LAS VEGAS, Oct 22 (Reuters) - At the world's biggest industry show in Las Vegas luxury jets are enticing buyers with their streamlined silhouettes, plush cabins - and progressively, their use of alternative fuels.

Fuel manufacturers and jetmakers are eager to display novel forms of aviation fuel deemed less damaging to the environment, from utilized cooking oil to the distinctly less attractive meat waste.

Business jet operators, like airlines, have actually bowed to environmental pressure on aviation and committed to halving carbon emissions by 2050 compared with 2005.

Their hope is that adopting eco-friendly fuel to suppress emissions could make business jets more appealing to ecologically mindful buyers - particularly corporations dealing with questions over sustainability from shareholders or green campaign groups.

The accessibility of less polluting personal jets could likewise spare the rich and well-known the unfavorable promotion experienced by Britain's Prince Harry and his better half Meghan over a current private jet trip to southern France.

Five Gulfstream jets on display screen in Las Vegas are utilizing California-produced fuel from inedible beef tallow.

The most recent waste-based fuels consist of "fats, grease and oils that are byproducts of the food market," said Bryan Sherbacow, primary business officer of Boston-based biofuel producer World Energy, which produces fuel from meat waste utilized by Gulfstream.

"All of our product is inedible."

Some of the other 79 airplane on display screen are anticipated to be powered by 150,000 gallons of other renewable fuel mixes expected to be pumped at the show.

FLIGHT SHAMING

Private jets account for less than 0.1% of total yearly carbon emissions internationally, however can emit, on average, approximately 20 times more carbon emissions per traveler mile than jetliners, according to the London-based private charter company Victor.

Prince Harry has actually safeguarded his occasional use of private jets to ensure his household's security, and has actually stated that on the rare events he does not fly commercially he offsets his emissions.

But planemakers state occurrences such as the furore over his schedule have actually included fresh difficulties for a market currently aiming to validate its contribution to cutting corporate costs.

"Incidents of flight shaming involving making use of personal jets are unfortunate when you think about that our market has actually provided fuel effectiveness enhancements of 40% over the past 40 years," said Bombardier Aviation President David Coleal.

Bombardier thinks increased sustainable fuel usage will assist the industry make inroads with corporations and wealthy buyers. According to industry data, billionaires only have a 19% organization jet ownership rate.

But even an image makeover - with jets sporting stickers like "this airplane flies on eco-friendly fuels" and organisers including alternative fuel pumps for going to airplanes - is not likely to satisfy all critics at the Oct 22-24 luxury jet event.

Environmentalists and some analysts stay doubtful that biojetfuels, generally 50-50 with kerosene, will make a considerable impact on public understandings about luxury travel.

"No amount of jatropha curcas or Brazil-nut fuel can make organization jets look eco-friendly," stated aviation analyst Richard Aboulafia.

Demand from company jet operators for renewable fuels now far surpasses supply and their interest could drive future production, Sherbacow said.

World Energy, which produces 40 million gallons of biofuel at its California plant, could expand production as much as 150 million gallons by 2022.

Corporate charter business and experts are likewise seeing more interest from customers who desire to buy carbon credits to offset emissions from their flights.

Brian Proctor, CEO of Mente Group, a U.S. consultancy, said emissions contributed in a business jet usage research study his company just recently finished for a Fortune 500 company.

"At the end of the day, I think that price, cost per hour, variety, speed and efficiency, that's still the (sales) driver. But I think individuals are ending up being more mindful of the sustainability of operations and how it affects the world." (Reporting By Allison Lampert, Editing by Tim Hepher and Alexandra Hudson)
