Note on emissions from Industrial Processes sector [as referenced in Google's Public Data Explorer]:

This sector produces approximately 2 percent of total U.S. GHG emissions. Emissions from the manufacture of nitric acid, adipic acid, ammonia and urea, HFCF-22, and magnesium are generally not included because of a lack of data. In addition, default estimates of emissions from limestone and dolomite use are unavailable for 1990-93, and estimates of emissions from iron and steel production--a large percentage of total industrial processes emissions in several states--are unavailable until 1997. As a result, many states exhibit "step functions" in their total industrial processes data--that is, a lack of complete industrial processes emissions data prior to 1997 causes an artificial increase in these data beginning in that year.

Note: In an effort to avoid presenting misleading comparisons with other sectors, trends in the industrial processes sector should only be assessed from 1997 through 2007.

The Climate Analysis Indicators Tool (CAIT-US) provides a comprehensive and comparable database of greenhouse gases and other climate-relevant indicators for U.S. states.
