Usage in publications, projects, and tools
This page contains information on usage and applications of the MESSAGEix framework in academic publications and research projects. It also lists tools that have been developed by researchers beyond the IIASA ECE program to extend or complement MESSAGEix.
Because the model formulation is flexible, users (individuals and groups) of MESSAGEix have built a wide variety of concrete models to study research questions in a range of domains and fields. Model outputs are also used in a variety of ways, notably to inform policy-makers and other stakeholders facing energy systems challenges and decisions.
The list is not exhaustive, but provided to illustrate the wide range of possible applications of MESSAGEix for current and prospective users, and also to encourage knowledge exchange within the MESSAGEix user community.
To add your publication, tool, or project to this page, see Sharing publications, projects, and tools.
The following is a selection of academic publications in which MESSAGEix was used to carry out energy systems research. For each, the spatial scope/resolution, keywords and specific usage of MESSAGEix are described.

ixmp provide a robust feature set for modeling.
However, these features are general-purpose, so some users have developed additional tools that extend or complement MESSAGEix to serve specific use-cases or needs.
It is not guaranteed that the tools listed in this section are maintained.
