Reducing emissions, through a cap-and-trade program or regulations for example, would impose a burden on the economy by lessening the use of fossil fuels and altering patterns of land use. Today CBO released a brief discussing the economic costs of reducing greenhouse-gas emissions in the United States, describing the main determinants of costs, how analysts estimate those costs, and the magnitude of estimated costs. The brief also illustrates the uncertainty surrounding such estimates using studies of a recent legislative proposal, H.R. 2454, the American Clean Energy and Security Act of 2009.
