Angela Merkel refuses to set deadline to end Germany's use of coal-fired power

German Chancellor Angela Merkel - a veteran of global efforts to curb climate change - has refused to set a deadline for ending her country's use of coal.

Green groups and developing countries had called on Mrs Merkel to use global climate talks in Bonn, to set a date for her country to phase out coal-fired power plants - as she has previously done with nuclear energy.
