next decade." There is a large increase in lime and cement manufacturing related emissions between
2009 and 2010 (and going forward). This is due to a change in datasets in these two processes. In
2010, facilities started reporting their GHG emissions directly to the EPA; those emissions are available
to the public through the EPA's Greenhouse Gas Reporting Program (GHGRP). Prior to 2010, in this
report, cement and lime manufacturing related emissions were estimated using the SIT methodologies.

Figure 6-1 shows the historical process emissions from 1990 to 2013 and Figure 6-2 shows the relative
contributions of the GHGs to this sector's emissions from 1990 to 2013. When looking at lime
manufacture, the impact of using the GHGRP's dataset (that is based on directly reported facility
emissions) is clearly shown. Also, HFC, PFC, and SF6 are all highly potent GHGs (see Table 1-1) and as
they continue to replace ODSs the emissions associated with this process will continue to rise.
