This is a list of countries by ecological footprint. The table is based on data spanning from 1961 to 2013 from the Global Footprint Network 's National Footprint Accounts published in 2016. Numbers are given in global hectares per capita. The world-average ecological footprint in 2016 was 2.75 global hectares per person (22.6 billion in total).
The ecological footprint measures human demand on natural capital, i.e. the quantity of nature it takes to support people and their economies. [1][2][3] It tracks human demand on nature through an ecological accounting system. The accounts contrast the biologically productive area people use to satisfy their consumption to the biologically ...
The carrying capacity is defined as the environment 's maximal load, [clarification needed] which in population ecology corresponds to the population equilibrium, when the number of deaths in a population equals the number of births (as well as immigration and emigration). Carrying capacity of the environment implies that the resources ...
This ecological debt is often referred to as our global 'ecological overshoot'. The data from the Global Footprint Network has been used to create the graph below, it shows that since the 1970s the global population is increasingly compromising the Earth's ecosystem. The red section of the graph indicates that the global population have been ...
For people, "overshoot" is that portion of their demand or ecological footprint which must be eliminated to be sustainable, or the delta between a sustainable population and what we currently have. [1] [2] Excessive demand leading to overshoot is driven by both consumption and population. [3] Population decline due to overshoot is known as ...
I = (PAT) is the mathematical notation of a formula put forward to describe the impact of human activity on the environment. I = P × A × T. The expression equates human impact on the environment to a function of three factors: population (P), affluence (A) and technology (T). [1] It is similar in form to the Kaya identity, which applies ...
The Happy Planet Index (HPI) is an index of human well-being and environmental impact that was introduced by the New Economics Foundation in 2006. Each country's HPI value is a function of its average subjective life satisfaction, life expectancy at birth, and ecological footprint per capita. The exact function is a little more complex, but ...
Sustainability metrics and indices are measures of sustainability, using numbers to quantify environmental, social and economic aspects of the world. [1] There are multiple perspectives on how to measure sustainability as there is no universal standard. [2] Intead, different disciplines and international organizations have offered measures or ...
