英联邦The Commonwealth：2026年英联邦国家首届两年期透明度报告审查（英文版）

Biennial Transparency Reports (BTRs) offer unique insights into the diverse capacities, achievements and challenges of Commonwealth member countries in meeting their transparency obligations under the Paris Agreement. By reviewing them alongside UNFCCC data and country-level survey and interview feedback, this report identifies best practices and evidence of progress, and provides recommendations for how the 'transparency gap' can be closed ahead of the next BTR cycle.
