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

Fuel manufacturers and jetmakers are eager to showcase novel forms of air travel fuel deemed less hazardous to the environment, from utilized cooking oil to the clearly less attractive meat waste.

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

Their hope is that embracing renewable fuel to suppress emissions could make company jets more attractive to environmentally mindful purchasers - specifically corporations dealing with questions over sustainability from investors or green project groups.

The availability of less contaminating private jets might also spare the abundant and well-known the negative publicity experienced by Britain’s Prince Harry and his spouse Meghan over a current private jet journey to southern France.

Five Gulfstream jets on screen in Las Vegas are using from inedible beef tallow.

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

“All of our product is inedible.”

A few of the other 79 airplane on display screen are anticipated 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 annual carbon emissions worldwide, however can release, typically, as much as 20 times more carbon emissions per guest mile than jetliners, according to the London-based personal charter company Victor.

Prince Harry has defended his occasional use of private jets to ensure his household’s security, and has stated that on the rare occasions he does not fly commercially he offsets his emissions.

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

“Incidents of flight shaming including making use of private jets are regrettable when you think about that our industry has provided fuel performance enhancements of 40% over the past 40 years,” said Bombardier Aviation President David Coleal.

Bombardier believes increased sustainable fuel usage will help the market make inroads with corporations and wealthy buyers. According to market information, billionaires only have a 19% company jet ownership rate.

But even an image transformation - with jets sporting sticker labels like “this aircraft flies on renewable fuels” and organisers adding alternative fuel pumps for going to aircrafts - is unlikely to please all critics at the Oct 22-24 high-end jet event.

Environmentalists and some analysts stay skeptical that biojetfuels, usually blended 50-50 with kerosene, will make a significant effect on public perceptions about high-end travel.

“No amount of Jatropha or Brazil-nut fuel can make business jets look eco-friendly,” said aviation analyst Richard Aboulafia.

Demand from organization jet operators for renewable fuels now far surpasses 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 as much as 150 million gallons by 2022.

Corporate charter business and specialists are likewise seeing more interest from clients 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 business jet utilization study his business just recently finished for a Fortune 500 business.

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