North America Commercial Marine Vessel SO2 Air Emissions 2002

This map illustrates the estimated air emissions of sulfur (SOx as SO2) from cargo traffic in shipping lanes serving North American coastlines in the year 2002. SO2 emissions were estimated using a model called the Waterway Network Ship Traffic, Energy and Environment Model (STEEM), which characterizes ship traffic, estimates energy use, and assesses the environmental impacts of shipping. Annual gridded inventories are also available for nitrogen, carbon dioxide, particulate matter, hydrocarbons and carbon monoxide. Source: Wang, C., J.J. Corbett, and J. Firestone. 2007.
