On 7 November 2023, the Network for Greening the Financial System (NGFS) published the fourth vintage of its long-term climate macro-financial scenarios for forward-looking climate risks assessments. The NGFS scenarios explore the transition and physical impacts of climate change over a long time horizon and under varying assumptions.
The NGFS scenarios have been updated to account for the latest GDP and population pathways, and the most recent country-level climate commitments as of March 2023.
Key changes to the scenarios include:
- The orderly scenarios now reflect climate policy delays and the energy crisis following the war in Ukraine.
- The modelling of acute physical risks has been enhanced with the inclusion of two more hazards (droughts and heatwaves) and increased geographical granularity.
- Two new scenarios have been developed:
- the “Too-little-too-late” Fragmented World scenario that illustrates the adverse consequences of delayed and divergent climate policy ambitions globally; and
- the “Orderly” Low Demand scenario that explores a Paris-aligned transition driven by substantial behavioural changes in which global warming is limited to 1.5°C.
- The Divergent Net Zero scenario has been discontinued.
The NGFS welcomes feedback from users on the scenarios to keep on improving them.
