Through MARPOL annex VI the IMO focuses on reducing the carbon emissions “globally”
The idea behind not including the annex vi in PWC is that IMO decides not only on the basis of environmental considerations but also the commercial viability
The other reason is the density of traffic in polar waters which is very less compared to the other parts of the planet which impacts the global warming issue predominantly.
The other reason is the availability of optimum resources in polar water reasons including the current designs of engines and machinery. I am sure member states wont let it happen soon
Having said that
The decisions at IMO are also subjected to widely conducted scientific research.
The issue of ‘black smoke’ in polar waters is a bigger challenge than anything else currently
