"This report is inaccurate and misleading," a Carnival representative said. "Our fleet includes Advanced Air Quality Systems on more than 70 more of our ships and we have shore power capability on just under 50% of our fleet. Plus we have the latest advancements in our treatment plants installed on board (and each of these technologies are included on our new ships — and we have 18 new ships on order). We also are the first cruise company to install LNG to power our ships."
