Periodic Reporting for period 2 - IAM COMPACT (Expanding Integrated Assessment Modelling: Comprehensive and Comprehensible Science for Sustainable, Co-Created Climate Action)

Berichtszeitraum: 2024-03-01 bis 2025-08-31

Zusammenfassung vom Kontext und den Gesamtzielen des Projekts

-Efforts not on track to meeting the Paris goals; international cooperation still limited
-Modellers insufficiently including non-scientists, despite need for wide societal support
-LMICs not “owning” their NDC commitments (modelling often outsourced)
-Modelling predominantly on supply side, despite potential in demand and behaviour
-IAMs mostly designed for long-term horizons and ill-equipped for deep uncertainties or structural changes
-Climate action typically assessed outside the sustainability spectrum
-Interdisciplinary transitions research agenda needed for feasibility & desirability
-Mitigation pathways often assessed against unrealistic baselines

Objectives included:
O1|Supporting the assessment of global climate progress, needs, and feasibility, and the preparation of national policies for the post-2030 period, toward mid-century climate neutrality
O2|Placing climate action in a holistic sustainable development framework
O3|Enhancing the robustness of scientific outputs and incorporating social, political, behaviour, and innovation insights in models
O4|Co-creating policy-relevant modelling via an international policy response mechanism
O5|Establishing an integration process that co-produces science and policy prescriptions by adding layers of tools, models, methods, and bodies of knowledge
O6|Opening the ‘black box’ of scientific inputs, processes and outputs
O7|Engaging in the deep/extreme uncertainty space
O8|Boosting international cooperation, partnership, and capacity

Arbeit, die ab Beginn des Projekts bis zum Ende des durch den Bericht erfassten Berichtszeitraums geleistet wurde, und die wichtigsten bis dahin erzielten Ergebnisse

(a) Listening
Policy Response Mechanism (PRM) established
Database of 5,759 stakeholders (> 500 academia, 500 business, 500 industry, 500 civil society, 250 modellers, 200 social scientists, 2000 policymakers, 100 LMICs)
24 Policy Steering Groups (62 policymakers) to co-define questions
13 Core Working Groups (192 stakeholders) to co-design scenarios
14 policy briefs

(b) Exchanging

(c) Modelling
Policy catalogue, model coordination, data/policy harmonisation, broad scenario protocols
Global & regional mitigation analyses (EU, India, China, USA), sectoral & sub-national deep dives in Europe

(d) Expanding
Open database & model inter-comparison on COVID-19 recovery packages
Microsimulation & macroeconomic modelling of distributional impacts
