Washington - US president-elect Donald Trump says he is "studying" the Paris climate agreement to reduce carbon emissions. But he doesn't want the agreement to put the US "at a competitive disadvantage with other countries".Trump said in an interview with Fox News Sunday that he's wasn't trying to take a wrecking ball to President Barack Obama's legacy. He said: "I don't want to do that at all. I just want what's right."Trump is pointing to lengthy wait times for permit approvals from the Environmental Protection Agency as something hurting job creation.
