World leaders meeting in Cornwall are to adopt strict measures on coal-fired power stations as part of the battle against climate change.
The G7 group will promise to move away from coal plants, unless they have technology to capture carbon emissions.It comes as Sir David Attenborough warned that humans could be "on the verge of destabilising the entire planet".
The coal announcement came from the White House, which said it was the first time the leaders of wealthy nations had committed to keeping the projected global temperature rise to 1.5C.
That requires a range of urgent policies, chief among them being phasing out coal burning unless it includes carbon capture technology.
The G7 will end the funding of new coal generation in developing countries and offer up to £2bn ($2.8bn) to stop using the fuel. Climate change has been one of the key themes at the three-day summit in Carbis Bay, Cornwall.
Leaders of the seven major industrialised nations - the UK, US, Canada, Japan, France, Germany and Italy - are expected to set out plans to reduce emissions from farming, transport, and the making of steel and cement.
They will commit to protecting 30% of global land and marine areas for nature by 2030. They are also expected to pledge to almost halve their emissions by 2030, relative to 2010 levels. The UK has already surpassed that commitment.(BBC)
