Ecological Footprint

Ecological Footprint Difference Between Wants & Needs Your Impact Reducing Our Footprint

YOUR Ecological Footprint Ecological Footprints are a measure of human impact on the Earth. The footprint equals the Earth’s cost to sustain one person. It’s measured in hectares (or global hectares “gha”) and represents the land area needed to provide resources and absorb waste and greenhouse gases produced by an individual.

Ecological Footprint & Bio-capacity Bio-capacity = The Earth’s ability to meet human demands.

Ecological Footprint & Bio-capacity by Region Country/Region Total Ecological Footprint (gha per person) Total Bio-capacity (gha per person) World 2.69 2.06 Africa 1.37 1.80 Middle East & Central Asia 2.32 1.28 Asia - Pacific 1.62 0.82 Latin America & Caribbean 2.44 4.80 North America 9.19 6.49 Europe (EU) 4.69 Europe (Non-EU) 3.52 5.81 Canada 7.07 20.05

Canada’s Current Footprint http://www.nationmaster.com/graph/env_eco_foo-environment-ecological-footprint

Ecological Footprint of Nations The map on the following slide shows various countries and regions of the world proportionate to their production and consumption of commercially traded fuels. All figures are in million metric tons of oil equivalent.

Ecological “Fuel” Footprint of Nations

Ecological Footprint of Nations World Average – 2.2 hectares Biggest Footprint – United States – 9.6 hectares Smallest Footprint – Bangladesh – 0.5 hectares Average Canadian Footprint – 8.6 hectares Canada has the 3rd highest footprint in the world! Why is Canada’s average footprint so big? What can we do to reduce our footprint?
