- the Ecological Footprint equation
- EFC = EFP + ( EFI - EFE )
- C : Consumption ( gha )
- P : Production ( gha )
- I : Imports ( gha )
- E : Exports ( gha )
- Ecological Footprint of Production
- EFP = Σ Ti * wAi * gAi
- EFP : Ecological Footprint of Production ( gha )
- i : Product i
- T : Tons( ton )
- wA : world-average Area per Ton ( wha / ton )
- gA : global Area per world-average Area ( gha / wha )
