The ecological footprint is a statistical tool designed to assess the impact of consumption on the ability to renew resources.
The basic concept is that every human activity involves consumption of natural resources quantifiable in terms of area (ha ha), depending on the type of consumption will be referred to a type of surface rather than another. Comparing
the ecological footprint of an individual (or a region, or state) with the area available per capita (ie the ratio between total area and population) can you tell if the level of consumption is sustainable or not. To calculate this divide the resource consumption (in kilograms, kg) and capacity (Kg / Ha): the result is a surface.
can provide valuable insights in principle with comparative value, but its significance in absolute terms is quite unrealistic, as a management tool is limited and its value is overstated.
Among the most important limits:
- reduces all values \u200b\u200bto a surface measure
- roughly estimate the energy efficiency
- does not consider the consumption of nonrenewable resources
- does not take adequate account of the disposal of degradable waste little
- chemical pollution not be considered, with the exception of carbon dioxide emissions
