The woman who led the world to a global climate change agreement has a message for Australia: "You really do have to see that we are at the Kodak moment for coal."
Christiana Figueres, until last year the executive director of the United Nations Framework Convention on Climate Change, doesn't mean happy snaps for the family album.
Rather, the decimation of the once dominant photographic company Kodak by digital change — in the same way that coal-fired power is being eclipsed by renewable energy.
She hopes to see coal, like those sentimental moments in time captured in photographs, confined to history — with the world remembering the contribution the fossil fuel has made to human development, while recognising the need to retire it as a fuel source because of its contribution to global warming.
And, she says, it's happening.
