Nearly 1,400 companies apply an internal mechanism to price carbon emissions, a jump from 150 just four years ago, according to a report from non-profit group CDP.

Why it matters: The more than eightfold increase shows how seriously corporate America is taking the issue. The internal mechanisms indicate companies are preparing for an eventual external price on carbon, even if that's further off now with President Trump in the White House. It also reflects increasing investor concerns about the risks climate change can bring companies.
