Enter details about your diet, travel habits, home energy use, and shopping patterns to find out your Ecological Footprint. The calculator estimates how many global hectares of land your lifestyle requires and how many Earths would be needed if everyone lived the same way.

An ecological footprint measures the amount of biologically productive land and water area required to sustain a person's lifestyle and absorb their waste. It is expressed in global hectares (gha). Comparing your footprint to Earth's available biocapacity shows whether humanity is living within the planet's means.
As of recent estimates, humanity collectively uses the equivalent of about 1.7 Earths per year — meaning we consume natural resources 70% faster than the planet can regenerate them. This overshoot is driven largely by carbon emissions, deforestation, and unsustainable food systems.
A global hectare is a standardized unit representing one hectare of biologically productive land or water with average world productivity. It allows different types of land use — cropland, forests, fisheries, grazing land — to be compared on a common scale.
For most people in high-income countries, diet (especially meat consumption), air travel, and home energy use are the three largest contributors to their ecological footprint. Switching to a plant-based diet and reducing flying can each cut your footprint by 20–40%.
Earth Overshoot Day marks the date in the year when humanity has used all the biological resources that Earth can regenerate in that entire year. The remaining months are run on ecological deficit. This calculator estimates your personal overshoot day based on your lifestyle.
This calculator uses consumption-based footprint methodology, applying category multipliers for food, housing, transport, and goods to country-level baseline data. The result is an approximation — detailed footprint studies use household spending surveys — but it provides a realistic relative comparison.
Earth's total biocapacity divided by the global population works out to roughly 1.6 global hectares per person. To live within the planet's limits, each person's footprint should ideally stay below that level. Most residents of high-income countries have footprints of 4–9 gha.
The highest-impact actions are: eating less (or no) meat and dairy, eliminating or reducing air travel, switching to renewable home energy, choosing an electric or no car, and buying fewer new goods. Systemic changes like switching energy providers or advocating for policy change can multiply your personal impact.
