Aircraft engine makers Safran SA and General Electric Co.'s subsidiary GE Aviation said Monday that they are launching a program called CFM RISE, with the goal to develop jet engines that will consume less fuel and emit fewer carbon-dioxide emissions.

Through the program, the companies are targeting a reduction of more than 20% in fuel consumption and CO2 emissions compared with today's most efficient jet engines, they said.

"Technologies matured as part of the RISE program will serve as the foundation for the next generation CFM engine that could be available by the mid-2030s," they said.

They will also work on the compatibility of their jet engines with sustainable aviation fuels and hydrogen, with the goal to be able to use 100% of these alternative energy sources in jet engines, they said. Currently, SAFs can be blended at up to 50% with fossil jet fuel in current jet engines.

The companies have also signed an agreement to extend their CFM International 50/50 joint venture--known for supplying LEAP and CFM56 jet engines--until 2050.
