Integrated assessment models (IAMs) are commonly used by decision makers in order to deriveclimate policies. IAMs are currently based on climate-economics interactions, whereas the role of socialsystem has been highlighted to be of prime importance on the implementation of climate policies. Beyondexisting IAMs, we argue that it is therefore urgent to increase efforts in the integration of social processeswithin IAMs. For achieving such a challenge, we present some promising avenues of research based on thesocial branches of economics. We finally present the potential implications yielded by such social IAMs.
