UNEP Releases Fourth Global Environment Outlook Report

Oct 25: The United Nations Environment Programme (UNEP) says that major threats to the planet such as climate change, the rate of extinction of species, and the challenge of feeding a growing population are among the many that remain unresolved, and all of them put humanity at risk. The warning comes in UNEP’s Global Environment Outlook: Environment for Development (GEO-4) report published 20 years after the World Commission on Environment and Development (the Brundtland Commission) produced its seminal report, Our Common Future.

GEO-4, the latest in UNEP’s series of flagship reports, assesses the current state of the global atmosphere, land, water and biodiversity, describes the changes since 1987, and identifies priorities for action. GEO-4 is the most comprehensive UN report on the environment, prepared by about 390 experts and reviewed by more than 1 000 others across the world. It salutes the world’s progress in tackling some relatively straightforward problems, with the environment now much closer to mainstream politics everywhere. But despite these advances, there remain the harder-to-manage issues, the “persistent” problems. Here, GEO-4 says, “There are no major issues raised in Our Common Future for which the foreseeable trends are favorable.”

Failure to address these persistent problems, UNEP says, may undo all the achievements so far on the simpler issues, and may threaten humanity’s survival. But it insists: “The objective is not to present a dark and gloomy scenario, but an urgent call for action.” Achim Steiner, UN Under-Secretary General and UNEP Executive Director said, “The international community’s response to the Brundtland Commission has in some cases been courageous and inspiring. But all too often it has been slow and at a pace and scale that fails to respond to or recognize the magnitude of the challenges facing the people and the environment of the planet”.

“Over the past 20 years, the international community has cut, by 95 per cent, the production of ozone-layer damaging chemicals; created a greenhouse gas emission reduction treaty along with innovative carbon trading and carbon offset markets; supported a rise in terrestrial protected areas to cover roughly 12 per cent of the Earth and devised numerous important instruments covering issues from biodiversity and desertification to the trade in hazardous wastes and living modified organisms.”

“But, as GEO-4 points out, there continue to be ‘persistent’ and intractable problems unresolved and unaddressed. Past issues remain and new ones are emerging -- from the rapid rise of oxygen ‘dead zones’ in the oceans to the resurgence of new and old diseases linked in part with environmental degradation. Meanwhile, institutions like UNEP, established to counter the root causes, remain under-resourced and weak.”

On climate change the report says the threat is now so urgent that large cuts in greenhouse gases by mid-century are needed. Negotiations are due to start in December on a treaty to replace the Kyoto Protocol, the international climate agreement which obligates countries to control anthropogenic greenhouse gas emissions. Although it exempts all developing countries from emission reduction commitments, there is growing pressure for some rapidly-industrializing countries, now substantial emitters themselves, to agree to emission reductions.

GEO-4 also warns that we are living far beyond our means. The human population is now so large that “the amount of resources needed to sustain it exceeds what is available... humanity’s footprint [its environmental demand] is 21.9 hectares per person while the Earth’s biological capacity is, on average, only 15.7 ha/person.“ And it says the well-being of billions of people in the developing world is at risk, because of a failure to remedy the relatively simple problems which have been successfully tackled elsewhere. GEO-4 recalls the Brundtland Commission’s statement that the world does not face separate crises - the “environmental crisis”, “development crisis”, and “energy crisis” are all one. This crisis includes not just climate change, extinction rates and hunger, but other problems driven by growing human numbers, the rising consumption of the rich and the desperation of the poor.

Regarding the future, GEO-4 acknowledges that technology can help to reduce people’s vulnerability to environmental stresses, but says there is sometimes a need “to correct the technology-centered development paradigm”. It explores how current trends may unfold by 2050 in four scenarios. The real future will be largely determined by the decisions individuals and society make now, GEO-4 says, “Our common future depends on our actions today, not tomorrow or some time in the future.”
