After a couple weeks of increased momentum for the climate talks in Copenhagen, President Obama announced that he will attend the conference. He will be in the region anyway, accepting the Nobel Peace Prize.

An administration official said Obama will travel to the Danish capital Dec. 9, one day before he visits nearby Oslo to officially accept the Nobel Peace Prize.

There had been doubts about whether the president would attend the climate change conference. He had said for weeks that he would go only if his presence would help produce a meaningful result.

While nobody expects a long-term treaty to come out of Copenhagen, there has been growing support for an interim treaty that would include emission reduction targets.

While Obama’s participation in Copenhagen is a good sign, the climate director for the World Wildlife Fund had a good idea for where the President could additionally concentrate his energies if he wanted to contribute to fighting climate change:

“To make good on any promises made in Copenhagen,” (Keya) Chatterjee added, “the President should put the full weight of the White House behind Senate passage of a climate bill in the first part of 2010.”

UPDATE: Here’s the release from the White House, on the flip. Note that it includes an emission reduction target of 17% below 2005 levels by 2020, and 83% by 2050, consistent with the targets in the Waxman-Markey bill:

The White House announced today that President Obama will travel to Copenhagen on Dec. 9 to participate in the United Nations Climate Change Conference, where he is eager to work with the international community to drive progress toward a comprehensive and operational Copenhagen accord. The President has worked steadily on behalf of a positive outcome in Copenhagen throughout the year. Based on the President’s work on climate change over the past 10 months – in the Major Economies Forum, the G20, bilateral discussions and multilateral consultations – and based on progress made in recent, constructive discussions with China and India’s Leaders, the President believes it is possible to reach a meaningful agreement in Copenhagen. The President’s decision to go is a sign of his continuing commitment and leadership to find a global solution to the global threat of climate change, and to lay the foundation for a new, sustainable and prosperous clean energy future.

The White House also announced that, in the context of an overall deal in Copenhagen that includes robust mitigation contributions from China and the other emerging economies, the President is prepared to put on the table a U.S. emissions reduction target in the range of 17% below 2005 levels in 2020 and ultimately in line with final U.S. energy and climate legislation. In light of the President’s goal to reduce emissions 83% by 2050, the expected pathway set forth in this pending legislation would entail a 30% reduction below 2005 levels in 2025 and a 42% reduction below 2005 in 2030. This provisional target is in line with current legislation in both chambers of Congress and demonstrates a significant contribution to a problem that the U.S. has neglected for too long. With less than two weeks to go until the beginning of the Copenhagen conference, it is essential that the countries of the world, led by the major economies, do what it takes to produce a strong, operational agreement that will both launch us on a concerted effort to combat climate change and serve as a stepping stone to a legally binding treaty. The President is working closely with Congress to pass energy and climate legislation as soon as possible.

Underscoring President Obama’s commitment to American leadership on clean energy and combating climate change, the White House also announced today that a host of Cabinet secretaries and other top officials from across the Administration will travel to Copenhagen for the conference. Interior Secretary Ken Salazar, Agriculture Secretary Tom Vilsack, Commerce Secretary Gary Locke, Energy Secretary Steven Chu, and Environmental Protection Agency Administrator Lisa P. Jackson are all scheduled to attend, along with Council on Environmental Quality Chair Nancy Sutley, and Assistant to the President for Energy and Climate Change Carol Browner.

For the first time, the U.S. delegation will have a U.S. Center at the conference, providing a unique and interactive forum to share our story with the world. In addition to working with other countries to advance American interests, U.S. delegates will keynote a series of events highlighting actions by the Obama Administration to provide domestic and global leadership in the transition to a clean energy economy. Topics will range from energy efficiency investments and global commitments to renewables policy and clean energy jobs. The following keynote events and speakers are currently scheduled:

· Wednesday, December 9th: Taking Action at Home, EPA Administrator Lisa P. Jackson
· Thursday, December 10th: New Energy Future: the role of public lands in clean energy production and carbon capture, Secretary of the Interior Ken Salazar
· Friday, December 11th: Clean Energy Jobs in a Global Marketplace, Commerce Secretary Gary Locke
· Monday, December 14th: Leading in Energy Efficiency and Renewables, Energy Secretary Steven Chu
· Tuesday, December 15th: Clean Energy Investments: creating opportunities for rural economies, Agriculture Secretary Tom Vilsack
· Thursday, December 17th: Backing Up International Agreement with Domestic Action, CEQ Chair Nancy Sutley and Assistant to the President Carol Browner
