SDSN Global Climate Hub Decision Support Navigator An open platform for systems transformation
The GCH approach / Stages 01 — 05
Vision

A Global Commons for systems transformation.

An open, accessible digital platform that couples integrated modelling, data infrastructure and stakeholder co-design — to translate systemic evidence into coordinated, country-specific action toward the SDGs.

  • Convergent crises require systems-level coordination, not sector-by-sector analysis.
  • Entry points and levers should emerge from measurement — not be assumed in advance.
  • Replicable methodology, not a universal prescription.
Step 01

Continuous monitoring & assessment.

A living evidence base. Coupled data infrastructures and digital twins that quantify the country-specific feasible space — the binding biophysical, economic and social constraints.

  • Earth observation × in-situ sensors × administrative data.
  • Indicators tracked at the same granularity as policy is made.
  • Outputs: feasibility envelopes used to calibrate Step 02.
Step 02

Co-designed transformation pathways.

Integrated modelling chains coupled with structured stakeholder engagement. Pathway design is an iterative dialogue between models, communities and decision-makers.

  • WEF nexus: water, energy, food & land coupled with macroeconomy.
  • Beyond-GDP CGE with ecosystem services valuation.
  • Living-lab validation by stakeholders before scenarios go public.
Step 03

Aligned financing & governance.

A reformed global financial architecture in which capital flows to country-validated pathways — and where ecosystem services are priced into macroeconomic decisions.

  • Sovereign & concessional finance aligned to pathway milestones.
  • Ecosystem services valuation embedded in CGE.
  • Transparent accountability to keep transitions on track.
