“The Sustainable Development Solutions Network (SDSN) and the Institute for Sustainable Development and International Relations (IDDRI) co-founded and lead the DDPP. Currently, 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. The 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). It will issue periodic report on deep decarbonization. The DDPP is issuing this interim 2014 report to the UN Secretary-General Ban Ki-moon in support of the Climate Leaders’ Summit at the United Nations on September 23. It presents preliminary findings on technically feasible pathways to deep decarbonization. The complete 2014 DDPP report will be issued in September ahead of the Summit. To further this discussion we invite comments and suggestions for improvement on this interim 2014 report before August 15, 2014, to be sent at [email protected]. In the first half of 2015, the DDPP will issue a more comprehensive report to the French Government, host of the 21st Conference of the Parties (COP 21) of the United Nations Framework Convention on Climate Change (UNFCCC).”
