	The existing model structure is highly generic, with macroeconomic developments driving emissions, which, in turn, cause damages to the economy. The model considers non-CE emissions mitigation interventions dependent on a variable carbon price which is derived from the MAC curve, calibrated against AR6 data. In a given year <math>t</math>, baseline emissions are reduced based on a reduction factor derived from the MAC curve: <math>emissions_{t}=baseline_{t}*reduction_{t}</math> . Mitigation cost are calculated for the chosen carbon price and reduction factor.

	Being a global and highly abstract model, the {{abbr\|Circular Economy\|CE}} extensions currently discussed for implementation are of a broader perspective as well. A simpler option of the solution space would not distinguish any value retention strategies (R strategies) but estimations of direct impacts from industry circularity/material efficiency measures on emissions mitigation. If model development allows for more advanced solutions, we would aim for up to three high-level {{abbr\|Circular Economy\|CE}} measures: reduce ([[Reduce (R2)]]), prolong, recycle (prolong might implicitly contain repair, reuse and refurbish strategies).

	Increasing global population and wealth have led to a rapid rise in material consumption, causing resource depletion and waste generation, as well as high levels of energy use and related greenhouse gas (GHG) emissions from the production and use of materials. The circular economy (CE) has been proposed as an alternative to the linear economic model and aims to reduce primary material consumption and material wastes by narrowing loops, slowing loops, and closing loops. The potential of {{abbr\|Circular Economy\|CE}} and material efficiency strategies for GHG emission reductions (related to {{abbr\|Sustainable Development Goal\|SDG}} 13) has been highlighted in several scientific publications. It is believed that reducing material consumption through {{abbr\|Circular Economy\|CE}} strategies could play an essential role in meeting climate targets. While cost-benefit ~~integrated assessment models~~ (IAMs), such as DICE, are used to assess climate policy strategies by determining cost-optimal GHG emission reduction pathways, they do not represent material stocks and flows nor the impact or potential of {{abbr\|Circular Economy\|CE}} strategies for climate change mitigation pathways.

	In this project, we address this gap by further developing MIMOSA, a simple and transparent cost-benefit IAM covering relevant technological and socio-economic (yet no material or {{abbr\|Circular Economy\|CE}}) dynamics similar to DICE, towards a global meta-model that describes the key dynamics in which {{abbr\|Circular Economy\|CE}} strategies impact climate change mitigation efforts. MIMOSA has been developed and used in existing research to examine the interaction of the most significant factors, such as socio-economic developments, climate system uncertainty, damage estimates, mitigation costs and discount rates. We build on and aim at extending the existing model by integrating a novel ‘stylized’ energy, material and {{abbr\|Circular Economy\|CE}} modelling component. To achieve this goal, we intend to leverage the global climate and resource databases of IPCC and IRP, as well as other material/CE modelling data from existing research. Depending on data availability, we aim to decompose the existing model's mitigation component to include energy and material intensities. Material stocks and {{abbr\|Circular Economy\|CE}} measures will be represented in a global generic material model. Furthermore, these dynamics will be assessed across developed, emerging and developing world regions and many broad sectors (such as industry, transport and buildings). Implementing these dynamics in climate mitigation models will allow policymakers to build upon scenarios and insights into optimal pathways to meet Paris Agreement targets, distinguishing newly introduced {{abbr\|Circular Economy\|CE}} measures from more traditional measures for climate mitigation.
