land footprint
Land footprint is the real amount of land, wherever it is in the world, that is needed to produce a product, or used by an organisation or by a nation.〔(Giljum, S., Lutter, S., Bruckner, M., Aparcana, S., Heinke, J., Gerten, D. et al. (2013, May 3). State-of-Play of National Consumption-Based Indicators: A review and evaluation of available methods and data to calculate footprint-type (consumption-based) indicators for materials, water, land and carbon. ) Vienna: Sustainable Europe Research Institute.〕
== Origins ==
Land footprint is a consumption-based indicator, i.e. it looks at the resources needed to create a final product, or by an organisation or country, wherever they are in the world. This is in contrast to production-based indicators, which just look at resource use within a country. For example, cows will require land to graze on within a country, but may also be fed by feed grown on land in another country. This production vs consumption approach is extensively discussed in greenhouse gas emissions accounting, where carbon footprint is the consumption-based indicator.
