the administration-backed Energy Policy Act of 2005; facing criticism, Lieberman called the bill imperfect but good for Connecticut, citing a saving of $800 million for Connecticut electricity customers.

Lieberman–Warner Climate Security Act of 2008 Also more commonly referred to as the cap and trade bill, proposed to ration (cap) carbon emissions in the U.S., and tax or purchase (trade) carbon credits on the global market for greater U.S. alignment with the Kyoto Protocol standards and goals.

Gang of 14 On May 23, 2005, Lieberman was one of fourteen senators, dubbed the Gang of 14, who forged a compromise on the Democrats' use of the judicial filibuster, thus avoiding the Republican leadership's implementation of the so-called nuclear option. Under the agreement, the Democrats would exercise the power to filibuster a Bush judicial nominee only in an extraordinary circumstance, and three of the filibustered Bush appellate court nominees – (Janice Rogers Brown, Priscilla Owen and William Pryor) – would receive a vote by the full Senate, which resulted in their confirmation. Lieberman refused to support a filibuster against Supreme Court Justice nominee Samuel Alito. Alito was confirmed by the United States Senate on January 31, 2006, by a vote of 58–42, becoming the Court's 110th Justice. Lieberman voted against the Alito confirmation in the final Senate vote.
