UN Climate Change News, 6 November 2025 - UN Climate Change last week released the 2025 Synthesis Report of Biennial Transparency Reports (BTRs), offering the most comprehensive picture yet of how countries are turning the Paris Agreement into action. Drawing on submissions from 109 countries as of 15 April 2025, the report shows that climate implementation is advancing across mitigation, adaptation, and support.
UN Climate Change Executive Secretary Simon Stiell welcomed the findings as "a clear sign that Parties are very actively starting to implement the Paris Agreement, with practical real-world actions, across economies and societies."
Across every region, countries are putting the Paris Agreement into practice - through stronger policies, new institutions, and whole-of-society approaches that are driving change in the real economy. From renewable energy expansion and reforestation to electric vehicles, energy efficiency, and emissions trading schemes, the evidence shows that the transition is well under way - but it must be urgently scaled up.
"This report provides valuable insights ahead of COP30 in Belém, which will be the world's moment to respond, and pick up the pace, in this new era of implementation," added Stiell.
According to the report, all Parties that submitted their first BTRs have taken tangible steps to meet their climate commitments - from establishing new legal and institutional systems to track emissions and adapt to climate impacts, to mobilizing finance for resilience and clean energy transitions. These measures are strengthening countries' capacity to design and implement more ambitious climate strategies.
While the report highlights encouraging progress, it also underscores that the current pace of change remains insufficient to meet global temperature goals. Persistent gaps in financing, capacity building, and technology transfer - particularly for developing countries facing disproportionate challenges - must be urgently addressed through greater international cooperation.
The synthesis report identifies key enablers for faster progress: more and higher-quality finance where it's needed most; strong data and transparency systems; and inclusive, just transitions that ensure far more people share in the human and economic benefits of climate action.
The findings mark a major milestone for the Enhanced Transparency Framework (ETF) of the Paris Agreement, which requires countries to report every two years on progress toward their national climate plans (NDCs).
As the world prepares for COP30, the report's findings serve as both a marker of progress and a call to greater and faster action. The Paris Agreement is working - driving climate action across economies and societies - but nations must now accelerate and scale up efforts to transform today's progress into collective, transformative action.
