I 116th CONGRESS 2d Session H. R. 8174 IN THE HOUSE OF REPRESENTATIVES September 4, 2020 Mr. McEachin introduced the following bill; which was referred to the Committee on Oversight and Reform , and in addition to the Committee on the Judiciary , for a period to be subsequently determined by the Speaker, in each case for consideration of such provisions as fall within the jurisdiction of the committee concerned A BILL To establish a cost of greenhouse gases for carbon dioxide, methane, and nitrous oxide to be used by Federal agencies, and for other purposes.

1. Short title This Act may be cited as the Carbon Pollution Transparency Act . 2. Findings Congress finds that— (1) sound economic and policy analyses require that the economic benefits of reducing climate change be considered together with the costs of policies and measures to reduce greenhouse gas emissions; (2) climate change, if not addressed, is projected to inflict substantial damage on the economy and people of the United States; (3) according to the Congressional Budget Office, the Government Accountability Office, and the Office of Management and Budget, the impacts of climate change are— (A) costing United States taxpayers billions of dollars annually; and (B) putting pressure on the Federal budget; (4) the expenditures by the Federal Government resulting from the effects of climate change are projected to increase, and reducing greenhouse gas emissions presents an opportunity to minimize those expenditures; (5) between calendar years 2008 and 2015, the United States reduced carbon pollution from the energy sector by nearly 10 percent, while the economy grew more than 10 percent; (6) more than 1,200 companies are taking the cost of climate change into consideration in business decisions; (7) estimates of the costs of greenhouse gases provide a method and measure, grounded in scientific and economic research, for monetizing— (A) the costs of greenhouse gas emissions; and (B) the benefits of reducing greenhouse gas emissions; (8) the National Academies of Sciences, Engineering, and Medicine has provided detailed recommendations for improving the estimate of the costs of greenhouse gases for the purpose of regulatory analysis; (9) the reduction of greenhouse gas emissions by other countries benefits the United States by reducing climate risks to the United States, and the reduction of greenhouse gas emissions by the United States benefits other countries; (10) in light of the global nature of the problem of greenhouse gas emissions, the interests of the United States would be maximized if the United States were to use a calculation method of the cost of climate pollution that reflects global damages; (11) due to the nature of climate change risks, the returns on mitigation may pay off in periods that would otherwise involve substantial losses; (12) economic theory and evidence suggests that, for actions with intergenerational consequences such as the consequences of climate change, a discount rate approximately equal to or less than the long-term yield on the debt of the Treasury of the United States may be appropriate; and (13) it is imperative that the academic community continue research on the cost of greenhouse gases. 3.
