UN Chief: Inaction on climate change 'will cost heavily'

The unrestricted use of fossil fuels must end soon if the world is to avoid dangerous climate change, according to a new report from a UN-backed group.

The Intergovernmental Panel on Climate Change urged that by 2050, most of the world's electricity must - and could - be produced from low carbon sources.

UN Secretary General Ban Ki-moon said: "There is a myth that climate change action will cost heavily. But I am telling you inaction will cost much much more."
