A carbon footprint is a representation of the effect
an individual or an organization has on the climate in terms of the
total amount of greenhouse gases produced (measured in units of carbon
dioxide).
Footprinting is now widely used around the globe as
an indicator of environmental sustainability. It can be used to measure
and manage the use of resources throughout the economy. It is also
commonly used to explore the sustainability of individual lifestyles,
goods and services, organizations, industry sectors, neighborhoods,
cities, regions and nations.
