The staff change is the latest in a string of departures from the Obama administration following the Republican takeover of the House in November.
Browner, the current coordinator of energy and climate policy, will remain in her post as long as necessary to guarantee a smooth transition, Reuters reports. It was not immediately clear whether she would be replaced at all.
“On the question of what will happen to the position, the president’s commitment to these issues will of course continue but any transition of the office will be announced soon,” an administration official said.
Climate change was one of the major issues on Obama’s agenda, but the ambitious cap-and-trade program he promised in his 2008 campaign has stalled.
Browner headed the Clinton-era EPA and was instrumental in the Obama administration’s handling of the Deepwater Horizon oil spill last spring.
