The White House issued a veto threat on Nov. 17 for a resolution from the Republican-led U.S. Senate that would nullify new regulations to cut carbon emissions from power plants, the central piece of President Barack Obama's climate plan.

The Senate sponsors of the motion have said the Environmental Protection Agency regulation, which is also being challenged in U.S. federal court by 26 states and more than a dozen industry groups, would hurt jobs in coal-dependent regions.

The White House said the Senate resolution "threatens the health and economic welfare of future generations by blocking important standards to reduce carbon pollution from the power sector" and said Obama would veto the bill.
