### Summary

    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.

  Abstract (Description)

        Este mapa ilustra una estimación de las emisiones atmosféricas de azufre (SOX y SO2) del tráfico de carga en las rutas de navegación hacia las costas de América del Norte en 2002.

        Las emisiones de SO2 se calcularon aplicando un modelo denominado «energía y medio ambiente del tráfico de embarcaciones en la red de rutas de navegación» (Waterway Network Ship Traffic, Energy and Environment Model, STEEM) que caracteriza el tránsito naviero, calcula su uso de energía y evalúa las repercusiones ambientales de las embarcaciones. También se dispone de inventarios anuales reticulados para las emisiones de nitrógeno, dióxido de carbono, partículas, hidrocarburos y monóxido de carbono.

        Cette carte illustre les estimations d’émissions atmosphériques de soufre (SOX comme SO2) par les navires de charge ayant circulé dans les couloirs de navigation le long des côtes nord-américaines en 2002.

        On a évalué les émissions de SO2 à l’aide d’un modèle baptisé Waterway Network Ship Traffic, Energy and Environment Model (STEEM), qui caractérise le trafic maritime, et évalue la consommation d’énergie et les effets sur l’environnement du transport maritime. Il existe également des inventaires annuels répartis sur des grilles pour l’azote, le dioxyde de carbone, les particules, les hydrocarbures et le monoxyde de carbone.

Supplemental information

      The Commission for Environmental Cooperation (CEC) is an international organization created by Canada, Mexico, and the United States of America under the North American Agreement on Environmental Cooperation (NAAEC), which came into force at the same time as the North American Free Trade Agreement (NAFTA). The CEC was established to address regional environmental concerns, help prevent potential trade and environmental conflicts, and to promote the effective enforcement of environmental law. As of 2020, the CEC operates in accordance with the Environmental Cooperation Agreement, which entered into force at the same time as the CUSMA/T-MEC/USMCA trade agreement.

      This data set is available in several formats, including Shapefile, Map package, and a PDF Map, along with other files appropriate to particular format, such as .lyrx and .qlr files.

### Lineage ▼►

Lineage statement

      The atmospheric modeling that will use our North American ship emissions inventory. This consensus resulted from several meetings with the SECA team, combined domain extents provided by ARB and the U.S. EPA. Originally, we proposed conforming to the most resolved geographic grid size used by ICOADS, which is 0.1 x 0.1 degrees. However, finer resolutions became possible with the application of STEEM routing analyses, and atmospheric modelers requested a resolution as fine as 4 km x 4 km (16 km2). The limitation on resolution for raster images was the computational time to resolve route segments into the final grid sizes.

      Our inventory deliverables, therefore, required a projection that gridded cells in kilometers, and we delivered the North American inventory estimates for each pollutant with the following projection parameters from ESRI’s ArcGIS software.
