Our environmental leadership starts at the design board

CFM engineers are among the best in the world, and devote their expertise to designing clean, efficient and quiet engines. In 2007, CFM introduced new Tech Insertion technology that promises you even greater environmental benefit.

An improved combustor design provides as much as a 20 percent reduction in NOx emissions. This ensures the CFM56 meets recently enforced CAEP/6 regulations within a comfortable margin. CO2 emissions and fuel burn are reduced by 1 percent thanks to new aero design of the blades within the high-pressure compressor.

The CFM56 is also a quiet engine. A history of improvements to acoustic panels and engine nacelles has contributed to a significant decrease in noise.
