The COP31 Host Country Agreement between the Government of Türkiye and the UNFCCC has completed ratification and entered into force, providing the legal basis for the November 9-20 climate conference in Antalya. It consolidates gender, Indigenous Peoples and local communities, and persons with disabilities into a human-rights and inclusion framework. Accommodation for delegates funded through the Trust Fund for Participation is capped at 50% of the daily subsistence allowance, while the host must engage the hospitality sector early and explain consumer rights. The agreement also requires project-management best practices, risk, timeline and milestone tracking, and a post-conference report to the Bureau. It cannot replace emissions negotiations, but it directly affects whether resource-constrained countries can participate and whether the conference runs more transparently and efficiently.
