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

Fuel producers and jetmakers are keen to showcase novel types of aviation fuel considered less hazardous to the climate, from used cooking oil to the definitely less glamorous meat waste.

Business jet operators, like airline companies, have acquiesced ecological pressure on air travel and committed to halving carbon emissions by 2050 compared to 2005.

Their hope is that adopting renewable fuel to curb emissions could make service jets more appealing to environmentally mindful buyers - especially corporations dealing with concerns over sustainability from shareholders or green project groups.

The accessibility of less contaminating personal jets could likewise spare the rich and well-known the unfavorable promotion experienced by Britain's Prince Harry and his partner Meghan over a current private 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 by-products of the food market," stated Bryan Sherbacow, primary commercial officer of producer World Energy, which produces fuel from meat waste used by Gulfstream.

"All of our product is inedible."

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

FLIGHT SHAMING

Private jets account for less than 0.1% of total annual carbon emissions globally, but can produce, typically, up to 20 times more carbon emissions per guest mile than jetliners, according to the London-based private charter company Victor.

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

But planemakers state events such as the furore over his travel plan have actually included fresh challenges for a market already striving to justify its contribution to cutting corporate expenses.

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

Bombardier thinks increased sustainable fuel usage will help the market make inroads with corporations and wealthy buyers. According to market information, billionaires only have a 19% service 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 visiting airplanes - is unlikely to satisfy all critics at the Oct 22-24 high-end jet event.

Environmentalists and some analysts remain doubtful that biojetfuels, typically blended 50-50 with kerosene, will make a substantial influence on public perceptions about high-end travel.

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

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

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

Corporate charter companies and consultants are likewise seeing more interest from clients 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 played a function in a corporate jet utilization study his company recently finished for a Fortune 500 company.

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