Carbon Monoxide Emission Summary 1985-2007

Carbon monoxide (CO) is a colorless, odorless gas which can be emitted into ambient air as a result of both natural processes and human activity, is a criteria pollutant, and has a national ambient air quality standard (NAAQS) (exit DNR) . Although CO exists as a trace constituent of the troposphere, much of human CO exposure which results in elevated levels of COHb in the blood is due to incomplete fossil fuel combustion. According to USEPA, in 1999, transportation sources of CO accounted for 63% of the total ambient CO emissions in the United States, while other combustion processes (e.g., steam boilers, industrial processes, solid waste disposal) were responsible for most of the rest. For more information please read the USEPA staff paper (exit DNR) on CO.

A graph shows the number of stationary sources reporting carbon monoxide emissions from 1985-2007. The 1985-2007 actual emissions graph shows the reported actual amount of carbon monoxide emitted from stationary air pollution sources from 1985-2007 in the State of Wisconsin. The graph shows how the reported carbon monoxide emissions decreased from approximately 96,000 tons in 1985 to approximately 48,260 tons in 2007.

The carbon monoxide air emissions as reported from 1985-2007 were analyzed, sorted into Source Industrial Classification (SIC) codecategories. SIC codes are four digit numbers assigned to each company supplying a general description of the products manufactured or sold by the company. A pie chart of the major industrial source categories showing the contribution the major source categories emitting carbon monoxide for that year can be seen by choosing any of the following years:

With the exception of Menominee County, all Wisconsin counties reported carbon monoxide emissions from 1985-2007. This information is available in an Excel spreadsheet (XLS, 30KB). The information was sorted in alphabetical order by county. This information does not include emissions from portable sources (i.e. rock crushers, hot mix asphalt plants.)

If stationary source carbon monoxide emissions were reported in a city in at least one year from 1985-2007, this information is available from an Excel Spreadsheet (XLS, 133KB). This information was sorted first, alphabetically by county, and second, alphabetically by municipality in that county. This information does not include emissions from portable sources (i.e. rock crushers, hot mix asphalt plants.)

Information on each reporting facility's actual 2007 carbon monoxide emissions are also available in an Excel Spreadsheet (XLS, 251KB). This information was sorted according to facility identification number.
