Ecological Footprint Calculator
How many Earths does your lifestyle need? Estimate your ecological footprint in global hectares from diet, transport, housing, and consumption.
The ecological footprint measures the land and sea area needed to support your lifestyle, in global hectares. Earth’s biocapacity is about 1.6 global hectares per person; the global average footprint is about 2.7. Use the result as a planning estimate; individual circumstances vary.
Global average: ~2.7 gha/person.
Biocapacity: ~1.6 gha/person.
We currently use ~1.7 Earths.

What Is Ecological Footprint?
The ecological footprint converts everything you consume into the biologically productive area needed to provide it, measured in global hectares (gha).
Earth offers about 1.6 gha per person of biocapacity, but the global average footprint is ~2.7 gha, the definition of ecological overshoot.
How It Is Calculated
Footprint = base + diet + transport + housing + consumption (gha)
Earths needed = footprint ÷ 1.6 gha biocapacity
Example: Example: avg diet + car + medium home + moderate consumption → ≈ 3.1 gha (≈ 1.9 Earths)
Footprint benchmarks
| Country / lifestyle | gha per person |
|---|---|
| Biocapacity (fair share) | 1.6 |
| World average | 2.7 |
| U.S. average | ~8 |
| EU average | ~4.5 |
| India average | ~1.2 |
Limitations
- Questionnaire estimates are indicative, not precise accounting.
- Country-level components (shared infrastructure, public services) are simplified.
- Use for awareness and direction, not for policy.

Ecological Footprint FAQ
What is a global hectare?
A standardized hectare of world-average biological productivity, the unit that makes footprints comparable across countries.
How many Earths do we use?
About 1.7 Earths at current consumption, the origin of 'Earth Overshoot Day'.
What reduces an ecological footprint fastest?
Plant-forward diet, car-free mobility, smaller/insulated housing, and buying less, the same levers as the carbon footprint.
Is ecological footprint the same as carbon footprint?
Related but different: carbon counts greenhouse gases; ecological footprint counts land and sea area for all resources, including food and materials.
