Conference of the Parties serving as the meeting of the Parties to the Paris Agreement (CMA) 1 requested the Adaptation Committee (AC) to develop, with the engagement of IPCC Working Group II, draft supplementary guidance for voluntary use by Parties in communicating information in accordance with the elements contained in the annex to decision 9/CMA.1.

This supplementary guidance provides an overview of the guidelines for adaptation communications (adcoms) and related arrangements, and suggestions for applying the guidelines and for benefiting from the links between adcoms and other adaptation-related reporting arrangements under the Convention and the Paris Agreement. 

It should help Parties that are preparing adcoms and the information referred to in the annex to decision 9/CMA.1 to enhance the quality of reported information, reduce duplication in it and in the work required to prepare that information, and benefit from synergies with other planning, implementation and reporting arrangements for adaptation by guiding them towards the latest relevant resources.

The guidance has greatly benefited from feedback provided by Party representatives, practitioners and experts, including scientific experts from IPCC Working Group II, at AC meetings, a webinar for developing the guidance held on 30 June 2021, an expert meeting held on 22 March 2022, a meeting between lead authors of the contribution of Working Group II to the Sixth Assessment Report of the IPCC held on 27 June 2022, as well as in numerous other exchanges with stakeholders.
