Total Ecological Footprint vs Food Footprint
Formula
## 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.
Exemplo Resolvido
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
Perguntas Frequentes
What is a global hectare?
A global hectare (gha) is a productivity-weighted hectare used to measure ecological footprints. It accounts for different land productivities worldwide.
How many Earths are we currently using?
Humanity currently uses about 1.75 Earths worth of resources annually, meaning we consume more than the planet can regenerate in a year.
What has the biggest impact on my footprint?
For most people, transportation (especially flying) and food (especially meat) are the largest components. Housing energy and consumer goods follow.
