150 countries pledge to curb carbon emissions

Countries represent 90% of global carbon emissions, leading to hopes for deal at Paris climate summit

Some 150 countries representing around 90% of the world's carbon emissions have now filed pledges to curb them, dramatically increasing the chances of a deal at the Paris climate summit in December.

The promises made so far would still put the world on track for dangerous global warming rise of 3C (around 9F). But they could be adjusted in the future to meet the 2C target recommended by international scientists, the EU's climate commissioner, Miguel Canete, told a UN conference in Rabat, Morocco.
