The '''Deep Decarbonization Pathways Project''' ('''DDPP''') is a global consortium formed in October 2013 which researches methods to limit the rise of global temperature due to [[Earth:Global warming|global warming]] to 2{{nnbsp}}°C or less.<ref name="DDPPabout">

 | quote = Dr. Sachs helped start what is perhaps the most serious effort to draw up a detailed road map for the energy transition: the Deep Decarbonization Pathways Project, based in Paris and New York. Over the past couple of years, the effort enlisted teams from 16 countries, which account for the large majority of global emissions, to devise such plans.

</ref>  The focus of the DDPP is on [[Earth:Sustainable energy|sustainable energy]] systems, other sectors of the economy, such as [[Earth:Agriculture|agriculture]] and land-use, are not directly considered.

== Methods ==

Analyses of possible scenarios assume no major changes in culture and rely on existing technology. They assume no major changes in the lifestyles of people in developed countries and do not include possible future technologies such as [[Physics:Fusion power|nuclear fusion]]. Population growth of 1% per year and economic growth of 3% is assumed. Analyses show a need for continued research on energy technologies.<ref name=NYT120115/>

The DDPP rejects an incrementalist approach to climate protection.  Instead, meeting the [[Earth:Climate change mitigation|climate change mitigation]] challenge (as set out in the 2015 Paris Agreement) will require [[Backcasting|backcasting]] to a suitable attractor, such as complete decarbonization.  This method allows short-term policy options to be developed that are consistent with the selected long-term target.  Even so, there are numerous possible deep decarbonization pathways (DDP) for each country and stakeholders and policymakers will need to debate and choose one, building the necessary political consensus as they go.  DDPs can help avoid dead-end investments that reduce emissions in the short-term but obstruct deep decarbonization in the long-term and thereby reduce the risk of becoming [[Stranded asset|stranded]].<ref name="bataille-etal-2016">

In 2016, the project proposed a new conceptual decision framework for deep development pathways (DDP) analysis across its 16 participating countries.  This includes an agenda for the further development of modelling methodologies.  A key motivation is to address the "intertwined goals of transparency, communicability and policy credibility."<ref name="pye-and-bataille-2016">

== Findings ==

DDPP's analyses show that meeting a goal of limiting the rise of global temperature due to 2{{nnbsp}}°C or less is barely possible using existing technology, if it were deployed, however long term plans are not in place to do so.<ref name=NYT120115/>

As of early 2016, the DDPP was composed of energy researchers and institutions across the following economies and covering 74% of global energy-related greenhouse gas emissions: Australia, Brazil, Canada, China, France, Germany, India, Indonesia, Italy, Japan, Mexico, Russia, South Africa, South Korea, the UK and the US.
