Beginning with Reporting Year 2011, 12 new source categories began reporting GHG data for the first time. EPA added those new source categories to the sectors displayed in the toolFLIGHT's dashboard, as appropriate. Due to the inclusion of new source categories in some of the sectors, the total emissions captured by these sectors increased from 2010 to 2011. This increase did not necessarily correspond to an increase in U.S. GHG emissions from that sector, it may have been due to the increased coverage of the sector. As such, EPA does not show sector level trend data in FLIGHT for sectors that had a change in coverage from 2010 to 2011. Over time, the GHGRP will provide robust trend information for all industrial sectors. Power plants, refineries, minerals and pulp and paper had the same coverage in 2010 as 2011 and EPA has added a bar chart to FLIGHT so users can quickly visualize how emissions changed from 2010 to 2011 for these sources.
