Five shared socioeconomic pathways (SSPs) representing different combinations of challenges to mitigation and to adaptation
Five shared socio-economic pathways (SSPs) representing different combinations of challenges to mitigation and to adaptation.

< Back to SPEED overview

Shared Socioeconomic Pathways (SSPs) describe a set of alternative plausible trajectories of societal development, which are based on hypotheses about which societal elements are the most important determinants of challenges to climate change mitigation and adaptation. SPEED has been working with partners to develop UK versions of the SSPs through a participatory process involving stakeholder workshops, interviews and questionnaires to spatially, temporally and sectorally extend global and European versions of the SSPs.

The UK-SSP products are available to 2100 and comprise:

  1. narratives of socio-economic developments for the UK and four UK nations
  2. system diagrams that visualise the interrelationships between socio-economic drivers within each SSP
  3. tables of semi-quantitative trends in 50 key socio-economic variables
  4. spatially-explicit quantitative projections for key socio-economic variables.

The UK-SSPs products have been jointly developed with Cambridge Econometrics, University of Edinburgh and University of Exeter through co-funding from the Met Office as part of the UK Climate Resilience Programme (DN420214 – CR19-3).

Semi-quantitative trends

This document provides semi-quantitative trends for 50 socio-economic variables within each UK-SSP. Trends are categorised into seven categories (very strong increase, strong increase, slight increase, no change, slight decrease, strong decrease, very strong decrease) across three time periods up to 2100.
