The SSP5 scenarios mark the upper end of the scenario literature in fossil fuel use, food demand, energy use and greenhouse gas emissions. The SSP5 marker scenario results in a radiative forcing pathway close to the highest Representative Concentration Pathway (RCP8.5).. An investigation of mitigation policies in SSP5 confirms high socio-economic challenges to mitigation in SSP5. In SSP5, ambitious climate targets require land based carbon management options such as avoided deforestation and bioenergy production with CCS. The SSP5 scenarios provide useful reference points for future climate change, impact, adaption, mitigation and sustainable development analysis.
