Carnival Receives Support For Air Emissions Technology

Carnival Receives Support From EPA, U.S. Coast Guard and Transport Canada to Implement Breakthrough Technology to Reduce Air Emissions Carnival Commits Over $180 Million to Install Exhaust Gas Cleaning Systems on32 Ships, Becomes First to Use Innovative 'Scrubber' Solution in RestrictedSpaces on Existing Ships MIAMI, Sept. 5, 2013 -- Carnival Corporation & plc (NYSE/LSE: CCL; NYSE: CUK),the world's largest cruise company, today announced it has received the supportof the U.S. Environmental Protection Agency (EPA), the U.S. Coast Guard andTransport Canada to implement a significant advancement in environmentaltechnology designed to reduce air emissions from cruise ships and large marinevessels. As part of today's announcement, Carnival has committed over $180 million forexhaust gas cleaning technology on 32 ships. These include vessels fromCarnival Cruise Lines, Holland America Line, Princess Cruises and Cunard thatsail regularly within the North American Emission Control Area (ECA). "This is a significant accomplishment as well as an important milestone for ourcompany," said Carnival Corporation & plc CEO Arnold Donald. "Working togetherwith the EPA, U.S. Coast Guard and Transport Canada, we have developed abreakthrough solution for cleaner air that will set a new course inenvironmental protection for years to come." Carnival has been a partner in the development of this technology and will takethe lead in further refining both design and installation aspects on ships witha variety of engine configurations between now and mid-2016. This new generation of so-called "scrubber technology" combines the removal ofsulfur with the substantial reduction of particulate matter and black carbon.Once the exhaust gas cleaning technology is installed and fully operational onthe various Carnival subsidiary ships, they will exceed ECA standards. TheInternational Maritime Organization's MARPOL Annex VI places a cap on sulfurwithin ECAs at 1.0%, which took effect in North America in 2012. In 2015, thelimit will be 0.1%. Carnival's design combines two established technologies, which have beensuccessfully used in power plants, factories and vehicles to clean - or scrub -the exhaust from high-sulfur fuel. For the first time this combination is beingdeveloped to accommodate restricted spaces on existing ships. In addition to exceeding stricter air emission standards - a significant publichealth advancement - Carnival's technology will help the company mitigateescalating fuel costs. The agreement in principle from the EPA and Coast Guardwould enable an exemption for Carnival to use the fuel source that makes themost sense from an environmental and economic perspective. The agreement inprinciple is a requirement for the flag states of each Carnival subsidiary togrant permission for implementation. The implementation also produces an immediate significant public healthbenefit, as all of the ships that will have the scrubber technology installedwill use either low-sulfur marine gas oil or shore power when in ports in theUnited States and Canada. Ships that use shore power turn off diesel enginesand connect to local electric utility power. As a next step, Carnival will be requesting permits from flag states to allowfor the trial of the exhaust gas cleaning technology to proceed. Looking ahead, Carnival plans to explore the possibility of expanding theinstallation of its scrubber technology beyond the initial 32 ships.
