The document summarizes key findings from the IPCC's Fifth Assessment Report regarding mitigation of climate change. It finds that: 1) Human influence on the climate system is clear and GHG emissions growth between 2000-2010 was larger than in previous decades. 2) Energy production, especially from fossil fuels, is the primary driver of GHG emissions. 3) Substantial and sustained reductions in GHG emissions are needed to limit global temperature increase to 2°C and avoid severe climate impacts. Measures exist to achieve the required emissions reductions through energy efficiency, low-carbon energy, carbon sinks, and lifestyle changes.
