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

Fuel producers and jetmakers are eager to showcase novel forms of air travel fuel deemed less harmful to the climate, from used cooking oil to the distinctly less attractive meat waste.

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

Their hope is that embracing eco-friendly fuel to suppress emissions might make service jets more attractive to buyers - specifically corporations dealing with questions over sustainability from shareholders or green project groups.

The schedule of less contaminating private jets might likewise spare the rich and famous the negative publicity experienced by Britain's Prince Harry and his better half Meghan over a current personal jet trip to southern France.

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

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

"All of our item is inedible."

Some of the other 79 aircraft on display screen are anticipated to be powered by 150,000 gallons of other renewable fuel blends anticipated to be pumped at the program.

FLIGHT SHAMING

Private jets represent less than 0.1% of overall yearly carbon emissions globally, but can give off, usually, as much as 20 times more carbon emissions per guest mile than jetliners, according to the London-based private charter company Victor.

Prince Harry has protected his occasional use of private jets to guarantee his household's safety, and has actually said that on the rare celebrations he does not fly commercially he offsets his emissions.

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

"Incidents of flight shaming including the use of private jets are unfortunate when you think about that our market has provided fuel effectiveness improvements of 40% over the past 40 years," stated Bombardier Aviation President David Coleal.

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

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

Environmentalists and some experts stay doubtful that biojetfuels, typically mixed 50-50 with kerosene, will make a substantial effect on public understandings about luxury travel.

"No quantity of Jatropha or Brazil-nut fuel can make service jets look eco-friendly," said aviation analyst Richard Aboulafia.

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

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

Corporate charter business and consultants are also seeing more interest from customers who wish to buy carbon credits to balance out emissions from their flights.

Brian Proctor, CEO of Mente Group, a U.S. consultancy, said emissions played a role in a business jet utilization research study his company recently completed for a Fortune 500 company.

"At the end of the day, I believe that price, expense per hour, range, speed and efficiency, that's still the (sales) motorist. But I think people are becoming more knowledgeable about the sustainability of operations and how it affects the world." (Reporting By Allison Lampert, Editing by Tim Hepher and Alexandra Hudson)
