Total Ecological Footprint vs Annual CO2 Emissions
Fórmula
## 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
Ejemplo Resuelto
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
Preguntas Frecuentes
What is a global hectare?
A global hectare (gha) is a unit representing the average biological productivity of all productive hectares on Earth. It allows comparison across different land types and countries.
How many Earths does humanity currently use?
Humanity currently uses about 1.75 Earths worth of resources, meaning we consume resources faster than they regenerate. Earth Overshoot Day falls in late July.
What has the biggest impact on ecological footprint?
Carbon emissions (energy and transport) account for about 60% of the global ecological footprint. Food production is second at about 25%. Reducing these two areas has the greatest effect.
