3. 6 Basic assumptions of the calculation
Majority of the resources which are consumed can be quantified
The most of these resource and waste flows can be measured in terms of the biologically productive areas.
Areas which are differently biologically productive can be converted in Global Hectare
Global hectares can be added
Human demand of resources and the nature’s supply in Global Hectares can be compared directly.
Calculated demanded area can exceed the available supplied area
6 Basic assumptions of the calculation

4. Each global hectare has the same amount of bioproductivity.

5. Total Ecological Footprint & Total Biological Footprint
Consumption = Production + Imports – Exports
Land use types
Carbon Footprint

10. Trends of footprint calculation I
Suggestions to improve data base
Improvement of better transparancy and comprehensibility
Use of sensitive analyses and paste results
Adaption of the footprint data with national statistics
Comparison of alternative data and correction of valuation
Replacement of inexact data and hypotheses on national plain
The same data base for indicators for resource use
Trends of footprint calculation I
