“H.R. 2454, American Clean Energy and Security Act of 2009, as ordered reported by the House Committee on Energy and Commerce on May 21, 2009 would make a number of changes in energy and environmental policies largely aimed at reducing emissions of gases that contribute to global warming. The bill would limit or cap the quantity of certain greenhouse gases (GHGs) emitted from facilities that generate electricity and from other industrial activities over the 2012-2050 period. The Environmental Protection Agency (EPA) would establish two separate regulatory initiatives known as cap-and-trade programs—one covering emissions of most types of GHGs and one covering hydrofluorocarbons (HFCs). EPA would issue allowances to emit those gases under the cap-and-trade programs. Some of those allowances would be auctioned by the federal government, and the remainder would be distributed at no charge…CBO has determined that the non-tax provisions of H.R. 2454 contain intergovernmental and private-sector mandates as defined in the Unfunded Mandates Reform Act (UMRA). Several of those mandates would require utilities, manufacturers, and other entities to reduce greenhouse gas emissions through cap-and-trade programs and performance standards. CBO estimates that the cost of mandates in the bill would well exceed the annual thresholds established in UMRA for intergovernmental and private-sector mandates (in 2009, $69 million and $139 million respectively, adjusted annually for inflation).”
