Carnival Corp. has been named the Best Marine Solutions Company in this year's Clean Tech Awards by The New Economy, a quarterly publication.
The publication said the award winners demonstrated a commitment to producing clean technology to improve the environment in 2013.
Carnival is developing ground-breaking exhaust gas cleaning technology, known as "scrubbers," on a number of ships to reduce the amount of air emissions from using high-sulfur fuel.
The scrubbers, which will be on 17 Carnival Cruise Lines ships, nine Holland America Line ships, seven Princess ships and Cunard's Queen Mary 2 by 2016, will exceed new regulations.
AIDA Cruises has also announced a 100 million euro investment to protect the environment, including installing the scrubber technology.
Other initiatives include Carnival's goal to reduce greenhouse gas emissions by 20 percent in 2015 from its baseline 2005 level.
From 2005 to 2012, Carnival has reduced its emission rate by 16.7 percent, including a 3 percent decrease between 2011 and 2012. Carnival has installed water treatment plants on nearly half of its fleet, and plans to install advanced versions of the treatment plants on new ship builds and will continually upgrade existing ones.
It is Carnival's corporate policy to never discharge untreated sewage, despite maritime law allowing it in specific instances.
