From Ambition to Action: Unfccc Peer Exchanges Drive Global NDC Implementation

A key mandate contained in the Global Mutirão Decision adopted at COP30 is rapidly moving from policy into practice, as countries across the world gather to learn directly from one another on how to implement their national climate action plans. The decision tasked the UNFCCC secretariat with organising peer exchange workshops to enable countries share experiences, knowledge and good practices on the development and implementation of Nationally Determined Contributions (ND Cs). A peer exchange event dedicated to ND Cs.

That mandate is now gaining momentum. At least 22 NDC-focused peer exchange events have so far been held across the six regions covered by the UNFCCC secretariat and its Regional Collaboration Centres (RC Cs), spanning Latin America, the Caribbean, the Middle East and North Africa, Asia and the Pacific, West and Central Africa, and East and Southern Africa. More events are planned in the coming months, including a Pacific workshop ahead of pre-COP31 in October, a climate finance masterclass in Uganda and a finance-focused programme for Caribbean countries.

While the activities differ from region to region, they share a common objective: enabling countries to learn from one another and translate climate commitments into practical, coordinated and adequately financed action. A Global Mandate for Peer Learning. The Global Mutirão Decision adopted at COP30 requests the UNFCCC secretariat to facilitate peer exchange workshops through which countries can share knowledge and best practices on preparing and implementing ND Cs.

The initiative builds on paragraph 117 of Decision 1/CMA.5, which emerged from the first global stocktake under the Paris Agreement. The timing is particularly significant. The year 2025 marked the end of the first cycle of NDC ambition, with countries expected to submit more ambitious NDC 3.0 plans.

The challenge now extends beyond setting stronger targets to determining how those commitments can be translated into concrete, coordinated and financeable actions. For many countries, particularly developing nations, the implementation challenge is immense. This is where the UNFCCC secretariat and its Regional Collaboration Centres are increasingly creating platforms for governments to exchange practical experiences and learn from one another's successes and setbacks.

Six Regions, Different Challenges. One of the defining features of the initiative is the flexibility of the peer-learning model, with each region adapting exchanges to its particular climate, economic and institutional realities. In the Pacific, where 11 countries have submitted their NDC 3.0 plans, a major challenge is coordinating climate action across small and geographically dispersed island administrations.

Pacific governments meeting in Fiji in September are expected to explore how countries with limited resources can better coordinate implementation and engage international financiers. The discussions are strategically timed ahead of the pre-COP31 meeting scheduled to take place in the Pacific in October. In East and Southern Africa, attention has turned strongly towards climate finance.

An online peer masterclass on financing NDC implementation drew lessons from the Seychelles' experience in establishing a dedicated climate finance unit, while also highlighting opportunities for South-South cooperation involving countries such as Eswatini. West and Central Africa has taken a more sector-specific approach to the same broader implementation challenge. A peer exchange focused on rural electrification brought together governments from Togo, Burkina Faso and Cameroon in Dakar, where Senegal shared lessons from its solar-powered rural electrification programme.

Rather than leaving with broad recommendations, participating countries began developing tailored approaches informed by the practical experiences and lessons of their regional counterparts. Across the Middle East and North Africa, peer learning is taking a slightly different form. Countries still working to finalise their NDC 3.0 plans are being linked with governments that are already further advanced in implementation.

The approach allows countries to benefit from the experiences of others and potentially avoid challenges and mistakes already encountered elsewhere. Linking Experience with Finance. For Caribbean Small Island Developing States, peer exchange is increasingly being combined with direct engagement with potential financiers. Like their Pacific counterparts, Caribbean countries face challenges associated with small economies, high implementation costs and limited fiscal space.
