According to the World Wildlife Foundation, an ecological footprint is the impact of human activities measured in land and water used in the production of the goods needed to sustain a certain lifestyle. In sustainability terms, it is a comparison of what people consume compared to what they produce. Knowing an ecological footprint is important for understanding how one begins to live sustainably because it can give a maximum value for what that person is currently consuming. This maximum value is derived from multiple components of living a standard lifestyle.

At this time Australia had a ranking of 5.0, and currently it is ranked at 8.49. The current rating puts them at 7th in the world for largest footprint. The continent was analyzed for its land disturbance, energy usage in comparison to energy production, and import export comparisons. Australia is ranked top 15 for most of the major carbon footprint issues including CO2 emissions, emissions per capita, and waste generation. The
