LAS VEGAS, Oct 22 (Reuters) - At the world's biggest market show in Las Vegas high-end jets are luring purchasers with their streamlined shapes, plush cabins - and significantly, their use of alternative fuels.

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

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

Their hope is that embracing eco-friendly fuel to curb emissions might make organization jets more attractive to ecologically mindful buyers - particularly corporations dealing with concerns over sustainability from shareholders or green project groups.

The schedule of less contaminating personal jets could likewise spare the rich and famous 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 utilizing 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 business officer of Boston-based biofuel manufacturer World Energy, which produces fuel from meat waste utilized 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 eco-friendly fuel mixes anticipated to be pumped at the program.

FLIGHT SHAMING

Private jets account for less than 0.1% of overall annual carbon emissions internationally, but can discharge, typically, approximately 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 use of private jets to ensure his household's safety, and has actually said that on the uncommon events he does not fly commercially he offsets his emissions.

But planemakers state events such as the furore over his itinerary have included fresh difficulties for a market currently making every effort to justify its contribution to cutting business costs.

"Incidents of flight shaming involving making use of private jets are unfortunate when you consider that our market has actually provided fuel efficiency 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 purchasers. According to industry data, billionaires only have a 19% company jet ownership rate.

But even an image remodeling - with jets sporting sticker labels like "this aircraft flies on renewable fuels" and organisers adding alternative fuel pumps for visiting planes - is not likely to satisfy all critics at the Oct 22-24 luxury jet occasion.

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

"No quantity of jatropha curcas or Brazil-nut fuel can make service jets look eco-friendly," said air travel analyst Richard Aboulafia.

Demand from service jet operators for renewable 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 broaden production approximately 150 million gallons by 2022.

Corporate charter companies and experts are likewise seeing more interest from clients who want to purchase carbon credits to offset emissions from their flights.

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

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