To broaden the space of climate change mitigation options and to include circular economy and material efficiency measures in IAM scenario analysis, we develop MESSAGEix-Materials module representing material flows and stocks within the MESSAGEix-GLOBIOM IAM framework. With the development of MESSAGEix-Materials, we provide a fully open-source model that can assess different industry decarbonization options under various climate targets for the most energy and emissions-intensive industries: Aluminium, iron and steel, cement, and petrochemicals.

This is the code, documentation, and datasets for version 1.0.0 of MESSAGEix-Materials module.

The GitHub branch where the model exists: 

The version can be updated upon the completion of the review of the main manuscript.
