About this calculator
The Annual Ecological Footprint Calculator helps to calculate an individual's ecological footprint over a year. This includes the consumption of natural resources, such as water, food, fossil fuels and other products, as well as the generation of waste and greenhouse gas emissions.
The formula used is based on the Extended Footprint, a concept developed by the United Nations (UN) to measure the pressure that human activities have on the environment.
This tool is useful for individuals, families and companies that want to reduce their ecological footprint and live in a more sustainable way. It also helps to raise awareness about the environmental impacts of daily choices.
The average annual ecological footprint in Brazil is approximately 2.8 gha. This means that, on average, each Brazilian consumes natural resources as if they had a productive area of 2.8 hectares per year.
