FAA Lets Boeing Certify 35 More 777 Freighters After the 2028 CO2 Cutoff

The US Federal Aviation Administration has granted Boeing an exemption that lets it keep building the 777 Freighter beyond the end of 2027. The decision allows up to 35 newly built 777Fs to receive their first airworthiness certificates after 1 January 2028, the date from which the type no longer meets US fuel-efficiency limits.

The exemption was posted to the public docket on 16 September 2026 and runs until 1 January 2031.

The rule being sidestepped

The deadline comes from 14 CFR Part 38, the US version of the ICAO carbon dioxide standard for aeroplanes, which the FAA finalised in 2024. Boeing told the FAA in its petition that the 777F cannot meet those limits. Without relief, the company would have been unable to deliver a new 777F from 2028 onwards.

Boeing’s planned replacement, the 777-8F, is not ready. It is expected around 2029, roughly two years after the 777-9 passenger version’s targeted 2027 debut, and the 777-9 programme has itself slipped.

Numbers behind the decision

Boeing had 38 unfilled 777F orders at the end of August 2026, six of them attributed to Russia’s Volga-Dnepr. The manufacturer delivered 18 freighters in the first eight months of the year, against 35 in the whole of 2025, and handed over two in August, to Emirates and National Airlines. The type entered service in 2009 and 312 aircraft had been delivered through August.

The FAA’s own estimate puts the effect in context. The 35 additional aircraft would enlarge the worldwide freighter fleet by roughly 2 percent while raising fleet fuel consumption by approximately 8 percent, according to reporting on the exemption.

Competitive angle

The exemption also protects Boeing’s position in the large freighter market ahead of Airbus’s A350F, which is targeting certification and delivery by the end of 2027. A production gap would have left customers choosing between a distant 777-8F and Airbus’s new aircraft.

The carve-out is bounded: a fixed number of airframes, a fixed three-year window, and language that lets the FAA supersede or rescind it. The underlying CO2 rule stands for everything else.

For cargo operators, the practical effect is continuity: 777F deliveries can continue after 2027 if the 777-8F slips further.

The decision is also a reminder of how closely aircraft production and emissions policy are now tied. The CO2 standard was designed to push manufacturers towards more efficient designs, but programme delays can leave a still-selling model out of compliance. The FAA’s approach here was to cap the number of airframes and the time window instead of changing the standard, which keeps the incentive for the 777-8F intact.

Industry observers will also note the timing of the exemption relative to the 777-9 programme. The 777-8F was meant to follow the passenger version by about two years, so every slip in 777-9 certification pushes the freighter further out, and with it the point at which the 777F would otherwise have had to stop. The FAA’s three-year window to 2031 gives Boeing a margin for that.
