The proposals expand upon NMA's June consultation on emissions and discharges within the fjords. A ban on vessels with hybrid , open - loop or closed - loop scrubbers , or which burn water with more than 0.1 % sulphur , in the West Norwegian Sea is under consideration by the Norwegian Maritime Administration ( NMA ) . The waters have UNESCO world heritage status , and as such , the proposed measures build on a consultation held by the authorities in June about emissions and discharges in the region which would see stricter controls on nitrogen oxide emissions , prohibit ##ing of sewage , and regulation of scrubbers . The latest proposals are part of wider , stricter environmental controls set to come into force on 1 January 2019 .
