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

Fuel producers and jetmakers are keen to display novel kinds of aviation fuel considered less damaging to the climate, from utilized cooking oil to the clearly less glamorous meat waste.

Business jet operators, like airline companies, have bowed to environmental pressure on aviation and dedicated to halving carbon emissions by 2050 compared to 2005.

Their hope is that adopting renewable fuel to suppress emissions might make business jets more appealing to ecologically mindful buyers - particularly corporations facing questions over sustainability from investors or green project groups.

The schedule of less contaminating personal jets might also spare the abundant and famous the unfavorable promotion experienced by Britain's Prince Harry and his better half 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 current waste-based fuels include "fats, grease and oils that are byproducts of the food market," said Bryan Sherbacow, chief commercial officer of Boston-based biofuel producer World Energy, which produces fuel from meat waste utilized by Gulfstream.

"All of our item is inedible."

A few of the other 79 airplane on screen are expected 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 yearly carbon emissions globally, however can release, typically, as much as 20 times more carbon emissions per guest mile than jetliners, according to the London-based private charter firm Victor.

Prince Harry has actually protected his periodic usage of personal jets to ensure his family's safety, and has actually said that on the unusual celebrations he does not fly commercially he offsets his emissions.

But planemakers state events such as the furore over his schedule have actually included fresh obstacles for a market already striving to justify its contribution to cutting business expenses.

"Incidents of flight shaming involving making use of private jets are regrettable when you consider that our market has actually provided fuel effectiveness enhancements of 40% over the past 40 years," stated Bombardier Aviation President David Coleal.

Bombardier believes increased sustainable fuel use will assist the industry make inroads with corporations and rich buyers. According to market data, billionaires only have a 19% service jet ownership rate.

But even an image makeover - with jets sporting sticker labels like "this aircraft flies on sustainable fuels" and organisers including alternative fuel pumps for going to airplanes - is not likely to satisfy all critics at the Oct 22-24 high-end jet event.

Environmentalists and some doubtful that biojetfuels, usually combined 50-50 with kerosene, will make a significant influence on public understandings about luxury travel.

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

Demand from company jet operators for eco-friendly 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, could expand production as much as 150 million gallons by 2022.

Corporate charter companies and specialists are also 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 usage research study his business just recently completed for a Fortune 500 company.

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