Objective:

  • Evaluate shipping-related PM2.5 pollution and mortalities attributable to long-term PM2.5 exposure across Chinese port cities from 2016 to 2020.

Case:

  • Port cities

Methodology:

  • Brute Force method: mortality
  • Change decomposition: Pilling-up decomposition approach

Data Source

  • AIS data and Shipping emission inventory model
  • Weather research and forecasting (WRF) and community multiscale air quality (CMAQ)
  • Population: worldpop
  • Time: OSRM

Findings:

  • Port cities are currently the primary destinations for population migrantion in China
  • High levels of shipping-related PM2.5 concentrations were observed in coastal regions
  • Shipping emissions contribute to PM2.5 pollution at relatively high levels
  • Shipping sector caused 50,200 deaths associated with long-term PM2.5 exposure
  • The most significant decrease in shipping-related PM2.5 was observed along the coastal region, attributable to the marine fuel regulation
