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 2022, humanity has been using natural capital 71% faster than Earth can renew it, which they describe as meaning humanity's ecological footprint corresponds to 1.71 planet Earths.
Global Footprint Network publishes every year results for all nations captured in UN statistics. The algorithms of ecological footprint accounts have been used in combination with the emergy methodology (S. Zhao, Z. Li and W. Li 2005), and a sustainability index has been derived from the latter.
Impact may be measured using ecological footprint analysis in units of global hectares (gha). Ecological footprint per capita is a measure of the quantity of Earth's biologically productive surface that is needed to regenerate the resources consumed per capita. Impact is modeled as the product of three terms, giving gha as a result.
Global Footprint Network, a partner organization of New Economics Foundation, launches a campaign every year for EOD to raise awareness of Earth's limited resources. Global Footprint Network measures humanity's demand for and supply of natural resources and ecological services.
Global heating, although it is catastrophic, is merely one aspect of a profound polycrisis that includes environmental degradation, rising economic inequality, and biodiversity loss. Climate change is a glaring symptom of a deeper systemic issue: ecological overshoot, where human consumption outpaces the Earth's ability to regenerate.
Global biocapacity' is a term sometimes used to describe the total capacity of an ecosystem to support various continuous activity and changes. When the ecological footprint of a population exceeds the biocapacity of the environment it lives in, this is called an 'biocapacity deficit'.
The global hectare (gha) is a measurement unit for the ecological footprint of people or activities and the biocapacity of the Earth or its regions. One global hectare is the world's annual amount of biological production for human use and human waste assimilation, per hectare of biologically productive land and fisheries.
