To provide a detailed analytical readout of the two-week negotiations at the IMO—namely the MEPC Extraordinary Session and ISWG-GHG 20—explaining why the Net Zero Framework (NZF) was not adopted, what political and procedural dynamics shaped that outcome, how Member States took action during the process, and what technical progress was made on the NZF-related guidelines (ZNZ definition, reward mechanisms, the Net Zero Fund, LCA guidelines, GFI registry, etc.)
