Abstract:

Integrated Assessment Models (IAMs) have played a significant role in the global and national processes of addressing climate change, especially in all the assessment reports of the Intergovernmental Panel on Climate Change (IPCC), supporting the evaluation and formulation of global emission reduction targets. The development of IAMs themselves has gone through stages from highly synthesized models to large-scale complex models. With the CO₂ emissions of countries committed to carbon neutrality accounting for the majority of global CO₂ emissions, the research direction of IAMs also needs to undergo major adjustments, shifting from the original focus on assessing scenarios and pathways for temperature targets to more detailed studies of economic sectors, technologies, and related economic and ecological environmental factors, in order to support the understanding and formulation of the paths and policy measures for energy and economic transitions under the goal of carbon neutrality. The transition of IAMs research needs to be advanced as soon as possible and requires the participation of more academic research groups.

Key words: Climate change, Mitigation, Integrated Assessment Models (IAMs), Policy making
