President-elect Barack Obama has not yet officially announced his choices to fill key environmental posts in his administration, but the word is now out on the street. Transition-team officials say that Lisa Jackson will head the U.S. EPA, Steven Chu will be secretary of energy, Nancy Sutley will head the White House Council on Environmental Quality, and Carol Browner will fill a new post that some are calling “energy czar.” The secretary of interior position is still up in the air. Obama is expected to formally introduce his environmental team next week.
