This chapter includes conclusions from the results from the Deep Decarbonization Pathways Project. It is critically important to prepare these country-level deep decarbonization pathways to 2050 as tools for learning and problem-solving. The DDPP highlights the need to introduce long-term backcasting into the scope of climate negotiations and this kind of long-term roadmapping internationally. Very few countries pre-COP21 had developed deep decarbonization pathways, which meant that very few had looked seriously at what it meant to stay within a 2-degree limit, because the 2020 emission reduction goals that were adopted in Copenhagen were too incremental to be consistent with the 2 degree limit. At least two new elements will need to be part of the global deal at COP21 in Paris. First, a global commitment to a deep decarbonization pathway to 2050 consistent with the 2 degree limit that each county will develop and make publicly available. Second, a an absolutely massive and sustained global public-private effort to develop, demonstrate and defuse new low-carbon technologies that are not yet technologically mature or competitive, but are absolutely key to the success of deep decarbonization.
