This issue brief reviews ways to make the GST most effective within the confines of the structure already negotiated. It builds on publications under the Independent Global Stocktake (iGST)—a collaborative effort by climate modelers, analysts, campaigners, and advocates that aims to support the GST process. It was prepared on the basis of a multiyear research effort by multiple organizations under the iGST’s “Designing a Robust Stocktake” discussion series, which analyzes the GST from a variety of angles, such as mitigation, adaptation, finance, and equity. The publications in this series were produced through targeted interviews, webinars, written feedback, and direct inputs.
