World only half way to meeting emissions target with current pledges

Governments will need to increase efforts to limit carbon emissions in order to stop climate change, says UN report ahead of Paris summit

Current global efforts to cut greenhouse gas emissions leave about half of the reductions needed still to be found, according to a new analysis by the UN.

The report suggests that governments will have to go much further in their pledges to limit future carbon dioxide emissions, which have been submitted to the UN ahead of the crunch conference on climate change taking place this December in Paris.
