English: Shows in graphic form the projected increase in
carbon dioxide (CO
2) emissions from
fossil fuels in five of the
emissions scenarios used by the
Intergovernmental Panel on Climate Change (IPCC), compared to the
International Energy Agency's (IEA's) actual observational CO
2 emissions data from
fossil fuel consumption.
The graph shows five of the illustrative "marker" scenarios from the IPCC's Special Report on Emissions Scenarios (SRES). The SRES report contains a total of 40 greenhouse gas emissions scenarios. Between the years 2000-2009, growth in CO2 emissions from fossil fuel burning was, on average, 3% per year, which exceeds the growth estimated by 35 of the 40 SRES scenarios (34 if the trend is computed with end points instead of a linear fit) (Le Quéré et al., 2010).
