The US Deep Decarbonization Pathways Project

The U.S. Deep Decarbonization Pathways Project (USDDPP) investigates the concrete requirements of a low-carbon transition in the United States – technology pathways, changes in physical infrastructure, and what policies are actually needed to drive an energy system transformation.

The USDDPP is a member of the Deep Decarbonization Pathways Project (DDPP), a collaboration of research teams from sixteen high-emitting countries, who are developing national decarbonization strategies to limit global warming to 2°C or less. The DDPP emphasizes transparent analysis and practical problem-solving.

USDDP Reports

Policy Implications of Deep Decarbonization in the United States describes how the pace and scale of physical infrastructure changes required to reduce greenhouse gas emissions 80% below 1990 levels by the year 2050 informs the development of coherent, effective energy policy.

Pathways to Deep Decarbonization in the United States assesses the feasibility and cost of a low-carbon transformation. It describes four different technology pathways to a decarbonized energy system by mid-century that meet America’s energy needs and support robust economic growth.

Energy Pathways Model

Coming in 2016, the EnergyPATHWAYS model is a professional, open-source energy and carbon planning tool for use in evaluating long-term, economy-wide greenhouse gas mitigation scenarios. An online version of the tool will be made freely available for use by energy analysts working at national, regional, state, and local levels throughout the world, along with an offline version for use by researchers and developers.

About the USDDPP

Policy Implications of Deep Decarbonization in the United States and EnergyPATHWAYS model development are the products of a research team led by Dr. Jim Williams (Director of the DDPPand Chief Scientist at Energy and Environmental Economics (E3)) along with Ben Haley and Ryan Jones (Senior Consultants, E3). Pathways to Deep Decarbonization in the United States was a joint research effort led by E3 in collaboration with Lawrence Berkeley National Laboratory (LBNL) and Pacific Northwest National Laboratory (PNNL). The project director was Dr. Jim Williams, with Dr. Andrew Jones (LBNL) and Dr. Haewon McJeon (PNNL) conducting GCAM modeling, and Ben Haley conducting EnergyPATHWAYS modeling. Work has been supported by the Sustainable Development Solutions Network and NextGen Climate America.
