President-elect Barack Obama will focus on selecting his White House Cabinet members for energy, the environment, trade, and agriculture next week, following the placement of his economic and national security team. Climate change policy is a top priority for Obama, who will hold a news conference on Sunday to honor those who have served the nation and may discuss future appointments on a television news program. During Obama's campaign, Kansas Gov. Kathleen Sebelius was a key supporter and is now being considered for a position in the administration, potentially as energy or agriculture secretary. Sebelius' spokesperson stated that she is honored to be considered and is willing to assist the Obama administration in any way possible. The Democratic governor, who was also considered for vice president, has been a strong advocate for renewable energy in Kansas, aiming for 20 percent of the state's energy to come from wind by 2020. Obama has pledged to increase the use of renewable energy sources in the U.S. to lessen reliance on foreign oil suppliers. Industry sources have mentioned potential candidates for the role of energy secretary in the Obama administration, including Dan Reicher from Google.org and John Podesta, who is currently co-chair of the transition team. Carol Browner, who leads Obama's energy and environment task force, is also being considered for a top climate position. It is expected that a decision will be made in the near future, but vetting for these positions is still ongoing. Obama officials are also determining how a climate official in the White House would impact other policy players. Potential candidates for the role of EPA administrator include Lisa Jackson, former commissioner of the Department of Environmental Protection in New Jersey, and Mary Nichols, who served as an assistant administrator for the EPA under Clinton. In terms of trade, Obama met with California Democratic Rep. Xavier Becerra to discuss the chief trade negotiator position, making Becerra a potential candidate for the role. Additionally, Vice President-elect Joe Biden has selected Jared Bernstein as his chief economist and economic policy adviser. Top candidates for agriculture secretary include Democrats John Salazar of Colorado and Sanford Bishop of Georgia, as well as Sebelius, according to two farm lobbyists who spoke anonymously. Bernstein was the deputy chief economist for the Department of Labor from 1995 to 1996.
