Every two years, UN Habitat releases a report on human settlements. For 2011, the focus of the report was on cities and climate change. It highlights the role that cities play in contributing to climate change, the impacts of climate change on cities and on the potential for action in cities for mitigation and adaptation. It also identifies some innovative measures that have been implemented from around the world to address the issue.
