The outcome of the Paris Agreement established the Global Goal on Adaptation (GGA), not as a quantitative goal but as a shared aspiration. The GGA will be one of the goals against which the global stocktake (GST) will assess collective progress.

Several different formulations for an overarching goal have been proposed formally and informally through the GlaSS programme and related discussions. In this brief, some of these proposals will be explored while highlighting their benefits, drawbacks, and considerations. The brief concludes by looking at how Parties can work toward the successful adoption of a GGA framework from now through COP28.
