Interesting.
See

Then there is this article on the "crazy idea" of lengthening the ship by adding a prebuilt lng component in the middle and the pros and cons:

And a slide presentation about converting to lng and the "crazy idea" with some more details and pictures that help explain the concept.
Also
Some googling turned up the
Friends of the Earth website who does an annual "report card" on cruise ships.
According to them, for Disney:
"
However, all of Disney’s ships burn fuel with a 0.1% sulfur content worldwide which is lower than what is required internationally, earning the company an A- in the air pollution reduction category. The Disney Wonder traveled to Alaska annually from 2011 to 2019 and received no violations of state water pollution standards. In addition, Disney does not utilize scrubbers on its fleet, giving Disney an A for water quality compliance." [

This organization goes even further than stand.earth though,
https://foe.org/blog/what-would-a-clean-cruising-industry-look-like/ :
Here are the top 5 things the cruise industry can do now to get to clean cruising:
1) Climate Change: Stop contributing to climate change.
(1.1) Publicly commit to achieving zero emissions across your entire global fleet by 2050 at the latest, with a 40% reduction in the first decade, followed by a minimum of 5% year-over-year reductions from 2030-2050. (1.2) Immediately progress towards your absolute greenhouse gas reduction targets by implementing a slow-steaming protocol across your entire fleet. (1.3) Halt liquified natural gas (LNG) investments, and redirect those resources towards zero emissions strategies, including research, development, and testing of sustainable fuels such as green hydrogen or ammonia. (1.4) In order to reduce unhealthy and climate-harming black carbon emissions, publicly commit to immediately cease the use and carriage of high sulfur fuel oil (HSFO) globally and the use of both HSFO and very low sulfur fuel oil (VLSFO) in the Arctic. Switch to distillate/marine gas oil (MGO) and install efficient particulate filter systems or switch to other cleaner non-fossil fuels, technologies, or propulsion systems.
So they are against LNG *and* diesel...
They also encouraged their supporters to "Tell the CDC" to "Extend the No Sail Order for polluting and unsafe cruises!". They have a number of "Cruise Industry Restart Demands" that go well beyond pollution-related concerns at
https://foe.org/blog/cruise-industry-restart-demands/
So stand.earth is not alone in attempting to take advantage of the covid no sail order situation to leverage a broader anti-cruise agenda.
