From Friends of the Earth’s homesite:

Millions of Americans take cruise vacations every year. Yet, most travelers don’t realize that taking a cruise is more harmful to the environment and human health than many other forms of travel.

The 2014 Cruise Ship Report Card lets vacationers decide which cruise to take based on a cruise ship or cruise line’s environmental and human health impacts.

What can you do about it? You can choose a greener cruise!

All cruise lines are not the same. With our report card, you can choose a greener cruise! With new ships that can carry more than 8,000 passengers and crew, these floating cities pollute the air we breathe and the water we use and enjoy.

Friends of the Earth’s Cruise Ship Report Card compares the environmental footprint of 16 major cruise lines and 167 cruise ships. View a PDF of the report card.

Friends of the Earth’s just-released 2014 Cruise Ship Report Card grades 16 cruise lines and 167 ships on their environmental practices, and once again Carnival Cruise Lines gets a failing grade for its treatment of the ocean.

You can easely write a message to them trough FOEs form on this site.

Clean up your act Carnival!
