This China country report by the country team in the Deep decarbonization pathway project (DDPP) summarize the key findings of the technical pathways
developed by the Chinese team, with a view to achieve deep reduction in the longer term for China.

This report explores what is required to achieve deep decarbonization in Germany and reach the German target of reducing domestic GHG emissions by 80% to 95% by 2050 (compared with 1990). Potential decarbonization pathways for Germany are illustrated by means of three ambitious scenarios.

This report has studied the feasibility conditions of two different decarbonization pathways: one focusing on energy efficiency to obtain a strong reduction in energy demand (this pathway is highly consistent with objectives of the law on Energy Transition for Green Growth) and the other one considering potential limits to energy demand reduction and thus implying a higher level of decarbonized energy supply.

The UK has been a leader in legislating long-term climate mitigation targets and crucially setting a binding institutional and reporting framework to ensure that a series of 5-year carbon budgets are adhered to. In summary, this report seeks to demonstrate, alongside other countries, that a 2°C target could be achievable, and still remains an important political goal to aim for at the coming climate talks in Paris.

This report presents the results of a deep decarbonization analysis conducted by the Indonesian Country Research Team consisting of researchers from Institut Teknologi Bandung, particularly the Center for Research on Energy Policy–Institut Teknologi Bandung and Centre for Climate Risk and Opportunity Management–Bogor Agriculture University. Our objective is to explore potential development pathways by which the Republic of Indonesia could achieve the deep decarbonization of its economy, to the level where it would contribute to the worldwide endeavor of limiting global temperature increases to less than 2°C.

The analysis consider
two development scenarios for India and assess alternate roadmaps for transiting to a low carbon economy consistent with the globally agreed 2°C stabilization target. The report does not consider existence of a reference scenario of a world with unmitigated carbon emissions recognizing UN Secretary General Ban Ki-moon’s exhortation that ‘.. there is no “Plan B” for action as there is no “Planet B’.

This report contributes to the national debate on climate-change mitigation, and the importance of deep decarbonization, by examining three alternative pathways that could reduce Italian CO2 emissions by at least 40% in 2030 and 80% in 2050, compared to 1990. It analyzes the challenges the Italian energy system faces, and possible future technological developments that will need to be pursued.

In this study, three Deep-Decarbonization Pathways are defined for Japan, each meeting the 2050 mitigation target, while considering different assumptions regarding the availability of low-carbon technologies. The assessments of these scenarios, using AIM/Enduse and AIM/CGE models, demonstrate that they correspond to realistic transformations and help to identify the conditions for their implementation.

Sector-based CO2 emissions scenarios to 2050 have been generated in order to explore the changes required in Mexico’s energy systems to achieve emissions reductions consistent with the internationally agreed 2°C goal. To develop these scenarios or “pathways,” tools and methodologies were used that are shared between the 16 countries contributing to the Deep-Decarbonization Pathways Project (DDPP).

Decision makers in government and business increasingly need to understand the practical implications of deep reductions in global greenhouse gas (GHG) emissions. This report examines the technical and economic feasibility of such a transition in the United States, evaluating the infrastructure and technology changes required to reduce U.S. GHG emissions in the year 2050 by 80% below 1990 levels, consistent with a global emissions trajectory that limits the anthropogenic increase in earth’s mean surface temperature to less than 2°C.
