UN Climate Change News, 13 June 2025 – The UNFCCC secretariat has released a new synthesis report consolidating experiences, progress, best practices and remaining challenges faced by Parties in preparing their Biennial Transparency Reports (BTRs) and implementing the Enhanced Transparency Framework (ETF) under the Paris Agreement.

The report draws on views shared by Parties and on the first BTR submissions by developing countries, and will inform the upcoming Facilitative Dialogue taking place during the June Climate Meetings in Bonn.

The Facilitative Dialogue will provide a platform for Parties and stakeholders to reflect on the content of the synthesis report and enable an exchange on successes, lessons learned and challenges faced during BTR preparation. The dialogue will inform future capacity-building and support efforts and strengthen national systems for climate reporting.

“Transparency is not just about reporting – it's about enabling national transformation and ensuring the Paris Agreement delivers results,” said UN Climate Change Executive Secretary Simon Stiell. “This Facilitative Dialogue will be a key moment to share, learn and move forward together.”

Key findings from the synthesis report

The synthesis report captures the growing momentum among developing country Parties in climate reporting, while acknowledging challenges that require sustained international support and cooperation. Key observations include:

• Transparency drives ambition: BTRs are helping countries not only comply with reporting requirements but also inform national planning, policymaking and investment.
   
• Support received is delivering results: Many developing countries highlighted the critical role of technical assistance received from the Consultative Group of Experts (CGE), UN bodies and partners in preparing their first BTRs.
   
• Peer learning accelerates progress: Regional cooperation and peer exchanges have proven valuable in addressing technical challenges and enhancing national reporting systems.
   
• Challenges persist: Data gaps, coordination issues and limited institutional capacity remain common hurdles. Continued, tailored financial and technical support is needed.
   
• Rate of progress is diverse, but with meaningful outcomes: Despite differing starting points, all countries are building solid foundations for stronger reporting and continuous improvement.

Ongoing support provided by the secretariat

To support developing countries in implementing the ETF, UN Climate Change scaled up technical support activities between January and May 2025, including:

• 17 country-specific support events (online and in-person), reaching 319 national experts.
   
• 11 regional workshops, involving 373 experts from 112 developing countries.
   
• Certification of 1,700 review experts through the BTR Technical Expert Review training programme.

Register for the Facilitative Dialogue

The event will take place on 18 June and is open to all delegates, with particular encouragement for national focal points and transparency experts to attend. You can register for the event here.

It will feature remarks by the COP29 Presidency (Azerbaijan) and the incoming COP30 Presidency (Brazil) and conclude with closing remarks by UN Climate Change Executive Secretary Simon Stiell.

What’s Next?

Insights from the synthesis report and outcomes of the Facilitative Dialogue will inform the Dubai–Baku Transparency Workplan and guide ongoing transparency support activities in the lead-up to COP30.
