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

Benchmarks

  • World average: 2.7 gha
  • US average: 8.1 gha
  • Earth's biocapacity: ~1.6 gha per person
  • If everyone lived like Americans, we would need 5 Earths
  • Example Calculation

    An American with 12 tons CO2, moderate food, 2,000 sq ft home, $1,000/month spending.

    1. 01Carbon: 12 * 0.34 = 4.08 gha
    2. 02Food: 1.2 * 0.9 = 1.08 gha
    3. 03Housing: 2,000 * 0.0003 = 0.60 gha
    4. 04Goods: 1,000 * 12 * 0.00005 = 0.60 gha
    5. 05Total: 4.08 + 1.08 + 0.60 + 0.60 = 6.36 gha
    6. 06Earths needed: 6.36 / 1.6 = 4.0 planets
