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

Fuel producers and jetmakers are keen to display novel kinds of aviation fuel deemed less damaging to the climate, from utilized cooking oil to the clearly less glamorous meat waste.

Business jet operators, like airline companies, have actually acquiesced ecological pressure on aviation and committed to cutting in half carbon emissions by 2050 compared to 2005.

Their hope is that adopting renewable fuel to curb emissions could make service jets more attractive to environmentally conscious buyers - particularly corporations facing concerns over sustainability from shareholders or green project groups.

The availability of less polluting private jets could likewise spare the rich and famous the unfavorable promotion experienced by Britain's Prince Harry and his partner Meghan over a current personal jet trip to southern France.

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

The most recent waste-based fuels consist of "fats, grease and oils that are by-products of the food industry," said Bryan Sherbacow, chief industrial officer of Boston-based biofuel manufacturer World Energy, which produces fuel from meat waste used 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 anticipated to be pumped at the program.

FLIGHT SHAMING

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

Prince Harry has actually defended his occasional usage of private jets to ensure his family's safety, and has stated that on the uncommon occasions he does not fly commercially he offsets his emissions.

But planemakers state occurrences such as the furore over his itinerary have actually included fresh obstacles for a market currently making every effort to validate its contribution to cutting business expenses.

"Incidents of flight shaming including using private jets are unfortunate when you consider that our industry has delivered fuel efficiency improvements of 40% over the past 40 years," said Bombardier Aviation President David Coleal.

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

But even an image transformation - with jets sporting stickers like "this aircraft flies on eco-friendly fuels" and organisers including alternative fuel pumps for visiting airplanes - is unlikely to please all critics at the Oct 22-24 luxury jet event.

Environmentalists and some analysts stay hesitant that biojetfuels, normally blended 50-50 with kerosene, will make a significant influence on public understandings about luxury travel.

"No amount of Jatropha or Brazil-nut fuel can make organization jets look eco-friendly," stated air travel expert Richard Aboulafia.

Demand from business jet operators for eco-friendly fuels now far exceeds supply and their interest could 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 specialists are also seeing more interest from clients who wish to buy carbon credits to offset emissions from their flights.

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

"At the end of the day, I think that rate, cost per hour, range, speed and efficiency, that's still the (sales) chauffeur. But I believe individuals are becoming more knowledgeable about the sustainability of operations and how it impacts the world."
