Hawaiian Earns Carbon Credits Through Engine-Washing
EcoPower reduces fuel burn by using atomized water to wash engines in a closed-loop system that both filters and reuses water. The system helped the carrier reduce CO2 emissions by nearly 22,000 metric tonsâ€”the equivalent of taking 700 cars off the road annuallyâ€”since embarking on the program in 2005. The project also saved more than 2.5 million gallons of fuel and about 26,000 gallons of water.
Hawaiianâ€™s previous environmental initiatives include teaming up with Rolls-Royce to build a fleet of fuel-efficient planes, according to KHNL.com. The airline adopted performance-enhancing wing tips, as well as lighter passenger seats and service carts on its current wide-body fleet. The carrier has also implemented measures to recycle waste materials, and use renewable and biodegradable resources in onboard meal packaging and utensils.
More carriers are adopting such sustainability-oriented practices as the airline industry moves toward cleaner-burning alternatives to fossil fuels for jet engines. For example, Southwest Airlines reportedly debuted a redesigned cabin with seats that achieve weight savings of nearly six pounds eachâ€”or 635 pounds per aircraft.
