LAS VEGAS, Oct 22 (Reuters) - At the world’s biggest market program in Las Vegas high-end jets are tempting purchasers with their streamlined shapes, luxurious cabins - and progressively, their usage of alternative fuels.

Fuel manufacturers and jetmakers are eager to display unique forms of aviation fuel deemed less harmful to the environment, from utilized cooking oil to the noticeably less glamorous meat waste.

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

Their hope is that adopting renewable fuel to suppress emissions could make organization jets more attractive to ecologically conscious buyers - specifically corporations dealing with concerns over sustainability from shareholders or green campaign groups.

The availability of less contaminating personal jets could likewise spare the abundant and popular the unfavorable publicity experienced by Britain’s Prince Harry and his better half Meghan over a current private jet journey to southern France.

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

The current waste-based fuels consist of “fats, grease and oils that are byproducts of the food market,” said Bryan Sherbacow, chief commercial 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 aircraft on display are anticipated to be powered by 150,000 gallons of other sustainable fuel blends expected to be pumped at the show.

FLIGHT SHAMING

Private jets represent less than 0.1% of overall annual carbon emissions internationally, but can release, 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 protected his occasional usage of personal jets to guarantee his household’s security, and has actually said that on the uncommon celebrations he does not fly commercially he offsets his emissions.

But planemakers state occurrences such as the furore over his travel plan have included fresh challenges for a market already making every effort to validate its contribution to cutting business costs.

“Incidents of flight shaming involving making use of personal jets are regrettable when you consider that our industry has delivered fuel efficiency improvements of 40% over the past 40 years,” said Bombardier Aviation President David Coleal.

Bombardier thinks increased sustainable fuel use will assist the market make inroads with corporations and wealthy purchasers. According to industry data, billionaires just have a 19% business jet ownership rate.

But even an image transformation - with jets sporting stickers like “this aircraft flies on sustainable fuels” and organisers adding alternative fuel pumps for checking out airplanes - is unlikely to satisfy all critics at the Oct 22-24 luxury jet occasion.

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

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

Demand from organization jet operators for sustainable 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, could expand production up to 150 million gallons by 2022.

Corporate charter companies and consultants are also seeing more interest from customers who desire 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 role in a business jet usage study his business just recently completed for a Fortune 500 business.

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