Core Research
Research 1: Evolution and Drivers of Air Passenger Carbon Emissions Inequality at the City Level.
A long-term city-level air passenger CO₂ emissions inventory was constructed for 43 cities across five major urban agglomerations in China from 2014 to 2022. The MLD and IDA approaches were combined to quantify aviation emissions inequality and identify its major drivers. Economic factors, particularly the transport economic ratio, population, and per-capita GDP, were the primary contributors to inequality, while spatial benchmarking was used to develop differentiated city-level mitigation strategies.
Main contributions of Research 1:
1) Developed a long-term city-level aviation CO₂ emissions and inequality assessment framework.
2) Identified the technological, operational, market, and socioeconomic drivers of aviation emissions inequality.
3) Proposed city-specific decarbonization strategies through spatial benchmarking.
Research 2: Underestimated Committed Aviation Emissions.
A transfer-aware framework was developed to reassess committed aviation emissions by incorporating aircraft redistribution, operational reassignment, and delayed scrapping. By integrating aircraft transaction records, retirement information, aircraft characteristics, and origin–destination operations, the study examined how aircraft move across regions and continue operating under different route structures and retirement patterns. This framework extends conventional static fleet accounting to a global stock-flow perspective and provides a more comprehensive basis for evaluating long-term aviation emissions and decarbonization pathways.
Main contributions of Research 2:
1) Developed a transfer-aware analytical framework for committed aviation emissions by incorporating aircraft mobility and cross-regional redistribution.
2) Integrated aircraft transaction, retirement, and origin-destination operational data to characterize aircraft transfer pathways and post-transfer operating patterns.
3) Extended committed emissions accounting from a static fleet perspective to a global stock-flow perspective, incorporating transfer, reassignment, and delayed scrapping processes.
