After a decade of tracking real-world climate action, UN Climate Change has announced a major redevelopment of the Non-State Actor Zone for Climate Action (NAZCA) portal, marking a new phase of ambition and innovation.
A Central hub for climate action data
Unveiled at COP30 in Belem, the NAZCA Portal Redevelopment and Engagement Roadmap sets out plans to transform the platform into a modern, data-driven system. The upgraded portal will consolidate non-party stakeholder information covering mitigation, adaptation, resilience and means of implementation, reinforcing the UNFCCC secretariat’s role as a trusted custodian of climate action data.
From transparency to implementation
Originally launched at COP20 and formally recognised at COP21, the NAZCA portal has evolved into a key transparency tool for showcasing commitments, climate plans and progress from cities, regions, businesses and civil society. The redevelopment aims to align the portal with the UNFCCC Climate Data Hub, supporting stronger implementation of the Paris Agreement.
Digital innovation and AI-driven Insights
Planned enhancements include improved user experience, expanded data accessibility and advanced digital tools such as full data downloads, geospatial mapping and AI-driven insights. These features are designed to help stakeholders analyse trends, track progress and identify opportunities for climate action at scale.
Strengthening engagement through the NAZCA network
A new NAZCA Network will support engagement through workshops, outreach and partnerships, bringing climate action information closer to local and regional actors. Self-service systems and upgraded modules will enable subnational governments, corporations and cooperative initiatives to link their actions more clearly with national climate contexts.
Enabling higher ambition globally
By strengthening transparency, engagement and data integration, the redeveloped NAZCA portal is positioned to catalyse higher ambition, support investment and accelerate global climate action across mitigation, adaptation and resilience pathways.
