OFFICE TO PROJECT THE NET GREENHOUSE 
GAS EMISSIONS LIKELY TO BE CAUSED BY 
FEDERAL LEGISLATION. 
(a) IN GENERAL.—Not later than 2 years after the 
date of enactment of this Act, the Comptroller General 
of the United States, in coordination with the National 
Academy of Sciences, shall— 
(1) study alternatives for a nonpartisan con-
gressional office or agency— 
(A) to make thorough, science-based pro-
jections on whether the enactment, full funding, 
and implementation of particular Federal legis-
lation are likely to cause a net increase or de-
crease in global greenhouse gas emissions over 
a specified period; and 
(B) to quantify any such projected increase 
or decrease; and 
(2) submit a report to the Congress containing 
the results of such study, including recommenda-
tions.

functions should be vested in one or more existing 
offices or agencies. 
(2) How to ensure the office or agency remains 
nonpartisan and science-focused.

experts, including— 
(A) whether Federal officers and employ-
ees should be detailed to the office or agency 
carrying out the functions described in sub-
section (a)(1); and 
(B) how to involve appropriate experts in 
the analysis of projected greenhouse gas emis-
sions from each of the following: electric power 
generation; transportation; residential, commer-
cial, and industrial fuel use; natural gas and oil 
systems; coal mining and abandoned mines; ag-
riculture; industrial processes; land use, land 
use change, and forestry; and waste manage-
ment. 
(4) Lessons that can be learned from State leg-
islatures that have successfully implemented carbon 
scoring for legislative proposals.
