The aviation industry faces a monumental challenge: eliminating its carbon footprint. But there's no magic bullet – no single invention that will instantly solve the problem. Instead, achieving truly green aviation requires a multi-pronged approach, a symphony of solutions working in harmony. Airbus is demonstrating this perfectly, showcasing the power of combined decarbonization strategies in a single, groundbreaking flight.
Mark your calendars! From November 17th to 21st, 2025, the Dubai Airshow will throw open its doors, promising a glimpse into 'The Future is Here.' This 19th edition is all about cutting-edge tech and revolutionary innovations, and what better stage for Airbus to showcase the synergy of four vital decarbonization levers? These include next-generation aircraft, sustainable aviation fuel (SAF), the Book and Claim system, and carbon dioxide removals (CDR). This flight aims to highlight how each of these elements contributes to shrinking the aviation industry's emissions gap.
Currently, about 30% of the world's operational aircraft are considered 'latest generation,' boasting a significant 20-30% fuel saving compared to their older counterparts. Replacing those fuel-guzzling planes with modern marvels – such as the Airbus A350-1000, which entered service in 2018 and burns, on average, 25% less fuel than older models – is a crucial step towards decarbonization. It’s like trading in your old gas guzzler for a hybrid – an immediate improvement!
And this is where the Airbus A350-1000 comes in. It will embark on a special flight from Toulouse, France, to Dubai, offering a real-world demonstration of these decarbonization levers in action. While implementing all these strategies in routine airline operations remains a rare and complex undertaking, this showcase underscores a critical point: no single technology, standing alone, can propel the aviation industry to its net-zero targets. But here's where it gets controversial... some argue that focusing so heavily on new aircraft distracts from the immediate need to ramp up SAF production. What do you think – is the industry prioritizing the right solutions?
Multiple Levers, Working in Parallel
Industry bodies like the Air Transport Action Group (ATAG) acknowledge the intricate nature of decarbonizing aviation in their Waypoint 2050 report (2nd edition, 2021). Their scenarios, which move away from current trends, consistently identify SAF as the most impactful lever, potentially contributing 53-71% of the required emissions reductions by 2050. This hinges on the industry's dedication to decarbonization and the specific levers that receive the most attention and support. And this is the part most people miss... the report highlights that even with aggressive SAF adoption, market-based measures like carbon dioxide removals are still essential to close the remaining emissions gap by 2050.
The combination of SAF, carbon removals, and other mitigation options offers a practical solution to challenges hindering wider SAF adoption. Inspired by these scenarios, Airbus is leveraging the following approaches to address emissions during the showcase flight:
Deconstructing our SAF, B&C, and CDR Showcase Flight
- Sustainable Aviation Fuel (SAF):
The A350 will fly from Toulouse, Airbus’ operational HQ, to the Dubai Airshow. For this specific flight, the aircraft will use a 35% blend of physical SAF, while the remaining 65% will be conventional aviation fuel (CAF). Toulouse is well-positioned to supply SAF, thanks to the airport's infrastructure and Airbus' dedicated fueling facilities. But what happens when SAF isn't readily available? What options exist for airlines that want to use more SAF than is physically accessible at their location? This is a key challenge, as SAF costs significantly more than traditional jet fuel – anywhere from two to seven times as much, depending on the source.
- Book and Claim (B&C):
An airline might be eager to use SAF and willing to pay the premium, but logistical hurdles could prevent them from physically receiving it. Perhaps they operate in a region far from SAF producers or suppliers. To overcome this, the 'Book and Claim' system allows airlines and airports to benefit from SAF without needing physical delivery. We can use this to virtually replace the CAF on the flight. Through Book and Claim, Airbus purchases SAF emissions reduction certificates from an independent registry, the Roundtable on Sustainable Biomaterials (RSB), an NGO that sets sustainability standards for SAF.
In essence, the Book and Claim mechanism enables a buyer to 'book' a specific amount of SAF and 'claim' the corresponding emission reduction, even if the fuel is used elsewhere. It's like buying renewable energy credits – you're supporting green energy even if your own home isn't directly powered by it. Book and Claim could be a game-changer for scaling up SAF, connecting supply and demand and improving accessibility for potential customers, especially those far from supply points. In practice, the physical SAF is delivered to another operator, which consumes the amount of SAF as indicated by the certificate. But here’s where it gets controversial: some critics argue that B&C lacks transparency and could lead to 'greenwashing' if not properly regulated. Is B&C a legitimate tool for decarbonization, or just a way for companies to appear more sustainable?
- Carbon Dioxide Removals (CDR):
Even after maximizing SAF use (through physical SAF and Book and Claim certificates), some emissions will inevitably remain. To neutralize these residual emissions, Airbus will use carbon dioxide removal (CDR) units. CDR involves physically removing carbon dioxide from the atmosphere and storing it – a credible measure for addressing remaining emissions. For this flight, Airbus has selected CDRs from reforestation projects in Mexico, certified by the Climate Action Reserve (vintage 2022-2023). This is like planting trees to offset your carbon footprint – a direct effort to remove CO2 from the air.
What Does This Showcase Reveal About Aviation’s Path to Decarbonisation?
The entire industry must unite to tackle decarbonization, from airlines and airports to fuel producers, OEMs like Airbus, and regulatory bodies. We are playing our part by increasing SAF use in our operations with fuel providers like TotalEnergies, participating in the SAFFA Fund alongside AirFrance-KLM Group and Qantas, and investing directly in SAF producers like LanzaJet.
Regarding Book and Claim, Airbus has launched its own Demonstrator in collaboration with RSB, aiming to facilitate demand from smaller customers and connect it with supply, making SAF more accessible. Airbus is also advocating for the recognition of Book and Claim. Currently, it is not recognized by regulated markets like the EU Renewable Energy Directive or CORSIA, however Airbus believes this could be a powerful lever to make SAF more accessible.
Aviation's journey to net-zero carbon emissions by 2050 is a marathon, not a sprint. It demands hard work, investment, regulatory support, and the unwavering commitment of all industry players. The industry agrees that a multi-faceted approach is key. This flight embodies that idea, taking it to the skies.
