Carnival Corporation & plc, the world's largest cruise firm, has released the results of its multi-year Fleet Fuel Conservation Program that by the end of 2014 will have saved more than one billion gallons of fuel and reduced fleet carbon emissions by 12 billion kilograms over a seven-year period.

By the end of 2014, Carnival's Fleet Fuel Conservation Program is expected to have improved the fleet’s overall fuel efficiency by 24 percent compared to 2007, while saving approximately $2.5 billion in fuel costs, the company's single biggest expense.

Carnival's Fleet Fuel Conservation Program combines energy-saving programs onboard current ships with new energy-efficient ship designs to reduce energy consumption and boost fuel efficiency across its fleet of over 100 ships. The program has become a cornerstone of the corporation’s strategy to collaborate across its nine brands and leverage its scale, while supporting sustainability initiatives designed to reduce environmental impact from maritime operations.

Since cruise ships generate their own electricity from fuel, Carnival set out to uncover every feasible way to reduce onboard energy usage and launched several key conservation initiatives since 2007 that have driven the Fleet Fuel Conservation Program. These efforts include:

- Propulsion: Improving how the ship moves through the water by optimizing ship speeds and cruise distances to design more fuel-efficient itineraries, significantly reducing energy and fuel consumption.

- Hull coatings: Using new hull coatings and cleaning technologies to minimize the growth of marine organisms that create drag on the hull, which reduces the amount of fuel needed to move the ship through water.

- Air conditioning: Installing new, energy-efficient A/C systems to help reduce the energy used to cool the ships, which is the second largest consumer of onboard energy after propulsion.

- Lighting: Replacing traditional lighting with more efficient LED bulbs is an ongoing opportunity to save energy, as the company continues the process of replacing four million lights across the fleet.

- Water production: While producing 73 percent of water used onboard its ships, Carnival is reducing the rate of onboard water usage and finding more efficient ways to produce water, including better use of engine heat to convert sea water to fresh water and installation of reverse osmosis systems.

- Education & Training: Increasing onboard energy use awareness among officers, crew and guests.

- Other initiatives: The company is pursuing additional energy-saving ideas for engine room cooling equipment, audio and entertainment systems, galley/cooking appliances and laundry services, and expanding the 20 percent of ships equipped for “cold ironing” as more ports offer the ability to connect to shore electrical power. Carnival also continues to develop its ability to use alternative fuels.

New ship builds also drive significant improvements in fleet fuel efficiency through energy-saving innovations that are designed directly into the new vessels. By adding over 30 new ships to its fleet since 2007, Carnival has aimed to capitalize on the latest advances in energy efficiency, including building larger ships with highly efficient propulsion systems that incorporate new computer-modeled hull designs and the latest in fuel-efficient propeller and engine combinations.

"We have made great strides in working together to reduce energy and fuel consumption across our fleet, which is a top priority for us as a company," said Arnold Donald, CEO of Carnival Corporation. "We are very proud of our conservation efforts, but we also realize that doing our part to reduce carbon emissions and help protect the environment is a job that is never complete. We’re committed to building on the momentum of our sustainability initiatives because it is the right thing to do for the environment and our fellow citizens, the passengers and crew on our ships, the communities we visit, and also for our business."

Expanding environmental efforts across nine cruise brands

Carnival says its Fleet Fuel Conservation Program is part of its deep-rooted commitment to protect the natural environments in which it operates, while also reducing emissions from its ships and improving air quality.

The company says that fuel conservation is its top environmental priority and expects to increase fuel efficiency by five percent in 2014 alone. Driven largely by its energy and fuel conservation efforts, Carnival says it is now in a position to exceed its goal of a 20 percent reduction in carbon emissions by 2015.

Carnival is investing as much as $400 million to design, build and install exhaust gas cleaning technology, called ECO-EGC, to more than 70 percent of its fleet. The system uses filters and seawater to remove pollutants from exhaust gases, significantly advancing cleaner air quality for ocean-going vessels.

In addition to these efforts, the company continues to focus on additional environmental initiatives, including using effective waste management, employing on-board environmental officers on every ship and partnering with environmental organizations such as The Nature Conservancy to support protection of the global marine environment.

These efforts by Carnival, paired with efforts from other parties in the maritime industry, are said to have had an impact on environmental preservation. According to the Secretary General of the International Chamber of Shipping, there has been a 20 percent reduction in greenhouse gas emissions for the entire global maritime transportation industry from 2007 to 2012. Carnival is also a member of the Sustainable Shipping Initiative, whose main goal is to promote sustainability within the global maritime industry.

The three Cs

The Fleet Fuel Conservation Program has served as a model for Carnival's strategy to work closely together across its nine brands through collaboration, cooperation and communication – known internally as 'the Three Cs' – to improve guest experiences, strengthen brands, boost operational efficiency, reduce expenses and generate new sources of revenue.

The company’s extensive working-together program across its brands is designed over the longer term to generate significant cost-savings and revenue while improving quality.

"This effort embodies and helps actualize the sustainability values embedded in Carnival Corporation’s health, environment, safety and security policy," the company said.
