Assessing transboundary climate risks under the UNFCCC Global Stocktake

Transboundary climate risks remain lacking from the UNFCCC Global Stocktake (GST); actions must be taken now and for the next GST to address this gap.The GST is the primary international mechanism to systematically track global progress towards the goals of the Paris Agreement, including the goal on adaptation. The process should enable countries and stakeholders to understand collective progress and gaps. As the first GST concludes at COP28, the outputs of the process should explicitly recognize that an important part of the picture is missing. This moment also represents an opportunity to assess the barriers to systematically track global progress in building resilience to transboundary risks.
