The aviation industry has set ambitious goals to reduce its carbon emissions and combat climate change. Central to these efforts is the adoption of Sustainable Aviation Fuel (SAF), which has been heralded as a critical component in achieving net-zero emissions by 2050. However, as large-scale manufacturing of SAF begins, it is becoming increasingly clear that SAF will remain more expensive than traditional kerosene.

The Cost Challenge

Willie Walsh, the chief of IATA, has acknowledged the inevitability of SAF remaining priced at a premium compared to kerosene. This assertion is based on the current state of SAF production, which involves relatively small volumes and higher production costs. Even as production scales up, the cost of SAF is not expected to match that of kerosene. However, this cost disparity is not dissuading airlines from pursuing their carbon emission reduction objectives.

A Necessary Investment

The aviation industry has made significant strides in acknowledging the environmental impact of air travel. IATA had previously projected that SAF could potentially provide up to 65% of the carbon reductions required for the industry to achieve its net-zero emissions target by 2050. This recognition of SAF's crucial role in decarbonizing the sector has led industry leaders to embrace the idea of paying a premium for sustainable aviation fuel.

The Industry's Commitment

In his statement at a conference in Lisbon, Willie Walsh emphasized the aviation industry's readiness to accept the higher cost of SAF as an essential investment in a sustainable future. He asserted that there is no alternative and that the industry is fully committed to achieving its carbon reduction targets. This commitment is reflected in the various initiatives and partnerships being formed to boost SAF production.

The Promise of Scalability

One of the key factors that could potentially mitigate the cost disparity between SAF and kerosene is scalability. Currently, SAF production operates at a relatively small scale, resulting in higher production costs. However, as production volumes increase, economies of scale are expected to come into play, driving down the cost of SAF. Walsh and others in the industry foresee a future where SAF becomes more affordable as deliveries reach a large scale.

Challenges and Solutions

Luis Gallego, CEO of British Airways and Iberia owner IAG, acknowledges that the decarbonization effort will likely make air travel more expensive. However, he believes that the industry can find ways to maintain affordable ticket prices. Gallego highlights the importance of boosting SAF production locally rather than importing it, as importing SAF adds unnecessary costs. This sentiment aligns with the industry's broader efforts to invest in domestic SAF production infrastructure.

Conclusion

The aviation industry's pursuit of sustainability through the adoption of Sustainable Aviation Fuel (SAF) comes with the acknowledgment of a higher cost compared to traditional kerosene. However, this cost is seen as a necessary investment in achieving net-zero emissions by 2050.

Industry leaders, including Willie Walsh and Luis Gallego, are resolute in their commitment to meeting carbon reduction targets, even if it means accepting a premium on SAF. As SAF production scales up, there is hope that the cost gap will narrow, making sustainable aviation a more viable and affordable option for the future. Ultimately, the aviation sector recognizes that the path to sustainability is paved with challenges, but it is a path they are determined to follow for the sake of the planet and future generations.

Tata Group-owned Air India will be introducing new uniforms for its crew members shortly. The uniforms could be introduced when the airline inducts its first wide-body A350 aircraft later this year. Earlier this year, Air India placed orders for 470 aircraft from Airbus and Boeing.

For 60 years, the airline’s flight attendants have worn sarees. But, by November, this might change and a more contemporary attire may be introduced. Fashion designer Manish Malhotra is among those who have been roped in to design the new uniforms, a source said. Discussions on the uniforms for crew are still underway and the finer details of the uniforms are yet to be finalised.

“Churidars will be one of the options for women and the male crew members will wear suits,” an unidentified official said. “The sarees will take a back seat. When I say this, I mean that they may be entirely taken away from the set of uniforms.”

“Various options were given to the airline, which included ready-to-wear sarees that look like sarees but are not draped like the traditional ones. However, they have not been finalised by the management,” a second official claimed.

Air India is currently in the process of merging Vistara with itself. Tata Group holds a 51% stake in Vistara and the rest is with Singapore Airlines. Tata Group is also consolidating its airline business wherein AIX Connect is in the process of getting merged with Air India Express while Vistara is merging with Air India.

Last month, Air India’s new brand identity ‘The Vista’ was inspired by the peak of the golden window frame that signifies “limitless possibilities” and a new aircraft livery. The new uniforms will reportedly be in shades of deep red, aubergine and gold, echoing Air India. Furthermore, Vistara might also adopt the same uniforms after the merger.

Air India last changed its uniform back in 2015 when it was under government control. Air India’s female cabin crew was recognised and known for wearing sarees. The tradition dates back to 1962 when JRD Tata decided to replace the skirt, jacket and hat with the six yards and some other options. The first sarees were sourced from Binny Mills and till today, Air India’s flight attendants can choose between an iconic saree or tunic and pants in the same colour.

Air France-KLM Group announced that Tata Communications, a global digital ecosystem enabler has joined its Corporate SAF program to promote and develop the use of Sustainable Aviation Fuel (SAF). Tata Communications is the first global corporation from India to join this program which actively supports the transition to Sustainable Aviation Fuel and will therefore contribute to the reduction of the CO2 emissions generated by aviation.

Sustainable Aviation Fuels are the most decisive ways of reducing CO2 emissions in the aviation industry. However, the production is currently very limited and SAF represented approximately 0.1% of the global jet fuel use in 2022. The corporate SAF program allows Air France-KLM to partner with organizations to accelerate the production and usage of SAF, and thus pave the way towards making SAF more readily available with the aim to contribute to a more sustainable future in aviation. SAF projects selected by Air France-KLM reduce CO2 emissions by at least 75% compared to conventional jet fuel on a lifecycle basis.

Claude Sarre, General Manager Indian Sub-Continent, Air France-KLM said: “Decarbonizing aviation comes with several challenges, compelling the industry to collaborate with various stakeholders and seek innovative solutions to minimize the environmental impact. As a responsible player, sustainability is embedded at the core of the Air France- KLM Group's strategy, with a strong emphasis on the development and use of Sustainable Aviation Fuels (SAF). We are proud to welcome Tata Communications to the Air France–KLM Corporate SAF Program. This agreement is significant towards raising awareness and addressing sustainability challenges the aviation industry faces. Tata Communications has a strong commitment towards environmental preservation. We are happy to take the first step of this journey in India with them, to make flying more sustainable.”

Kim Bybjerg, Vice President and Head of Continental Europe, Tata Communications, said "With our commitment to be Net Zero by 2035, we are making a strategic shift in our business travels for a sustainable planet. One of our initiatives is to adopt sustainable aviation fuel (SAF) to reduce our carbon emissions. I am pleased to announce our relationship with Air France-KLM and other leading airlines through SAF usage on select routes. I believe our adoption of SAF will encourage employees and more organisations to take up sustainable travel.”

Air France-KLM’s Initiatives Towards CO2 Emissions

Air France-KLM's objective is to reduce its total CO2 emissions per passenger/km by 30% compared with 2019. To achieve this SBTi-validated target, the Group aims to incorporate a minimum of 10% sustainable aviation fuels (SAF) by 2030, beyond the European mandate of 6% for flight departures in Europe by the same deadline. Sustainable aviation fuels are one of the most promising levers for reducing CO2 emissions from aviation. They are currently made from used cooking oils, waste or agricultural and forestry residues. In the future, sustainable synthetic aviation fuels will also be available, made from hydrogen and carbon captured from the atmosphere.

Air France-KLM has implemented a strict sourcing policy and is committed to purchasing only SAFs that do not compete with food or feed, are RSB or ISCC certified for their sustainability, and are not produced from palm oil. SAF projects selected by Air France-KLM reduce CO2 emissions by a minimum of 75% compared with conventional jet fuel on a lifecycle basis and require no engine modifications.

The Air France-KLM Group also announced a substantial order of 50 Airbus A350 aircraft, accompanied by options for an additional 40 units. The order encompasses both the Airbus A350-900 and A350-1000 variants, the distribution of which has not been finalized. Deliveries are scheduled to commence in 2026 and continue through 2030.  Air France-KLM will also be among the launch customers of the Airbus A350 Full Freighter version of the aircraft, having ordered 8 aircraft to renew and expand its cargo fleet.

Air France already operates 22 A350-900s, with 19 still to be delivered. Taking all existing orders into account, Air France-KLM is poised to emerge as the world’s leading operator of the Airbus A350 family, potentially boasting a fleet of up to 99 of these highly efficient aircraft. These newly ordered Airbus A350s will replace older generation aircraft, such as the 26 Airbus A330s and 33 Boeing 777s, operated by both Air France and KLM.  

With these combined orders, covering up to 99 aircraft, Air France-KLM would become the world’s largest A350 family aircraft operator. The Airbus A350 symbolizes the transition to a more sustainable air transport industry. The aircraft consumes 25% less fuel than an equivalent-sized, previous-generation aircraft, thanks to the use of lighter materials: 53% composites and 14% titanium. Its noise footprint is also reduced by 40%.

Fleet renewal is the Group’s primary lever to immediately cut CO2 and noise emissions. Alongside the use of sustainable aviation fuel and eco-piloting techniques, it is one of the pillars of the Group’s decarbonization trajectory, which aims for -30% CO2 emissions per passenger/km by 2030 compared to 2019. Since the 2000s, Air France-KLM has reduced its noise footprint by 40% and the Group continues to work with all its stakeholders to adapt its operations. By 2028, the share of new-generation aircraft in the Air France-KLM fleet will reach 64%, compared to 5% in 2019.
