Deep Decarbonization of the United States

Jim Williams, Chief Scientist, Energy and Environmental Economics (E3)

Is it possible to greatly reduce the carbon emissions of the United States and still maintain a vigorous economy? Concern about climate change impacts on the environment and economy is leading to innovation as scientists seek new ways to reduce carbon emissions. Dr. Williams and his team at E3, along with researchers at Berkeley Lab and Pacific Northwest National Laboratory, have completed an assessment of the technical and economic feasibility of reducing U.S. greenhouse gas (GHG) emissions 80 percent below 1990 levels by 2050. Their work is based on a detailed sector-by-sector, region-by-region, year-by-year analysis of the infrastructure changes, technology requirements and costs of a low-carbon transition.

The work was sponsored by the Deep Decarbonization Pathways Project (DDPP), an international collaboration with research teams from the 15 largest GHG emitting nations, who are developing long-term scenarios for decarbonization in their own countries. The DDPP aims to advance the climate dialogue by providing decision makers with a more concrete understanding of what limiting global warming to 2 degrees Celsius would mean for their countries, states and businesses.
