Determining how to advance deep decarbonization efforts in the United States is a big picture issue that requires research and analysis on many fronts. Early in 2021, the National Academies of Sciences, Engineering, and Medicine (NASEM) released a Sloan-funded consensus study report, titled Accelerating Decarbonization of the U.S. Energy System,which identifies both key technical and socioeconomic goals to help the U.S. achieve net-zero emissions by 2050 and the near-term federal policies that would set the U.S. on a path to meet those goals. This grant will expand the work of the NASEM committee to further explore the implementation of deep decarbonization interventions in the United States energy system. The first component of this next phase of work is producing a second consensus study on aspects of deep decarbonization not covered in the first report, focusing on issues like environmental justice, the impacts on jobs, and the role of sub-national policies. Second, this grant will help to establish an ongoing Deep Decarbonization Forum to address current and future deep decarbonization issues with a wide range of stakeholders.
