Integrated assessment model diagnostics: key indicators and model evolution

Article - July 27, 2021

In this article we build on previously developed approach to diagnose Integrated Assessment Models (IAMs) by proposing a selected set of well-defined indicators to systematically assess IAM behaviour, similar to metrics used for other modeling communities such as climate models. These indicators are the relative abatement index, emission reduction type index, inertia timescale, fossil fuel reduction, transformation index and cost per abatement value. We show that together, the set of six indicators can provide useful insights on the main traits and behavior of the model.
