The provided diagram illustrates the four-stage process through which carbon dioxide emissions are generated and subsequently measured in the operation of popular private jets.
Overall, the process begins with the burning of fuel and concludes with the systematic measurement of the resulting emissions, outlining a linear progression of events.
The initial stage involves Fuel Combustion, where jet fuel is ignited within the aircraft's engines. Following this, Engine Operation occurs. During this phase, the combustion process powers the jet engine, leading to the production of various gases as a byproduct of the burning fuel.
Subsequently, Exhaust Gas Release takes place. This is when the gases produced during engine operation, including carbon dioxide, are expelled from the aircraft into the atmosphere. The final stage is Emission Measurement, where specialised equipment is used to quantify the amount of carbon dioxide released, allowing for data collection and analysis.
