President Obama knows that climate change is the
defining challenge of our time and his presidency. Early in his administration,
he committed to putting the United States on a path to reduce the carbon
pollution that causes climate change. This commitment—made in Copenhagen in
2009—is a pledge by the United States to reduce its greenhouse-gas pollution to
17 percent below 2005 levels by 2020. The president took significant actions
during his first term to fulfill that promise, and news reports indicate that
on Tuesday he will announce the most important step in this effort: reducing
carbon pollution from power plants.
There are three primary policies undertaken by the
Obama administration that have reduced carbon pollution responsible for climate
change:
Making cars more efficient. The president worked
with the auto industry, autoworkers, and states to implement the first
motor-vehicle greenhouse-gas tailpipe standard, along with fuel-economy
standards of 54.5 miles per gallon in 2025—double the standard in 2010. These
measures will save 2 billion metric tons of carbon pollution over the lifetime
of new vehicles sold between 2017 and 2025.
Investing in clean energy as part of an economic
recovery strategy. The American Recovery and Reinvestment Act of 2009, or ARRA,
committed more than $80 billion to clean energy, helping weatherize 1 million
low-income homes to save families an average of $400 annually in lower utility
bills. ARRA investments also grew the wind and solar industries, helping to
double domestic renewable electricity generation in four years.
Reducing super pollutants through domestic,
international, and bilateral actions. Carbon dioxide is the most abundant and
long-lasting greenhouse gas, but there are other less-common gases that
generate significantly more warming per molecule compared to carbon pollution.
Hydrofluorocarbons, or HFCs, for example, which are used as a refrigerant and
coolant, can be up to thousands of times more potent than carbon dioxide. In
early June the Obama administration convinced China to support the phase down
of HFCs under the Montreal Protocol, which is essential to convincing the major
developing countries to participate in this effort. Securing this agreement
would reduce climate change pollution by around 90 billion tons of
CO2-equivalent emissions by 2050 and avoid half a degree Celsius of warming by
the end of the century.
The first two measures were partially responsible
for reducing 2011 greenhouse-gas levels to 7 percent below 2005 levels,
according to the Environmental Protection Agency. The U.S. Energy Information
Administration predicts additional domestic reductions in carbon pollution
between now and 2017, but emissions will rise again without the adoption of
additional reduction policies. Getting our greenhouse-gas pollution to 17
percent below 2005 levels will require at least one more big step:
carbon-pollution reductions from power plants.
No new laws are required to achieve these
reductions. In 2007 the Supreme Court required the Environmental Protection
Agency, or EPA, to determine whether greenhouse gases should be regulated under
the Clean Air Act as an endangerment to public health. Then-President George W.
Bush balked at enforcing the law despite the recommendations of the EPA
administrator and agency scientists to do so. EPA Administrator Lisa Jackson
finally made the endangerment finding under President Obama in 2009. In 2012
EPA proposed a carbon-pollution standard for new, yet-to-be-built power plants.
Hopefully, the president will call on EPA to take the next step and develop
standards for carbon pollution from existing plants.
Power plants are the single-largest uncontrolled
source of climate pollution, producing one-third of greenhouse-gas pollution in
the United States, according to EPA. The World Resources Institute found that
setting ambitious standards are the most important reduction measures to be
taken in order to meet the 2020 goal. And the Natural Resources Defense Council
found that a system of strong but flexible standards, along with state-led
compliance mechanisms combined with existing reductions, would achieve
three-quarters of the 17 percent reduction goal.
In addition to slashing industrial carbon pollution,
we must also keep our economy running with renewable electricity and greater
energy efficiency. When the president announces the next steps to cut
greenhouse-gas pollution, he should also seize the many opportunities to
improve the nation’s energy efficiency and to deploy more renewable energy. The
president can utilize existing authorities to make government buildings more
energy efficient, which would not only reduce pollution but save taxpayers
money too. The federal government can hire energy-services companies to reduce
its energy use. The president can also build on the Better Buildings Initiative
to link private companies with federal resources to help finance
energy-efficiency retrofits. In addition, the Obama administration should
approve the eight pending appliance-efficiency standards that have been stalled
for more than a year. Each month of delay costs consumers $200 million in lost
energy savings and yields 3 million metric tons of carbon pollution, according
to the Appliance Standards Awareness Project.
The amount of electricity produced by wind, solar,
and other renewable power sources has nearly doubled under President Obama. The
Department of the Interior has spurred renewable-energy growth on public lands
by permitting projects that will ultimately produce more than 10,000 megawatts
of renewable power. But much more can be done. Energy production on public
lands is still heavily skewed toward the private production of fossil fuels
burned for electricity. The Center for American Progress proposed a “clean
resources standard” for public lands and waters to set an aggressive yet
achievable new target: 35 percent of electricity produced from resources coming
from public lands and waters must be renewable by 2035. Currently, 66 percent
of the resources from public lands used for electricity are from coal, while
only 1 percent is from wind, solar, and geothermal resources combined.
We must also continue to lead the international
community to address climate change. Reducing HFCs through the Montreal
Protocol is a critical first step to phasing out other harmful super
pollutants, including methane and black carbon. More effort is needed, however,
to scale up the ambition of these countries and expand the members to include
the world’s biggest emerging economies, including China and India.
While the nation cuts climate change pollution, we
must also help communities cope with climate change impacts that are already
here by helping them become more resilient to storms, floods, droughts, heat
waves, and fires. Every $1 invested in community resilience reduces extreme
weather damage by $4, according to the Federal Emergency Management Agency. To
save lives and money, the Obama administration must identify revenue sources to
assist threatened communities.
Reducing pollution from power plants, using energy
more efficiently, reducing super pollutants, and moving toward renewable energy
are a powerful set of tools for fighting climate change. We’re looking forward
to the president building on his successful record by taking meaningful action
on each of these.
