Global economic growth "would not be strongly affected" by rolling back carbon emissions but the cost will rise if action is delayed, the United Nations' climate panel said on Sunday.
"Mitigation cost estimates vary, but…  global economic growth would not be strongly affected," it said, estimating that "ambitious" carbon curbs would shave just 0.06 percentage points annually from global consumption this century, which is targeted to grow by 1.6-3.0 percent annually.
