The Ecological Footprint Calculator measures resource consumption and converts this to the amount of land needed to supply the resources and assimilate the waste generated. It may help you identify the environmental impacts of everyday activities and encourage progress towards more sustainable practices.The questions require information about the types and amounts of products and resources used in your office, enabling you to estimate how many global hectares are required to support the activities of your work place – in other words, what sort of footprint are you leaving on the planet Earth.
