Study on factors influencing carbon emissions in civil aviation passenger transport in China
摘要
Abstract
To address the carbon emission issues in civil aviation, this study investigates the factors in-fluencing carbon emissions in civil aviation passenger transport. It constructs an aircraft carbon emis-sion factor model and conducts empirical research on typical aircraft with high utilization rates. The analysis focuses on the effects of aircraft size, range, passenger load factor, and the number of stop-overs on carbon emission factors. The results indicate that advancements in aircraft technology, increased passenger load factors, longer average transport distances, and a higher proportion of large aircraft contribute to a decreasing carbon emission factor in China's civil aviation passenger transport. When only the range is changed, the carbon emission factor decreases as the range increases. For ex-ample, at a 2000 km range, typical aircraft models like A330, B787, A321, and B737 flying at full load and rated cruising speed exhibit a reduced carbon emission factor by 13％ to 22％ compared to an 800 km range. Increasing the number of stopovers leads to an increase in the carbon emission factor, with larger aircraft experiencing a greater increase. For a 1000 km range, the carbon emission factor for A330 and A321 at full load increases by approximately 31％ and 19％, respectively, for one stop-over compared to a direct flight. The increase in carbon emission factor due to a stopover can be offset by the rise in passenger load factor resulting from the same stopover. To maintain a consistent carbon emission factor, large aircraft require a higher increase in the passenger load factor compared to small aircraft. For a 1500 km range, when the passenger load factor for a direct flight is 50％, the passenger load factors for A330 and A321 with one stopover need to reach 62.1％ and 57.7％, respectively. This adjustment aligns the carbon emission factors for stopover flights with those for direct flights. From a carbon emission perspective, medium-sized airliners are more suitable for operating stopover flights than large airliners.关键词
