For more than four decades, CFM International has invested in technologies to make our engines cleaner, quieter, and more efficient. Ever more sustainable products: with each new engine model, from the ubiquitous CFM56 family, through to the very latest generation of LEAP engines, CFM has continuously introduced technologies that have significantly improved fuel efficiency, lowered CO2 and NOx emissions, and reduced noise. Although all CFM products comply with the highest standards set by ICAO*, we are committed to do even more.
CFM56-3 high-bypass turbofan reduced fuel burn and CO2 emissions by 24% vs. older low-bypass enginesLEARN MORE
CFM56-5B/-7B Tech Insertion introduced new combustor technology to reduce NOx by 25%LEARN MORE
CFM56-5B PIP and CFM56-7BE reduced fuel burn and CO2 emissions by an additional 2% vs. base enginesLEARN MORE
LEAP engines introduced an impressive package of innovative technologies, setting a new standard, providing a 15% reduction in fuel consumption and CO2 emissions. CFM products brought total improvements of 40% since 1980s.LEARN MORE
Advanced, disruptive technology could bring up to a 20% reduction in fuel burn and CO2 vs. today’s LEAP engine family. Technology is 100% compatible with sustainable fuels.
We believe there is a clear path to get us where we need to be; our industry has been constantly improving fuel efficiency, noise, and emissions as better and better technology has been developed.
GAËL MÉHEUST, CEO/PRESIDENT, CFM
Aviation was the first industry to collectively commit to reducing emissions, with a clear path to achieving its goals. CFM proactively contributes to the sustainable development of aviation.
Safran is one of the founders and leaders of Clean Sky, Europe’s largest research program. Clean Sky is developing innovative, cutting-edge technology aimed at reducing aircraft CO2, gas emissions, and noise levels. GE’s Avio Aero also contributed to Clean Sky, providing engine modules integrated by Safran in a successful demonstrator engine test in 2017.
In the past decade, GE has been part of both phases of the Continuous Lower Energy, Emissions and Noise (CLEEN) Program, in collaboration with the U.S, Federal Aviation Administration and National Aeronautics & Space Administration. CLEEN projects develop technologies that will reduce noise, emissions, and fuel burn and enable the aviation industry to expedite integration of these technologies into current and future aircraft.
In 2008, as a funding member, CFM was a signatory of the landmark Air Transport Action Group (ATAG) Commitment to Action on Climate Change that laid out the strategic vision for aviation’s sustainable development, including the goal of reducing net carbon emissions by 50% by 2050 compared to 2005 levels.
The goal of carbon-neutral aviation calls for proactive, globally cohesive public policies. CFM is working closely with the entire industry to ensure that we achieve this objective together.
reduction net carbon emissions
Reducing fuel consumption is the number-one way to cut CO2 emissions. From its very beginnings, CFM products have reduced carbon emissions by 40% to date. Today, we are actively investing in innovative new technologies that will bring even further reductions in the future. More than 50% of our research and development investment goes toward meeting this goal.
Design and develop new technologies with a focus on continuously improving engine efficiency and reducing CO2 emissions.The next generation of CFM engines will deliver up to a 20% improvement in both compared to today's LEAP engine family.
Support the commercial availability of Sustainable Aviation Fuel (SAF) and ensure that future engines are compatible with 100 percent SAF integration. The company began testing SAF in 2006. Since then, customers have conducted more than 300,000 flights powered by sustainable fuels.
Accelerate the development of radical new propulsion technologies that will pave the way for third-generation aircraft, with:
