FAA clears Boeing to sell 777Fs beyond 2028 emissions deadline

Boeing will be able to continue selling its 777F airframe beyond the introduction of stricter emissions rules due to come into force in 2028 which would have blocked production of the jet, after US regulators granted it a temporary exemption.

The decision is a reprieve for the US planemaker and its freighter programme, while it waits for the delayed 777-8F replacement that is still pending certification.

FAA offers Boeing a three-year reprieve for its 777F

The Federal Aviation Administration (FAA) has authorised sales of a further 35 777Fs, extending the timeline for customers to buy the jet by up to three years.

That pushes the sale period past the previous January 2028 deadline, at which point the new rules come into force curbing emissions from newly manufactured aircraft.

The decision provides Boeing with time to bridge the gap between the current Boeing 777 freighter and its successor, the 777-8F. 

What has Boeing asked for? 

Boeing had claimed that a production gap would have risked $15 billion in US exports. 

The newer freighter is currently expected to enter service around 2029, although its certification schedule has yet to be finalised and has faced delays while the Boeing 777X awaits certification.

Boeing applied for the exemption in December 2025, warning that uncertainty surrounding the certification of the 777-8F would leave it without an alternative for its freighter customers. 

Specifically, Boeing had sought relief from regulations which adopt the International Civil Aviation Organization’s (ICAO) global standard for aeroplane CO2 certification requirements.

The rules prohibit the issuing of an original certificate of airworthiness on or after January 1, 2028, “for certain subsonic jet airplanes that do not meet specific fuel efficiency and greenhouse gas emission limits”.

Boeing said it was seeking an exemption “to allow the certification of 35 Boeing 777 dedicated Freighter (777F) airplanes after January 1, 2028 which are unable to comply with the fuel efficiency limits set by the regulations. The requested exemption would allow the company to meet existing customer demand and maintain production continuity until its more fuel-efficient replacement, the 777-8F, becomes available.”

What are the alternatives to the Boeing 777F? 

The 777F is currently the only large widebody freighter still in production. 

Airbus is working on its own airframe, the A350F. The European planemaker is making progress towards its first flight, with test teams currently validating the freighter’s aerodynamics and systems through extensive ‘Virtual First Flights’ in the simulator.

Airbus teams are also performing ground checks such as smoke detection testing and anemometry calibration. 

The 747-8F is a large freighter which is currently in service, but Boeing ended 747 production in 2023. The final aircraft was delivered to Atlas Air in January 2023.

There are also passenger-to-freighter conversions. 

The 777-300ER passenger-to-freighter conversion offers operators a lower-cost alternative to acquiring a new-build large freighter, however there is a limited supply.

Kalitta Air was the launch operator and currently has seven 777-300ERSFs. 

Emirates SkyCargo put its first 777-300ERSF into service in June 2026, and plans to add further conversions.
