The DDPP is a knowledge network comprising 15 Country Research Teams (Australia, Brazil, Canada, China, France, Germany, India, Indonesia, Japan, Mexico, Russia, South Africa, South Korea, United Kingdom, United States), and several Partner Organizations, which develop and share methods, assumptions, and findings related to deep decarbonization. DDPP aims to draw some lessons for the international negotiations leading up to the 21st Conference of the Parties (COP 21) of the UN Framework Convention on Climate Change (UNFCCC), based on emission pathway modeling analyses, by analyzing the technical decarbonization potential, exploring options for deep decarbonization, but also better taking into account existing infrastructure stocks. The 15 DDPs developed by the Country Research Teams share three common pillars of deep decarbonization of national energy systems: energy efficiency and conservation, low-carbon electricity and fuel switching. It shows the possibility to reduce total CO₂-energy emissions by 45% by 2050 with bottom-up analyses by each country team.
