The U.S. Environmental Protection Agency (EPA) has finalized certain proposed amendments to the Greenhouse Gas (GHG) Reporting Rule. Significantly, the amendments revise the global warming potentials (GWPs) of 23 pollutants, including methane, nitrous oxide, and sulfur hexafluoride, in order to improve the quality of reported emissions and to achieve consistency with GHG inventories prepared internationally. EPA has decided not to finalize in this action, however, the GWPs that it proposed for 26 additional fluorinated GHGs. It may address those compounds in a separate future action. The amendments also include several technical corrections and clarifications, spanning over 25 subparts, and establish confidentiality determinations for the new or substantially revised data elements that result from the corrections and clarifications.
The amendments take effect January 1, 2014.
