Mr. Cohen (for himself, Ms. Castor of Florida, Ms. Dean of
Pennsylvania, Mr. Goldman of New York, Ms. Jayapal, Ms. Morrison, Ms.
Norton, and Mr. Quigley) introduced the following bill; which was
referred to the Committee on Energy and Commerce
_______________________________________________________________________
A BILL
To amend the Clean Air Act to establish requirements on the collection
of electricity consumption data and emissions standards for servers and
other computing equipment used for cryptocurrency mining, and for other
purposes.
Be it enacted by the Senate and House of Representatives of the
United States of America in Congress assembled,
SECTION 1. SHORT TITLE.
This Act may be cited as the ``Clean Cloud Act of 2025''.
SEC. 2. FINDINGS.
Congress finds that--
(1) data centers are estimated to account for
approximately--
(A) 1 percent of global electricity demand; and
(B) 4 percent of United States electricity use;
(2) the growing demand for information technology and
artificial intelligence will increase the demand for data
center services;
(3) the global COVID-19 pandemic has further increased the
demand described in paragraph (2) beyond previous projections;
(4) data centers are projected to account for up to 12
percent of United States electricity use by 2028;
(5) future electricity consumption and efficiency trends
will be determined by management practices, demand for
services, and adoption of efficient technologies;
(6) proof-of-work cryptocurrencies are by design an
increasingly energy intensive process;
(7) studies estimate that--
(A) the total network hashrate for Bitcoin mining
in the United States has increased 739 percent between
September 2020 and January 2022; and
(B) as of July 2021, the greatest share of Bitcoin
mining occurs in the United States;
(8) there is a lack of transparency regarding the energy
sources used to power domestic cryptomining and many data
center operations; and
(9) retired and retiring fossil fuel plants in the United
States are being brought back online to power cryptomining
facilities and data centers, which increases associated carbon
emissions.
SEC. 3. EMISSIONS FROM POWER CONSUMPTION OF DATA CENTERS AND
CRYPTOMINING FACILITIES.
Part A of title I of the Clean Air Act (42 U.S.C. 7401 et seq.) is

purchase agreement or other contractual
mechanism;
``(ii) the electricity is generated--
``(I) in the same calendar year as
the electricity is consumed by the
covered facility, in the case of
electricity that is generated before

``(iii)(I) the electricity generation asset
that produced the electricity is electrically
interconnected to a balancing authority located
in the same region as the covered facility; or
``(II) the owner of the electricity
generation asset can demonstrate that the power
produced by the electricity generation asset is
physically delivered to the covered facility,
as determined by the Administrator, in
coordination with the Secretary of Energy; and

``(5) Electricity consumed from assets behind the meter.--
For purposes of collecting the information described in
paragraph (2)(G) with respect to a covered facility--
``(A) the Administrator, in conjunction with the
Administrator of the Energy Information Administration,

kilowatt-hour, of the electricity generation
asset is higher than the greenhouse gas
emissions intensity of the electric utilities
that serve the covered facility, based on the
average resource mix of those electric
utilities.
``(6) Greenhouse gas emissions intensity.--Based on the
information collected under paragraph (1), for each covered
