When tankers skip Hormuz or hug longer African routings, carbon intensity per barrel delivered rises even if absolute crude demand falls. Climate-aware shipping analysts flagged that dynamic again Friday while oil markets digested sanctions headlines atop war logistics.

AIS tracks showing sparse Hormuz transits imply massive rerouting. Marine insurers’ war-risk surcharges further discourage efficient short paths. The result is a messy climate ledger: demand destruction versus detour emissions.

IMO efficiency rules were not written for wartime chokepoint collapse, leaving a governance gap.

Analysts agree detours raise per-barrel voyage emissions; magnitudes depend on route assumptions. Officials and independent outlets continue updating confirmed details as they become available.
