LAS VEGAS, Oct 22 (Reuters) - At the world's most significant industry show in Las Vegas high-end jets are tempting purchasers with their sleek silhouettes, luxurious cabins - and increasingly, their use of alternative fuels.

Fuel producers and jetmakers are eager to display unique kinds of aviation fuel deemed less damaging to the environment, from used cooking oil to the distinctly less attractive meat waste.

Business jet operators, like airline companies, have bowed to environmental 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 suppress emissions could make organization jets more appealing to environmentally conscious purchasers - particularly corporations dealing with concerns over sustainability from investors or green campaign groups.

The accessibility of less jets might likewise spare the abundant 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 screen 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 byproducts of the food industry," said Bryan Sherbacow, chief commercial officer of Boston-based biofuel manufacturer 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 eco-friendly fuel mixes anticipated to be pumped at the program.

FLIGHT SHAMING

Private jets account for less than 0.1% of total annual carbon emissions worldwide, however can discharge, typically, approximately 20 times more carbon emissions per guest mile than jetliners, according to the London-based personal charter firm Victor.

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

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

"Incidents of flight shaming involving making use of private jets are unfortunate when you consider that our industry has actually provided fuel performance enhancements of 40% over the previous 40 years," said Bombardier Aviation President David Coleal.

Bombardier believes increased sustainable fuel use will assist the industry make inroads with corporations and wealthy buyers. According to market information, billionaires just 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 going to aircrafts - is unlikely to please all critics at the Oct 22-24 luxury jet occasion.

Environmentalists and some experts remain hesitant that biojetfuels, usually blended 50-50 with kerosene, will make a considerable effect on public understandings about luxury travel.

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

Demand from service jet operators for renewable fuels now far surpasses 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 as much as 150 million gallons by 2022.

Corporate charter business and specialists are likewise seeing more interest from customers who want to purchase carbon credits to balance out emissions from their flights.

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

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