The Global Goal on Adaptation (GGA) now has a set of indicators to track progress—the Belém Adaptation Indicators. The indicators are intended to measure progress toward the GGA targets and inform the second global stocktake (GST2) that begins in November 2026. However, political and technical challenges persist. Concerns remain regarding the transparency of their adoption at the 30th Conference of the Parties (COP30), as well as their credibility, usability, and scientific robustness. Follow-up technical processes will commence in 2026 to further operationalize the indicators, primarily through the launch of the Belém– Addis Vision on Adaptation. Parties will also need to determine whether and how the indicators should be incorporated into broader GGA processes in 2026.
