Port congestion and air emissions in ports are two major issues affecting the maritime industry. However, there is little research that investigates how port congestions affect ship emissions near large city ports. In our study, we estimate the change in daily ship emissions of four major Chinese ports from 2020 to 2022 and apply time series models to measure the lagged effects of port congestion on daily ship emissions. Our estimates show that emissions first decrease with the outbreak of congestions, but it then turns to increase after few days in large ports (Shanghai or Ningbo). For other ports, emissions either increase with port congestion (Guangzhou) or there is no significant pattern over time (Tianjin).
