Green ammonia could decarbonize 60% of global shipping when offered at just 10 regional fuel ports

2. So, a 60% reduction of 3% of global emissions?

That would shave 1.8% off global emissions by 2050, which is pretty decent, but not spectacular in and of itself.

But this stood out at me:

The study shows that the greatest investment need is in Australia, to supply the Asian markets, with large production clusters also predicted in Chile (to supply South America), California (to supply Western U.S.A.), North-West Africa (to meet European demand), and the southern Arabian Peninsula (to meet local demand and parts of south Asia).

One of Australia's largest exports to Asia is coal. Northwest Africa moves Nigerian oil. Arabian Peninsula exports are oil tankers. Are we going to build green cargo ships to fight climate change, but use them to move coal and oil?
