Paris climate deal at risk unless countries step up plans, says watchdog

International Energy Agency chief says current government pledges to cut greenhouse gas emissions are inadequate

The Paris agreement on climate change risks failure unless countries come forward with more ambitious and detailed plans to cut greenhouse gas emissions, the world's energy watchdog has warned.

The agreement, reached almost a year ago, is only a "framework", said the International Energy Agency on Wednesday, and requires sweeping policy changes among governments around the world to put its aims into force.
