The Initiative for Climate Action Transparency (ICAT) is proud to announce the release of its 2025 ICAT Impact Report. This report showcases the progress, milestones, and tangible impact of last year’s efforts to enhance climate action through transparency across the developing world.

As countries prepared to submit the third generation of their Nationally Determined Contributions (NDC 3.0) due in 2025, climate action transparency took centre stage in global climate efforts. ICAT played a significant role in advancing the NDC process, equipping countries with the capacity, tools, and resources needed to design credible climate action plans and back them with evidence-based policies. In 2025, over 40 ICAT country projects directly covered NDC updates and/or NDC tracking, with 22 countries confirming ICAT support in the development of their NDC 3.0 or explicitly mentioning ICAT in the NDC submission. 

ICAT in 2025 by numbers:

• 15 new country projects initiated, including five in newly engaged countries
• 10 new countries applied ICAT guides, tools, and methodologies
• 1,582 people trained (44% women)
• 94% of training survey respondents (from trainings that took place in 2025) rated the training experience as ‘very good’ or ‘good’ 
• 10 countries that submitted reports in 2025 confirmed the ICAT project resulted in improved reporting to the UNFCCC or mentioned ICAT in the submission
• 22 countries confirmed ICAT support in the development of their NDC 3.0 or explicitly mentioned ICAT in the NDC submission
• 37 countries worked on establishing an NDC tracking framework
• 14 countries worked on establishing a greenhouse gas inventory
• 37 countries worked on establishing a Measurement, Reporting, and Verification (MRV) framework and/or data system
• 30 countries worked on assessing greenhouse gas and/or sustainable development impacts of sectoral policies
• 16 countries worked on building a framework to analyze projections of greenhouse gas emissions and removals
• 2 countries worked on developing monitoring frameworks for just transitions
• 11 countries worked on developing the Monitoring and Evaluation (M&E) of adaptation actions and/or loss & damage-related data
• 6 countries worked on building a climate finance transparency framework
• 7 countries worked on aggregating or integrating greenhouse gas impacts of subnational and non-state actions

By supporting countries to build strong and comprehensive transparency frameworks, ICAT helps create the foundations for transformational climate action. Such transparency efforts strengthen trust and support evidence-based policy processes for implementing NDCs, enabling developing countries to engage stakeholders domestically and be empowered as actors in the multilateral process, contributing to the success of the Paris Agreement. –Dr. Ursula Fuentes, Head of Division – UNFCCC and Paris Agreement, International Negotiations at the German Federal Ministry for the Environment, Climate Action, Nature Conservation and Nuclear Safety

We extend our gratitude to our donors and partners, including partner countries, for making this progress possible.
