President Barack Obama will target carbon emissions from power plants as part of a second-term climate change agenda expected to be rolled out in the next few weeks, his top energy and climate advisor said on Wednesday.
Obama will take several steps to make tackling climate change a "second-term priority" that builds on first-term policies, Heather Zichal, deputy assistant to the president for energy and climate change, said at a forum sponsored by the New Republic magazine.
"In the near term we are very much focused on the power plant piece of the equation," she said.
On Wednesday in Berlin, Obama said the United States understood it had to do more to fight climate change and he pledged that more action was coming.
"Our dangerous carbon emissions have come down, but we know we have to do more. And we will do more," he said in a speech.
