United Airlines: Mest miljøvenlige kommercielle flyvning

Skrevet af Dmytro Makarov

United Airlines made history today – World Environment Day – with the departure of the Flight for the Planet, the most eco-friendly commercial flight of its kind in the history of aviation.

On the Flight for the Planet, United became the first known airline to demonstrate all of the following key actions on a single commercial flight: utilization of sustainable aviation biofuel; zero cabin waste efforts; carbon offsetting; and operational efficiencies.

United bruger Flight for the Planet til at evaluere nøglemålinger for at flyve så bæredygtigt som muligt ved hjælp af flyselskabets nuværende teknologi, ressourcer og brændstofbesparende procedurer. Flyvningen gik fra gate B12 ved Uniteds hjembyhub i Chicago O'Hare for sin "øko-hub" i Los Angeles, hvor bæredygtig luftfart har været med til at drive alle flyselskabets flyvninger fra det sydlige Californien-hub siden 2016.

”Den historiske flyvning for planeten viser Uniteds filosofi om at arbejde sammen for at finde nye og innovative måder at føre os ind i en mere bæredygtig fremtid,” sagde Scott Kirby, Uniteds præsident. "Som et flyselskab ser vi vores miljø fra et unikt perspektiv hver dag, og vi ved, at vi skal gøre vores del for at beskytte vores planet og vores himmel."

Flyvningen til planeten illustrerer yderligere Uniteds forpligtelse til dets dristige løfte om at reducere dets CO50-fodaftryk med 2050% inden XNUMX.

Sustainable Aviation Biofuel

United is powering the Flight for the Planet using a 30/70 blend of low-carbon, sustainable aviation fuel provided by Boston-based World Energy, and traditional jet fuel. The biofuel alone achieves a greater than 60% reduction in greenhouse gas emissions on a lifecycle basis compared to traditional jet fuel, and using biofuel is one of the most effective ways an airline can reduce its impact on the environment.

United recently renewed its contract with World Energy, agreeing to purchase up to 10 million gallons of cost-competitive, sustainable aviation biofuel over the next two years. United was the first airline globally to use sustainable aviation biofuel on a continuous basis and the only airline in the United States to currently do so.

Zero Cabin Waste and Industry-First, Recyclable-Paper Cup

In the Economy cabin, United is swapping traditional snack options with a complimentary plated service featuring fully recyclable or compostable serviceware, including a test of an industry-first, recyclable-paper, hot beverage cup.

In the premium cabin, United is continuing to use reusable service ware and swap plastic lids for beeswax food wrappers. The airline is also removing the paper wrapping from silverware roll-ups. United has already eliminated non-recyclable stirring sticks and cocktail picks on aircraft systemwide and replaced them with an environmentally-friendly product made of 100% bamboo.

Kulstofudregning

United is offsetting the remainder of the flight’s emissions via the airline’s new carbon offset provider, Conservation International. Conservation International now partners with United on the airline’s consumer carbon offset program – Eco-Skies CarbonChoice – and together the two allies will focus on CI’s mission to promote nature-based solutions to climate change.

Operational Efficiencies

United has made significant investments in a modern, fuel-efficient fleet while implementing operational and procedural changes to drive fuel conservation. The Flight for the Planet is demonstrating single-engine taxiing, Air Traffic Control prioritization and a continuous descent approach into Los Angeles, which saves fuel while also reducing noise impact to the city. United is operating the flight using its Eco-Skies livery Boeing 737-900ER, which on average carries passengers 77 miles on a single gallon of fuel.

Additionally, 40% of United’s eligible ground service equipment (GSE) is electric-powered, with more than 70% of the airline’s ground operation at its Los Angeles eco-hub utilizing electric GSE equipment. United is the first airline to use new ITW 7400 electric ground power units that drastically reduce workplace noise pollution and cut carbon emissions by 90%. United is also using electric-powered ground equipment to service the Flight for the Planet at the departure and arrival gates.

Uniteds engagement i miljøet

United’s Flight for the Planet represents yet another innovative initiative the airline has undertaken to reduce its overall footprint and further ensure its reputation as the world’s most environmentally conscious airlines. Several of United’s most significant environmental achievements include:

Becoming the first airline globally to use sustainable aviation biofuel on a continuous basis, marking a significant milestone in the industry by moving beyond test programs and demonstrations to the everyday use of low-carbon fuel in ongoing operations.
Investing more than $30 million in California-based sustainable aviation fuels producer Fulcrum BioEnergy, which remains the single largest investment by any airline globally in sustainable fuels. United’s agreement to purchase nearly 1 billion gallons from Fulcrum BioEnergy is the largest offtake agreement for biofuel in the airline industry.
Becoming the first airline to fly with Boeing’s Split Scimitar winglets, which reduce fuel consumption by an additional 2 percent versus standard winglets; United is the largest Scimitar winglet operator today, with nearly 400 aircraft equipped with these winglets.
Becoming the first U.S. airline to repurpose items from the carrier’s international premium cabin amenity kits and partnering with Clean the World to donate hygiene products to those in critical need.
Partnering with Audubon International to protect raptors – including hawks, owls and kestrels – in and around United’s hubs and resettle the birds of prey at habitats where the species are more likely to thrive.
