Q764: Why does FLIGHT show a smaller number of suppliers of petroleum products (Subpart MM) in 2010 and 2011 than subsequent years?

A764. Suppliers of petroleum products submitted data for 2010 and 2011 using a different reporting system than the rest of the GHG Reporting Program (which uses e-GGRT).  Beginning with reporting year 2012, these facilities began reporting in e-GGRT and data from 2012 onwards is contained in FLIGHT and Envirofacts.  Facilities are able to re-submit their 2010 and 2011 data through e-GGRT and FLIGHT displays data for the suppliers that have done so.
