By providing clear and robust data and information on climate action, transparency also serves to build trust, credibility and accountability among all those involved.
To strengthen the global response to climate change, countries adopted the Paris Agreement in 2015. As part of this effort, they created a system to track progress, known as the Enhanced Transparency Framework (ETF). Under this system, countries are required to submit a report every two years, starting with their first report (BTR1) by 31 December 2024. By October 2025, 109 countries had submitted their reports, including 46 that received support from UNEP.
UNEP supports countries in adopting the Enhanced Transparency Framework by providing technical and financial support for reporting and support for high-quality, credible, open climate and environmental data, information, statistics, as well as scientific assessments and expertise. UNEP also focuses on building and developing national capacity for climate information services and impact-based multi-hazard early warning systems in developing countries, particularly in LDCs and SIDS.
