Fossil fuels should be phased out by 2100 says IPCC
The unrestricted use of fossil fuels should be phased out by 2100 if the world is to avoid dangerous climate change, a UN-backed expert panel says.
The Intergovernmental Panel on Climate Change says in a stark report that most of the world’s electricity can – and must – be produced from low-carbon sources by 2050.
If not, the world faces “severe, pervasive and irreversible” damage.
The UN said inaction would cost “much more” than taking the necessary action.
The IPCC’s Synthesis Report was published on Sunday in Copenhagen, after a week of intense debate between scientists and government officials.
It is intended to inform politicians engaged in attempts to deliver a new global treaty on climate by the end of 2015.
The report says that reducing emissions is crucial if global warming is to be limited to 2C – a target acknowledged in 2009 as the threshold of dangerous climate change.
The report suggests renewables will have to grow from their current 30% share to 80% of the power sector by 2050.
In the longer term, the report states that fossil fuel power generation without carbon capture and storage (CCS) technology would need to be “phased out almost entirely by 2100”.
