Pathways to a Global Deep Decarbonization

2015 Synthesis report of the Deep Decarbonization Pathways Project (DDPP)

  • Publications 04.12.2015

The 2015 Synthesis report of the Deep Decarbonization Pathways Project (DDPP) presents the cross-cutting results of an international initiative on deep decarbonization in 16 countries in which local research teams have elaborated country-specific deep decarbonization pathways consistent with the 2°C limit. Most of the country reports are available, the German report had been carried out by the Wuppertal Institute.

The Synthesis Report is the successor to the 2014 report of the DDPP with deepened analysis of multiple national scenarios towards the decarbonization objective, assessment of investment needs in low-carbon solutions and socio-economic analysis.

The analysis demonstrates that deep decarbonization of energy systems is possible. The pathways consider a division by more than two of emission by 2050, a target in line with the rates of reductions required at this time horizon for the 2°C limit.

Deep decarbonization appears in addition as compatible with domestic priorities, like a reduction of local air pollution in China, energy security improvements in India or Japan, reduction of energy poverty in the UK or reduction of unemployment and poverty alleviation in the South African case.

The investments required by the transition towards low-carbon technologies appear manageable (1.3% of GDP in 2050). They do not require massive additional investment requirements in the energy sector compared to expected trends, but a massive reorientation towards low-carbon solutions through adequate signals. International cooperation enabling lower costs through massive diffusion reduces significantly the investment needs in the transition.
