On the main source of carbon emissions for single-person flights
In today's world, air travel is on the rise, but its impact on the environment is especially heavy on carbon emissions. For single-person flights, carbon emissions mainly come from several ends.

The first to bear the brunt is the combustion of aircraft fuel. Aircraft rely on fuel for power. The carbon contained in the fuel combines with oxygen during the combustion process, and a large amount of carbon dioxide is emitted into the atmosphere. This is the key source of carbon emissions for single-person flights. Every time a flight takes off, lands, cruises, fuel consumption continues, and carbon emissions also increase. The model and duration of the aircraft are closely related to fuel consumption. Large long-distance passenger aircraft, because of its large power demand, long range, fuel consumption, single-person sharing of carbon emissions is also more; on the contrary, small short-haul aircraft single-person carbon emissions are relatively small.

Furthermore, the operation of airport facilities is also a major source of carbon emissions. Airport lighting, air conditioning, baggage handling and other equipment operate day and night. The lighting system needs electricity to maintain light, the air conditioning system regulates indoor temperature and humidity, and the baggage handling equipment efficiently transports baggage. All of this requires energy supply. At present, most of the energy is still dominated by traditional fossil energy, and the power generation process is accompanied by a large amount of carbon emissions. When passengers are waiting, the carbon emissions generated by airport facilities are scattered among many passengers, but they add up and cannot be underestimated.

In addition, aircraft maintenance and maintenance also indirectly lead to carbon emissions. In order to ensure the safe and reliable flight of aircraft, regular maintenance is essential. During this process, the use of various tools and equipment, the consumption of chemical agents, and the related energy supply all generate a certain amount of carbon emissions. From aircraft fuselage cleaning, parts replacement, to engine maintenance, every step is linked to carbon emissions.

To sum up, carbon emissions from single-person flights are mainly caused by aircraft fuel combustion, airport facility operation and aircraft maintenance. Only by understanding this can we understand the impact of air travel on the environment, and then explore strategies to reduce carbon emissions, so as to promote the harmonious coexistence of the aviation industry and the environment.
