CFM is lowering emissions
The aviation industry is responsible for about two percent of greenhouse gases emitted worldwide, but this number is expected to rise due to increasing air traffic.
Because they combust air and fuel, aircraft engines emit carbon dioxide (CO2) and oxides of nitrogen (NOx), primary greenhouse gases. CFM has long been a leader in pioneering technologies to reduce emissions of both, as well as hydrocarbons and visible smoke.
We stay well ahead of the toughest environmental regulations by incorporating new technologies into the production standard and by re-invigorating mature fleets through upgrade kits.
Most recently CFM introduced Tech Insertion, breathing new life into the CFM56-5B and -7B fleets.
Tech Insertion engines produce on average 28 percent fewer NOx emissions than the base engines they replace. For each combined airplane takeoff and landing, this reduction is the same as eliminating the NOx released by more than 350 passenger vehicles idling for an hour.
If today’s CFM56-5B and –7B powered fleets were replaced with CFM56 Tech Insertion engines, annual carbon dioxide emissions would be reduced by an amount equal to:
» Removing 66,000 cars from the road for a year; or
» Adding 93,000 acres (37,637 hectares) of forest.
NOx emissions from the CFM56 Tech Insertion engine models are also an average 26 percent lower than 2008 International Civil Aviation Organization (ICAO) regulations allow.
