Example: what a research answer looks like
What is the current enforcement trend under MARPOL Annex VI?
Enforcement of MARPOL Annex VI has intensified measurably since Q3 2025, with port state control detentions for air emissions violations rising 34% year-on-year according to the Tokyo MOU annual report [1]. The IMO’s Carbon Intensity Indicator framework, which entered into force in January 2026, has created a new category of compliance exposure. Ships rated D or E for three consecutive years now face mandatory corrective action plans [2]. Three enforcement actions in the Tideline IUU tracker in the last 60 days involved Annex VI violations as secondary charges alongside flag state irregularities, suggesting port state authorities are increasingly bundling emissions compliance into broader inspections [3].
