One of President Obama's top environmental and climate advisers announced Tuesday that she would resign in February.
Nancy Sutley is leaving the White House Council on Environmental Quality after five years as its chairwoman, Obama said.
"As one of my top advisers, Nancy has played a central role in overseeing many of our biggest environmental accomplishments, including establishing historic new fuel economy standards that will save consumers money, new national monuments that permanently protect sites unique to our country's rich history and natural heritage, our first comprehensive National Ocean Policy, and our Climate Action Plan that will help leave our children a safer, healthier planet," he said.
As head of the council, Sutley provided on a input range of regulations on everything from energy efficiency to carbon emissions.
Her departure comes after Heather Zichal, the president's top energy and climate adviser, left the White House last month.
