On June 10, the Senate rejected an attempt to block the Environmental Protection Agency from regulating greenhouse gas emissions under the Clean Air Act. By an unexpectedly close vote of 53–47, the resolution failed on a procedural motion to move to a final vote, which led proponents of the resolution or an alternative to be proposed by Sen. Jay Rockefeller (D-WV) to express hope that their path would be the most viable way to move climate and energy legislation this summer. Senate Majority Leader Harry Reid (D-NV) has indicated that the Rockefeller initiative, which would, in his words, “put a two-year timeout on EPA regulations,” will come to a vote later this summer. The Obama Administration had lobbied hard against the original resolution sponsored by Sen. Lisa Murkowski (R-AL), and released a statement saying, “the Senate chose to move America forward, toward that clean-energy economy—not backward to the same failed policies that have left our nation increasingly dependent on foreign oil.” What has not been decided by the Administration and the Democrat leadership in the Senate is how to proceed with a climate/energy bill—the Rockefeller alternative or a more comprehensive measure.
