This report by the Center for American Progress proposes that United States federal agencies and state governments adopt the private-sector practice of proxy carbon pricing when evaluating long-term government decisions and investments, including both direct government action, such as investment in transportation infrastructure, and indirect government action, such as permitting.  The report focuses on energy infrastructure permitting and  how a proxy carbon price could inform government decisions about the US network of pipelines, power plants, transmission lines, and other facilities that transport and generate energy.
