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 on
32 Ships, Becomes First to Use Innovative 'Scrubber' Solution in Restricted
Spaces 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 support
of the U.S. Environmental Protection Agency (EPA), the U.S. Coast Guard and
Transport Canada to implement a significant advancement in environmental
technology designed to reduce air emissions from cruise ships and large marine
vessels.

As part of today's announcement, Carnival has committed over $180 million for
exhaust gas cleaning technology on 32 ships. These include vessels from
Carnival Cruise Lines, Holland America Line, Princess Cruises and Cunard that
sail regularly within the North American Emission Control Area (ECA).

"This is a significant accomplishment as well as an important milestone for our
company," said Carnival Corporation & plc CEO Arnold Donald. "Working together
with the EPA, U.S. Coast Guard and Transport Canada, we have developed a
breakthrough solution for cleaner air that will set a new course in
environmental protection for years to come."

Carnival has been a partner in the development of this technology and will take
the lead in further refining both design and installation aspects on ships with
a variety of engine configurations between now and mid-2016.

This new generation of so-called "scrubber technology" combines the removal of
sulfur with the substantial reduction of particulate matter and black carbon.
Once the exhaust gas cleaning technology is installed and fully operational on
the various Carnival subsidiary ships, they will exceed ECA standards. The
International Maritime Organization's MARPOL Annex VI places a cap on sulfur
within ECAs at 1.0%, which took effect in North America in 2012. In 2015, the
limit will be 0.1%.

Carnival's design combines two established technologies, which have been
successfully used in power plants, factories and vehicles to clean - or scrub -
the exhaust from high-sulfur fuel. For the first time this combination is being
developed to accommodate restricted spaces on existing ships.

In addition to exceeding stricter air emission standards - a significant public
health advancement - Carnival's technology will help the company mitigate
escalating fuel costs. The agreement in principle from the EPA and Coast Guard
would enable an exemption for Carnival to use the fuel source that makes the
most sense from an environmental and economic perspective. The agreement in
principle is a requirement for the flag states of each Carnival subsidiary to
grant permission for implementation.

The implementation also produces an immediate significant public health
benefit, as all of the ships that will have the scrubber technology installed
will use either low-sulfur marine gas oil or shore power when in ports in the
United States and Canada. Ships that use shore power turn off diesel engines
and connect to local electric utility power.

As a next step, Carnival will be requesting permits from flag states to allow
for the trial of the exhaust gas cleaning technology to proceed.

Looking ahead, Carnival plans to explore the possibility of expanding the
installation of its scrubber technology beyond the initial 32 ships.
