Waxman sees momentum for Hill climate action early next year

The White House today said the U.S. will offer a provisional domestic emissions-cutting target of 17 percent by 2020 in Copenhagen, which mirrors the 2020 target in the cap-and-trade bill the House approved. The Senate could end up with a different number.

"The debate is not completed yet in the Senate. When the debate is fully completed then we will adjust accordingly," White House climate czar Carol Browner said earlier today.
