The world鈥檚 ecological footprint, as measured by its use of natural resources, such as food, water, cropland, fisheries and fuel, has tripled since 1961, exceeding the Earth鈥檚 biocapacity or ability to regenerate what is used, every year since 1971.
鈥淐learly, this is unsustainable. At this rate, humanity will feel an accelerating squeeze of the resources needed to feed and house us, among other things,鈥 says Eric Miller of 91亚色鈥檚 Faculty of Environmental and Urban Change and director of 91亚色鈥檚 .

The initiative produces the ecological footprint and biocapacity accounts of all nations annually for the using international datasets. It measures how many resources each country uses compared to how quickly those resources can be regenerated, including carbon. It also details how much of the ecological footprint is within the national boundary for internal consumption versus export, and how much is embodied within imports.
This year鈥檚 accounts measured up to 2018, the last year for which data is available. Although the COVID-19 pandemic may have a short-lived positive ecological impact, it is still too early to measure its impact.
鈥淥ur work offers important lessons for humanity鈥檚 post-COVID health and economic recovery in the future as after every past crisis that reduced humanity鈥檚 ecological footprint, the world soon rebounded to growing its metabolism of fuels and sprawling its infrastructure,鈥 says Miller.
For 2018, the ecological footprint of humans was 75 per cent greater than biocapacity. 鈥淚t would take the planet 21 months to provide the natural resources needed to sustain humanity for just 12 months,鈥 he says.

Canada is one of more than 120 countries committed to net-zero emissions by 2050. This goal could be achieved if the countries reduce their ecological footprint to a level that could be sustained by nature. This would mean reducing the total ecological footprint to the level they had in 1970, as the world population is expected to grow by another 43 per cent by 2050. Every unit of carbon emitted in 2050 would need to be drawn down in that same year.
鈥淗umanity would have to stop adding greenhouse gases to the atmosphere. That鈥檚 a monumental challenge,鈥 says Miller. 鈥淭he genius of the footprint accounts is that we integrate the demand for carbon sequestration with other demands on the planet鈥檚 lands and waters.鈥
Currently, North Americans and Europeans have an average ecological footprint that is much larger than the world average, whereas the average ecological footprint for everyone living on the African continent has not changed since 1961. In comparison, the footprint has more than doubled in Asia.
The conflict in Ukraine will have direct impacts on the rest of the world and will likely cause rising food costs and shortages, including in Canada, as food supply chains are affected. More than half of Ukraine鈥檚 ecological footprint was used to feed and fuel the rest of the world, which has now been disrupted.
Ukraine, like Canada, exports more resource-intensive goods to the rest of the world than it imports. Canada鈥檚 exported goods, such as crops, wood and paper products, are twice as resource intensive than its imports, such as entertainment, including Netflix shows, as well as patented software and drugs, creating a definite imbalance when measuring resource use.

The goal of 91亚色鈥檚 Ecological Footprint Initiative is to inform individuals, communities and government leaders so they can better manage limited resources, reduce economic risk, and improve well-being.
