EPA announced March 1, 2011, that it was indefinitely postponing the deadline for sources to report 2010 greenhouse gas (GHG) emissions to the agency. According to EPA, the agency needs more time to work on an electronic tool used to facilitate the reports.

A rule the agency issued in October 2009 required sources emitting more than 25,000 metric tons of carbon dioxide-equivalent annually to measure and report their emissions. About 10,000 facilities covered by the rule had to begin measuring emissions January 1, 2010, and report them to EPA on March 31, 2011. 74 Fed. Reg. 56,259 (10/30/09). EPA hopes to have the electronic tool available by the end of summer 2011. See EPA Press Release, March 1, 2011.
