One UN for multi-level Climate Action: Unlocking Finance and Implementation for NDCs and NAPs

2025 marks a pivotal moment for climate action. As countries prepare updated NDCs and advance their NAPs, the opportunity to align policy ambition with practical action has never been more urgent – or more achievable. Yet, persistent financing gaps, policy fragmentation, difficulties accessing data, and capacity constraints continue to hinder progress.

This session, co-led by UNU and UN-Habitat in partnership with UNDP, UNCDF, UNFCCC, UNEP, UNDRR, and WHO, focuses on how countries can enhance shaping and implementing NDC and NAP priorities through strategic alignment and south-south exchange.

The discussion is structured in three rounds. First, participants will identify gaps and opportunities for financing climate action through NDCs and NAPs, with inputs from relevant stakeholders. Secondly, the focus will shift to multilevel implementation in and with subnational governments, showing how NDC 3.0 processes can drive integrated solutions that address resilience, housing, health, and equity. Third, speakers will look ahead, highlighting solutions and innovative approaches to unlock climate implementation and scale impact.

Through concrete examples from diverse regions, the session will highlight scalable solutions, such as climate risk insurance, urban resilience solutions, multilevel and multisectoral governance mechanisms, and locally led projects.

This session speaks directly to COP30’s call to deliver climate solutions for the Global South by advancing inclusive, locally grounded, and financeable climate actions.
