A 2030 plan for the action agenda should, consistent with the Fourth Letter of the incoming Presidency for the 30th Conference of the Parties (COP30) to the UN Framework Convention on Climate Change (UNFCCC), facilitate follow-up on the outcomes of the first global stocktake (GST) and enhance international cooperation in support of the Paris Agreement five-year ambition cycle. It should also stabilize and streamline a unified approach to better inform the work of Parties and send signals through to 2030. In that context, this discussion paper sets out key recommendations for a Climate High-Level Champions’ (CHLC) five-year plan, including fostering accountability for GST-aligned solutions for the implementation of climate and development priorities, led by international cooperative initiatives.
