to complement the Representative Concentration Pathways . By design, the RCP emission and concentration pathways were stripped of their association with a certain socio-economic development. Different levels of emissions and climate change along the dimension of the RCPs can hence be explored against the backdrop of different socio-economic development pathways  on the other dimension in a matrix. This integrative SSP-RCP framework is now widely used in the climate impact and policy analysis literature , where climate projections obtained under the RCP scenarios are analysed against the backdrop of various SSPs.
