The IEA’s 2015 report sheds light on the essential elements of an energy sector transition that would be consistent with limiting the rise in global temperature to “well below 2°C,” as set out in the Paris Agreement. It aims to analyse the scale and scope of investments in low-carbon technologies in power generation, transport, buildings and industry (including heating and cooling) that are needed to facilitate such a transition in a cost-effective manner, while also working towards other policy goals.
