LAS VEGAS, Oct 22 (Reuters) - At the world’s most significant market program in Las Vegas high-end jets are tempting purchasers with their sleek shapes, plush cabins - and significantly, their use of alternative fuels.

Fuel manufacturers and jetmakers are keen to display unique kinds of aviation fuel deemed less damaging to the climate, from used cooking oil to the distinctly less attractive meat waste.

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

Their hope is that embracing eco-friendly fuel to suppress emissions might make business jets more attractive to ecologically conscious buyers - especially corporations facing questions over sustainability from shareholders or green campaign groups.

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

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

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

“All of our product is inedible.”

Some of the other 79 aircraft on screen are expected to be powered by 150,000 gallons of other eco-friendly fuel mixes anticipated to be pumped at the show.

FLIGHT SHAMING

Private jets represent less than 0.1% of overall annual carbon emissions globally, however can produce, on average, as much as 20 times more carbon emissions per passenger mile than jetliners, according to the London-based private charter firm Victor.

Prince Harry has protected his periodic usage of private jets to guarantee his family’s safety, and has stated that on the uncommon events he does not fly commercially he offsets his emissions.

But planemakers state occurrences such as the furore over his travel plan have actually included fresh obstacles for an industry already making every effort to justify its contribution to cutting corporate costs.

“Incidents of flight shaming involving the usage of personal jets are regrettable when you think about that our industry has delivered fuel performance enhancements of 40% over the past 40 years,” stated Bombardier Aviation President David Coleal.

Bombardier believes increased sustainable fuel use will help the industry make inroads with corporations and wealthy buyers. According to industry data, billionaires only have a 19% organization jet ownership rate.

But even an image makeover - with jets sporting sticker labels like “this airplane flies on eco-friendly fuels” and organisers including alternative fuel pumps for checking out planes - is not likely to please all critics at the Oct 22-24 high-end jet occasion.

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

“No amount of jatropha curcas or Brazil-nut fuel can make service jets look eco-friendly,” stated aviation analyst Richard Aboulafia.

Demand from organization jet operators for renewable fuels now far exceeds 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 consultants are likewise seeing more interest from clients who wish to purchase carbon credits to offset emissions from their .

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

“At the end of the day, I think that price, expense per hour, range, speed and performance, that’s still the (sales) motorist. But I believe people are becoming more mindful of the sustainability of operations and how it impacts the world.” (Reporting By Allison Lampert, Editing by Tim Hepher and Alexandra Hudson)
