If a there is no marker on a port and there is no information on the use of EGCS in the surrounding national or regional waters, it can be generally assumed that exhaust gas cleaning can be used without restriction. EGCSA recommends, however, that requirements are always confirmed with the appropriate maritime authority.

Green – scrubbers can be used as a method of compliance with fuel sulphur regulations and overboard discharges are permitted, if in compliance with IMO Guidelines (MEPC.259(68) 2015 Guidelines for Exhaust Gas Cleaning Systems)
Amber – scrubbers can be used as a method of compliance with fuel sulphur regulations, but additional regional, national or local compliance criteria may apply
Black – scrubbers can be used as a method of compliance with fuel sulphur regulations but overboard discharges are prohibited (e.g. from open loop scrubbers)
