DDPP
The Deep Decarbonization Pathways Project (DDPP) is a global collaboration of energy research teams charting practical pathways to deeply reducing greenhouse gas emissions in their own countries. It is predicated on taking seriously what is needed to limit global warming to 2°C or less.
The DDPP framework has been developed and utilized by a consortium led by The Institute for Sustainable Development and International Relations (IDDRI) and the Sustainable Development Solutions Network (SDSN). It currently consists of scientific research teams from leading research institutions in sixteen of the world’s largest greenhouse gas emitting countries.
The initial results of this collaboration are reflected in reports on deep decarbonization pathways for Australia, Brazil, Canada, China, France, Germany, India, Indonesia, Italy, Japan Mexico, Russia, South Africa, South Korea, United Kingdom and United States. In addition, the consortium developed cross-cutting analyses (2014 report, executive summary of the 2015 synthesis report) and open-source tools.
Sponsoring organizations

The Institute for Sustainable Development and International Relations (IDDRI) is a non-profit policy research institute based in Paris. Its objective is to determine and share the keys for analyzing and understanding strategic issues linked to sustainable development from a global perspective. IDDRI helps stakeholders in deliberating on the global governance of major issues of common interest: action to attenuate climate change, to protect biodiversity, to enhance food security and to manage urbanization. IDDRI also takes part in efforts to reframe development pathways.

The Sustainable Development Solutions Network (SDSN) was commissioned by UN Secretary-General Ban Ki-moon to mobilize scientific and technical expertise from academia, civil society, and the private sector to support practical problem solving for sustainable development at local, national, and global scales. The SDSN operates national and regional networks of knowledge institutions, solution-focused thematic groups, and is building SDSNedu, an online university for sustainable development.
