LAS VEGAS, Oct 22 (Reuters) - At the world’s greatest industry program in Las Vegas high-end jets are enticing purchasers with their smooth shapes, plush cabins - and increasingly, their use of alternative fuels.

Fuel producers and jetmakers are keen to display novel forms of aviation fuel deemed less hazardous to the climate, from utilized cooking oil to the distinctly less attractive meat waste.

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

Their hope is that adopting eco-friendly fuel to curb emissions might make service jets more appealing to environmentally conscious buyers - especially corporations facing concerns over sustainability from investors or green campaign groups.

The accessibility of less polluting personal jets might likewise spare the abundant and popular the unfavorable promotion experienced by Britain’s Prince Harry and his spouse Meghan over a recent private jet trip to southern France.

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

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

"All of our product is inedible.“

A few of the other 79 airplane on display screen are expected to be powered by 150,000 gallons of other renewable fuel mixes anticipated to be pumped at the program.

FLIGHT SHAMING

Private jets represent less than 0.1% of total yearly carbon emissions globally, however can discharge, typically, approximately 20 times more carbon emissions per guest mile than jetliners, according to the London-based private charter company Victor.

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

But planemakers say incidents such as the furore over his itinerary have actually included fresh challenges for an industry currently striving to validate its contribution to cutting corporate expenses.

"Incidents of flight shaming including making use of private jets are regrettable when you think about that our market has delivered fuel efficiency enhancements of 40% over the previous 40 years,” said Bombardier Aviation President David Coleal.

Bombardier thinks increased sustainable fuel usage will assist the industry make inroads with corporations and rich buyers. According to industry information, billionaires just have a 19% company jet ownership rate.

But even an image remodeling - with jets sporting stickers like “this aircraft flies on renewable fuels” and organisers including alternative fuel pumps for checking out aircrafts - is not likely to please all critics at the Oct 22-24 luxury jet occasion.

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

"No amount of jatropha curcas or Brazil-nut fuel can make company jets look eco-friendly,” stated air travel analyst Richard Aboulafia.

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

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

Corporate charter business and experts are likewise seeing more interest from customers who want to buy carbon credits to balance out emissions from their flights.

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

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