UN Climate Change News, 23 February 2026 - Global climate transparency entered a new phase with the launch of the Climate Data Hub, a centralized platform that - for the first time - consolidates climate data from more than 190 countries in one place, offering critical insight into progress, gaps, investment flows and support needs - insight essential to turning climate ambition into real-world outcomes in this new era of implementation.
Developed by UN Climate Change in partnership with Microsoft, EY and NEDAMCO Africa, the Climate Data Hub provides reliable, official climate data that is easier to access, analyse and use, for all stakeholders - from government leaders and policy-makers, to investors and other real economy implementors, to academia and civil society groups.
"Climate data and transparency enable countries to identify needs, set priorities, and assess progress," said Xuehong Wang, Director of Transparency at UN Climate Change. "Through this new Hub, climate data becomes more than numbers. It becomes knowledge and insights, collaboration and opportunities to drive implementation and real-world results with vast benefits for peoples, governments and economies."
The Hub is now operational in its first phase, providing public access to financial, technical and capacity-building support data submitted under the Paris Agreement's Enhanced Transparency Framework (ETF). Future updates will expand the platform's functionality and integrate additional data sources as global needs evolve.
Climate data submitted under the UNFCCC and the ETF has long been abundant but difficult to compare, as countries reported in different formats. This complexity made it harder for policymakers, researchers, civil society and other climate stakeholders to track progress, analyse trends, and draw meaningful insights.
The Climate Data Hub is designed to address this limitation by applying advance analytics, artificial intelligence, and user-friendly design to make it easier to transform information submitted under the UNFCCC and the ETF into clear insights and visualisations. It is built in line with strict UN data governance standards to ensure security and integrity.
New opportunities for all stakeholders
The Climate Data Hub unlocks new potential for policymakers, business leaders, investors, researchers, development agencies, civil society, and the public. Its interface enables users to explore official data through simple queries, improving their ability to integrate evidence-based climate insights into planning, research and action.
For policymakers, the platform offers a clearer picture of national and sectoral progress over time, enabling governments to assess policy pathways and identify the most effective strategies - all grounded in official data.
For researchers, the Hub provides immediate access to harmonised datasets that can strengthen climate studies, modelling efforts and long-term assessments.
The Hub will also help investors, business leaders, support providers, development agencies, civil society organizations, and others working to advance climate action.
"The UNFCCC Climate Data Hub tackles a core challenge: climate data is often fragmented, difficult to compare, and manually processed," said Melanie Nakagawa, Chief Sustainability Officer at Microsoft. "Together with partners, we have built an AI-enabled, centralized platform that streamlines data management and strengthens transparent tracking of climate action. This is the kind of technology that helps turn data into action, and we're excited to see how governments, civil society, industry, and investors use it to accelerate progress."
Transparency beyond reporting
Transparency equips governments and real-economy implementers with the data to strengthen climate policy-making over time, identify investment needs and opportunities helping to mobilize more finance, and deliver faster and wider progress with more benefits for people, businesses and economies.
"Centralising and enhancing our climate data systems is not just a technical upgrade - it's a strategic move to empower governments and all other implementers to boost data-driven climate actions and deliver real-economy outcomes, in this new era of implementation," said Wang.
