LAS VEGAS, Oct 22 (Reuters) - At the world’s biggest market show in Las Vegas high-end jets are luring buyers with their sleek shapes, luxurious cabins - and progressively, their use of alternative fuels.

Fuel manufacturers and jetmakers are keen to showcase novel types of aviation fuel considered less damaging to the climate, from utilized cooking oil to the definitely less attractive meat waste.

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

Their hope is that embracing sustainable fuel to curb emissions could make business jets more appealing to environmentally conscious buyers - especially corporations facing concerns over sustainability from shareholders or green campaign groups.

The accessibility of less contaminating personal jets could also spare the rich and famous the negative publicity experienced by Britain’s Prince Harry and his spouse Meghan over a current personal jet journey to southern France.

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

The current waste-based fuels consist of “fats, grease and oils that are byproducts of the food industry,” stated Bryan Sherbacow, primary business officer of Boston-based biofuel manufacturer World Energy, which produces fuel from meat waste utilized by Gulfstream.

“All of our item is inedible.”

Some of the other 79 airplane on screen are expected to be powered by 150,000 gallons of other blends expected to be pumped at the program.

FLIGHT SHAMING

Private jets account for less than 0.1% of overall yearly carbon emissions internationally, however can emit, usually, as much as 20 times more carbon emissions per traveler mile than jetliners, according to the London-based private charter firm Victor.

Prince Harry has defended his periodic use of personal jets to ensure his household’s safety, and has stated that on the unusual occasions he does not fly commercially he offsets his emissions.

But planemakers state incidents such as the furore over his schedule have added fresh obstacles for a market currently making every effort to justify its contribution to cutting business costs.

“Incidents of flight shaming involving the usage of private jets are unfortunate when you consider that our industry has actually provided fuel efficiency enhancements of 40% over the previous 40 years,” stated Bombardier Aviation President David Coleal.

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

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

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

“No quantity of jatropha curcas or Brazil-nut fuel can make business jets look eco-friendly,” said air travel expert Richard Aboulafia.

Demand from service jet operators for sustainable fuels now far exceeds supply and their interest might drive future production, Sherbacow stated.

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

Corporate charter companies and experts are likewise seeing more interest from customers who wish 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 company recently completed for a Fortune 500 business.

“At the end of the day, I believe that rate, expense per hour, range, speed and efficiency, that’s still the (sales) driver. But I believe people are becoming more familiar with the sustainability of operations and how it affects the world.” (Reporting By Allison Lampert, Editing by Tim Hepher and Alexandra Hudson)
