Innovative Pathways for Green Carbon Neutrality in Civil Aviation Airports under Carbon Constraints

As climate change issues were the focus of this generation, the aviation sector was under pressure to decarbonize, such as from long-haul flights and airport operations. This research investigated Beijing Daxing International Airport (PKX) as a pioneering example of green airport development in the context of China’s “Dual Carbon” goals (2030/2060). The study examined PKX’s integration of geothermal energy, sustainable terminal design, and transportation systems to address its accomplishments in terms of carbon neutrality. A mixed-methods, including quantitative energy data analysis, comparative global case studies, and policy evaluation demonstrated the replicability of PKX’s model. The improvements of the recommended policies included unifying green certifications, incentivizing sustainable aviation fuel (SAF), and enforcing transparent carbon disclosure to support the aviation industry’s transition toward sustainability and environmental justice.
