116TH CONGRESS 

2D SESSION H. R. 8174 

To establish a cost of greenhouse gases for carbon dioxide, methane, and 

nitrous oxide to be used by Federal agencies, and for other purposes. 

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 Be it enacted by the Senate and House of Representa2 tives of the United States of America in Congress assembled, 

3 SECTION 1. SHORT TITLE. 

4 This Act may be cited as the ‘‘Carbon Pollution 

5 Transparency Act’’. 

6 SEC. 2. FINDINGS. 

7 Congress finds that—

•HR 8174 IH

1 (1) sound economic and policy analyses require 

2 that the economic benefits of reducing climate 

3 change be considered together with the costs of poli4 cies and measures to reduce greenhouse gas emis5 sions; 

6 (2) climate change, if not addressed, is pro7 jected to inflict substantial damage on the economy 

8 and people of the United States; 

9 (3) according to the Congressional Budget Of10 fice, the Government Accountability Office, and the 

11 Office of Management and Budget, the impacts of 

12 climate change are— 

13 (A) costing United States taxpayers bil14 lions of dollars annually; and 

15 (B) putting pressure on the Federal budg16 et; 

17 (4) the expenditures by the Federal Govern18 ment resulting from the effects of climate change 

19 are projected to increase, and reducing greenhouse 

20 gas emissions presents an opportunity to minimize 

21 those expenditures; 

22 (5) between calendar years 2008 and 2015, the 

23 United States reduced carbon pollution from the en24 ergy sector by nearly 10 percent, while the economy 

25 grew more than 10 percent; 


pbinns on DSKJLVW7X2PROD with BILLS

•HR 8174 IH

1 (6) more than 1,200 companies are taking the 

2 cost of climate change into consideration in business 

3 decisions; 

4 (7) estimates of the costs of greenhouse gases 

5 provide a method and measure, grounded in sci6 entific and economic research, for monetizing— 

7 (A) the costs of greenhouse gas emissions; 

8 and 

9 (B) the benefits of reducing greenhouse 

10 gas emissions; 

11 (8) the National Academies of Sciences, Engi12 neering, and Medicine has provided detailed rec13 ommendations for improving the estimate of the 

14 costs of greenhouse gases for the purpose of regu15 latory analysis; 

16 (9) the reduction of greenhouse gas emissions 

17 by other countries benefits the United States by re18 ducing climate risks to the United States, and the 

19 reduction of greenhouse gas emissions by the United 

20 States benefits other countries; 

21 (10) in light of the global nature of the problem 

22 of greenhouse gas emissions, the interests of the 

23 United States would be maximized if the United 

24 States were to use a calculation method of the cost 

25 of climate pollution that reflects global damages;

•HR 8174 IH

1 (11) due to the nature of climate change risks, 

2 the returns on mitigation may pay off in periods 

3 that would otherwise involve substantial losses; 

4 (12) economic theory and evidence suggests 

5 that, for actions with intergenerational consequences 

6 such as the consequences of climate change, a dis7 count rate approximately equal to or less than the 

8 long-term yield on the debt of the Treasury of the 

9 United States may be appropriate; and 

10 (13) it is imperative that the academic commu11 nity continue research on the cost of greenhouse 

12 gases.

20 method shall be published in the Federal Register 

21 for a period of public comment of not fewer than 90 

22 days and include consultation with industry groups. 

23 (3) EFFECT OF REVISIONS BY WORKING

24 GROUP.—Any revised calculation method of the cost 

25 of carbon dioxide, the cost of methane, or the cost

3 (3) DUTIES.—The Committee shall publish a 

4 report in which the Committee shall— 

5 (A) make a recommendation to the Work6 ing Group regarding whether a revision of the 

7 calculation method is necessary; 

8 (B) if the Committee determines that a re9 vision is necessary, recommend scientific data 

10 and models to be used by the Working Group 

11 in the revision of the calculation method; 

12 (C) provide scientific advice to the Work13 ing Group on the revision; and 

14 (D) provide guidance to the U.S. Global
