First BTR synthesis report shows countries Paris Agreement with practical real-world actions

Below is a statement from UN Climate Change Executive Secretary Simon Stiell on the launch of the BTR Synthesis Report, released on 31 October 2025.

This first Synthesis Report of Biennial Transparency Reports marks another milestone in the implementation of the Paris Agreement.

The submission of over 100 Biennial Transparency Reports is a clear sign that Parties are very actively starting to implement the Paris Agreement, with practical real-world actions, across economies and societies.

Based on the first Biennial Transparency Reports from 109 countries, where data are available, this UN Climate Change synthesis report provides a valuable initial picture of countries’ varied progress on the basis of information and data reported up until 2022.

It shows that climate actions are being implemented in a systematic way, and driving real-world progress, but must be broadened and accelerated.

Across every region, countries are putting the Paris Agreement into action – through stronger policies, new institutions, and whole-of-society approaches that are driving change in the real economy.

From renewable energy to electric vehicles, from energy efficiency gains to reforestation and emission trading schemes, to growing attention on adaptation as part of climate change strategies, the evidence is clear: the transition is well under way, but must now speed up and scale up urgently.

The report shines a light on factors driving success, and factors that are holding back faster progress.

Several crucial enablers emerge clearly. More and higher quality finance needs to flow where it’s needed. Strong data and transparency systems are vital. And inclusive, just transitions are crucial to ensure far more people share in the vast human and economic benefits of stronger climate actions, in a fast-changing world.

Several barriers are equally clear, including capacity and data gaps, and a persistent shortfall in finance and technology support for developing nations.

Given this report reflects information and data reported up to 2022, substantial further progress can be expected to have been made on wide-ranging fronts. Our new reports on National Adaptation Plans and Nationally Determined Contributions in recent weeks point to many relevant areas of progress, particularly the increasing evidence of whole-of-economy, whole-of-society climate planning and policy-making, and improving implementation.

The findings from this first Synthesis Report suggest that future reports will show stronger progress – with countries strengthening their transparency systems, expanding the volume and reliability of data, and receiving more targeted capacity building support. These initial reports mark the beginning of a new era of enhanced transparency that will enable more informed decision-making and data-driven climate action.

Looking more immediately ahead, this report provides valuable insights ahead of COP30 in Belem, which will be the world’s moment to respond, and pick up the pace, in this new era of implementation.

COP30 must also send a clear global signal: that nations are unwavering in their commitment to climate cooperation under the Paris Agreement, with strong and concrete outcomes across all key issues.

And it must connect climate action to real lives everywhere, to help spread the vast benefits of climate action to far more people: stronger economies, more jobs, better health and more resilient communities, more affordable and secure clean energy, accessible to all, to name just a few.

This report – along with our recent reports on Nationally Determined Contributions and National Adaptation Plans – all point in the same direction: the Paris Agreement is working, driving climate actions across economies and societies.

But the pace of change does not yet meet the urgency of this moment, as climate disasters hit every nation harder each year, with colossal human and economic costs.

So I ask you to see this report as both a marker of progress and a call to greater and faster action, at COP30 and every year thereafter.
