LAS VEGAS, Oct 22 (Reuters) - At the world's greatest industry show in Las Vegas high-end jets are luring purchasers with their smooth silhouettes, luxurious cabins - and significantly, their usage of alternative fuels.

Fuel producers and jetmakers are keen to showcase unique types of aviation fuel deemed less damaging to the climate, from utilized cooking oil to the distinctly less glamorous meat waste.

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

Their hope is that adopting sustainable fuel to curb emissions could make company jets more attractive to ecologically mindful purchasers - especially corporations facing questions over sustainability from shareholders or green project groups.

The schedule of less contaminating personal jets might likewise spare the rich and well-known the negative publicity experienced by Britain's Prince Harry and his partner Meghan over a current personal jet journey to southern France.

Five Gulfstream jets on 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 market," said Bryan Sherbacow, primary industrial officer of Boston-based biofuel producer World Energy, which 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 mixes anticipated to be pumped at the show.

FLIGHT SHAMING

Private jets account for less than 0.1% of total annual carbon emissions internationally, but can emit, on average, approximately 20 times more carbon emissions per traveler mile than jetliners, according to the London-based personal charter company Victor.

Prince Harry has actually protected his periodic use of personal jets to guarantee his family's security, and has actually stated that on the uncommon events he does not fly commercially he offsets his emissions.

But planemakers state events such as the furore over his schedule have actually included fresh difficulties for an industry already making every effort to validate its contribution to cutting business costs.

"Incidents of flight shaming including the usage of private jets are unfortunate when you consider that our industry has delivered fuel performance improvements of 40% over the previous 40 years," stated Bombardier Aviation President David Coleal.

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

But even an image remodeling - with jets sporting sticker labels like "this airplane flies on sustainable fuels" and organisers including alternative fuel pumps for going to planes - is unlikely to satisfy all critics at the Oct 22-24 high-end jet occasion.

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

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

Demand from business jet operators for renewable 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, could expand production approximately 150 million gallons by 2022.

Corporate charter companies and consultants are likewise seeing more interest from customers who want to purchase carbon credits to offset emissions from their flights.

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

"At the end of the day, I think that rate, expense per hour, range, speed and efficiency, that's still the (sales) driver. But I believe individuals are becoming more knowledgeable about the sustainability of operations and how it affects the world."
