The Special Report has been planned by IPCC with the following aims: first, to promote understanding of the vulnerability to and impacts of climate change, current and future climate variability and extreme events, and the implications for sustainable development; to review the wide range of efforts undertaken by Governments and communities to promote and implement disaster risk reduction, sustainable development, and environmental risk management, thus reducing the extent to which extreme events result in disasters; Third, to assist the IPCC in its decision-making by assessing the humanitarian consequences of climate change.
