MOST RECENT DEVELOPMENTS
On February 16, 2005, the Kyoto Protocol to the United Nations Framework
Convention on Climate Change (UNFCCC) entered into force, committing those nations that
have ratified it to specified mandatory reductions in greenhouse gas emissions below 1990
levels. The 160 nations that had ratified the Protocol as of February 6, 2006, now represent
61.6% of the 1990 emissions baseline among developed nations (55% must be accounted for
by industrialized countries that have ratified in order for the Protocol to enter into force).
The United States is a party to the UNFCCC, but not to the Kyoto Protocol. The first
meeting of the Kyoto Protocol parties occurred November 28-December 9, 2005, in a joint
meeting with the 11th Conference of the Parties (COP-11) of the UNFCCC.
On June 22, 2005, the U.S. Senate passed a “Sense of the Senate” resolution as an
amendment to H.R. 6, the Energy Policy Act of 2005, which included findings that
greenhouse gases are accumulating in the atmosphere, causing average temperatures to rise,
and there is “growing scientific consensus that human activity is a substantial cause of
greenhouse gas accumulation in the atmosphere.” It stated the sense of the Senate “that
Congress should enact a comprehensive and effective national program of mandatory,
market-based limits and incentives on emissions of greenhouse gases that slow, stop, and
reverse the growth of such emissions....,” while not significantly harming the U.S. economy,
and in a way that will encourage comparable action by other nations. This resolution was
not included in the final energy bill by the conference committee.
BACKGROUND AND ANALYSIS
Global Climate Change Science
A large number of scientists believe that human activities, which have increased
atmospheric concentrations of carbon dioxide (CO ) by 35% from preindustrial values of 280
2
parts per million (ppm) to 378 ppm over the past 150 years, are leading to an increase in
global average temperatures. Global temperatures have already risen 0.6oC (0.9oF) in the last
100 years, and, according to model projections, might rise anywhere from as little as 1.8oC
to as much as 7.1oC (2.7oF to 10.7oF) over the next 100 years. However, the science of
“global warming” is not without challengers, who argue that scientific proof is incomplete
or contradictory, and that there remain many uncertainties about the nature and direction of
Earth’s climate. Nevertheless, there is significant concern that human activities, such as the
burning of fossil fuels, industrial production, deforestation, and certain land-use practices are
increasing atmospheric concentrations of carbon dioxide (CO ) that, along with increasing
2
concentrations of other trace gases such as methane (CH ), nitrous oxide (N O), hydrofluoro-
4
2
carbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF ), may be leading to
6
changes in the chemical composition and physical dynamics of Earth’s atmosphere, including
how heat/energy is distributed between the land, ocean, atmosphere and space.
Greenhouse Gases: Sources and Trends
Scientists have found that the four most important variable greenhouse gases, whose
atmospheric concentrations can be influenced by human activities, are carbon dioxide (CO ),
2
CRS-1

IB89005
03-21-06
methane (CH ), nitrous oxide (N O), and chlorofluorocarbons (CFCs). Historically, CO has
4
2
2
been the most important, but those other atmospheric trace gases are also radiatively active,
in that they can affect Earth’s heat budget and thereby contribute to a greenhouse warming
of the lower atmosphere.
The amount of carbon cycling from naturally occurring processes each year through the
biosphere as CO is enormous — some 800 billion tons. Ice cores and other proxy climate
2
data, which also indicate CO concentrations in the atmosphere, have shown, in general, a
2
relatively stable global climate, at least over the past 10,000 years. As such, many scientists
suggest that the amount of CO generated by natural processes is about equal to the amounts
2
absorbed and sequestered by natural processes. However, human activity since the Industrial
Revolution (c.a. 1850), and primarily in the form of burning fossil fuels, is now generating
some additional 24 billion tons of CO per year. Available evidence shows that about half
2
this amount is absorbed by natural processes on land and in the ocean, and that atmospheric
concentrations of CO are currently about 35% higher at 378 parts per million (ppm) than
2
they were some 150 years ago at 280 ppm. Some scientists believe that a large amount of
CO may be stored in northern latitude soils and in temperate and tropical forests, suggesting
2
a greater importance of the role of natural resources management and land-use practices in
these regions, including burning of biomass and deforestation. Scientists estimate that
anthropogenic emissions of CO alone may account for as much as a 60% increase in global
2
mean temperatures of 0.9oF, since 1850.
The combined radiative forcing from the other trace gases is approximately equal to that
of CO and, collectively, they are projected to contribute about as much to potential global
2
warming over the next 60 years as CO . Some of the halogenated compounds, while present
2
in the atmosphere at very low concentrations, are of considerable interest because of their
high global warming potentials (GWPs) and long atmospheric residence times. Methane
concentrations had been rising from a preindustrial value of around 700 parts per billion
(ppb) up to the mid-1990s, when they began to level off to a present value of about 1,766
ppb, representing a 152% increase. Nitrous oxide concentrations have been rising from a
preindustrial value of around 270 parts per billion (ppb) up to a present value of about 317
ppb, representing a 17% increase. The atmospheric concentrations of the chlorofluorocarbons
CFC-11, at 268 parts per trillion (ppt), and CFC 113, at 84 ppt, have been on the decline in
recent years in response to the Montreal Protocol of the late 1980’s. The concentration of
CFC-12 at 533 ppt is also anticipated to decline, but the decline is expected to be delayed due
to (1) a longer atmospheric lifetime than CFC-11 or CFC-113, (2) its use in long-lasting
appliances such as home refrigerators, and, possibly, (3) particularly extensive stockpiling
at the global scale, due to a perceived lack of suitable replacement at the time production
decreases were being mandated. The Kyoto Protocol on Climate Change also regulates three
other trace gases: hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur
hexafluoride (SF ), whose limited concentrations in the atmosphere are anticipated to grow
6
over the long term. Sulfate aerosols, a byproduct of air pollution, and other natural
phenomena are also viewed as important for their transient and regional “climate cooling”
effects in Earth’s atmosphere.
On a related note, NASA scientist James Hansen has suggested that climate change
benefits could be achieved through near-term regulation of non-CO greenhouse gases. He
2
proposed that reducing emissions of halocarbons (refrigerants), methane, nitrogen oxides,
and carbon-black aerosols (soot) could have the effect of reducing ozone in the troposphere,
CRS-2

IB89005

which itself is a greenhouse gas. Non-CO greenhouse gases have relatively short
2
atmospheric lifetimes compared with CO ; however, most have a much larger global
2
warming potential (gwp). This would suggest that controlling emissions of these greenhouse
gases could reduce the rate and overall amount of potential climate warming from
greenhouse gases, leaving only that projected from long-term CO emissions whose full
2
effects might not be realized for another 75-100 years. Nevertheless, Hansen emphasized
that any actions to reduce emissions of these gases would need to be taken concomitantly
with long-term strategies to reduce CO . Hansen also noted that modest gains from reducing
2
CO and non-CO emissions in the near term could be achieved primarily through cleaner
2
2
energy production.
Climate System Response
The most recent runs of state-of-the-art computer models of the Earth’s climate (general
circulation models — GCMs) have projected a globally averaged warming ranging from
almost 3 to10.7degrees F over the next 100 years, if greenhouse gases continue to accumulate
in the atmosphere at the current rate. Many climate scientists believe that such a warming
could shift temperature zones, rainfall patterns, and agricultural belts and, under certain
scenarios, cause sea level to rise. With regard to sea level rise, over the last 100 years, the
global sea level has risen by about 10 to 25 centimeters (4 to 10 inches). It is likely that much
of the rise in sea level has been related to the concurrent rise in global temperature over the
last 100 years. On this time scale, the warming and the consequent thermal expansion of the
world ocean may account for about 0.8 to 3 inches of the observed sea level rise, while the
observed retreat of glaciers and ice caps may account for about 0.8 to 2 inches. Other factors
are more difficult to quantify, including isostatic effects associated with rising or subsiding
coastlines, neotectonics, and sedimentation. The rate of observed sea level rise suggests a net
positive contribution from the huge ice sheets of Greenland and Antarctica, but observations
of the ice sheets do not yet allow meaningful quantitative estimates of their separate
contributions. The ice sheets remain a major source of uncertainty in accounting for past
changes in sea level because of insufficient data about them over the last 100 years. Taking
into account the ranges in the estimate of climate sensitivity and ice melt parameters, and the
full set of greenhouse gas emissions scenarios, the models project an increase in global mean
sea level of between 5 and 37 inches by the year 2100. In addition, because of the thermal
inertia of the oceans, sea level could continue to rise for many centuries beyond 2100 even
if concentrations of greenhouse gases were stabilized at that time. Some climate scientists
further project that global warming could have far-reaching effects — some positive, some
negative, depending how it may be experienced in a given region — on natural resources;
ecosystems; food and fiber production; energy supply, use, and distribution; transportation;
land use; water supply and control; and human health.
Skeptics of the global warming theory have called into question the reliability of the
computer climate models and their output used to make projections of future warming that
supported Kyoto Protocol negotiations. They also challenge some scientists’ assertions that
recent episodic weather events may seem more extreme in nature, and that this may be
indicative of long-term climate change.
Evidence of natural variability of climate is large enough that even the record-setting
warmth at the end of the 20th century has made it difficult for many climate scientists to state
beyond a reasonable doubt that weather extremes experienced over the past two decades are
CRS-3

attributable to “global warming,” at least at the present time. However, the warming trend
at the surface appears to be continuing. In some cases, causal relationships between seasonal
and inter annual climate variability and present-day severe weather events are beginning to
be recognized and even predicted, owing to an improved ability to observe such phenomena
as El Nino and La Nina, the North Atlantic Oscillation (NAO), and the Pacific Decadal
Oscillation (PDO). That notwithstanding, singular extreme weather events have focused
public, academic, and government attention on possible outcomes of potential long-term
climate change and a need for a better understanding of regional climates on decadal to
century time scales.

National Oceanic and Atmospheric Administration’s (NOAA) researchers reported that
the 12 warmest years (globally averaged) since historical records have been kept occurred
in the past two decades, with 1990 and 1998 among the warmest. Those records reveal that
the year 2004 was the fourth warmest worldwide since records began. At least some of this
warming, they concluded, is human-induced. On the other hand, satellite instruments —
which, through indirect methods, measure the average temperature of the atmosphere in a
deep column above the surface — are hard pressed to demonstrate any positive trends over
the past 20-year period.
A report issued by the U.S. National Research Council’s Board on Atmospheric
Sciences and Climate, Reconciling Observations of Global Temperature Change (2000),
attempted to resolve apparent disparities between temperature data measured at the surface
and those from satellites. Those scientists who question the surface temperature record state
that such disparate trends invalidate the output of general circulation models (GCMs), many
of which demonstrate homogenous warming throughout all the levels of the Earth’s
atmosphere. Panel scientists concluded that there may be a systematic disconnect between
the upper and near surface atmosphere and cited physical processes that may have an unique
impact on the upper atmosphere that are not currently accounted for in GCMs. In addition,
they acknowledged that only long-term, systematic monitoring of the upper atmosphere
could resolve the differences in temperature trends. Scientific work continues in the opposing
communities and among government and university modeling centers, accompanied by
analysis of weather balloon and radiosonde data and re-analysis of surface temperature and
satellite data sets, with the prospect of advancing resolution of this pivotal issue.
The Intergovernmental Panel on Climate Change (IPCC), jointly established in 1988
by the United Nations World Meteorological Organization (WMO) and the United Nations
Environment Program (UNEP), reported in its Second Assessment (1996) that “... [such] a
change is unlikely to be entirely natural in origin ... [and that] the balance of evidence, from
changes in global mean surface air temperature and from changes in geographical, seasonal,
and vertical patterns of atmospheric temperature, suggests a discernible human influence on
global climate.” Issuing an updated conclusion in January 2001, the Intergovernmental Panel
in its Third Assessment (2001), reported that a firmer association between human activities
and climate seemed to have emerged, stating that “... in the light of new evidence and
improved understanding, and taking into account the remaining uncertainties, most of the
observed warming over the last 50 years is likely to have been due to the increase in
greenhouse gas concentrations.” That was news, because reservations about the source of
the past century’s warming and whether it bore a human fingerprint are often cited in policy
debates, usually in support of deferring actions aimed at mitigating possible global warming.
In addition, the IPCC reported a higher range of potential warming — roughly between 2.7
and just under 11 degrees Fahrenheit over the next 100 years.

In the United States, the national assessment report Climate Change Impacts on the
United States: The Potential Consequences of Climate Variability and Change (2000),
published and released under the auspices of the U.S. Global Research Program, received
criticism from many of those involved in its review. Critics claimed that many of the model-
projected impacts of possible future climate changes were overstated and unsubstantiated.
The National Assessment Synthesis Team (NAST), with overall authority for the report,
countered that much of the criticism it had received did not take into account the time scales
upon which the report was based; the report targeted the effects of climate toward the middle
of this century to the end of the next. Also, seemingly contradictory outcomes were
produced by the two climate models selected for making the climate projections, casting
some lingering doubt on the overall value and utility of the results for decision makers at the
local, regional, and national levels. Various regional and resource-focused assessments are
now available at the USGCRP website, [http://www.usgcrp.gov/usgcrp/nacc/default.htm].
A final synthesis report by the NAST, of the same title and consisting of an overview of all
of the regional and sectoral studies, was released in December 2000.
On June 6, 2001, a Committee on the Science of Climate Change of the U.S. National
Research Council (NRC) released a report, Climate Change Science: An Analysis of Some
Key Questions
, stating that global warming could well have serious societal and ecological
impacts by the end of this century. Commissioned by the Bush White House and prepared
by 11 of the nation’s leading climate scientists, the report summarized the current state of
knowledge on climate change and confirmed that the climatic changes observed during the
past several decades were most likely due to human activities. The committee members
warned, however, that they could not rule out the possibility that the climate’s natural
variability could be responsible for a significant portion of that trend. The authors agreed that
human-induced warming and sea level rise were expected to continue through the 21st
century and beyond, but they emphasized that current predictions of the magnitude and rate
of future warming “should be regarded as tentative and subject to future adjustments (either
upward or downward).”
The NRC report generally concurred with the latest conclusions of the
Intergovernmental Panel on Climate Change, which found that the Earth warmed by about
1 degree Fahrenheit during the 20th century, and that most of the warming of the past 50
years was probably due to increases in greenhouse gas concentrations in the atmosphere. The
full report, Climate Change Science: An Analysis of Some Key Questions, is available online
at [http://fermat.nap.edu/html/climatechange/] or may be downloaded as a PDF file at
[http://www.nap.edu/catalog.php?record_id=10139].
President Bush made a speech on global climate change from the Rose Garden on June
11, 2001, following release of that NRC Key Questions report and completion of a cabinet-
level review of climate change options. In that speech, timed just before his trip to Europe
to meet with leaders there, the President acknowledged that the world has warmed and that
greenhouse gases have increased, largely due to human activity, but emphasized that the
magnitude and rate of future warming are unknown.
The Policy Context
Since the conclusion of the United Nations Framework Convention on Climate Change
in 1992, U.S. climate policy has been evolving through several different stages, first under
CRS-5

the Clinton Administration, and then under a very different approach under the Bush
Administration. This history is reviewed briefly below. (For more information on U.S.
Climate Policy and how it has developed, see CRS Report RL31931, Climate Change:
Federal Laws and Policies Related to Greenhouse Gas Reductions.
)
Clinton Administration Policies. Taking office the year after the UNFCCC was
completed, the Clinton Administration presided over early U.S. efforts to deal internationally
with climate change, and to participate in formulation of the Kyoto Protocol to the UNFCCC.
On October 19, 1993, President Clinton released his Climate Change Action Plan (CCAP),
which proposed voluntary domestic measures to attain greenhouse gas emissions
stabilization as outlined by the UNFCCC, to stabilize U.S. emissions at 1990 levels by the
year 2000. The CCAP called for comprehensive voluntary measures by industry, utilities and
other large-scale energy users. CCAP stressed energy-efficiency upgrades through new
building codes in residential and commercial sectors, and other improvements in energy
generating or using technologies. Large-scale tree planting and forest reserves were
encouraged to enhance sequestration of carbon dioxide and to conserve energy. Other
aspects of the plan addressed mitigation of greenhouse gases other than CO . The CCAP
2
avoided mandatory command and control measures.
On November 12, 1998, President Clinton instructed a representative to sign the Kyoto
Protocol to “lock in” U.S. interests achieved during negotiations. This act drew protest by
some in Congress. Some Members claimed Clinton action was in violation of the June 1997
Byrd/Hagel Resolution (S.Res.98) that required an economic analysis of legally binding
emission reductions on the United States, as well as binding obligations for all UNFCCC
parties, including developing countries. The President announced he would continue to
pursue”meaningful” commitments from key developing countries before he would send the
treaty to the Senate for advice and consent.
The Clinton Administration released an economic analysis in July 1998, prepared by
the Council of Economic Advisors, that concluded that with emissions trading among the
Annex B/Annex I countries, and participation of key developing countries in the “Clean
Development Mechanism” — which grants the latter business-as-usual emissions rates
through 2012 — the costs of implementing the Kyoto Protocol could be reduced as much as
60% from many estimates. Other economic analyses, however, prepared by the
Congressional Budget Office and the DOE Energy Information Administration (EIA), and
others, projected a potentially large declines in GDP from implementing the Protocol.
On November 11, 2000, President Clinton issued a statement on “Meeting the
Challenge of Global Warming” in response to the results of the report Climate Change
Impacts on the United States: The Potential Consequences of Climate Variability and
Change
(available at [http://www.usgcrp.gov/usgcrp/nacc/default.htm]). In his statement,
President Clinton said he would promulgate new regulations for U.S. electric power plants,
imposing emissions caps on sulphur, nitrogen oxides, mercury, and CO . He also called for
2
establishment of a domestic emissions trading program and promised a continued U.S.
leadership role in climate change to set an example for other industrialized countries.
President Clinton announced he would take such steps as necessary to keep the United States
on target for meeting Kyoto Protocol goals, if certain concessions were made regarding
international adoption of flexible mechanisms such as emissions trading, the clean
development mechanism (CDM), credit for carbon sinks, and accountable, legally-binding,
compliance mechanisms.

Bush Administration Policies. Soon after taking office, the Bush Administration
had asked for a delay in resumption of the collapsed COP-6 negotiations (see COP-6
discussion below), in order to allow time for consideration of its approach and policies.
Talks were accordingly scheduled for the second half of July. However, in late March 2001,
the Bush Administration rejected the Kyoto Protocol — causing widespread concern among
the EU nations — citing lack of developing country participation and possible harm to the
U.S. economy. This followed extensive press attention to, first, statements by the EPA
Administrator that — pursuant to a campaign statement by then-candidate George W. Bush
— carbon dioxide would be included in a multi-pollutant regulatory effort; and then a
repudiation of that position and clarification by President Bush and Administration
spokespersons that carbon dioxide would not be regulated.
President Bush made a policy statement in mid-June 2001, resulting from a continuing
cabinet-level review of climate change options, in which he outlined the U.S. approach as
rejecting the Kyoto Protocol and favoring voluntary actions, increased scientific research,
and market mechanisms. This preceded his trip to Europe for meetings with European heads
of state, which ended with statements that Europe and the United States “agree to disagree”
on climate change approaches. President Bush also outlined a Climate Change Research
Initiative (CCRI) and a National Climate Change Technology Initiative (NCCTI), along with
a new Cabinet-level Committee on Climate Change Science and Technology Integration to
oversee their implementation. The CCRI focuses on short-term, policy-relevant objectives
of climate change science. A previously established U.S. Global Change Research Program
(USGCRP) supports long-term, fundamental, scientific research objectives.
Both the new CCRI and the existing USGCRP were combined for the first time into the
Climate Change Science Program (CCSP) in the FY2004 budget. The FY2007 budget
requests a total spending level of $1.717 billion for research managed by the CCSP, which
is $4 million (+0.2%) above the FY2006 funding estimate of $1.713 billion. Included in the
$1.717 billion CCSP funds are $200 million for the CCRI. While funding for the embedded
CCRI experienced growth over two fiscal years from FY2003 to FY2005, the FY2007
funding request for CCRI at $200 million is level with the FY2006 funding estimate of $200
million. That leaves the FY2007 funding request for the embedded USGCRP standing at
$1.517 billion, which is $4 million (+0.3%) above the FY2006 funding estimate of $1.513
billion. Some $3.069 billion is in the FY2006 funding profile for technology research and
development in the NCCTI/Climate Change Technology Program(CCTP), an amount $79
million (+2.6%) above the FY2005 funding level of $2.99 billion; however, no details about
funding or level of effort for the NCCTI or CCTP were included in the President’s FY2007
budget request, except to say that the Climate Change Technology Program Office is in the
process of addressing the nearly 300 comments received on its Draft Strategic Plan, in
advance of publishing a final Strategic Plan on Climate Change Technology later on in 2006.
Two issues of concern for Congress are the extent to which spending for the CCRI and
CCTP represents new money versus how much is attributable to the reclassification of
ongoing research and technology programs, and whether reduced funding in some cases, or
virtual level funding in most other cases, might be deemed necessary or sufficient to
accomplish the work of the CCSP and the CCTP. The Administration released a Climate
Change Science Program Strategic Plan
on July 24, 2003. The plan included five major
research goals and dozens of specific research targets as well as 23 written synthesis and
assessment products with deadlines. The plan did not give budget details. The National
CRS-7

Research Council of the National Academy of Sciences conducted an independent review
of the Strategic Plan and in April 2004 published its overall assessment in a 51-page report,

In June 2001, the Europeans announced their intentions to proceed with ratification of
the Kyoto Protocol, while President Bush indicated the United States would continue to
participate in negotiations of the UNFCCC parties in order to pursue its own objectives, but
would not participate directly in Kyoto Protocol negotiations. When talks resumed among
UNFCCC parties at “COP-6 resumed” in mid-July in Bonn, Germany, and continued in the
fall of 2001 in Marrakech, Morocco at COP-7, the United States delegation did not make
new proposals and declined to participate in negotiations on issues of the Kyoto Protocol.
Agreement among the other parties was found on the remaining Protocol issues at COP-7,
and they announced that they would seek ratification of the Kyoto Protocol, and its entry into
force — even without the participation of the United States.
On February 14, 2002, apparently concluding the cabinet-level review of climate change
underway since early 2001, President Bush announced a U.S. policy for climate change: a
“new approach for meeting the long-term challenge of climate change.” The centerpiece of
this announcement was the plan to reduce greenhouse gas intensity of the U.S. economy by
18% over the next 10 years. Greenhouse gas intensity measures the ratio of greenhouse gas
emissions to economic output, and has been declining in the United States over the past
several years. The Administration stated that the goal, to be met through voluntary action,
is to achieve efficiency improvements that would reduce the 183 metric tons of emissions
per million dollars of gross domestic product (GDP) to 151 in 2012. The plan noted that “if,
in 2012, we find that we are not on track toward meeting our goal, and sound science justifies
further policy action, the United States will respond with additional measures that may
include a broad, market-based program” and other incentives and voluntary measures to
accelerate technology development.
In addition, the policy directed the Secretary of Energy in consultation with other key
agencies, to “substantially improve the emission reduction registry” to upgrade the voluntary
emission reduction program under section 1605(b) of the 1992 Energy Policy Act, to bring
about enhanced measurement accuracy, reliability, and verifiability. Other measures
included providing for protected, transferable emission reduction credits, increased funding
of $700 million in total climate-related spending, and a new management structure to
coordinate climate change and technology research. Domestic policies such as tax incentives
for renewable energy and new technology, development of fuel-efficient vehicles and cleaner

fuels, and carbon sequestration were also proposed, along with several international bilateral
initiatives and relatively modest increases in foreign assistance.
Some observers praised the plan for taking a practical, conservative approach to
government action and for relying on voluntary measures. Critics observed that voluntary
approaches by themselves have not historically often been effective, and noted that the
reductions in energy intensity are very little different from current trends and would allow
for significant increases in overall greenhouse gas emissions rather than reductions.
Continuing to encourage voluntary action rather than mandatory requirements, the
Administration detailed on February 12, 2003, a set of voluntary agreements by various
industry groups under an umbrella initiative titled Climate VISION (Voluntary, Innovative
Sector Initiatives: Opportunities Now). These initiatives by sectoral groups involve actions
to reduce greenhouse gas emissions and improve energy efficiency. (For a fuller description,
see [http://www.whitehouse.gov/news/releases/2002/02/climatechange.html].)
International Action
The United States was involved in negotiations and international scientific research on
climate change prior to ratifying the 1992 U.N. Framework Convention on Climate Change
(UNFCCC). This included passage of a National Climate Program Act of 1978 (P.L. 95-
367). These activities are discussed in CRS Report RL30522, Global Climate Change: A
Survey of Scientific Research and Policy Reports
, in which early aspects of the scientific
debate and a chronology of U.S. government involvement in climate change policy prior to
1992 are featured.
U.N. Framework Convention on Climate Change (UNFCCC)
The United Nations Framework Convention on Climate Change (UNFCCC) was
opened for signature at the 1992 United Nations Conference on Environment and
Development (UNCED) conference in Rio de Janeiro (known by its popular title, the Earth
Summit). On June 12, 1992, the United States, along with 153 other nations, signed the
UNFCCC, that upon ratification committed signatories’ governments to a voluntary “non-
binding aim” to reduce atmospheric concentrations of greenhouse gases with the goal of
“preventing dangerous anthropogenic interference with Earth’s climate system.” These
actions were aimed primarily at industrialized countries, with the intention of stabilizing their
emissions of greenhouse gases at 1990 levels by the year 2000; and other responsibilities
would be incumbent upon all UNFCCC parties. The parties agreed in general that they would
recognize “common but differentiated responsibilities,” with greater responsibility for
reducing greenhouse gas emissions in the near term on the part of developed/industrialized
countries, which were listed and identified in Annex I of the UNFCCC and thereafter
referred to as “Annex I” countries.
On September 8, 1992, then-President Bush transmitted the UNFCCC for advice and
consent of the U.S. Senate to ratification. The Foreign Relations Committee approved the
treaty and reported it (Senate Exec. Rept. 102-55) October 1, 1992. The Senate consented
to ratification on October 7, 1992, with a two-thirds majority vote. President Bush signed
the instrument of ratification October 13, 1992, and deposited it with the U.N. Secretary
CRS-9

IB89005

General. According to terms of the UNFCCC, having received over 50 countries’
instruments of ratification, it entered into force March 24, 1994.
Since the UNFCCC entered into force, the parties have been meeting annually in
conferences of the parties (COP) to assess progress in dealing with climate change, and
beginning in the mid-1990’s, to negotiate the Kyoto Protocol to establish legally binding
obligations for developed countries to reduce their greenhouse gas emissions. After
completion of the Protocol in 1997, COP meetings focused on formulating the operational
rules that would prevail as nations attempted to meet their obligations to reduce emissions.
These rules were essentially agreed upon at COP-7 (see below) in 2001. As of February 16,
2005, the Kyoto Protocol entered into force. At that time, 141 nations had ratified it,
including 35 of the 38 Annex B industrialized countries. Those Annex B parties to the
UNFCCC that have ratified the Kyoto Protocol continue to express hope that the United
States will re-engage in international efforts to reduce greenhouse gas emissions. As of
February 6, 2006, nations that have ratified or accepted the Kyoto Protocol number 160.
COP-1, The Berlin Mandate
The UNFCCC Conference of Parties met for the first time in Berlin, Germany in the
spring of 1995, and voiced concerns about the adequacy of countries’ abilities to meet
commitments under the Convention. These were expressed in a U.N. ministerial declaration
known as the “Berlin Mandate,” which established a two-year Analytical and Assessment
Phase (AAP), to negotiate a “comprehensive menu of actions” for countries to pick from and
choose future options to address climate change which for them, individually, made the best
economic and environmental sense. The Berlin Mandate exempted non-Annex I countries
from additional binding obligations, in keeping with the principle of “common but
differentiated responsibilities” established in the UNFCCC — even though, collectively, the
larger, newly industrializing countries were expected to be the world’s largest emitters of
greenhouse gas emissions 15 years hence.
COP-2, Geneva, Switzerland
The Second Conference of Parties to the UNFCCC (COP-2) met in July 1996 in
Geneva, Switzerland. Its Ministerial Declaration was adopted July 18, 1996, and reflected
a U.S. position statement presented by Timothy Wirth, former Under Secretary for Global
Affairs for the U.S. State Department at that meeting, which (1) accepted the scientific
findings on climate change proffered by the Intergovernmental Panel on Climate Change
(IPCC) in its second assessment (1995); (2) rejected uniform “harmonized policies” in favor
of flexibility; and (3) called for “legally binding mid-term targets.”
COP-3, The Kyoto Protocol on Climate Change
The Kyoto Protocol to the United Nations Framework Convention on Climate Change
was adopted by COP-3, in December 1997 in Kyoto, Japan, after intensive — and tense —
negotiations. Most industrialized nations and some central European economies in transition
(all defined as Annex B countries) agreed to legally binding reductions in greenhouse gas
emissions of an average of 6%-8% below 1990 levels between the years 2008-2012, defined
as the first emissions budget period. The United States would be required to reduce its total
CRS-10

IB89005
03-21-06
emissions an average of 7% below 1990 levels. (For more details, see CRS Report
RL30692: Global Climate Change: The Kyoto Protocol.) The Protocol provides that it will
enter into force when it has been ratified by 55 countries, accounting for 55% of developed
country emissions in 1990. In 1997, prior to the completion of the Kyoto Protocol, the U.S.
Senate passed S.Res.98, which urged the President not to agree to a treaty that did not
include binding commitments for developing countries, or that would cause harm to the U.S.
economy. As noted above, although President Clinton did sign the Protocol in 1998, it was
never submitted by the Clinton Administration to the Senate because it would not have met
the conditions of S.Res. 98.
The Clinton Administration initiated funding efforts to address climate change; in the
FY2001 budget request funding was included for a Climate Change Technology Initiative
(CCTI) first introduced in his FY1999 budget. Somewhat reduced funding for the climate
technology initiatives was received in previous years.
COP-4, Buenos Aires
COP-4 took place in Buenos Aires in November 1998. It had been expected that the
remaining issues unresolved in Kyoto would be finalized at this meeting. However, the
complexity and difficulty of finding agreement on these issues proved insurmountable, and
instead the parties adopted a two-year “Plan of Action” to advance efforts and to devise
mechanisms for implementing the Kyoto Protocol, to be completed by 2000.
COP-5, Bonn, Germany
The 5th Conference of Parties to the U.N. Framework Convention on Climate Change
met in Bonn, Germany, between October 25 and November 4, 1998. It was primarily a
technical meeting, and did not reach major conclusions.
COP-6, The Hague, Netherlands
When COP-6 convened November 13-25, 2000, in The Hague, Netherlands, discussions
evolved rapidly into a high-level negotiation over the major political issues. These included
major controversy over the United States’ proposal to allow credit for carbon “sinks” in
forests and agricultural lands, satisfying a major proportion of the U.S. emissions reductions
in this way; disagreements over consequences for non-compliance by countries that did not
meet their emission reduction targets; and difficulties in resolving how developing countries
could obtain financial assistance to deal with adverse effects of climate change and meet their
obligations to plan for measuring and possibly reducing greenhouse gas emissions. In the
final hours of COP-6, despite some compromises agreed between the United States and some
EU countries, notably the United Kingdom, the EU countries as a whole, led by Denmark
and Germany, rejected the compromise positions, and the talks in The Hague collapsed. Jan
Pronk, the President of COP-6, suspended COP-6 without agreement, with the expectation
that negotiations would later resume. It was later announced that the COP-6 meetings
(termed “COP-6 bis”) would be resumed in Bonn, Germany, in the second half of July. The
next regularly scheduled meeting of the parties to the UNFCCC — COP-7 — had been set
for Marrakech, Morocco, in October-November 2001. (For more detailed discussion of
COP-6 issues, see CRS Report RL30692, Global Climate Change: The Kyoto Protocol.)
CRS-11

COP-6 “bis,” Bonn, Germany
When the COP-6 negotiations resumed July 16-27, 2001, in Bonn, Germany, little
progress had been made on resolving the differences that had produced an impasse in The
Hague. However, this meeting took place after President George Bush had become the U.S.
President, and had rejected the Kyoto Protocol in March; as a result the United States
delegation to this meeting declined to participate in the negotiations related to the Protocol,
and chose to act as observers. As the other parties negotiated the key issues, agreement was
reached on most of the major political issues, to the surprise of most observers given the low
level of expectations that preceded the meeting. The agreements included:
(1) Mechanisms — the “flexibility” mechanisms which the United States had strongly
favored as the Protocol was initially put together, including emissions trading; joint
implementation; and the Clean Development Mechanism (CDM), which provides
funding from developed countries for emissions reduction activities in developing
countries, with credit for the donor countries. One of the key elements of this
agreement was that there would be no quantitative limit on the credit a country could
claim from use of these mechanisms, but that domestic action must constitute a
significant element of the efforts of each Annex B country to meet their targets.
(2) Carbon sinks — credit was agreed to for broad activities that absorb carbon from the
atmosphere or store it, including forest and cropland management, and revegetation,
with no overall cap on the amount of credit a country could claim for sinks activities.
In the case of forest management, an Appendix Z establishes country-specific caps for
each Annex I country, for example, a cap of 13 million tons could be credited to Japan
(which represents about 4% of its base-year emissions). For cropland management,
countries could receive credit only for carbon sequestration increases above 1990 levels.
(3) Compliance — final action on compliance procedures and mechanisms that would
address non-compliance with Protocol provisions was deferred to COP-7, but included
broad outlines of consequences for failing to meet emissions targets that would include
a requirement to “make up” shortfalls at 1.3 tons to 1, suspension of the right to sell
credits for surplus emissions reductions; and a required compliance action plan for
those not meeting their targets.
(4) Financing — three new funds were agreed upon to provide assistance for needs
associated with climate change; a least-developed-country fund to support National
Adaptation Programs of Action; and a Kyoto Protocol adaptation fund supported by a
CDM levy and voluntary contributions.
A number of operational details attendant upon these decisions remained to be
negotiated and agreed upon; these were the major issues of the COP-7 meeting that followed.
COP-7, Marrakech, Morocco
At the COP-7 meeting in Marrakech, Morocco October 29-November 10, 2001,
negotiators in effect completed the work of the Buenos Aires Plan of Action, finalizing most
of the operational details and setting the stage for nations to ratify the Protocol. The United
States delegation continued to act as observers, declining to participate in active negotiations.
Other parties continued to express their hope that the United States would re-engage in the
process at some point, but indicated their intention to seek ratification of the requisite
number of countries to bring the Protocol into force (55 countries representing 55% of
developed country emissions of carbon dioxide in 1990). A target date for bringing the
CRS-12

IB89005
03-21-06
Protocol into force was put forward — the August-September 2002 World Summit on
Sustainable Development (WSSD) to be held in Johannesburg, South Africa — but this
target was not met. The main decisions at COP-7 included operational rules for international
emissions trading among parties to the Protocol and for the CDM and joint implementation;
a compliance regime that outlines consequences for failure to meet emissions targets but
defers to the parties to the Protocol after it is in force to decide whether these consequences
are legally binding; accounting procedures for the flexibility mechanisms; and a decision to
consider at COP-8 how to achieve to a review of the adequacy of commitments that might
move toward discussions of future developing country commitments.
COP-8 (New Delhi, India, 2002), COP-9 (Milan, Italy, 2003),
COP-10 (Buenos Aires, 2004)

At these three meetings of the conference of parties to the UNFCCC, attempts were
made to consider next steps after the 2008-2012 commitment period, but these attempts
encountered resistance from developing countries and some other parties. The announced
reluctance of Russia at the Milan COP-9 to undertake ratification of the Kyoto Protocol
called into question whether or when the Protocol might enter into force. Without U.S.
participation, the required 55% of baseline emissions of parties would not be achieved if
Russia did not ratify. However, just before the COP-10 meeting, Russia did ratify the
Protocol on November 18, 2004. Thus the Kyoto Protocol would enter into force 90 days
later, on February 16, 2005. All three of these meetings centered on largely technical issues,
and avoided major substantive declarations; what “next steps” involving developing
countries should be remained a controversial issue, and was not resolved.
COP-11, Montreal, Canada
COP-11 was held in Montreal, Canada, November 28 - December 9, 2005. This was
a concurrent meeting — the 11th meeting of the parties to the UNFCCC, and the first meeting
of the parties (MOP-1) to the Kyoto Protocol. One of the key outcomes of the Kyoto
Protocol MOP was adoption of the “Marrakech Accords,” which outline what the Secretariat
terms the “rule book” for the Protocol. Among other things, it formally launches emissions
trading by providing rules for trading, and outlines the operational rules for the Clean
Development Mechanism and Joint Implementation, both of which provide for credit to
developed countries for projects to reduce emissions or augment sinks in developing or other
eligible countries. Other rules adopted include how emissions are accounted for, guidelines
on data systems needed, rules for a compliance system, and rules governing how absorption
of carbon dioxide by agricultural soils and forests is to be measured. Discussions of “next
steps” were considered under both the Protocol and the Convention. Negotiations under the
Protocol were agreed upon that could lead to new binding commitments for Kyoto Protocol
parties after 2012; and a decision under the Framework Convention was made to open a non-
binding “dialogue on long-term cooperative action,” which could include all parties to the
Convention, including the United States.
Asia Pacific Partnership on Clean Development and Climate
On July 27, 2005, a six-nation partnership was announced at South East Asian Nations
(ASEAN) forum. This is a partnership agreement among six nations — the United States,
Australia, China, India, Japan, and South Korea. The participants described the focus of the
CRS-13

IB89005
03-21-06
partnership as technology development and reduction of greenhouse gas intensity, with
voluntary participation. Representatives of the six nations met in Sydney, Australia, in early
January, and spelled out the purpose and provided a work plan for the partnership in
statements on January 12, 2006. The purposes included to “Create a voluntary, non-legally
binding framework for international cooperation to facilitate the development, diffusion,
deployment, and transfer of existing, emerging and longer-term cost-effective, cleaner, more
efficient technologies and practices among the Partners through concrete and substantial
cooperation so as to achieve practical results.” Eight task forces were established to review
the status of their sectors with regard to clean development and climate, and to identify cost
and performance objectives and realistic goals; they focused on specific sectors: (1) Cleaner
Fossil Energy, (2) Renewable Energy and Distributed Generation, (3) Power Generation and
Transmission, (4) Steel, (5) Aluminum, (6) Cement, (7) Coal Mining, and (8) Buildings and
Construction. The charter for the partnership states: “The partnership will be consistent with
and contribute to our efforts under the UNFCCC and will complement, but not replace, the
Kyoto Protocol.” (More detailed information is available on the State Department website).
Congressional Interest and Activities
Discourse in Congress over the prospect of global warming and what the United States
could or should do about it has yielded, over the last several years, a range of legislative
proposals. Issues dealt with in bills that have been introduced in the 109th Congress include
regulating emissions of carbon dioxide along with emissions of sulfur dioxide, nitrogen
oxides, and mercury in so-called “multi-pollutant” legislation (see CRS Report RL32755,
Air Quality: Multi-Pollutant Legislation in the 109th Congress); greenhouse gas reduction
and carbon dioxide emissions trading systems (see CRS Report RS21581, Climate Change:
Senate Proposals to Reduce Greenhouse Gas Emissions
and CRS Report RS21067, Global
Climate Change: Controlling CO2 Emissions Cost-Limiting Safety Valves
); energy issues
relevant to climate change, especially those associated with encouraging or authorizing
energy efficiency and alternative energy sources (see CRS Issue Brief IB10041, Renewable
Energy: Tax Credit, Budget, and Electricity Production Issues
and CRS Issue Brief IB10020,
Energy Efficiency: Budget, Oil Conservation, and Electricity Conservation Issues); carbon
sequestration technologies and methodologies; federal and national research concerning the
prospect of abrupt climate change, climate change impacts, and climate system surprises;
federal spending on climate change science programs and climate change technology
programs and, more broadly, on global change research programs; and long-term research
and development programs to develop new technologies to help stabilize greenhouse gas
emissions. (For an overview and comparison of key climate change legislation, see CRS
Report RL32955, Climate Change Legislation in the 109th Congress).
LEGISLATION
P.L. 109-58 (H.R. 6)
The Energy Policy Act of 2005 contains provisions addressing climate change, and a
number of others were debated during consideration of the bill. Title XVI establishes
programs to promote the adoption of technologies to reduce greenhouse gas intensity, similar
to those adopted on the Senate floor in S.Amdt. 817. The House version of H.R. 6 did not
contain climate change or greenhouse gas provisions. Two other climate change amendments
included in the Senate bill as passed were not included in the final version of the bill:
S.Amdt. 866 expressed the sense of the Senate that climate change is a serious concern and
CRS-14

IB89005

that Congress should establish mandatory, market-based limits on greenhouse gas emissions;
and S.Amdt. 826, based largely on S. 1151, would have required mandatory emission
reduction and a cap-and-trade system. H.R. 6 passed the House April 21, 2005. It passed
the Senate June 28, 2005. The conference report, H.Rept. 109-190, was agreed to by the

countries, of which $100 million is to directly promote and deploy energy conservation,
efficiency, renewable and clean technologies, and the balance to measure, monitor, and
reduce greenhouse gas emissions, increase carbon sequestration, and enhance climate change
mitigation and adaptation programs. In addition, a climate change report is required to
describe federal agency obligations and expenditures, domestic and international, for climate
change in FY2005, FY2006, and FY2007 for the U.S. Agency for International
Development. On June 24, 2005, the House Committee on Appropriations reported an
original bill (H.Rept. 109-52). Passed the House on June 28, 2005. On June 30, 2005, the
Senate Committee on Appropriations reported H.R. 3057 with an amendment in the nature
of a substitute and an amendment to the title (S.Rept. 109-96). Passed the Senate on July 20,
