Illustrations of how the matrix architecture can be used to look into the cost and benefits of climate policy (indicated by the different colours). Different categories of climate policy costs and residual impacts are expected to vary across the cells of the matrix. The empty cell (dashed lines) illustrate that not all combinations of forcing levels and SSPs may be consistent. Colours in the left hand matrix illustrate how achievement of lower forcing levels imposes a greater mitigation cost for any given SSP, but that this cost also depends on the SSP being followed. Colours in the right hand matrix suggest how the costs of avoiding a certain amount of impact (not specified here) through adaptation, combined with the impact costs that remain, are greater under some SSPs than others and under higher levels of forcing. The use of the framework to explore mitigation and adaptation policies is further elaborated in Kriegler et al. (Submitted for publication in this special issue). The 3.7 W/m2 level has been added to illustrate that other levels of radiative forcing than the four RCPs may also be explored
