Countries are steadily strengthening their reporting capacity and national transparency arrangements. This is especially important as Parties prepare to launch the second global stocktake at COP31. Parties that have already submitted a first BTR are encouraged to submit their second by the end of 2026. UN Climate Change says it remains ready to support Parties in implementing the ETF.
