shared socio-economic pathways

Shared Socio-economic Pathways (SSPs) describe alternative socioeconomic futures in the absence of climate policy intervention, comprising sustainable development (SSP1), regional rivalry (SSP3), inequality (SSP4), fossil-fuelled development (SSP5) and middle-of- the-road development (SSP2). The combination of SSP-based socio- economic scenarios and Representative Concentration Pathway (RCP)-based climate projections provides an integrative frame for climate impact and policy analysis.

Narratives outlining broad characteristics of the global future and country-level population, Gross Domestic Product (GDP), urbanisation projections based on five alternative socio- economic developments (i.e. sustainable development), regional rivalry, inequality, fossil-fuelled development, and middle-of-the- road development. The SSPs are supported by key quantitative indicators and metrics, describing trends in demographics, human development, economy and lifestyle, policies and institutions, technology, environment and natural resources.
