In its Fourth Assessment Report, the Intergovernmental Panel on Climate Change has confirmed that climate change is real, has quantified its magnitude and future evolution, and has assessed its impact. The 2006 Stern report concluded that the economic costs of climate change are significant. There are many ways to mitigate climate change, and results of action undertaken through the Kyoto Protocol are now visible. This paper examines alternative policies for mitigating and adapting to climate change, beyond the year 2012 horizon of Kyoto, and how India can play an important role in this effort.
