IMO MEPC 84 — Revisiting the net-zero framework
DNV reports that MEPC 84 continued discussions on the IMO Net-Zero Framework after the October 2025 extraordinary session was adjourned, with divergent positions still unresolved.

Shipowners Club — Data-driven safety and behavioural intelligence
The Shipowners Club article, developed with Nautical Nexus, discusses how artificial intelligence, natural language processing and onboard behavioural data may supplement audits by detecting fatigue, communication breakdowns, procedural drift and equipment interaction risks in real time.
