Circular Economy Pathways for Airport Climate Change Mitigation
研究了机场运营商如何在实际中应用循环经济来减少气候影响和回收资源，基于2007-2024年的216份文件分析，总结了脱碳路线图、可持续航空燃料、治理和资源循环等实践，对管理者和政策制定者有参考价值。
ABSTRACT Airport operators face growing climate‐change pressures; the circular economy offers pathways to reduce impacts and recover resources. We examine how airport operators apply the circular economy in practice. We use an exploratory qualitative multicase design based on practitioner‐generated documents (e.g., press releases and sustainability reports) retrieved via Nexis Uni (2007–2024; N = 216). Inductive coding in ATLAS.ti and semantic concept mapping with Leximancer enable cross‐case comparison. The analysis highlights decarbonisation roadmaps (renewables, electrification), sustainable aviation fuels and aircraft innovation, governance and stakeholder engagement, and 5R resource loops across operations and supply chains. The findings systematise circular‐economy practices in a complex infrastructure setting and clarify airport operators' roles within multilevel governance. The study offers actionable cues for managers and policymakers.
