Q: Ecological Footprint accounting measures the demand on and supply of nature.

On the demand side, the [...] adds up all the productive areas for which a population, a person or a product competes. It measures the ecological assets that a given population or product requires to produce the natural [...] it consumes (including plant-based food and fiber products, livestock and fish products, timber and other forest products, space for urban infrastructure) and to absorb its [...], especially carbon [...].

The Ecological Footprint tracks the use of productive surface areas. Typically these areas are: [...], grazing land, fishing grounds, built-up land, forest area, and carbon demand on land.

On the supply side, a city, state or nation’s [...] represents the productivity of its ecological assets (including cropland, grazing land, forest land, fishing grounds, and built-up land). These areas, especially if left unharvested, can also serve to absorb the waste we generate, especially our carbon emissions from burning fossil fuel.
