Global climate change is one of our greatest environmental
challenges.
The overwhelming weight of scientific authority tells us that the build-up
of greenhouse gases in the atmosphere creates dangers -- such as severe
storms and droughts, increases in respiratory and infectious diseases, and
rising sea levels -- that are too serious to ignore.
The Clinton Administration is working at home and abroad to meet the
challenge of climate change. Domestically, we are working on a wide range
of initiatives to reduce greenhouse gas emissions by developing and
deploying energy efficient technologies and spurring the broader use of
renewable energy. Internationally, we are working to secure the
meaningful participation of developing countries in addressing global
warming and to complete the other unfinished business of the Kyoto
Protocol.
THE SCIENCE OF CLIMATE CHANGE
Greenhouse gases trap heat from the sun. These gases warm the Earth's
surface by an estimated 60° Fahrenheit (F), sustaining our existence on
the planet. However, the burning of fossil fuels and deforestation have
increased the concentration of carbon dioxide (the principal greenhouse
gas) by more than 30% since preindustrial times.
Scientists predict that, if we continue on our current course,
concentrations of greenhouse gases in the atmosphere will reach roughly
twice current levels by 2100 -- a level not seen on this planet for the
past 50 million years. The Intergovernmental Panel on Climate Change
(IPCC), which represents the work of more than 2,000 of the world's
leading climate scientists, estimates that this will lead to an increase
in global temperature of 2 to 6.5° F. By way of comparison, the last ice
age was only 5 to 10° F colder than today.
Over the past year, new data from satellites, tree rings, ice cores, and
deep boreholes drilled in the Earth's surface have reinforced the broad
scientific consensus that human activities have started to affect the
climate and that continuing on a "business as usual" course will lead to
substantial warming in the next century. Studies have shown that the 20th
century has been the warmest century in the past 1,000 years and that the
1990s have been the warmest decade in that period, while 1998 has been the
single warmest year on record.
POTENTIAL IMPACTS OF CLIMATE CHANGE
Scientists predict a range of likely effects from global warming:
-
Extreme weather. As temperatures increase, so does the rate
of
evaporation. This acceleration of the so-called hydrologic cycle is
projected to increase the frequency and intensity of extreme weather
events such as floods and droughts. Last year's El Nino -- which produced
warmer and wetter conditions akin to those anticipated from global warming
-- offered us a window on the type of extreme weather that climate change
may bring, from heat waves and drought in Texas, to wildfires in Florida,
Mexico and Indonesia, ice storms in the northeastern United States, and
devastating floods in China and Bangladesh.
- Human health. Warmer temperatures are projected to
increase
fatalities
from heat stress and expand the geographic ranges for diseases like
malaria and dengue fever. Additional smog caused by warmer temperatures
could increase the incidence of asthma and other respiratory illnesses,
particularly among children and the elderly.
- Sea level rise. Scientists project that the sea level
will
rise by an
additional 6 to 37 inches by 2100, endangering island states and coastal
areas. A 20-inch rise could inundate 7,000 square miles of the U.S.
coastline, with Florida and the Gulf Coast at greatest risk.
- Agricultural impacts. Changes in growing seasons, water
availability,
soil moisture, and precipitation are expected to cause significant
regional shifts in food productivity, with decreased production in many of
the world's poorest regions. Water supplies and water quality may also be
affected, posing threats to irrigation, fisheries, and drinking
supplies.
- Damage to ecosystems. Many species are highly adapted
to
particular
climate conditions and may not survive substantial climate shifts. For
example, the United States may lose beech trees and sugar maples, and
western conifer forests are likely to shrink, as the tolerable climate
zones for these species shift hundreds of miles to the north.
PRESIDENT CLINTON'S DOMESTIC PLAN
Since 1993, President Clinton has put into place dozens of win-win
programs to develop and deploy energy efficient technologies and spur the
development and broader use of renewable energy. These efforts have
accelerated since the Kyoto climate change conference in 1997.
- Climate Change Technology Initiative. This vigorous
program of tax
incentives and investments focuses on energy efficiency and
renewable
energy technologies. The FY 1999 appropriations for these programs
totaled over $1 billion and represented a 25% increase over the prior
year. The President's FY 2000 budget proposes a still more accelerated
effort.
-
The tax incentive package contains $3.6 billion over five years
for
consumers who purchase energy efficient products and for producers of
energy from renewable sources. Highlights include: a tax credit of up to
$2000 for energy efficient new homes; a 10-20% credit for selected energy
efficient products for homes and buildings; a credit of up to $2000 for
rooftop solar systems; a credit of up to $4000 for qualifying electric,
fuel cell or hybrid vehicles; extension of the current 1.5 cents/kilowatt
hour credit for the production of electricity from wind and biomass; an
expansion of the biomass credit to cover additional sources; and a 1.0
cent/kilowatt hour credit for cofiring coal and biomass in power
plants.
-
The investment package contains nearly $1.4 billion in FY
2000 to
research, develop, and deploy clean energy technologies. This represents
a 34% increase over the amount appropriated in FY 1999. Highlights
include: increased funding for the Partnership for a New Generation of
Vehicles, a government-industry effort to develop cars that get up to
three times the fuel efficiency of today's cars; the Partnership for
Advancing Technology in Housing, which aims to improve the energy
efficiency of new homes by more than 50% and to retrofit 15 million
existing homes to make them 30% more energy efficient within a decade; a
stepped-up Bioenergy Initiative to develop advanced bioenergy
technologies; expanded research and development efforts in other key
renewable energy technologies, such as solar, wind, and geothermal energy;
and a Carbon Cycle Initiative, to deepen our understanding of
carbon
"sinks," such as forests and farmlands.
-
Electricity restructuring. Another core element of the
President's plan
involves restructuring the electricity industry by introducing competition
that will save consumers millions on their energy bills while reducing
greenhouse gas emissions. The Administration's restructuring proposal
would provide a profit incentive for generators to produce more
electricity with less fuel and to improve energy efficiency. It also
includes an aggressive, 7.5 percent renewable portfolio standard to
increase the use of electricity from renewable sources and a $3 billion
Public Benefits Fund to spur greater investment in energy efficiency and
renewables.
-
Industry Partnerships. The Administration is also engaged
in a wide
range of consultations with key industry sectors to improve energy use and
reduce emissions. For example, the Industries of the Future program works
cooperatively with the nation's most energy-intensive industries -- such
as aluminum, glass, chemicals, forest products, mining, petroleum
refining, and steel -- to develop technologies that increase energy and
resource efficiency.
-
Credit for Early Action. The Administration is committed to
working
with Congress and industry on legislation to reward companies taking
early, voluntary action to reduce their greenhouse gas emissions or
increase carbon sequestration.
-
Clean Air Partnership Fund. The President's FY 2000 budget
proposes
$200 million for the creation of a new Clean Air Partnership Fund to
support state and local projects to reduce both greenhouse gas emissions
and ground-level air pollutants.
-
Federal energy use and procurement. The President's plan
seeks to
substantially reduce the Federal government's own greenhouse gas emissions
by improving the energy efficiency of Federal facilities and activities
and reforming procurement practices. These actions are important in their
own right, since the Federal government is the nation's largest single
energy user, but they also set an important example for the private
sector.
-
Domestic emissions trading. The President has proposed a
domestic
emissions trading system to begin by 2008 so that we can achieve our
emissions target at the lowest possible cost. The U.S. has used emissions
trading successfully to reduce the pollution that causes acid rain --
exceeding environmental objectives at about 50% the expected cost.
-
Scientific research. The Administration is continuing its
strong
support for the U.S. Global Change Research Program, with nearly $1.8
billion in funding requested for FY 2000. This program provides a sound
science foundation for policy decisions by furthering our understanding of
human- and naturally-induced changes in the Earth's environment and
assessing the likely consequences of global warming.
DIPLOMATIC AGENDA
Thanks largely to U.S. leadership, the international climate change
agreement reached at Kyoto, Japan in December 1997, combines strong
environmental targets with elements of flexibility that will allow nations
to meet their targets in a cost-effective manner, including:
- Flexible market mechanisms. The Protocol includes
critically important
market mechanisms that can dramatically cut the cost of reducing
emissions. Chief among these are international emissions trading
and the
so-called Clean Development Mechanism (CDM), which will allow U.S.
companies to participate in joint clean energy ventures in the developing
world and earn credits from verified reductions in greenhouse gas
emissions.
-
Emissions targets are to be reached over a five-year commitment
period.
The first commitment period will be 2008-2012. Allowing emissions
to
averaged over a commitment period helps smooth out short-term fluctuations
due to economic performance or weather. Having a decade before the start
of the binding period will allow more time for companies to make the
transition to greater energy efficiency and/or lower carbon
technologies.
-
Emissions targets include all six major greenhouse gases.
This will
provide both more comprehensive environmental protection and additional
flexibility for nations and companies.
-
Activities that absorb carbon, such as planting trees, can be used
to
offset emissions. Including these so-called carbon sinks will
encourage
afforestation, reforestation, and better forestry and agricultural
conservation practices.
At the November 1998 UN climate change conference in Buenos Aires, the
parties agreed on a two-year timetable for filling in the key details of
the Kyoto Protocol in areas such as emissions trading, the CDM,
compliance, and the scope and use of carbon sinks. Buenos Aires also saw
progress on the issue of developing country participation as Argentina and
Kazakhstan announced their intention to take on binding emissions targets
for the 2008-2012 time period. The President has made clear that he will
not submit the Kyoto Protocol to the Senate without meaningful
participation from key developing countries in efforts to address global
warming.
ECONOMIC COST OF KYOTO
The Administration's economic analysis of the Kyoto Protocol concludes
that, if we do it right, the cost to the United States of meeting our
Kyoto target should be modest. Even without counting the impact of
domestic policies or the environmental, health, and economic benefits of
limiting climate change, estimates derived from economic modeling suggest
an emissions price in the range of $14 to $23 per ton of greenhouse gases.
In 2010, that would translate into an increase of $70 to $110 per year for
an average family's energy bill. This increase, however, would be
substantially offset by the decline in electricity prices resulting from
increased competition in a restructured electricity industry, as the
Administration and others have proposed. In addition, noted economists
have estimated the ancillary benefits of reducing greenhouse gas emissions
-- such as reduced air pollution -- could produce savings equal to one
quarter of the costs of meeting our Kyoto target.
CONCLUSION
For the past 25 years, efforts to protect the environment, whether by
cleaning our air, our water, or eliminating acid rain, have been
repeatedly assailed as a threat to our economy. Yet today, we have the
cleanest environment in a generation and the strongest economy in a
generation. President Clinton's balanced approach to the challenge of
climate change will allow us to continue to grow the economy and protect
the environment at the same time.
