UN Climate Change News, 10 August 2026 – Colombia has become the first country to submit its second Biennial Transparency Report (BTR2) under the Paris Agreement’s Enhanced Transparency Framework (ETF), marking an important milestone for the transparency system that underpins global climate action.
Submitted well ahead of the 31 December 2026 deadline, Colombia’s BTR2 was filed on 8 August 2026, alongside its fourth National Communication under the UN Framework Convention on Climate Change. It covers the country’s national inventory of greenhouse gas emissions and removals; progress towards its nationally determined contribution (NDC); mitigation policies and measures; climate impacts and adaptation; support needed and received in the areas of finance, technology transfer and capacity-building; Action for Climate Empowerment; and research and systematic observation.
The submission demonstrates that the ETF is working as intended. Countries are steadily strengthening their reporting capacity and national transparency arrangements. The data collected can then be used to sharpen climate policy, direct support where it is most needed, and accelerate the implementation of mitigation and adaptation actions.
Colombia’s BTR2 builds on its first report while incorporating methodological improvements and stronger approaches to tracking progress. It shows how successive reporting cycles can improve both national systems and the information available to decision-makers.
Transparency is a cornerstone of the Paris Agreement. It builds trust among countries, helps show whether commitments are being delivered, and provides the evidence needed to strengthen ambition and accelerate action. Each report makes the collective picture clearer and helps countries make better informed decisions. This is especially important as Parties prepare to launch the second global stocktake at COP31.
UN Climate Change encourages all Parties to sustain this momentum. Parties at all stages of the reporting process are encouraged to continue advancing their BTR preparations and submissions, helping to sustain momentum and support the biennial reporting cycle. Parties that have already submitted a first BTR are encouraged to submit their second by the end of 2026.
UN Climate Change remains ready to support Parties in implementing the ETF. This includes providing technical assistance and capacity-building for developing countries that require additional support. More information is available here.
