SEC. 2. FINDINGS.
Congress finds as follows:
(1) The United States, like a number of other countries,
should state an objective to stabilize greenhouse gas
concentrations in the atmosphere at a level that would prevent
``dangerous anthropogenic interference'' with the climate
system. The objective should be to reduce its greenhouse gas
emissions by 50 to 52 percent below 2005 levels by 2030.
(2) To achieve this objective, the increase in global mean
surface temperature should not exceed 2C (3.6F) above
preindustrial temperature by 2100 consistent with the Paris
Agreement that entered into force in 2016.
(3) The risks associated with a temperature increase above
2C (3.6F) are grave, including the disintegration of the
Greenland ice sheet, which, if it were to melt completely,
would raise global average sea level by approximately 23 feet,
devastating many of the world's coastal areas and population
centers.
(4) A 2018 report by the Intergovernmental Panel on Climate
Change demonstrated that limiting the temperature increase to
1.5C will result in still harmful, but significantly less
severe outcomes than a 2C increase.
(5) The Intergovernmental Panel on Climate Change projects
that temperatures will rise 1.5C between 2030 and 2052. In
order to limit the temperature increase to 1.5C, global net
anthropogenic carbon dioxide emissions must reach net zero by
2050. The Intergovernmental Panel on Climate Change notes in
their 2023 report that the level of reduction in greenhouse gas
emissions this decade will largely determine whether warming
can be limited to 1.5C or 2C.
(6) A 2023 report by the Intergovernmental Panel on Climate
Change highlights that ``Deep, rapid, and sustained reductions
in greenhouse gas emissions would lead to a discernible
slowdown in global warming within around two decades, and also
to discernible changes in atmospheric composition within a few
years.''.
(7) The 2023 National Climate Assessment, authored by more
than 300 experts and released by the United States Global
Change Research Program, makes clear that the present
unprecedented rises in global temperature are primarily due to
human activities. The changing climate will devastate all
sectors of society and disproportionately harm the most
vulnerable communities.
(8) Serious global warming impacts have already been
observed in the United States and worldwide, including--
(A) increases in heat waves and other extreme
weather events;
(B) rise in sea level, retreat of glaciers and
polar ice;
(C) decline in mountain snowpack, increased drought
(including droughts in the West and South United
States) resulting in damage to our economy and
property;
(D) extreme weather conditions resulting in
wildfires, stronger hurricanes, and polar vortex
occurrences resulting in further damage to property and
our economy;
(E) damage to our environment such as ocean
acidification, extensive coral bleaching, migrations,
and shifts in the yearly cycles of plants and animals;
and
(F) effects on human population, including
population displacement and adverse health effects such
as the spread of infectious diseases and climate-
related conditions such as asthma.
(9) Scientists project that under a midrange estimate of
global warming, by 2050, roughly one-third of animal and plant
species will be committed to extinction.
(10) The Energy Information Administration's International
Energy Outlook report estimates an increase of 20 percent in
global carbon dioxide emissions between 2021 and 2050.
(11) Decisive action is needed to minimize the many dangers
posed by global warming.
(12) The timing of such action is critical, given that
greenhouse gases can persist in the atmosphere for more than a
century.
(13) With less than 5 percent of the world population, the
United States emits approximately 11.5 percent of the world's
total greenhouse gas emissions and must be a leader in
addressing global warming.
(14) The State of California, the 5th largest economy in
the world, has shown that renewable energy standards and
greenhouse gas emissions regulation can reduce greenhouse gas
emissions while fostering significant economic growth.
(15) Existing energy efficiency and clean, renewable energy
technologies can reduce global warming pollution, while saving
consumers money, reducing our dependence on oil, enhancing
national security, cleaning the air, and protecting pristine
places from drilling and mining.

TITLE III--SCIENCE-BASED REDUCTIONS
SEC. 301. NET EMISSIONS REDUCTION TARGETS.
Not later than 1 year after the date of enactment of this Act, the
Administrator of the Environmental Protection Agency (in this title
referred to as the ``Administrator'') shall promulgate annual net
emissions reduction targets for each of calendar years 2030 through
2050, so as to ensure that the quantity of United States net greenhouse
gas emissions--
(1) in 2035, is at least 52 percent below the quantity of
such emissions in 2005; and
(2) in 2050, is zero.
SEC. 302. NATIONAL ACADEMIES REVIEW.
Not later than 5 years after the date of the enactment of this Act,
and every 5 years thereafter, the Administrator shall enter into an
arrangement with the National Academies (or, if the National Academies
decline to enter into such arrangement, another appropriate entity)
under which the National Academies, acting through the National Academy
of Sciences and the National Research Council, will submit a report to
the Administrator and the Congress on the prospects for avoiding
dangerous anthropogenic interference with the climate system and the
progress made to date. Each such report shall--
(1) evaluate whether the net emissions reduction targets
promulgated pursuant to section 301 and the other policies to
reduce United States net greenhouse gas emissions under this
Act, the amendments made by this Act, and other provisions of
law, including the Clean Air Act (42 U.S.C. 7401 et seq.), are
likely to be sufficient to avoid dangerous anthropogenic
interference with the climate system, taking into account the
actions of other nations; and
(2) if the National Academies concludes that such targets
and policies are not likely to be sufficient to avoid dangerous
anthropogenic interference with the climate system--
(A) identify the needed amount of further
reductions in atmospheric greenhouse gas
concentrations; and
(B) recommend additional United States and
international actions to further reduce atmospheric
greenhouse gas concentrations.
SEC. 303. REGULATIONS.
(a) In General.--The Administrator shall--
(1) not later than 7 years after the date of enactment of
this Act, promulgate final regulations to implement the net
emissions reduction targets under section 301; and
(2) not less than every 5 years thereafter--
(A) review such regulations, taking into account
the reports under section 302; and
(B) revise such regulations as necessary to
implement such net emissions reduction targets.
(b) Rulemaking on Recommendations of National Academies.--If any
report under section 302 includes a recommendation under section
302(2)(B) for regulatory action by a Federal department or agency, and
such regulatory action is within the authority of such department or
agency (under law other than this subsection), the head of such
department or agency shall, not later than 2 years after the submission
of such report, finalize a rulemaking--
(1) to carry out such regulatory action; or
(2) to explain the reasons for declining to act.
(c) Additional Regulations.--The regulations promulgated under
subsection (a) may include additional requirements to reduce United
States net greenhouse gas emissions from any source or sector. Any such
regulations that address sources whose greenhouse gas emissions are
regulated pursuant to section 111(d) of the Clean Air Act (42 U.S.C.
7411(d)) shall account for the compliance schedule promulgated pursuant
to such section 111(d). Regulations under this section may include
market-based measures, emissions performance standards, efficiency
performance standards, best management practices, technology-based
requirements, and other forms of requirements.
(d) Relation to Other Authority.--The authority vested by this
title is in addition to the authority to regulate greenhouse gas
emissions pursuant to other provisions of law.
SEC. 304. SAVINGS CLAUSE.
Nothing in this title shall be interpreted to preempt or limit
State actions to address climate change.
