General Electric’s aviation division and its French joint venture partner, Safran, announced Monday that they were developing new aircraft engines that aim to cut emissions by more than a fifth of today’s levels.

GE Aviation and Safran from France jointly produce some of the most widely used aircraft engines as part of their CFM joint venture. Together, they have launched a new program called CFM Rise, which is designed to develop and test new technologies that could go live in the mid-2030s, the companies said.

The global aviation industry contributes about 2% of the world’s carbon emissions, and aircraft manufacturers and airlines have struggled to find ways to reduce this while offsetting the strong pre-pandemic growth in travel demand.

The CFM joint venture between GE and Safran produces engines for the Boeing 737 Max and also for the Airbus A320neo family. Competitor Pratt and Whitney, a unit of Raytheon Technologies, also manufactures engines for the Airbus 320.

The RISE program will work on a technology that could cut fuel consumption by more than 20% and is also compatible with sustainable aviation fuel and hydrogen, they said.

The companies plan to develop an open fan engine that differs from the covered jet engines in commercial aircraft.
