprint Network has calculated the ecological footprint from UN data sources for the world as a whole and for over 200 nations (known as the National Footprint Accounts). The total footprint number of Earths needed to sustain the world's population at that level of consumption are also calculated. Every year the calculations are updated to the latest year with complete UN statistics. The time series are also recalculated with every update since UN statistics sometimes correct historical data sets. Results are available on an open data platform. Lin et al. (2018) finds that the trends for countries and the world have stayed consistent despite data updates.  Also, a recent study by the Swiss Ministry of Environment independently recalculated the Swiss trends and reproduced them within 1–4\% for the time period that they studied (1996–2015). Since 2006, a first set of ecological footprint standards exist that detail both communication and calculation procedures. The latest version are the updated standards from 2009.
