How to Calculate Your Ecological Footprint
The ecological footprint measures how much biologically productive land and sea is needed to support your lifestyle.
Formula
Total gha = Carbon gha + Food gha + Housing gha + Goods gha
Earths Needed = Your Footprint / Earth's Biocapacity per Person

Example Calculation
An American with 12 tons CO2, moderate food, 2,000 sq ft home, $1,000/month spending.
- 01Carbon: 12 * 0.34 = 4.08 gha
- 02Food: 1.2 * 0.9 = 1.08 gha
- 03Housing: 2,000 * 0.0003 = 0.60 gha
- 04Goods: 1,000 * 12 * 0.00005 = 0.60 gha
- 05Total: 4.08 + 1.08 + 0.60 + 0.60 = 6.36 gha
- 06Earths needed: 6.36 / 1.6 = 4.0 planets
