Green Climate Fund: Wealthy countries pledge cash in Berlin

Thirty nations meeting in Berlin have pledged $9.3bn (£6bn) for a fund to help developing countries cut emissions and prepare for climate change.

The Green Climate Fund was to have held at least $10bn by the end of 2014, so the pledge is just shy of the target.

The South Korea-based fund aims to help nations invest in clean energy and green technology.
