• Overview

    The Deep Decarbonization Pathways Project (DDPP) is a collaborative initiative to understand and show how individual countries can transition to a low-carbon economy and how the world can meet the internationally agreed target of limiting the increase in global mean surface temperature to less than 2 degrees Celsius (°C). Achieving the 2°C limit will require that global net emissions of greenhouse gases (GHG) approach zero by the second half of the century. In turn, this will require a profound transformation of energy systems by mid-century through steep declines in carbon intensity in all sectors of the economy, a transition we call “deep decarbonization.”

  • Organization

    The Sustainable Development Solutions Network (SDSN) and the Institute for Sustainable Development and International Relations (IDDRI) co-founded and lead the DDPP.

    The DDPP comprises 15 Country Research Teams composed of leading researchers and research institutions from countries representing 70% of global GHG emissions and different stages of development: Australia, Brazil, Canada, China, France, Germany, India, Indonesia, Japan, Mexico, Russia, South Africa, South Korea, the UK, and the USA.

  • Approach

    Each Country Research Team develops a national Deep Decarbonization Pathway (DDP) analysis to 2050. The objective of this DDP analysis is to explore each country’s possible transition to a low-carbon economy, taking into account national socio-economic conditions, development aspirations, infrastructure stocks, resource endowments, and other relevant factors.

    The first phase of the DDPP focuses on the technical feasibility of DDPs. The next phases will analyze in further detail how the twin objectives of development and deep decarbonization can be met through integrated approaches; quantify the costs and benefits of deep decarbonization; identify national and international financial requirements; and map out policy frameworks for implementation.

  • Timeline

    The DDPP was launched in Seoul in October 2013 and published the 2014 report Pathways to Deep Decarbonization on September 19, 2014 in support of the United Nations Climate Summit in New York. The DDPP is an ongoing initiative that will issue periodic reports on deep decarbonization.
