Reusable toolkit for sophisticated modeling related to refrigerants and other substances controlled under the Montreal Protocol and the Kigali Amendment. Supporting one of the most successful environmental treaties in human history, this open source platform democratizes access to cutting edge techniques that can help measure business as usual and impacts of potential interventions.

These are some of the most potent greenhouse gasses out there and Kigali Sim helps countries explore what things look like if no action is taken and what might happen under different policy schemes. In addition to helping nations explore their options, this software may also help prepare plans as required to access international funds like through the UN MLF.

Co-created with over a dozen nations and supporting organizations. Uses a domain specific language available through a programming portal as well as a UI-based editor which are interoperable, allowing for user-centered design innovation on multi-modal authoring. Finally, AI-enabled through llms.txt.

Software free and open source, available online at KigaliSim.org. Publication currently in process.
