The Environmental Protection Agency (EPA) has taken the first step towards establishing a mandatory greenhouse gas registry. The EPA has sent its proposal for the GHG registry to the White House Office of Management and Budget for final review before it is published in the Federal Register. Publication in the Federal Register will be followed by a public comment period and, likely, by the issuance of a final rule. If a GHG registry is established in a final rule, the registry could support Congressional action on climate change legislation later this year; the registry will provide necessary information and will remove establishing a registry from the list of items that must be contained in a complete piece of climate change legislation. In the 2008 appropriations bill, a June 26, 2009, deadline was set for establishing a GHG registry.
