The rapid expansion of unconventional natural gas development has reshaped the U.S. energy picture through increased production and reduced prices of natural gas. The shale gas production boom has also ignited divisive debates over its near- and long-term environmental impacts.
New data from the U.S. Energy Information Administration (EIA) reveals a troubling trend: Coal-fired power generation—and its associated greenhouse gas emissions—were on the rise as 2012 came to an end.
According to the data, which was released yesterday, natural gas prices have risen significantly since April of 2012, prompting a rise in coal-fired electric generation (see figure below). This increase marks a dramatic change from the trends we’ve seen in the United States over the past several years. U.S. energy-related carbon dioxide (CO2) emissions from the power sector had been falling, mostly due to more electricity being generated by renewables, slowed economic growth, and a greater use of low-cost natural gas, which produces roughly half the CO2 emissions of coal during combustion.
The new uptick in gas prices and coal use suggests that we cannot simply rely on current market forces to meet America’s emissions-reduction goals. In fact, EIA projects that CO2 emissions from the power sector will slowly rise over the long term. To keep emissions on a downward trajectory, the Administration must use its authority to prompt greater, immediate reductions by putting in place emissions standards for both new and existing power plants.

The national conversation around climate change has resumed. In both the Inauguration and State of the Union addresses, President Obama devoted considerable time to the issue, including his declaration that “we must do more to combat climate change.”
For some, this call to action may come as a surprise, as multiple recent reports have hailed falling U.S. greenhouse gas emissions. Bloomberg New Energy Finance, for example, found that carbon dioxide emissions in the United States dropped 13 percent over the past five years.
However, the story is not as simple as it seems. By taking a closer look, it becomes clear that the United States needs to do more to shift to a safer pathway.
Here are three popular misconceptions about U.S. greenhouse gas emissions and the underlying truth behind them:
President Obama made it abundantly clear during the State of the Union address last night that he will direct his Administration to take on climate change. The president reiterated the urgency for action, citing climate impacts we’re already seeing like record high temperatures, heat waves, drought, wildfires, and floods. “We can choose to believe that Superstorm Sandy, and the most severe drought in decades, and the worst wildfires some states have ever seen were all just a freak coincidence,” he said. “Or we can choose to believe in the overwhelming judgment of science--and act before it’s too late.”
The president urged Congress to rise to the challenge by pursuing a “bipartisan, market-based solution,” but he also noted that the Administration will take action—with or without Congress. “I will direct my Cabinet to come up with executive actions we can take, now and in the future, to reduce pollution, prepare our communities for the consequences of climate change, and speed the transition to more sustainable sources of energy,” the president said.
This statement is especially significant because the Administration can take meaningful actions right now even without new legislation. WRI recently released a report detailing the immediate steps federal agencies can take to combat climate change. The four greatest opportunities to reduce greenhouse gas emissions in the short term include:
The WRI report, "Can The U.S. Get There From Here?" examines pathways for United States greenhouse gas reductions that can be taken at the federal and state levels using existing authorities.
Franz Litz, Executive Director of Pace Law School's Energy and Climate Center, also contributed to this post.
WRI just released a new report that answers the important question: Is the United States on track to meet its climate change commitments?
The report, Can the U.S. Get there from Here? Using Existing Federal Laws and State Action to Reduce Greenhouse Gas Emissions, looks at whether the U.S. Administration--without congressional action--can meet its goal of reducing greenhouse gas (GHG) emissions 17 percent below 2005 levels by 2020. (This is a goal the United States committed to in 2009.)
According to our research, the United States is not yet on track to meet the 17 percent target. However, the country can get there using existing federal laws, provided that the Administration takes ambitious action. We also found that states can play a significant role in reducing GHG emissions and can help supplement federal action.
This report is a legal and technical analysis that explores three levels of ambition for the Administration: “lackluster,” “middle of the road,” and “go-getter.” These scenarios are based on an extensive review of the technical literature on what is possible. The interactive graphic below highlights what can be accomplished through federal action under these scenarios.

As we’ve seen recently with Hurricane Sandy, epic drought, and wildfires, climate change visibly impacts lives and livelihoods throughout the United States. Global warming’s effects extend beyond people, wildlife, and ecosystems, though: They’re threatening America’s energy infrastructure.
Today, I testified on this very subject before the Energy and Power Subcommittee of the House Energy and Commerce Committee at a hearing entitled “American Energy Security and Innovation: An Assessment of North America’s Energy Resources.” I highlighted the energy risks and opportunities climate change presents, the role that clean energy should play, and actions Congress can take to mitigate global warming’s threats. Excerpts from the testimony are included below, or you can download my full testimony.
Climate Change Threatens Energy Infrastructure
Climate instability directly affects the future security of the U.S. energy sector. For example:
- Each successive decade in the last 50 years has been the warmest on record globally, and according to the U.S. National Climate Assessment, average temperatures will continue to rise. Energy demand is directly impacted by these temperature increases. A recent study in Massachusetts estimates that rising temperatures could increase demand for electricity in the state by 40 percent by 2030.
Following is a statement by Andrew Steer, President and CEO, World Resources Institute:
Temperatures hit an unseasonably warm 61˚F in Washington D.C. earlier this week. The Middle East is blanketed in record rainfall and rare heavy snowfall, ending a nearly decade-long drought. Australia witnessed its hottest day on record this past week, stoking wildfires. And China is experiencing a bitterly cold winter, where temperatures are the lowestthey’ve been in almost three decades. We’re only two weeks into 2013, and already we are getting a reminder of the extreme year we just emerged from.
2012: A Year of Extreme Weather
How extreme were last year’s weather and climatic events? In the continental United States, 2012 was the hottest year on record and the second most extreme year, according to scientists from the National Oceanic and Atmospheric Administration (NOAA). On top of that, the United States experienced 11 extreme weather events that each caused more than $1 billion in damages.
And 2012 did not spare the rest of the world; it brought severe drought to the African Sahel, torrential rains to China, Europe’s worst cold snap in 25 years, and flooding in Manila and Bangladesh, among other devastating events.
We took stock of 2012’s extreme events in an interactive timeline. It is by no means comprehensive, but reminds us how climate change is affecting global communities and citizens’ lives, livelihoods, infrastructure, and ecosystems.
The draft U.S. National Climate Assessment was released last week, confirming that the climate is changing, that it is primarily due to human activities, and that the United States is already being adversely impacted. These top-line messages should come as no surprise, as they reconfirm the major findings of previous National Climate Assessments and of the Intergovernmental Panel on Climate Change’s recent reports.
But the 1,000-plus pages of the Assessment also carry important findings—many of which have not been highlighted in media reports thus far. WRI’s experts reviewed the assessment in its entirety. Below, we boil down some of the highlights from this comprehensive body of work, including its findings on how increases in greenhouse gas emissions have impacted temperature, sea level rise, precipitation, ice cover, ecosystems, and human health in the United States and globally.
Build-up of greenhouse gases in the atmosphere has already caused America’s average temperature to rise by 1.5 ˚F since 1895, according to the assessment. With continued increases in emissions, U.S. temperatures are projected to increase 5-10˚F by the end of the century. Rising temperatures have implications for human health, drought, storm intensity, and species and ecosystem health, among others. A few other notable statistics include:
