no, it is absolutely the marginal numbers that matter.
All else equal, starting anywhere but the place with the most pollution per $ produced is a sub-optimal place to start.
In a world that has climate change under control, there's for sure going to be a reduction in pollution produced by global shipping, but in the world we live in there's much better places to start than by limiting global shipping.
