No new scrubber guidelines

Exhaust gas cleaning systems (EGCS), also known as scrubbers, can be used by ships as an alternative to low-sulphur fuels to achieve emission reductions, and scrubber guidelines were adopted by the International Maritime Organisation’s (IMO) Marine Environment Protection Committee (MEPC) in 2009, but with a caveat that the wash-water discharge criteria should be revised as more data became available on the contents of discharge and its effects on the environment.

Norway had previously pointed out issues to be resolved, regarding demonstration of equivalence for EGCS with emission reductions from using low-sulphur fuels, and approval, enforcement and compliance of EGCS.

In February an IMO technical committee agreed – after some discussion – that revision of the 2009 guidelines should be further delayed.
