Compared to worldwide emissions (Figure 2), Illinois emissions contain a higher percentage of carbon dioxide. Methane contributes less to the total, primarily because rice, a major methane emitter, is not grown in Illinois. Dlinois Fossil fuel combustion emits 88% of the total greenhouse gas emissions (Figure 3). Landfills and coal mining are the next largest contributors, prima- rily because of their methane emissions. Although land-use change has operated as a CO2 sink (uptake and use of carbon dioxide) in the past, it is currently causing some emissions of CO2 because of greater tree mortality and less new Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Illinois.
