The DDPP has held a series of workshops with the Mitigation Action Plan and Scenarios (MAPS) community to organize a conversation on the lessons learnt from the work conducted so far through two days of technical sessions (December 3&4) and a half-day high-level dialogue (December 6).

The two projects share two fundamental framing principles for the analysis of the low-carbon transition.

First, both have adopted a bottom-up approach as an organizing principle, based on country-level analyses– in 5 countries for MAPS (South Africa, Brazil, Chile, Peru and Columbia) and in the 16 countries of the DDPP (both developed and emerging countries). This approach is consistent with the current paradigm of international climate talks, structured around national contributions (the so-called INDCs), and with the current dynamics that can be observed in which many countries start to integrate low-carbon transformations as core pieces of their development strategies. In order to support these movements, the bottom-up approach of DDPP and MAPS helps revealing the conditions to implement a low-carbon transition according to national specificities (see for instance the detailed analysis of technical and policy conditions of the US deep decarbonization pathways – DDPs).

Second, both projects clearly show that the low-carbon transition can and must be integrated with socio-economic priorities at the national level (see for example the South African DDP analysis which shows that the “peak-plateau and decline” emission pathway is compatible with significant reductions of unemployment and poverty) and that it does not undermine the access to energy services (see for example the analysis of energy costs in the Australian DDPs). The work even reveals that the low-carbon transition can be instrumental to address some of the most difficult issues raised by current development patterns (see discussion on local pollution and health benefits in Chinese – see also IDDRI’s blog Deep decarbonization: an instrumental strategy to control local air pollution in Chinese cities ) and Indian DDPs, on the improvement of energy security in Japanese and Indian DDPs, and on the reduction of energy poverty in the UK analysis).

The comparison of the methodologies developed in MAPS and DDPP also revealed the complementarity of the two approaches, notably with respect to future work to be conducted to inform the post-2015 process. On the one hand, MAPS has worked under official mandates by national governments, which has allowed to organize extensive stakeholder consultations for the design of trajectories and policy packages. This has proved crucial to ensure ownership by domestic audience but it also raised difficulties,
