Synthesis report of the Deep Decarbonization Pathways Project

The DDPP issued a report on the first phase of its work, preliminary findings on tech nically feasible pathways, at the UN Climate Summit in September 2014, at the invitation of Secretary General Ban Ki-moon. This report summarized each country team’s initial research. In the fall of 2015, all 16 teams published stand-alone reports describing in greater detail their research into national DDPs. This 2015 Synthesis Report provides a cross-cutting analysis of the aggregate results, complementing the executive summary published in September 2015.
