On February 2, 2021, the National Academies of Sciences, Engineering and Medicine (NASEM), a private, nonprofit organization of researchers, released a report that provides a road map for achieving a carbon-free economy by 2050.[1] The report estimates that by decarbonizing, the U.S. economy could add 1-2 million jobs and Americans could be paying roughly the same share of income for energy as they do today due to declining costs for technology. The report notes that the road map is "technologically feasible… But it is on the edge of feasibility” and that the plan may not be as feasible politically.

Under the road map, direct federal budget support for clean energy would total $350 billion over 10 years. The report identified 5 technology goals: 1) get to 75% of energy from non-carbon emitting sources by 2030, 2) reduce energy use by new buildings by 50% by 2030, 3)50% of new vehicle sales to be zero-emission vehicles by 2030, 4) increase transmission capacity by about 40% by 2030, and 5) triple federal investment in research development, and demonstration (RD&D) of emerging technologies such as advanced nuclear reactors, carbon capture and sequestration, and hydrogen fuel. The report also proposes policy actions necessary to benefit affected communities, workers hit with job losses, and lower-income families. The report proposes a federal green bank which could provide funding for economic redevelopment. The report also recommends the adoption of a $40 per ton carbon tax, increasing by 5% annually, with rebates to protect lower income customers.
