by Christopher Surgenor (GreenAir Online)  At its 77th Annual General Meeting in Boston, IATA approved a resolution committing the global airline industry to achieving net zero carbon emissions by 2050, which it says will align with the Paris 1.5C climate goal. The industry is projecting 10 billion people will be flying in 2050, requiring the abatement of at least 1.8 gigatons of CO2 in that year, about twice the amount emitted by the sector in pre-pandemic 2019. The net zero commitment implies a cumulative total of 21.2 gigatons of carbon will be abated between now and 2050, said IATA. Director General Willie Walsh said “a very significant” $2 trillion investment by the industry will be required out to 2050, needing an aviation-wide collective effort backed by supportive government policy. All industry stakeholders, including governments, must each individually take responsibility to address the environmental impact of their policies, products and activities, demanded IATA. However, the resolution was not supported by the Chinese airline members of IATA, which said their government had a different national target and an attempt to insert a reference in the resolution to UN climate principles was rejected. Walsh told a press conference afterwards that the resolution was binding on all members.

The IATA resolution demands all industry stakeholders commit to addressing their environmental impact and policies “with concrete actions and clear timelines”, including:

• Fuel-producing companies bringing large scale, cost-competitive SAF to the market;
• Governments and air navigation service providers (ANSPs) eliminating inefficiencies in air traffic management and airspace infrastructure;
• Aircraft and engine manufacturers producing radically more efficient airframe and propulsion technologies; and
• Airport operators providing the needed infrastructure to supply SAF, at cost, and in a cost-effective manner.

Subject to progress reviews of the most cost-efficient technology available, IATA’s base scenario foresees the following timelines:

• 2025: With appropriate government policy support, SAF production is expected to reach 7.9 billion litres (2% of total fuel requirement).
• 2030: SAF production is 23 billion litres (5.2% of total fuel requirement) and ANSPs have fully implemented the ICAO Aviation System Block Upgrades and regional programmes such as the Single European Sky.
• 2035: SAF production is 91 billion litres (17% of total fuel requirement) and electric and/or hydrogen aircraft for the regional market (50-100 seats, 30-90 minute flights) become available.
• 2040: SAF production is 229 billion litres (39% of total fuel requirement) and hydrogen aircraft for the short-haul market (100-150 seats, 45-120 minute flights) become available.
• 2045: SAF production is 346 billion litres (54% of total fuel requirement).
• 2050: SAF production reaches 449 billion litres (65% of total fuel requirement).

“SAF will fuel the majority of aviation’s global emissions mitigation in 2050,” stated Walsh. “The recently announced US Grand Challenge to increase the supply of SAF to 11 billion litres (3 billion gallons) by 2030 is a great example of the kinds of policies that will drive aviation sustainability. Similarly, the announcements from several big energy suppliers that they intend to produce billions of extra litres of SAF in the near term are welcome. But we cannot tolerate announcements with no follow-up. To be meaningful, fuel suppliers must be accountable for delivering SAF at cost competitive prices.”

Governments too must support the energy transition through “a holistic policy framework focused on realising cost-effective solutions” and SAF production incentives to increase supply and lower costs, said IATA.   READ MORE
