Key  -  In figures 1 & 2, the column on the far left lists different types of HCFC refrigerants and refrigerant blends. Directly to the right of that column is the number of metric tons (MT) sold for each HCFC refrigerant and refrigerant blend. The next four columns break down the percentages of each HCFC refrigerant contained in each blend. The adjoining four column table converts these percentages into MT for each HCFC refrigerant.
When reading the above tables, please take into account the following considerations:
   > These tables cover most of the HCFC refrigerant sales in California, but there may be some missing data. 
   > Note that about 25 percent of the distributors have not reported their 2012 sales information as of May 13, 2013.
   > For 2011 sales, there was probably under-reporting as well, because the reporting requirement was brand new and not all distributors were aware of it.
   > Not included in the tables is the amount of refrigerant "pre-charged" into systems such as residential air-conditioning.  
   > Not included in the tables are internet sales, or any out-of-state sellers that ship directly to the refrigerant user. 
   > The extent of under-reporting is unknown. For example, in 2011, it is estimated that approximately 10,432 MT of refrigerant were emitted from stationary refrigeration and air-conditioning systems in California. The sales of new, presumably replacement refrigerant, are not even half that amount. Of course, many old, large systems are being replaced with smaller systems, which may explain part of that discrepancy. 
         o Note, refrigerant leakage is a small sub-set of actual refrigerant use (leakage) in California. The current tables covering refrigerant leakage only include commercial facilities with at least one system containing more than 0.9 MT of high-GWP refrigerant. Therefore, the tables can only be used on a relative basis.
