Deep Decarbonization Pathway Project


Restraining global warming to below 2°C requires profound changes that may be difficult to grasp. How can the changes be conceived? How can the specific context and development objectives of each country be taken into account? What policies are needed, both at the local and international levels?

To answer these questions, IDDRI and the Sustainable Development Solutions Network (SDSN) met to form the secretariat of the Deep Decarbonization Pathways Project (DDPP) platform, which to date has been joined by leading research teams from 16 countries that represent over 70% of global greenhouse gas emissions: Australia, Brazil, Canada, China, United States, France, Germany, India, Indonesia, Italy, Japan, Mexico, Republic of Korea, South Africa, United Kingdom and Russia.



The key elements of the working method of this platform include:

  • the deep decarbonization trajectories of each country are developed by local research teams;
  • a common approach is applied (known as backcasting), which uses the 2050 goal as a starting point, then examines the necessary conditions that would enable this target to be reached, as opposed to analysing the extension of current trends;
  • common tools are used to ensure transparency of the working hypotheses, including in sectors and technologies.

The DDPP benefits from collaborations with key partners, who are publishing their national report :
