The influence of ship emissions on air quality in Mexico and the potential improvements resulting from the ratification of Annex VI of the International Convention for the Prevention of Pollution from Ships (Marpol Convention) and the establishment of a Mexican emission control area (ECA) have been evaluated using the WRF-Chem air quality model. The model’s performance for the base year (2011) was evaluated against ambient air quality data from monitoring stations, as well as meteorological parameters. The modeling results for prospective scenarios in 2030 were used to feed the Environmental Benefits Mapping and Analysis Program (BenMAP). Two main pollutants (ozone and particulate matter less than or equal to 2.5 micrometers) were selected to evaluate the health and economic impacts of improvements in air quality resulting from reductions in the concentrations of these pollutants. Emissions from ships in the proposed Mexican ECA region contribute a significant number of cases of adverse health effects, especially in highly populated coastal areas. The implementation of an ECA for Mexico is expected to yield important health benefits for its inhabitants.
