How are you dividing up other sources such that shipping would be the 6th heaviest source? At roughly 2% of total global emissions, it seems like you'd have to lump other sources together in a strange way to come up with that ranking. For example, looking at: https://www.c2es.org/content/international-emissions/ https://www.c2es.org/content/international-emissions/ Taking shipping as a separate thing, it would rank 7th in the chart of total emissions and 6th in the chart of energy-related emissions, but only because those charts only contain 6 and 5 entries respectively.
