SAF is an alternative to conventional jet fuel designed to be more environmentally friendly than fossil fuel. Created from renewable resources, such as reclaimed cooking oil and feed stocks, it can reduce carbon emissions by up to 85 percent on a lifecycle basis, according to Neste. SAF can be used in unmodified aircraft engines and fuel delivery systems

United is a chief advocate for legislation to grow the SAF market. The airline has been instrumental in helping secure SAF tax credits in Illinois, as well as Washington, Colorado, and California that encourage airports to purchase SAF.

United is one of the founders of the SAF Coalition, which is described as a consortium of more than 40 airlines, aircraft operators, agricultural enterprises, aircraft and aircraft equipment manufacturers, airports, technology developers, labor unions, and biofuel producers. Its mission is to expand the use of SAF and reduce the reliance on fossil fuels.

In addition to Chicago, the airline has now purchased SAF for airports in Los Angeles, San Francisco, London, and Amsterdam.

“I’m pleased to see United Airlines making this significant move forward by using sustainable aviation fuel daily in flights from O’Hare,” U.S. Senator Tammy Duckworth (D-Ill.) said in a statement. “One of the most important things we can do to make American aviation more sustainable is increase the supply of SAF. At the federal level, I’ve been pushing for the increased use of SAF, and I’m going to keep pushing to increase the supply of American-grown, American-made SAF, a true win-win solution that supports domestic farmers and blenders while reducing our nation’s carbon footprint.”

Illinois Governor J.B. Pritzker echoed the enthusiasm, noting that KORD is one of the busiest hub airports in the United States.

“Illinois’ position as a hub of innovation with some of the most connected airports in the country perfectly aligns with the work of companies like United to build a more sustainable future for travel and reach our shared goal of zero emissions,” Pritzker said.

United Airlines president Brett Hart said tax incentives in Illinois made SAF availability at the airport possible.

“While the market for SAF is still in its infancy, there is a huge opportunity today for airlines and policymakers to work together to support its continued growth,” Hart said.

SAF purchased for United’s fleet is paid for in part through the company’s Eco-Skies Alliance, which allows participating companies to share the “green premium,” or the cost associated with purchasing lower-emission fuels. Since 2021, the alliance has collectively contributed toward the purchase of more than 10.5 million gallons of SAF, according to the company.

Lilium, manufacturer of the seven-seat Lilium Jet, on Thursday announced that Saudia Group—owner of Saudia, the flag carrier of Saudi Arabia and one of the largest airlines in the region—signed a binding sales agreement for the purchase of 50 aircraft, with an option for 50 more. Saudia expects to receive its first jets in 2026.

The deal follows a 2022 memorandum of understanding (MOU) signed by the partners, with plans to establish an eVTOL network across Saudi Arabia.

“The Middle East is a priority for Lilium, and Saudi Arabia will be a very large and exciting market for electric, high-speed regional air mobility,” said Lilium CEO Klaus Roewe.

According to Lilium, the purchase agreement is the largest of its kind for the Middle East-North Africa (MENA) region. Archer Aviation, an eVTOL air taxi manufacturer, earlier this year signed a nonbinding agreement with the United Arab Emirates’ Air Chateau for 100 aircraft.

The signing of Lilium’s deal with Saudia, which includes payment schedules, delivery timelines, performance guarantees, and provisions for maintenance, spare parts, and repairs, was attended by Michael Kindsgrab, Germany’s ambassador to Saudi Arabia.

Saudia will operate the jets through its Saudia Private subsidiary, while Lilium will provide fleet maintenance and support through its recently launched customer service offering. The airline will also assist the manufacturer in certification efforts with Saudi Arabia’s General Authority of Civil Aviation (GACA).

“The eVTOL jets are revolutionizing guest transportation,” said Ibrahim Al-Omar, director general of Saudia. “Their unique vertical takeoff and landing capabilities open up entirely new routes. Imagine traveling up to [108 miles] at speeds of [155 miles] per hour, saving valuable time compared to traditional options. This technology also tackles traffic congestion head-on. Business travelers and exhibition attendees will benefit tremendously from the ease and speed of electric aircraft, allowing them to seamlessly attend and participate in events.”

Al-Omar said use cases for the aircraft will include tourism, sports, entertainment, business conferences, and events out of Saudia hubs in cities like Riyadh and Jeddah.

The companies said they may even ferry worshippers to Mecca during the Hajj and Umrah pilgrimages, which attract millions every year but frequently result in deaths due to heat and crowd density. Lilium and Saudia expect the eVTOL jets will alleviate some of that congestion and reduce travel times by as much as 90 percent.

Other eVTOL manufacturers looking to fly in the country include Joby Aviation, Bristow Group, and Volocopter.

According to Lilium, the company’s order portfolio now includes more than 100 firm orders, 76 options, and hundreds of tentative orders under MOUs. Customers include ASL Group, PhilJets, and UrbanLink Air Mobility, a newly formed company that plans to fly the Lilium Jet in Florida, California, and the Caribbean.

The manufacturer’s EL-2 Goldfinch, which first flew in May, got its first off-runway action when it lifted off from a grassy area smaller than 300 feet near a company facility in Manassas, Virginia.

The company has multimillion dollar contracts across the military, with the Air Force, Army, and Navy all exploring the use of eSTOL technology. The relatively cheap, runway-independent aircraft are viewed as an attractive alternative to conventional fixed wing aircraft and rotorcraft

Electra said the demonstrator completed several takeoffs and landings, climbing at a steep angle of 32 degrees. The aircraft did not require electric charging infrastructure, as many electric vertical takeoff and landing (eVTOL) air taxis do, because its propulsion unit charges the batteries in flight.

All the while, the Goldfinch produced just 55 decibels of noise, equivalent to the volume of a typical conversation, while flying overhead at 500 feet. Electra says its full-scale design, which will carry nine passengers or up to 2,500 pounds of cargo on trips up to 500 sm (434 nm), will be inaudible from the ground at its typical cruise altitude.

It seeks to certify a full-scale model under FAA Part 23 regulations by 2028.

“eSTOL technologies increase the number of available landing sites by orders of magnitude relative to traditional fixed wing aircraft while providing for higher cruise speeds, lower costs, and lower noise than vertical lift solutions,” said JP Stewart, vice president and general manager of Electra. “These first flights from a field demonstrate the beginnings of this strong capability that we will continue to develop.”

Electra’s eSTOL achieves its incredibly short runway requirement through the use of blown lift propulsion. Airflows are guided over the wing into flaps and ailerons that redirect them toward the ground, adding to thrust from the aircraft’s eight electric motors. This allows the vehicle to take off at what Electra describes as neighborhood driving speeds.

Though the manufacturer has several commercial customers lined up for its flagship design, it also views the eSTOL as ideal for airlift operations and agile combat employment, a U.S. Air Force doctrine that calls for the rapid deployment of assets to dispersed locations.

The military will be its first customer, but Electra in January surpassed 2,000 aircraft preorder sales from private partners including JSX, Bristow Group, and JetSetGo.

Dawn Aerospace, manufacturer of the Mk-II Aurora, announced that New Zealand’s Civil Aviation Authority (CAA) has granted it approval to fly at “unlimited” speeds at up to 80,000 feet in altitude. The company is permitted to fly beyond the visual line of sight (BVLOS) of a remote pilot and will not be limited to restricted airspace.

Dawn describes the Aurora as “an aircraft with the performance of a rocket.” According to the company, the aircraft is designed to be the first vehicle capable of flying to the Kármán line—which at about 100 kilometers in altitude is considered the edge of space—twice in one day.

“This unlocks the next major performance milestone for the Mk-II vehicle, namely supersonic flight,” said Stefan Powell, CEO of Dawn. “To the best of our knowledge, this would be the first privately funded [uncrewed aerial vehicle] to break the sound barrier.”

The only successful supersonic airliner, Concorde, which was developed by two now-defunct manufacturers, was retired more than two decades ago. But a new crop of companies, including Dawn and Boom Supersonic, are trying to break the sound barrier again.

Unlike Boom’s Overture, which is being developed as a passenger airline, Dawn’s Aurora is intended for space transportation.

The Mk-II first flew in 2021 and has since completed more than 50 test flights, operating under both jet and rocket power. It last flew in 2023, reaching 200 knots at an altitude of 9,000 feet. But those flights were under a more restrictive license than the one obtained by the company last week.

The goal of the firm’s upcoming campaign, which will comprise about a dozen flights between July and September, is to reach Mach 1.1—the boundary of supersonic speed—at an altitude of 70,000 feet. It hopes to fly to space twice in one day and spend about 180 seconds in microgravity.

If it achieves all objectives, the company believes it would set records for speed, altitude, and climb rate for a self-powered aircraft.

Dawn’s primary business is manufacturing propulsion systems for satellites, and it has 76 thrusters in space. But the company is now looking to enter the suborbital space.

The Aurora is a first-stage demonstrator for the company’s more robust Mk-III—a two-stage-to-orbit model that will take off from the runway and deploy a 250 kilogram satellite at the apex of its flight path.

According to Dawn, it is remotely piloted, low cost, and “rapidly reusable,” designed to fly multiple times per day and between 100 and 1,000 times over its lifespan.

Its engine uses storable, “aircraft friendly” propellants that allow the vehicle to take off without having to wait to be fueled. The engine is also carbon neutral, producing no hydrocarbons during operation.

“Room temperature storable propellants will not boil off, and carbon fiber will not suffer from microcracking, as is common in cryogenic composite tanks,” the company says on its website.

Dawn chose a winged design in order to reduce the risk of an engine malfunction, which could jeopardize the landing—and therefore reusability—of the Mk-II. It will be certified as an aircraft in New Zealand. The model takes off like a conventional aircraft, accelerating to Mach 3 speeds and bending upward into a near-vertical route. On the way down, it descends and glides horizontally back to the runway.

Dawn’s first phase of aircraft testing, conducted with the company’s jet-powered Mk-I, comprised eight hours of flight time across 47 flights. After receiving CAA approval for rocket-powered flight in March 2023, it began flying in just a few weeks.

So far, the Mk-II has made three rocket-powered flights, completed within a three-day span a little over one year ago, as part of the second phase of aircraft development, with the goal of reaching the Kármán line under certification.

According to a blog post from Powell, the current version of the vehicle has a maximum altitude of about 60,000 feet, which will require the company to develop a more powerful variant called the Mk-IIB.

“At full performance, the Mk-II will fly faster and 2.5 times higher than any prior aircraft that takes off from a runway, including the current record holder, the SR-71 Blackbird,” said Powell. “That is the power of bringing rocket performance to an aircraft platform.”

Despite being a demonstrator, Dawn plans to one day use the aircraft for Earth observation, high-speed flight research, in-space science including microgravity research, and even civil and defense applications. According to Powell, the company is already fielding interest in a commercial version of the Mk-II and will be in a “prime position” to roll one out once it reaches the Kármán Line.

The company showcased its Sirius CEO-Jet and Sirius Adventure Jet—the initial entrants into what it claims will be the first family of hydrogen-powered, zero-emission, vertical takeoff and landing (VTOL) capable aircraft—on Thursday at the Move Expo in London.

The models will be powered by a hydrogen-electric powertrain and fuel tank—a propulsion system designed to extend flight time compared to fully electric models. Similar to the Lilium Jet, the aircraft will feature electric ducted fans embedded in fixed wings and canards to provide vertical lift.

Both the CEO-Jet and Adventure Jet are expected to emit less than 60 dBA of noise at a distance of 100 meters—about the volume of a typical conversation—using what Sirius describes as a “deflected vectored thrust” propulsion system. The company claims they will reduce noise by about 95 percent compared to helicopters.

The CEO-Jet, designed to seat three passengers, will serve the private business aviation segment, combining zero-emission flight with luxurious, customizable amenities.

The Adventure Jet, on the other hand, is designed primarily for passenger and cargo transport but can also handle medical evacuations, search and rescue, firefighting, surveillance, and offshore operations. It seats up to two pilots and as many as five passengers, with a maximum takeoff weight of about 7,700 pounds, handling point-to-point trips to remote destinations such as jungles or mountaintops. It will even have an inflatable pontoon, allowing it to glide over water.

The latter design comes equipped with GPS, Doppler radar, very high frequency (VHF) and ultra high frequency (UHF) radio, and a digital autopilot system capable of hover and approach.

“The CEO-JET offers an eco-friendly option for business travel, while the Adventure Jet opens new horizons for global tourism and exploration,” said Alexey Popov, CEO of Sirius.

Founded in 2021, Sirius set out to design an aircraft that could combine the aerodynamics of an airplane with the versatility of a helicopter. The concept for a family of hydrogen-powered business jets first emerged in January, and the company shared more information in the weeks leading up to Move Expo.

The Sirius Jet’s calling card is its propulsion system—a hydrogen-electric powertrain that energizes 28 electric ducted fans, 20 embedded in the wings and eight mounted in the canard. Together with a pressurized cabin, these fans are designed to help the aircraft reach an altitude of 30,000 feet.

The fans are linked individually to one of 28 electric motors, each weighing about 21 pounds and containing a proprietary thermal management system. Air drawn through the jet’s intake passes through a cooling system and into onboard liquid hydrogen tanks. It is then channeled to a fuel cell stack, which has a high weight-to-power density ratio ideal for storing hydrogen.

Within the fuel cell, hydrogen and oxygen react to create water and electricity, the latter of which is directed to a set of battery packs that power the electric motors. The packs recharge during flight, are active for only 90 seconds per flight cycle, and do not need to be replaced, Sirius says. Water, a byproduct, is released through the exhaust valve.

By Sirius’ estimate, it would cost only $500 to fully refill the fuel tank. The company further claims the propulsion system makes its aircraft more efficient than electric VTOL (eVTOL) counterparts.

The Lilium Jet, for example, has a range of about 155 sm (135 nm); the Sirius CEO-Jet will max out at around 1,150 sm (1,000 nm), while the Adventure Jet can reach that range using its additional fuel tanks. Further, the CEO-Jet’s cruise speed and Adventure Jet’s top speed—323 mph (280 knots)—is more than double the Lilium Jet’s (155 mph, or 135 knots).

A potential CEO-Jet network in the U.S. could encompass New York City, Chicago, Kansas City, Missouri, New Orleans, and Miami. The Adventure Jet, meanwhile, could connect San Francisco, Los Angeles, Las Vegas, and Phoenix. According to Sirius, the network would offer “a 4-[time] improvement in travel efficiency compared to conventional methods” such as car or traditional airplane.

At the same time, the hydrogen-powered aircraft are billed as offering the luxury of a conventional business jet. Customers have the option, for example, to customize interior colors, upholstery, amenities—including champagne fridges, custom bathrooms, art installations, and kitchens—lighting, and flooring materials such as marble, hardwood, or carpet. Passengers can even pick the scent they smell when they enter the aircraft.

Both models are equipped with an airframe parachute system that deploys automatically in case of emergency, which Sirius claims reduces risk to “virtually zero.”

Sirius hopes to set up serial manufacturing and obtain certification for the Sirius Jet family before 2028. Next year, it expects to complete an inaugural flight using a demonstration plane and open sales of 50 business jets, with deliveries beginning in 2028. By the end of the decade, it intends to launch a shuttle network across the Americas, European Union, and Gulf Cooperation Council (GCC) countries.

So far, Sirius has received an order from Indian seaplane operator Mehair for 50 Adventure Jets plus 50 options, with another from Indonesian tourism firm Parq Development for five CEO-Jets and Adventure Jets apiece.

The German manufacturer announced it will build a vertiport network for the zero-emissions aircraft in the French Riviera, connecting Monaco, Marseille, Nice, Cannes, Golfe de Saint-Tropez, Aix-en-Provence, and Sophia Antipolis. It aims to launch flights in 2026.

Lilium signed a partnership with Italian vertiport network operator and Airbus partner UrbanV as well as Aéroports de la Côte d’Azur (ACA), which manages Cannes Mandelieu Airport (LMFD), Golfe de Saint-Tropez Airport (LFTZ), and Nice Côte d’Azur Airport (LMFN): the country’s second-largest airport, transporting an estimated 14 million passengers annually. UrbanV is a subsidiary of Aeroporti di Roma, SAVE Group, Aeroporto di Bologna, and ACA, which has committed to achieve carbon neutrality without offsetting its own emissions by 2030.

Lilium’s French Riviera ecosystem will include vertiports at these locations and others under consideration. It is in discussions with local partners to construct additional takeoff and landing sites in Sophia Antipolis, Aix-en-Provence, and Marseille, with the expectation that those agreements will be finalized by year’s end.

“Our territory offers a unique opportunity to fly over the sea to directly connect the main economic, cultural or tourist destinations,” said Franck Goldnadel, chairman of the board of ACA. “A complementary alternative to the helicopter, the eVTOL has its place in the air transport offered from Nice Côte d’Azur.”

Lilium’s flagship jet, combined with electric ground infrastructure from UrbanV, should help remove some emissions from France’s premium and business aviation segments.

Unveiled to the public for the first time last week at the European Aviation Business Convention and Exhibition (EBACE) in Geneva, the aircraft is designed to cruise at 162 knots on city-to-city trips spanning 25-125 sm (22-109 nm). Thirty-six electric ducted fans embedded in the aircraft’s fixed wings provide vertical propulsion and are shielded by flaps during forward flight.

Lilium on Tuesday said it is in talks with several operators interested in purchasing and operating the Lilium Jet in the French Riviera, which accommodates millions of tourists every year. Already, it has an agreement with Austrian private jet operator GlobeAir for the intended purchase and operation of 12 aircraft in the South of France and Italy.

“As a truly European company based in Munich, Germany, with flight testing in Spain and with nascent roots in France, Lilium is extremely proud to be able to assist in the creation of the first regional eVTOL network in the South of France and the first commercially viable network in the E.U.,” said Sebastien Borel, chief commercial officer of Lilium. “We see an enormous potential in this region and cannot wait to see our Lilium Jet fly there soon.”

The multifaceted partnership comes after Lilium entered “advanced” talks with the French government to add a high-volume aircraft production facility in the country. The company is considering several locations and expects to invest up to 400 million euros (about $432 million) into the site over several years. In addition, it already sources aircraft components from French suppliers Saint-Gobain Aerospace, Michelin, and Expliseat.

Lilium in December began building the first of seven production prototype Lilium Jets at its final assembly line in Wessling, Germany. Both it and the French facility are intended to supply fleets globally.

In the U.S., the manufacturer is working alongside newly formed operator UrbanLink Air Mobility, Orlando International Airport (KMCO), and other stakeholders to build an initial eVTOL network in South Florida. It is collaborating with FBO network Atlantic Aviation to electrify more than 100 Atlantic terminals nationwide.

Lilium also hopes to introduce its flagship aircraft in China, the Philippines, the Middle East, South America, and across Europe, the latter in partnership with Lufthansa.

Oscar, well-known for his affinity for trash, has been dubbed United’s chief trash officer and is helping the airline educate the public about sustainable aviation fuel (SAF). 

SAF is made primarily of waste products, such as used cooking oil and agricultural waste feedstocks. According to United, it can be used in combination with conventional fuel in aircraft in accordance with current blending requirements, resulting in lower carbon dioxide emissions.

• READ MORE: Biden Administration Defines ‘Climate-Smart’ SAF Subsidy Program

“SAF is one of the ways we’re planning to reduce our carbon footprint across United’s fleet,” the company said. “Investing in and using more SAF across the entire airline industry will help fly us all toward a lower carbon future.”

Since SAF is basically created from garbage, it made sense to have a trash expert like Oscar to be the company spokesperson for the effort.

United has several short videos starring Oscar the Grouch, beginning with one that shows how he saw a newspaper advertisement for a chief trash officer. With his 30-plus years of experience, how could he miss?

In other videos he plays opposite actual United employees who are excited about the use of SAF at the airline. He interacts with flight crews, sends junk mail to everyone in the world to let them know about United’s plans to power its airplanes on fuel made from waste materials. In another, he has a Zoom meeting with a Generation Z coworker with a sunny and upbeat disposition who wants to know how to spread the word that United is committed to lowering its carbon emissions by using SAF.

The campaign marks the latest SAF initiative for the airline. In February, Embraer announced it would join United Airlines Ventures’ Sustainable Flight Fund, an investment program aimed at increasing the supply of SAF through investment in related startup companies. The airline and its 22 corporate partners have committed more than $200 million to invest in companies working to decarbonize air travel.

The corn is now used to make ethanol, which is added to gasoline, but the move to electric cars will diminish that market. Ethanol can be turned into jet-A, however, and will cut the carbon footprint of jet fuel.

• READ MORE: Boeing Ready to Buy 7.5 Million Gallons of SAF

The administration is proposing subsidies from $1.25 to $1.75 a gallon for farmers but only if they meet some conditions.

The farmers will have to use “climate-smart” farming practices, including the use of approved fertilizers. The resulting fuel must cut greenhouse gas emissions by at least half compared to jet-A made from fossil fuels.

• READ MORE: Business Aviation Industry Groups Aim to Speed Adoption of SAF

The measures were met with approval from the farm community, but environmentalists are less enthusiastic. They are concerned a flood of ethanol-based SAF will hinder development of fuels that are even greener that the corn-based product.

Hong Kong-based Volar Air Mobility, a company developing a fossil fuel-free aerial ride hailing platform that will use electric short takeoff and landing (eSTOL) aircraft developed by a partner in China, is one of the latest to signal interest in the UAE.

The firm signed a memorandum of understanding (MOU) with Abu Dhabi-based Inovartic Investment, laying the groundwork for a partnership that would commercialize a family of zero-emission aircraft in the country.

Agreed upon in advance of the inaugural DriftX—an Abu Dhabi-based conference that last week showcased cutting-edge technology in air, land, and sea transportation—the collaboration will cover aircraft distribution, post-sale services such as maintenance, repair, and overhaul (MRO), crew training, and, potentially, manufacturing and assembly capabilities in the UAE.

“This partnership marks a significant step towards integrating sustainable technologies in aviation, which is crucial for environmental conservation and technological advancement,” said Henry Hooi, CEO of Volar. “This aligns with the goals as outlined in the ‘UAE’s Net Zero by 2050’ agenda.”

Volar seeks to commercialize aircraft that are safe to fly, affordable, and offer on-demand flexibility and zero carbon emissions: a set of criteria it dubs “SAFE.” Its goal is to enhance regional accessibility to private aviation in suburban areas, where environmental concerns and existing aircraft configurations can make traditional airline operations impractical.

Volar’s proprietary, aircraft-agnostic platform is designed to facilitate air taxi ride hailing, complete with booking, check-in, and flight status updates. The first aircraft to join its fleet will be the RX4E: a four-seat eSTOL design being developed by partners at Liaoning General Aviation Academy, which works with the Chinese state-owned aerospace and defense conglomerate Aviation Industry Corporation of China.

The RX4E is built for one pilot plus four passengers, with a maximum takeoff weight just under 2,650 pounds. It will have a range of about 186 sm (162 nm) and cruise speed of 124 mph (108 knots). Batteries can be swapped out in about 10 minutes, minimizing downtime.

Volar deliberately picked an eSTOL configuration over an eVTOL or a drone for several reasons, Hooi told FLYING at DriftX. For one, Hooi said, it offers greater range and endurance. In addition, the company claims on its website that the RX4E will be more affordable and offer greater time savings compared to “conventional” private aviation options. One of the biggest benefits, though, is ease of certification.

“We believe that, from a regulatory perspective, eSTOL will be quicker to be adopted,” Hooi told FLYING.

The RX4E first flew in 2019 and is in the type certification process with China’s Civil Aviation Authority (CAAC). Volar claims the design will be the first commercial four-seat electric aircraft with Part 23 certification, which it expects to obtain by year’s end.

Unlike the tiltrotor designs common in the eVTOL space, Volar’s eSTOL uses a fixed configuration. The company says this will allow it to leverage regulatory frameworks similar to those for existing fixed-wing models.

The design also lacks the unique infrastructure needs of eVTOL aircraft, such as vertiports. In fact, Volar could reduce infrastructure requirements for operators, owing to the eSTOL’s ability to operate from shorter runways. According to Hooi, the company is developing models that can land on land, snow, or water.

Use cases for the eSTOL overlap somewhat with those proposed for eVTOL designs: private aviation, interisland transport, eco-tourism, medical logistics and evacuation, and services in rural areas with limited road infrastructure, to name a few.

But unlike many eVTOL air taxi companies, Volar’s focus is on the developing world, where it believes zero-emission aircraft can derive regional sustainability, accessibility, and economic benefits from aviation.

The firm envisions operations primarily in regions considered part of the “Global South.” It will first launch in the Association of Southeast Asian Nations (ASEAN) countries, a bloc of 10 nations that the company finds attractive due to its rapid economic growth and proximity to mainland China. After that, it will expand into African and Middle Eastern countries, such as the UAE.

“We fundamentally believe that the UAE is a fantastic hub for the potential development of green aviation in the region,” said Hooi.

Hooi said, for example, that he was recently approached with a proposition from a regional government in Southeast Asia. One of the country’s tourism sites lies atop an active volcano, requiring a three-day hike to reach it. The site is visited by as many as 100,000 tourists annually, who often leave a trail of rubbish in their wake.

Volar proposed flying tourists to the top of the volcano using an electric seaplane. Hooi said this could reduce the amount of trash on the trails and attract additional tourists by opening access to people incapable of making the three-day trek. He also suggested that by reducing travel time to the summit, visitors might spend more money at local restaurants and bars, bringing more economic activity to countries that rely heavily on tourism.

“You and I are not going to make an iota of difference if we cannot engage the rest of our communities to participate in collectively working towards a green environment,” Hooi said.
