Call for abstracts

Abstract submissions are now closed.

The IAMC solicits abstracts for oral and poster presentations on the following selected research topics:

1. NATIONAL – Assessment of national mitigation strategies (including non-state actors). This session will focus on assessing the effectiveness and consequences of climate policies at the national scale, including the implementation of nationally determined contributions, net-zero targets and mid-century strategies. The session can also cover the contribution of non-state actors.

2. INTERNATIONAL – International climate policy.
This session focuses on the implementation of international climate policy in the context of UNFCCC, including the use of flexible instruments (Art. 6).

3. DEEP – Analysis of deep mitigation strategies.
This session will focus on (the consequences of) mitigation scenarios aimed at stringent mitigation targets consistent with the Paris Agreement.

4. OVERSHOOT – Strategies to decrease warming after an earlier peak.
This session will look at possible overshoot strategies, including the possible climate impacts of overshoot.

5. GEOPOLITICS – How does the (current) geopolitical situation influence climate policy.
This session looks into how the current geopolitical situation influences climate policy and discusses possible ways forward. Moreover, it also looks into the relationships between trade and climate policy and considerations related to security.

6. DEMAND – Efficiency, lifestyle change, sufficiency and regrowth.
This session will focus on modelling energy demand and the role of efficiency improvement. Attention will also be paid to the role of behavioral change, degrowth and its representation in IAM models. Finally, submissions may investigate the consequences of digitalization and AI.

7. TRANSPORT & BUILDINGS – Integrated assessment of pathways to carbon neutrality in the transport and building sector.
This session will look into decarbonization strategies for the two sectors, including changing mobility and housing services, improving energy efficiency, electrification, and low carbon fuel substitution.

8. INDUSTRY – Industry and Circular Economy.
Integrated assessment of pathways to carbon neutrality and circularity in industry, including in-depth analyses of industry sub-sectors and considerations of circular economy and material efficiency. Studies on changing supply chains during the transition, including associated risks and opportunities, are also invited for submission to this session.

9. ENERGY – Energy supply-sector analysis (including fossil fuels).
The section will investigate the advanced analysis of electricity and hydrogen production (including system integration) and the use of these energy carriers in end-use sectors.

10. CDR – Carbon dioxide removal and nature-based solution.
This section looks into promising carbon dioxide removal techniques (CCU, BECCS, DACS, and others) and the implications of using these.

11. LAND – Land, agriculture, and forestry.
This session will focus on strategies related to land-related sustainable development problems, including biodiversity conservation, land degradation and climate change.

12. FEASIBILITY – Feasibility and transition analysis.
This section will focus on the representation of socio-technical transitions in IAM research (including institutional change) and issues related to feasibility. Specifically, it will address how to combine insights from social-technical transition research, insights on institutional change and governance and IAM modelling. One of the relevant topics here can be dealing with different forms of feasibility (technical, economic, and social or political), enablers of effective climate policy and barriers.

13. ECONOMY – Economic analysis and climate finance.
This section focuses on the economic aspects of mitigation and adaptation strategies and risks associated with climate impacts. This also includes climate finance. But also integrated approaches to mitigation, adaptation, and impacts together. 

14. IMPACTS – Impacts of climate change (including representation of the climate system).
This session will focus on modelling climate impacts in integrated assessment models. Special attention will be paid to the representation of adaptation in IAMs. Impacts of climate change, such as those on agriculture, energy systems or wider. The session will also look into the representation of the climate system itself (including small climate models and emulators).

15. BIODIVERSITY – Modelling biodiversity and ecosystems services.
This session will look into the use of IAMs for assessing trends in biodiversity and the provisioning of ecosystem services. 

16. CITIES – Cities and climate mitigation, adaptation and impacts.
This session will look into the possible impacts of cities on climate change and their role in mitigation and adaptation. The session will also consider climate impacts on cities.

17. CLIMATE – Representation of climate, air pollution and carbon cycle in IAMs.
This session discusses the representation of climate and air pollution in IAMs, but also specific strategies to deal with air pollution and forcing from short-lived climate forces.

18. DISRUPTIONS – Representation of possible disruptive events in models and scenarios.
In most cases, IAMs focus on gradual trends in human activities and the earth system. Disruptive events, however, may have significant impacts on the future. This session will focus on the representation of possible disruptive events in models and scenarios.

19. WELLBEING – Human wellbeing and health.
This session will focus on the representation of human wellbeing and health in IAMs.

20. SUSTAINABLE – Sustainable development.
This section will focus on the assessment of Sustainable Development Strategies, including scenarios aiming to reach multiple SDGs and analysis of the energy-water-land nexus.

21. JUSTICE – Climate justice (including equity and distributional impacts).
Analysis of distributional aspects of mitigation strategies (both at the international and national scale) and the development of just transition strategies. The support for mitigation strategies often depends on the (perceived) fairness of strategies. In this session, we will look into the distributional and fairness aspects of mitigation strategies related to IAM analysis.

22. CRITICAL MATERIALS – Critical minerals and materials (CMMs).
The energy transition will require demand of all kinds of (critical) materials. This session will look into this relationship and possible consequences for the energy transition.

23. POLICY – Policy instruments and policy analysis.
This session will focus on the representation of policies in IAMs and the analysis of the impact of different policy instruments.

24. METHODS – Methodological advances in IAM research (including use of AI, open science and stakeholder interaction).
This session will specifically look at various methodological issues related to IAMs, including open science and uncertainty analysis. This may also involve model validation, programming languages presentation tools, model solvers, representation of complex policies and model evaluation.

25. SSPs – SSPs and other scenarios.
This session is looking for updates and extensions of the SSP scenarios in various areas and across scales, such as developing national and regional scenarios and their association with appropriate SSP domains. At the same time other new scenarios and focus on the representation of shocks are also welcome.
