The American Clean Energy and Security Act (Waxman-Markey Bill)

Climate & Energy Legislation

The U.S. House of Representatives passed the American Clean Energy and Security Act of 2009 (ACES Act), H.R. 2454, on June 26 by a vote of 219 to 212. This comprehensive national climate and energy legislation would establish an economy-wide, greenhouse gas (GHG) cap-and-trade system and critical complementary measures to help address climate change and build a clean energy economy.  The House Energy and Commerce Committee voted 33-25 to approve the ACES Act on May 21.  Committee Chairman Henry Waxman (D-California) and Rep. Edward Markey (D-Massachusetts), chairman of a key subcommittee, introduced the bill on May 15, after floating a discussion draft in March. 

Now that the House has passed the ACES Act, it will be sent to the U.S. Senate for consideration.  The Senate Energy and Natural Resources Committee, chaired by Sen. Jeff Bingaman (D-New Mexico) passed on June 17 an American Clean Energy Leadership Act (S.1462).  This bill addresses several energy issues, including many addressed under the ACES Act.  Several Senate Committees will be addressing aspects of a clean energy and climate bill in September.  These measures will likely be combined to create the Senate counterpart to the ACES Act.  If the Senate passes this combined bill, differences between the Senate and House bills would have to be reconciled, with the final bill passed by both houses, before the bill could be sent to President Obama and signed into law.
