IPCC: GHG emissions accelerating despite mitigation efforts; major institutional and technological change required to keep the heat down

Green Car Congress

Decomposition of the decadal change in total global CO 2 emissions from fossil fuel combustion by four driving factors; population, income (GDP) per capita, energy intensity of GDP and carbon intensity of energy. The global economic crisis 2007/2008 only temporarily reduced emissions. WG III Summary for Policymakers. Click to enlarge.
