Total Ecological Footprint vs Food Footprint
Ecological Footprint
Your ecological footprint is the total area of productive land and water needed to produce what you consume and absorb your waste, measured in global hectares (gha).
Formula
Total Footprint = Food + Housing + Transport + Goods (all in gha)
Earths Needed = Total Footprint / Biocapacity per person
The world has about 1.6 gha of biocapacity per person. The average American uses about 8 gha, meaning if everyone lived like an American, we would need 5 Earths.
Example Calculation
A person with moderate consumption across four categories.
- 01Total = 1.2 + 0.8 + 1.5 + 1.0 = 4.5 gha
- 02Earths needed = 4.5 / 1.6 = 2.8 Earths
