Cargo ships looks like a diversion from lobbies. It should be relatively easy to solve (upgrading 50k motors is much easier than redesign transport on land to trains, subway and bus). The trick is to conflate nitrogen oxide emission with air pollution.

When I look at data I find that transport is "20% of CO2 emission" (https://ourworldindata.org/co2-and-other-greenhouse-gas-emis...) but shipping is "2.2% of the global human-made emissions in 2012" (form wikipedia http://www.imo.org/en/OurWork/Environment/PollutionPreventio...)

What does it means ? Well, shipping uses dirty fuel and is very polluting but that's also a scapegoat for individual consumerist culpability.
