Potential of Climate Change Mitigation - The IPCC Report

The 2007 IPCC report summarizes the potential for climate change mitigation sector-by-sector as follows:

Why climate change mitigation is necessary?

The projected climate changes in the twenty-first century are so large that, even at the low end of the range of possibilities, impacts will require costly adaptations, and in some cases our capacity to adapt will not be enough to avoid serious damage to individuals and society. It will therefore be necessary to reduce climate change by reducing net greenhouse gas emissions to the atmosphere. In the language used by the Intergovernmental Panel on Climate Change (IPCC) and the United Nations Framework Convention on Climate Change (UNFCCC), this is called ‘Mitigation’.
