| contents | Beijing Daxing International Airport has been promoted as a model of green infrastructure under China's ecological modernization agenda. Featuring energy-efficient design, renewable energy systems, and smart environmental controls, the airport embodies multiple green commitments. This study evaluates its environmental outcomes using multi-source remote sensing data -- including NDVI, NDBI, Land Surface Temperature (LST), VIIRS night-time lights, and PM2.5 -- from 2014 to 2019. Through spatial and temporal comparisons, we assess landscape-level changes during and after construction. Findings indicate partial gains from green initiatives but also reveal substantial vegetation loss, increased built-up surfaces, and intensified surface temperatures. The results suggest a gap between sustainable design and ecological impact. We propose a remote-sensing-based framework for evaluating future infrastructure projects, emphasizing the need for spatially explicit, independent monitoring to ensure environmental accountability. |
