China’s aviation carbon emissions continue to increase and show a growing trend. The inadequate supply of airspace resources and the ineffectiveness of technology-trending aviation carbon emission reduction have exacerbated aviation carbon emissions. This study analyzes the relationship between airspace resource allocation and aviation carbon emissions and reviews the optimal allocation of airspace resources in temporal and spatial dimensions to identify the path of aviation carbon emission reduction. The results show that the efficient allocation of airspace resources is an effective way to reduce aviation carbon emissions. Aviation carbon emissions vary in different phases of aircraft operations, and optimizing the organization of airport slots is important for improving the environmental efficiency of airspace. The airport terminal area is the main airspace for aviation carbon emissions, and building a multi-airport system can enhance the utilization efficiency of regional airspace resources. This study innovatively applies geographic research methods to the topic of aviation carbon emissions in conjunction with airspace. Based on the integration of land and airspace, the research idea of “airspace resource allocation-reducing air congestion-expanding airspace capacity-aviation carbon emission reduction” is proposed to build a co-promotion mechanism for aviation carbon emissions and airspace resource optimization allocation. Its aim is to enrich the content of geographical research, improve the multidisciplinary research paradigm of aviation carbon emissions, and provide practical scientific suggestions to promote China’s aviation carbon emission reduction and green development of the civil aviation industry.
