The Implementation Forum

The Implementation Forum will take place on 3 and 4 September and will feature a series of events. Over the course of the two days, the Forum will include, among others, the Climate Week Opening Ceremony; a number of events hosted by the COP 30 Presidency, including the  events on“Mutirão”,climate action agenda and a mandated dialogue on advancing the role of local communities in the UNFCCC Process. Other sessions during the Implementation Forum will focus on climate finance and adaptation, for example the Adaptation Finance with a focus on Africa event and Public-Private dialogue on Finance. As in Climate Week 1 2025, a dedicated space will be created for the Implementation Labs, which will focus on thematic issues, such as forests, agriculture, sustainable cities, energy transition and access, and carbon markets. 

The thematic areas for ILabs have been identified building on the COP 30 Action Agenda’s key objectives, including a strong emphasis on equality and inclusion, particularly of underrepresented groups such as women, youth, Indigenous Peoples and local communities, and taking into account the priorities of the Africa Climate Summit 2025 taking place after the Climate Week to ensure continuity and complementarity. To ground these sessions in real-world action and meaningful collaboration, the UNFCCC secretariat is calling for real-world, implemented, replicable solutions to be showcased and presented in-person as “concrete kick-off examples” at the Implementation Labs. Importantly, these solutions will have the opportunity to feed into the COP 30 Action Agenda’s Granary of Solutions – with an aim to showcase relevant, scalable solutions aligned with the first Global Stocktake outcomes.

Mandated Events  

Each mandated event that took place during Climate Week was organized in accordance with its respective mandate under the Conference of Parties serving as the meeting of Parties to the Paris Agreement and Subsidiary Bodies.  

Nomination and registration procedures for each mandated event can be found in their respective communications to Parties, observer organizations, and UN/IGOs. 

Implementation Forum Day 

The Implementation Forum took place on Wednesday, 21 May, with a series of events and concluded with a plenary session on Thursday 22 May. It acted as a catalyst for bringing together key stakeholders, including governments, subnational governments, businesses, financial institutions such as multilateral and national development banks, civil society, and Indigenous Peoples, to identify actionable outcomes driving sustainable progress.

The labs served as a platform to foster multi-stakeholder engagement, facilitating discussions to identify actionable solutions to deliver implementation of NDCs around three main key means of implementation: finance, technology and carbon markets.

In addition to the Ceremonial Opening of Climate Week, a number of events were part of the Implementation Forum, including the COP30 Presidency special events, Enhancing NDCs Ambition for a Sustainable and Just Future event, and the implementation labs, among others. 

Implementation Labs

Finance Lab: The Finance Lab was designed to strengthen the understanding, design, and implementation of finance solutions for climate priorities, supporting the needs-driven delivery of Nationally Determined Contributions (NDCs) and National Adaptation Plans (NAPs). It focused on addressing policy and institutional barriers, enhancing enabling environments, locally led approaches, building technical and institutional capacity, and providing targeted technical assistance. The Finance Lab aimed to actively incorporate real-world success cases and lessons learned, engage participants through moderated discussions, and integrate direct feedback to iteratively refine support strategies. Finance is recognized as a critical enabler for the deployment and scaling of technologies. Additionally, innovative financial instruments are essential for mobilizing investment in mitigation and adaptation activities capable of generating internationally transferred mitigation outcomes (ITMOs) under the Paris Agreement Crediting Mechanism (PACM). By strengthening institutional capacities and improving enabling conditions, finance will support the implementation of Article 6-compliant projects and programs that contribute to achieving NDC targets while delivering adaptation co-benefits. Through its cross-cutting and practical implementation focus, the Lab seeks to bridge finance, technology, and market mechanisms, driving transformational climate action at scale.

Article 6 Lab: The Article 6 or Carbon Markets Lab served as a collaborative platform where governments, project developers, UN agencies, multilateral development banks, and private sector partners united to advance climate action through market-based approaches, specifically under the Paris Agreement Crediting Mechanism. By fostering dialogue among these stakeholders, the initiative shifted discussions from high-level policy debates to actionable strategies for implementation.
This practical focus equipped participants with insights into:
  •  Operational requirements for scaling climate projects
  •  Key compliance frameworks
  •  Effective risk management practices to maximize emission reduction outcomes
The Lab also prioritized knowledge-sharing and identifying capacity-building gaps across stakeholders. These insights strengthened coordination between multilateral institutions, public-private partnerships, and other support systems, ensuring tailored assistance for impactful, on-the-ground climate solutions.

Technology Lab: The Technology Lab addressed key topics to support NDC implementation. It delved into the role of emerging technologies like Water-Energy-Food/Agrifood systems, Industrial decarbonization, energy systems, AI for climate action while also recognizing the importance of practical, accessible, and affordable solutions for developing countries or sectors with limited technological infrastructure.

It included roundtables on:

• Water-Energy-Food nexus/Agrifood systems;
• Industrial decarbonization;
• Energy systems;
• Artificial intelligence for climate action.

Further, it focused on aspects related to capacity-building for technology development and transfer, and financing climate technologies, which builds upon the work of the Technology Mechanism.

The lab increased awareness of proven climate technology and innovation options that deliver accelerated adaptation and mitigation action across geographies and identified practical insights and actionable steps toward implementation.

Other important events that were part of Implementation Forum Day include:

• From Call to Mobilization: Bringing the Global Mutirão Framework to Life

The COP30 Presidency has called on the international community to come together in a global "mutirão" against climate change. This event provided a platform to clarify the concept, invite participation, and begin building the networks and narratives that will shape
the Mutirão’s global trajectory. By bringing the concept to life now, the COP30 Presidency demonstrated early momentum, explored the concept through concrete examples, and began engaging partners across geographies and sectors in co-creating a new model for action.

This event served as the public launch of the Global Mutirão pilot, an opportunity to explore the concept together, share early examples, engage aggregators and partners, and invite participants to contribute ideas and actions toward this emerging framework. Find more information here.

• The Future of Global Climate Action

The COP30 Presidency shared views on the Climate Action Agenda as it has developed since COP20 and presented ideas for COP30 and beyond, with a focus on the full implementation of the GST. The event was an opportunity for different stakeholders to gather information and share their perspectives to help shape ambitious and more inclusive climate action.

• Enhancing NDC Ambition for a Sustainable and Just Future

This event brought together high-level government representatives, policymakers, climate experts, and key stakeholders to explore how enhancing NDCs can drive inclusive and transformative progress. The event highlighted the role of NDCs in the green transition, decarbonization, and transformation of sectors, advancing resilience, and promoting social equity.

NDC Clinic 

Climate Week also hosted the first NDC Clinic of the year – an in-person, capacity-building event that provided practical support to participating countries through the exchange of knowledge and experiences in key areas critical for NDC implementation. These included assessing needs for NDC implementation, including accessing both public and private finance; strengthening investment planning and prioritizing investment needs; aligning NDCs with national policies and priorities; strengthening institutional capacities and inter-ministerial coordination; and enhancing stakeholder engagement, including with financial institutions, private investors, and other key stakeholders.
