	How the Happy Planet Index is Calculated
		Ecological footprint accounting measures the extent to which the ecological demand of human economies stays within or exceeds the capacity of the biosphere to supply goods and services.
		The ecological footprint measures how much land area is required to sustain a given population at present levels of consumption, technological development and resource efficiency, and is expressed in global-average hectares (gha).
		The largest component elements of Footprint are the land used to grow food, trees and biofuels, areas of ocean used for fishing, and most importantly the land required to support the plant life needed to absorb and sequester CO2 emissions from fossil fuels.

	What is an Ecological Footprint?
		Based on this relationship between humanity and the biosphere, an ecological footprint is a measurement of the land area required to sustain a population of any size.
		Footprints can be measured at an individual level, or for cities, regions, countries, or the entire planet.
		Footprints indicate how much "nature" is available for a defined population to use, compared to how much it needs to maintain its current activities.

	The Ecological Footprint: A resource accounting framework for measuring human demand on the biosphere — EEA (Site not responding. Last check: 2007-10-16)
		The Footprint of a population is the total amount of biologically productive land and water area that the population requires to produce the resources it consumes and absorb the waste it generates, using current technology.
		Since people consume resources and ecological services from all over the world, their Footprint is the sum of these areas, regardless of where they are located on the planet.
		The Footprint is used by governments, businesses, and organisations to measure and manage sustainability efforts, from communication and planning to implementation and evaluation of results.

	Ecological Footprint
		Ecological Footprint analysis can be used as a tool to raise awareness about the demands we make on the environment to supply our consumption needs and habits, and reabsorb the wastes generated from our activities.
		Once our Ecological Footprint is calculated, we will have a benchmark to set our personal footprint reduction goals and to measure our progress when we recalculate it at a later date.
		Footprint analysts have estimated that our fair earth share of resources amounts to two hectares per person, or a footprint that is 75% smaller than the average Canadian Ecological Footprint.

	SSC: Projects
		The Ecological Footprint Project was a community-based public awareness and action program that used the Ecological Footprint, a key tool for measuring the impact of human activity on the natural environment.
		For example, biologist E.O. Wilson, called "one of the twentieth century's greatest thinkers," considers the Footprint to be one of the most significant recent ecological inventions because of its ability to communicate complex scientific information in relatively simple terms to explain the relationship between human consumption and the natural environment.
		In a similar vein, Dr.Mathis Wackernagel, co-creator of the Ecological Footprint considers Sustainable Sonoma County to be one of the most advanced groups in the nation for using the Ecological Footprint to create social change at the community level.

	Evaluating Ecological Footprints (Site not responding. Last check: 2007-10-16)
		The author will argue below that the fossil fuel (energy) footprint, which is an extremely important calculation, is a different kind of footprint and that to sum it with the food/wood products/degraded land footprint is misleading and compromises the power of Ecological Footprint Analysis.
		Ecological Footprint Analysis of these real demands can give us some measure of the degree to which Earth's surface can sustainably support humanity's patterns of consumption as population grows and standards of living in developing countries rise.
		Energy footprint analysis shows that the amount of new forest needed is unrealistically huge, and thus there seems to be no satisfactory mitigation available to limit the buildup of carbon dioxide in the atmosphere.
