Since the beginning of climate discussions, global energy-related carbon emissions have increased by 50% and electricity sector emissions have increased by 65%. The Durban Conference decided to work toward a new global agreement by 2015, which will come into force in 2020. Meanwhile, IEA analysis suggests that if investment patterns do not shift toward low-carbon by 2017, the lock-in of high emissions plants will mean that the 2°C target will be much costlier and more difficult to achieve.
