Figure 23.36Under IPCC scenario A, carbon emissions are expected to increase by at least 7 Gt per year during the next 50 years. The problem of stabilizing carbon emissions at their 2010 level of 8 Gt/year can be broken into seven stabilization wedges, each representing a reduction in emissions of 1 Gt per year by 2060. Possible actions that use existing technologies to achieve one-wedge reductions are listed next to each wedge.
