Advancing adaptation action: Enhancing alignment between national adaptation plans and nationally determined contributions

In anticipation of the 2025 update to the nationally determined contributions (NDCs) under the Paris Agreement, this briefing note synthesizes a review of countries that have submitted an NDC and a national adaptation plan (NAPs) and assesses the extent of alignment of the adaptation-related information presented in these documents. 

Targeted at national-level policy-makers-especially NAP teams who are responsible for a country's national adaptation planning and implementation-this briefing note emphasizes the NDC update in 2025 as an important opportunity to further enhance alignment between the NAP process and NDC. It provides practical steps, guiding questions, and examples of good practices from countries on how to realize these complementary linkages for more effective, inclusive adaptation.
