Comparing airfares instead of seat size fairer indicator of passenger carbon emissions
Newswise — Allocating passenger aircraft emissions using airfares rather than travel class would give a more accurate idea of individual contributions, finds a study led by UCL.
Emissions calculators base their estimates on travel class, assuming that someone travelling in a higher class and therefore taking up more space on the plane is responsible for more emissions.
The study, published in Environmental Research Letters, describes how including airfares in calculations shows which passengers contribute the most revenue to the airline operating the aircraft, thereby allowing the plane to fly.
Although in general, premium (business) seats are more expensive than economy, the researchers found when looking at data that many late bookings in economy class, often made for business trips or by high income travellers, cost as much as, or more than, premium seats.
Lead author Dr Stijn van Ewijk (UCL Civil, Environmental & Geomatic Engineering) said: “The paper shows we should follow the money when calculating emissions of individual travellers, as it is revenue that decides whether an airline can operate a plane or not. Someone who has paid twice as much as a fellow traveller contributes twice as much to the revenue of the airline and should be allocated twice the emissions. The seat size of each travel class, which is currently used to allocate emissions, is only a rough approximation of how much passengers pay.”
The researchers say that using airfares to calculate passenger emissions would benefit efforts to address climate change by encouraging people on all budgets to find alternative modes of transport where possible. It would also increase estimates of corporate emissions because it allocates more to expensive late bookings, which are often made for business purposes.
Implementing a tax that is proportionate to the price of the ticket could make the total costs of flying fairer. People buying the most expensive tickets would pay the highest tax, encouraging them to seek alternatives.
Whilst taxes differ between countries, typically the rates are the same across each travel class. Travellers buying expensive tickets, who are more likely to have higher incomes, pay a relatively low tax and are not currently discouraged from flying.
Dr Van Ewijk added: “An equitable approach to reducing airline emissions should not just deter travellers who can only afford the cheapest early bookings but also the big spenders who bankroll the airline. By assigning emissions based on ticket prices, and taxing those emissions, we can make sure everyone pays their fair share, and is equally encouraged to look for alternatives.”
A ticket tax should also take into account the distance flown and the model and age of plane, which can indicate how polluting it is.
The authors used a dataset from the USA to test their fare-based allocation approach. They used the Airline Origin Survey database, which includes ticket fare data, origin and destination, travel class and fare per mile. From this, they calculated the distribution of ticket prices across all passengers on a typical flight.
Based on the price distribution, the authors allocated emissions to passengers, and compared the results with estimates from widely used emissions calculators. Since ticket prices vary strongly by time of booking, the emissions per passenger varied too, far more than on the basis of seat size and travel class.
Using an economic supply–demand model, the researchers estimated how a carbon tax on emissions would affect travellers, depending on whether the emissions the tax applied to were calculated from seat size and travel class, or the airfare. In all scenarios, a tax on emissions calculated from airfares had a more equitable effect because it reduced flying more evenly across income groups.
The researchers hope to effect policy change in calculating and taxing passenger emissions, to ensure travellers on all budgets are encouraged to seek other forms of transport where possible or consider how essential the journey is.

SpaceX to Move Crew Dragon Splashdowns to the West Coast: A New Era in Astronaut Returns
In a significant shift for future missions to the International Space Station (ISS), SpaceX has announced that its Crew Dragon splashdowns will be moving to the U.S. West Coast following multiple incidents involving space debris. This decision marks a pivotal change in the logistics of astronaut returns, moving away from the Atlantic Ocean and potentially concluding the era of East Coast splashdowns as we know it.
The Crew-9 Mission: A Milestone Launch
Scheduled to launch no earlier than August 18, the Crew-9 mission will feature a crew of four astronauts: Commander Zena Cardman and Pilot Nick Hague from NASA, alongside Mission Specialists Stephanie Wilson (NASA) and Alexsandr Gorbunov from Roscosmos. This mission is poised to be the last NASA-led ISS operation to return astronauts to the Atlantic, making it a historic launch in the ongoing partnership between SpaceX and NASA.
The Debris Dilemma
SpaceX’s decision stems from repeated incidents involving the Crew Dragon’s trunk—an essential component housing fuel and electrical supplies—that has fallen back to Earth in uncontrolled descents. These debris falls have been problematic, landing in various locations ranging from Australia to North Carolina. The risk posed by such space debris not only raises safety concerns but also complicates recovery operations.
In a recent press conference, Sarah Walker, SpaceX’s Director of Dragon Mission Management, elaborated on the planned changes. “What we’ll do is implement a software change to complete the deorbit burn before jettisoning the trunk, like we did with Dragon-1,” she explained. This adjustment is intended to ensure that the trunk lands in unpopulated areas of the ocean, minimizing risks associated with falling debris.
Crew Dragon: A Safer, More Predictable Future
The shift to the Pacific coast is not merely a reaction to debris risks; it also offers strategic advantages. The West Coast tends to experience fewer extreme weather events and hurricanes, which could lead to more predictable recovery operations. This change is expected to enhance mission scheduling, allowing for smoother transitions from space to Earth.
SpaceX plans to relocate its Dragon recovery vessel to the Pacific sometime next year to facilitate this transition. The move will not only improve safety for the astronauts but also streamline the recovery process for future missions, starting potentially with Crew-10.
Looking Ahead
As SpaceX continues to innovate and adapt in the realm of human spaceflight, the decision to move Crew Dragon splashdowns to the West Coast reflects a commitment to safety and reliability. The upcoming Crew-9 mission will serve as a fitting close to an era of East Coast splashdowns while paving the way for a new chapter in astronaut return logistics.
With the space industry evolving at a rapid pace, it’s clear that adaptability will be key to ensuring the safety and success of future missions. As we look forward to the Crew-9 launch, the excitement builds not just for the mission itself but for the groundbreaking changes that lie ahead in the realm of space exploration.

The Return of Supersonic Travel: A Nostalgic Pilot’s First Look at the Future
Mike Bannister, former Concorde pilot, tests the futuristic flight deck of Boom Supersonic Overture.
In the heart of the summer, at the bustling Farnborough International Airshow, a significant piece of aviation history intertwined with the future of supersonic travel. Mike Bannister, the former chief Concorde pilot renowned for his extensive experience with the iconic supersonic jet, took a remarkable step into the cockpit of the future. He had the unique opportunity to test the Overture flight deck simulator—introduced by Boom Supersonic—which promises to redefine high-speed commercial flight.
Bridging Generations of Aviation
The Concorde, retired two decades ago, was a symbol of speed and luxury, though encumbered with a complex cockpit crowded with knobs and gauges. Step into the era of Boom’s Overture, and the surroundings transform into something from a sci-fi film. The cockpit unveiled at the airshow, showcased sleek touchscreen interfaces replacing the myriad buttons of the past. The new design, according to Boom, centers around pilot convenience and a stark emphasis on safety.
“For someone who’s spent years flying a plane as iconic as the Concorde, seeing and experiencing the Overture’s advanced controls—it’s exhilarating,” Bannister shared after his simulation ride. “It’s not just about reliving the past speeds but stepping into a future where flying is not just faster but also significantly simpler.”
Simplicity and Safety in Design
The Overture’s designers have not simply focused on speed but brought forward a vision to streamline and enhance the flight experience. Incorporating feedback from real-world pilots, the cockpit is designed with an intuitive layout. Features like force-feedback sidesticks—a modern alternative to traditional yokes—offer pilots tactile feedback, mimicking the real-life responses of the aircraft.
“This new stick, it’s surprisingly intuitive,” remarked Brian Oliver, another former Concorde captain, echoing Bannister’s sentiments. “For someone who flew with yokes, adapting was a breeze, and the pressure feedback feels right.”
High-Tech Enhancements
Among the most futuristic aspects is the augmented reality system, replacing the old droop nose of the Concorde, which was mechanically lowered during takeoffs and landings to aid pilot visibility. Overture pilots will use augmented reality for enhanced situational awareness, benefiting from real-time digital overlays that guide safe landings and navigation.
Feedback from Wings of Experience
The transformation from analog to digital is stark, but former Consexual pilots find the transition smoother than anticipated. John Tye, another voice from Concorde’s past, commented on the ease with which he adapted to the controls: “It tells you something when you can jump into a simulator and almost immediately feel at home.”
Looking to the Skies
As we stand on the cusp of reviving commercial supersonic travel, the innovations in Overture’s cockpit represent a leap forward in making future air travel safer and more efficient. The advancements echo a shared sentiment among those who’ve commanded both Concorde and Overture: the spirit of supersonic travel is evolving, not just returning, and it’s coming with a promise of innovation crafted around the needs of those at the helm.
Boom Supersonic’s ambitions with Overture, reinforced by collaborations with leading aerospace technology experts, mark a committed step toward bringing the world closer, faster. As the prototypes transition into reality, both pilots and passengers may soon look forward to a new era where the allure of supersonic travel is commonplace, marrying nostalgia with groundbreaking advancements. Welcome back to the future of flying, where history meets innovation at mach speeds.
