Australia sought to change a major international report on climate change to promote a future for coal-fired power and downplay the influence of fossil fuel lobbyists, the environmental group Greenpeace says.

Documents leaked to Greenpeace detail Australia's comments and criticisms of a draft report by the Intergovernmental Panel on Climate Change (IPCC), which is yet to be published.

The Australian government's feedback was published as part of a much wider leak of 32,000 responses from governments and other interested parties.
