LAS VEGAS, Oct 22 (Reuters) - At the world's greatest market show in Las Vegas high-end jets are luring buyers with their smooth shapes, plush cabins - and progressively, their usage of alternative fuels.

Fuel producers and jetmakers are keen to showcase novel kinds of aviation fuel considered less harmful to the climate, from used cooking oil to the distinctly less attractive meat waste.

Business jet operators, like airlines, have acquiesced ecological pressure on air travel and devoted to cutting in half carbon emissions by 2050 compared with 2005.

Their hope is that adopting renewable fuel to curb emissions could make organization jets more attractive to ecologically mindful purchasers - specifically corporations facing concerns over sustainability from shareholders or green campaign groups.

The schedule of less contaminating personal jets could likewise spare the abundant and well-known the negative publicity experienced by Britain's Prince Harry and his better half Meghan over a recent personal jet trip to southern France.

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

The most current waste-based fuels consist of "fats, grease and oils that are by-products of the food industry," stated Bryan Sherbacow, primary industrial officer of Boston-based biofuel producer World Energy, which produces fuel from meat waste utilized by Gulfstream.

"All of our item is inedible."

A few of the other 79 aircraft on display screen are expected to be powered by 150,000 gallons of other sustainable fuel mixes anticipated to be pumped at the show.

FLIGHT SHAMING

Private jets represent less than 0.1% of overall yearly carbon emissions worldwide, however can discharge, usually, as much as 20 times more carbon emissions per passenger mile than jetliners, according to the London-based personal charter firm Victor.

Prince Harry has actually defended his periodic use of personal jets to ensure his family's security, and has actually said that on the unusual celebrations he does not fly commercially he offsets his emissions.

But planemakers state occurrences such as the furore over his itinerary have actually added fresh obstacles for a market already aiming to validate its contribution to cutting corporate costs.

"Incidents of flight shaming involving the use of private jets are unfortunate when you think about that our market has delivered fuel performance enhancements of 40% over the past 40 years," said Bombardier Aviation David Coleal.

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

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

Environmentalists and some experts remain skeptical that biojetfuels, typically mixed 50-50 with kerosene, will make a considerable effect on public perceptions about luxury travel.

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

Demand from organization jet operators for renewable fuels now far goes beyond supply and their interest might drive future production, Sherbacow said.

World Energy, which produces 40 million gallons of biofuel at its California plant, could broaden production up to 150 million gallons by 2022.

Corporate charter companies and experts are likewise seeing more interest from clients who wish to buy carbon credits to balance out emissions from their flights.

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

"At the end of the day, I believe that price, cost per hour, variety, speed and performance, that's still the (sales) chauffeur. But I believe individuals are becoming more aware of the sustainability of operations and how it impacts the planet." (Reporting By Allison Lampert, Editing by Tim Hepher and Alexandra Hudson)
