Published to coincide with the Rio+20 Conference on Sustainable Development, UNEP's 2012 Global Environmental Outlook (GEO-5) calls on world leaders to take immediate action to address international environmental degradation and turn world-wide discussion of sustainable development into practice. GEO-5 builds on the findings of previous GEO reports, outlines the current state of the environment, projects future environmental trends and focuses on the smart policies that could put the world on the path to a sustainable future.
