The NGFS Phase 4 project aims to deliver on the need for regular updates and further evolution of the scenario set developed in phase 1-3 of the project. This includes (a) ambitious goals of expansion and the simultaneous increase of usability and (b) more inclusive and streamlined processes of scenario and data production and dissemination. This will be achieved by implementation of activities in four work packages: (1) User interaction, outreach and dissemination; (2) Transition scenarios: Sectoral granularity, annual updates, and expansion of scenario set; (3) Physical risks; (4) Closing the Loop:consistently linking physical risks and transition risks.
