LAS VEGAS, Oct 22 (Reuters) - At the world’s greatest market program in Las Vegas high-end jets are tempting buyers with their sleek silhouettes, plush cabins - and significantly, their usage of alternative fuels.

Fuel producers and jetmakers are eager to showcase novel forms of aviation fuel deemed less damaging to the climate, from utilized cooking oil to the definitely less attractive meat waste.

Business jet operators, like airlines, have actually acquiesced environmental pressure on aviation and dedicated to cutting in half carbon emissions by 2050 compared with 2005.

Their hope is that embracing sustainable fuel to curb emissions might make company jets more attractive to environmentally conscious purchasers - especially corporations facing concerns over sustainability from investors or green campaign groups.

The availability of less polluting personal jets might also spare the abundant and popular the negative publicity experienced by Britain’s Prince Harry and his wife Meghan over a current personal jet trip to southern France.

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

The latest waste-based fuels include “fats, grease and oils that are byproducts of the food industry,” stated Bryan Sherbacow, chief industrial 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 sustainable fuel mixes expected to be pumped at the program.

FLIGHT SHAMING

Private jets account for less than 0.1% of overall annual carbon emissions internationally, but can emit, on average, up to 20 times more carbon emissions per guest mile than jetliners, according to the London-based private charter firm Victor.

Prince Harry has safeguarded his periodic use of personal jets to ensure his family’s security, and has stated that on the rare occasions he does not fly commercially he offsets his emissions.

But planemakers state events such as the furore over his schedule have included fresh challenges for an industry currently making every effort to validate 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 delivered fuel efficiency enhancements of 40% over the previous 40 years,” said Bombardier Aviation President David Coleal.

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

But even an image makeover - with jets sporting sticker labels like “this airplane flies on eco-friendly fuels” and organisers adding alternative fuel pumps for going to aircrafts - is not likely to satisfy all critics at the Oct 22-24 luxury jet event.

Environmentalists and some analysts remain doubtful that biojetfuels, generally mixed 50-50 with kerosene, will make a considerable impact on public perceptions about luxury travel.

"No quantity of jatropha curcas or Brazil-nut fuel can make organization jets look eco-friendly,” stated aviation expert Richard Aboulafia.

Demand from service jet operators for eco-friendly fuels now far goes beyond supply and their interest might drive future production, Sherbacow said.

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

Corporate charter companies and specialists are also seeing more interest from consumers who desire to buy carbon credits to offset emissions from their flights.

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

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