The International Chamber of Shipping (ICS) has warned that fuel oil non-availability reports, known as FONARs, cannot be used as a “free pass” to carry non-complaint marine fuel after the global sulphur cap comes into force in 2020.

The warning follows a key IMO meeting in London last week, where it was agreed that ships will be allowed to burn high-sulphur fuel oil after 1 January 2020 if they can prove they had legitimate concerns about the quality and safety of available compliant fuels.
