As human populations and consumption increase, we place greater demands
on ecosystems that are essential for the survival of not only humanity but
wildlife species as well.


The threats facing the rich array of plant and animal life on the planet seem greater than at any time in modern history. Problems such as climate change, water shortages, overharvesting and habitat disruption—symptoms of human pressure on the planet’s finite resources—are driving down wildlife populations worldwide.

In 2002, under the auspices of the Convention on Biological Diversity (CBD) the leaders of the world’s governments committed to significantly halting the rate of biodiversity loss by 2010. They adopted a suite of indicators, brought together as the Biodiversity Indicators Partnership (BIP), to provide information on biodiversity trends and assess progress toward their target. Global Footprint Network is a BIP Key Indicator Partner, and the Ecological Footprint has been officially adopted by the CBD to be included among its biodiversity indicators.

What can the Footprint tell us about biodiversity?

While not a direct measure of species populations, the Ecological Footprint provides an indicator of the pressure on ecosystems and biodiversity by measuring the competing level of ecological demand that humans place upon the biosphere.

Global Ecological Footprint data show that humanity is using resources and producing CO2 emissions at a rate 60 percent greater than what nature can regenerate and reabsorb. This gap, known as ecological overshoot, results in the depletion of the natural capital that all species (including our own) depend on for their livelihood. It also results in the accumulation of carbon dioxide that leads to climate change, with profound implications for ecosystems and the species they support as well as for our societies well being and economic stability.

Humanity’s Ecological Footprint has grown 80 percent over the last four decades. The greater the gap between human demand and nature’s regenerative capacity, the more pressure there will be on the resources other species need to survive, and the more perilously biodiversity will be under threat.

Looking at the various consumption sectors that go into the Ecological Footprint can provide us with a glimpse of the human activities that are drivers of biodiversity loss.

Meeting the Biodiversity Challenge

A 2010 report in the journal Science to which Global Footprint Network was a contributor provided a stark assessment that the world’s governments had not met the target set by the Convention on Biological Diversity, and had instead presided over enormous declines.

In October 2010, the parties to the CBD met in Nagoya, Japan to decide whether to adopt a new biodiversity target and new indicators for the post-2010 era. At the conference, the BIP presented a list of strategic goals, including means, milestones and indicators, for achieving the goals set forth in the CBD.

Ultimately halting species loss and enabling biodiversity to thrive will require bringing human demand for ecological services into balance with what nature can renewably supply.

By advancing decision-making that takes resource limits into account, Global Footprint Network is working to promote a world where the reality of resource constraints is central to the national and international policy debate, and where decision-makers understand the risks that resource limitation and declining biodiversity pose to our societies’ well-being and economic stability.

IPBES adopts Ecological Footprint as a Core Indicator

The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), an independent intergovernmental body established in 2012, has added Ecological Footprint and biocapacity metrics to its list of Core Indicators. Using Footprint data, IPBES recognizes as a scientifically “well established” trend that countries with an ecological deficit put tremendous pressure on resource security and biodiversity outside of their borders.

Living Planet Report

Every two years, Global Footprint Network, WWF, and the Zoological Society of London publish the Living Planet Report, the world’s leading science-based analysis on the health of our planet and wildlife populations and the impact of human activity. Global Footprint Network has collaborated with WWF on the biennial Living Planet Report since 2000.
