🌍 New PNAS Perspective out now: “The power of bridging decision scales: Model coupling for advanced climate policy analysis” coauthored by Francesco Lamperti
Why this matters:
Climate outcomes emerge from micro → meso → macro decisions. Single-model approaches miss key feedbacks across these levels.
Coupling models can combine global pathways, economy-wide spillovers, and behavioral realism—supporting policies that are not only efficient but also feasible and equitable
What we show:
💸Finance & transition risk: IAM→ABM coupling links long-term decarbonization paths to short-term macro-financial stability.
🏠Household adaptation → macro impacts: Hard-linked CGE↔ABM traces how local constraints and choices scale up to GDP, jobs, and welfare.
🤝 Politics & pledges: IAM↔ABM endogenizes voter support and international negotiations to stress-test net-zero trajectories.
What’s next: Designing multiscale policy mixes, aligning macro trends with distributional impacts, exploring the mitigation–adaptation nexus, and pushing methods (incl. selective roles for AI/ML).

Notably, the innovative examples of successful model coupling presented in our Perspective distill the knowledge created and envisioned by several ERC teams: SCALAR (led by Tatiana Filatova at TU Delft), RIPPLE (led by Giacomo Marangoni at TU Delft), FIND ERC Project (led by Francesco Lamperti at Sant Anna Pisa, IT) and SPHINX (led by Tatiana Filatova at TU Delft)
