CFM International, a joint venture of GE and Snecma, has introduced advanced technology for two of its mature fleets: the CFM56-5B/P and -7B engines that power the Airbus A320 and the Boeing 737 families respectively. Aircraft equipped with the Tech Insertion CFM56 engines produce lower emissions while flying at significantly lower operating cost compared to those with the baseline CFM56-5B/P and -7B engines.

Environmental Benefits
CFM56 Tech Insertion aircraft engines produce on average 28% lower NOx emissions than the engine lines they replace, the base CFM56-5B/P and -7B. If the over 3,500 aircraft in the current CFM56-5B/P and -7B powered fleets had their engines replaced with CFM56 Tech Insertion engines, approximately 11,500 tons of NOx emissions would be avoided per year, equivalent to the annual NOx emissions of over 1.3 million passenger vehicles on U.S. roads.
Operating Benefits
If an airline were to replace engines on 20 of its current-generation CFM56 powered aircraft with the CFM56 Tech Insertion engines, it would save over $479,000 in fuel costs annually, assuming a jet fuel price of $2.50 per gallon.
