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

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

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

Their hope is that embracing eco-friendly fuel to curb emissions could make organization jets more appealing to environmentally conscious purchasers - specifically corporations dealing with questions over sustainability from investors or green campaign groups.

The accessibility of less polluting private jets might likewise spare the rich and well-known the unfavorable promotion experienced by Britain's Prince Harry and his wife Meghan over a recent personal jet trip to southern France.

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

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

"All of our item is inedible."

Some of the other 79 airplane on display are anticipated to be powered by 150,000 gallons of other sustainable fuel blends anticipated to be pumped at the show.

FLIGHT SHAMING

Private jets represent less than 0.1% of overall annual carbon emissions worldwide, but can discharge, usually, up to 20 times more carbon emissions per guest mile than jetliners, according to the London-based firm Victor.

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

But planemakers state occurrences such as the furore over his travel plan have included fresh challenges for a market already aiming to justify its contribution to cutting corporate costs.

"Incidents of flight shaming including using personal jets are regrettable when you think about that our market has actually provided fuel effectiveness improvements of 40% over the previous 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 data, billionaires just have a 19% service jet ownership rate.

But even an image remodeling - with jets sporting stickers like "this airplane flies on sustainable fuels" and organisers including alternative fuel pumps for going to planes - is unlikely to please all critics at the Oct 22-24 high-end jet occasion.

Environmentalists and some analysts stay skeptical that biojetfuels, typically mixed 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 organization jets look eco-friendly," said aviation analyst Richard Aboulafia.

Demand from organization jet operators for sustainable fuels now far exceeds 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 approximately 150 million gallons by 2022.

Corporate charter business and specialists are also seeing more interest from consumers who wish to purchase carbon credits to offset emissions from their flights.

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

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