Abstract for: Towards Modelling (Pro-)Environmental Human Behaviour in Integrated Assessment Models from a Systems Approach

Integrated Assessment Models (IAMs), used for climate impact and mitigation assessments, face criticisms for their overly techno-economic representations of human systems, driven mainly by economic indicators. Our work seeks to address this weakness by working towards the inclusion of endogenous representations of human behaviour in IAMs. To that end, we aim to construct a system dynamics simulation model, of pro-environmental human behavior, that combines insights from theoretical frameworks with lived experiences. This approach involves both top-down abstraction of existing (environmental) psychological theories and bottom-up exploration through participatory modeling and literature review. The eventual integration of these streams aims to refine IAMs, ensuring a more nuanced representation of human behavior and facilitating more effective climate change mitigation strategies. This work is part of the EU-funded research consortium, WorldTrans: Transparent Assessments for Real People, and will contribute to the development of a global scale, publicly accessible IAM: FRIDA (Feedback-based Repository for IntegrateD Assessments).
