However, the IMO rule already stipulates that ships can use any "fitting, material, appliance or apparatus or other procedures, alternative fuel oils, or compliance methods" so long as they are at least as effective in reducing emissions. In a letter sent to the IMO earlier this year, EPA said that the alternatives proposed by the cruise lines to date do not meet this requirement.
"The IMO's regulation is very clear it has to be at least as effective in terms of emissions reductions," said Marcie Keever, director of the oceans and vessels project at Friends of the Earth. "The proposals that we've seen from the cruise industry have not been equivalent and not as effective as what's allowed by the emission control requirements.
"We feel the industry has had ample time to prepare," she added. "And there are real equivalency measures the industry can take advantage of."
