Definition
The release of carbon-based gases, primarily carbon dioxide (CO2), into the atmosphere from the combustion of fossil fuels such as aviation gasoline and jet fuel. In aviation, these emissions are a measured byproduct of engine operation and are tracked because they contribute to atmospheric greenhouse gas levels.
Plain English
The carbon dioxide and similar gases that come out of an aircraft engine when fuel is burned. Burning more fuel produces more of these gases.
Context Anchor
Seen in NextGen discussions about more efficient routes, reduced fuel burn, and the environmental benefits of modern air traffic procedures.
Derivation
From Latin carbo meaning 'coal' or 'charcoal,' and emittere meaning 'to send out.' Together: gases containing carbon being released into the air. The term highlights that what is being measured is the carbon content of what comes out the exhaust.
Why Pilots Care
Efficient procedures developed under NextGen reduce fuel consumption and therefore lower the carbon released per flight.
Grounding Statement
When an aircraft burns less fuel to complete the same flight, it usually produces fewer carbon emissions.
Intuition Check
Carbon emissions does not usually mean black smoke or solid soot in this context. In aviation environmental discussions, it mainly means carbon dioxide released from burning fuel.
Example Sentence 1
By flying a continuous descent approach instead of the traditional step-down, the crew reduced fuel burn and carbon emissions for the arrival.
Example Sentence 2
Pilots follow fuel-efficient procedures that help airlines meet targets for lower carbon emissions.
