SSP Scenario Database

The Shared Socioeconomic Pathways (SSPs) will be used alongside the Representative Concentration Pathways (RCPs) to analyze the feedbacks between climate change and socioeconomic factors, such as world population growth, economic development and technological progress.  IIASA began work in 2011 on quantifying one of the five SSPs. The Energy Program has spearheaded the cross-program collaboration with the Population and Ecosystem Services Management programs. More
