2. Ecological footprint - Wikipedia

   en.wikipedia.org/wiki/Ecological_footprint

   A modified ecological footprint that takes biodiversity into account has been created for use in Australia. [98] Ecological footprint for many years has been used by environmentalists as a way to quantify ecological degradation as it relates to an individual. Recently, there has been debate about the reliability of this method. [99]

3. Carbon footprint - Wikipedia

   en.wikipedia.org/wiki/Carbon_footprint

   The carbon footprint explained Comparison of the carbon footprint of protein-rich foods [1]. A formal definition of carbon footprint is as follows: "A measure of the total amount of carbon dioxide (CO 2) and methane (CH 4) emissions of a defined population, system or activity, considering all relevant sources, sinks and storage within the spatial and temporal boundary of the population, system ...

4. Sustainability metrics and indices - Wikipedia

   en.wikipedia.org/wiki/Sustainability_metrics_and...

   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. They have also been combined with a measure of quality of life , for instance through the " Happy Planet Index " (HPI) calculated for 178 nations ...

5. Sustainability measurement - Wikipedia

   en.wikipedia.org/wiki/Sustainability_measurement

   Two related concepts for sustainability measurement are planetary boundaries [7] and ecological footprint. [8] If the boundaries are not crossed and the ecological footprint does not exceed the carrying capacity of the biosphere, the mode of life can be regarded as sustainable.

6. I = PAT - Wikipedia

   en.wikipedia.org/wiki/I_=_PAT

   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.

7. Global hectare - Wikipedia

   en.wikipedia.org/wiki/Global_hectare

   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.

8. List of countries by ecological footprint - Wikipedia

   en.wikipedia.org/wiki/List_of_countries_by...

   This is a list of countries by ecological footprint. The table is based on data spanning from 1961 to 2013 from the Global Footprint Network's National Footprint Accounts published in 2016. Numbers are given in global hectares per capita. The world-average ecological footprint in 2016 was 2.75 global hectares per person

9. Ecological yield - Wikipedia

   en.wikipedia.org/wiki/Ecological_yield

   Ecological yield is a theoretical construct which aggregates information from several physically measurable quantities. It can be used to reason about other ecological indicators such as the footprint. It can also be used as a decision-making tool for governments and corporations.
