WRI established its U.S. office in 1982. We work to improve water quality, increase awareness of local climate change impacts, and identify cost-effective emissions-reduction opportunities in the United States. Learn more about our work in the United States.

The rapid expansion of natural gas development in the United States has been a double-edged sword. While natural gas supporters are quick to point out its economic benefits and green attributes—natural gas produces roughly half the carbon dioxide emissions of coal during combustion—this isn’t the whole story. Natural gas comes with environmental consequences, including risks to air and water quality.

One risk is “fugitive methane emissions,” potent greenhouse gases that escape into the atmosphere throughout the natural gas development process. This methane—which is 25 times more potent than carbon dioxide over a 100-year timeframe—contributes to global warming and undercuts the climate advantage that cleaner-burning natural gas has over coal and diesel. (Learn more about fugitive methane emissions in our recent blog post.)

Despite the controversy surrounding natural gas development, energy forecasts suggest that natural gas is here to stay. Fortunately, several pathways are available to limit the climate impacts associated with its development. WRI just released a working paper, Clearing the Air: Reducing Upstream Greenhouse Gas Emissions from U.S. Natural Gas Systems, which outlines a number of state and federal policies and industry best practices to cost-effectively reduce fugitive methane emissions. We find that with the right amount of reductions, natural gas does offer advantages from a greenhouse gas (GHG) emissions perspective over coal and diesel.

Reducing Upstream Greenhouse Gas Emissions from U.S. Natural Gas Systems

This working paper focuses primarily on evaluating and reducing upstream methane emissions in the natural gas sector. We outline a number of state and federal policies and industry best practices to cost-effectively reduce fugitive methane emissions.

Natural gas is booming in the United States. Production has increased by 20 percent in the last five years, fueled largely by technological advances in shale gas extraction. Other countries--including China--are now studying our experience with this abundant new resource.

But the growing role of natural gas in the U.S. energy mix hasn’t come without controversy. Natural gas development poses a variety of environmental risks. In addition to habitat disruption and impacts on local water and air quality, one of the most significant concerns is the climate impact resulting from the “fugitive methane emissions” that escape into the atmosphere from various points along the natural gas supply chain.

So what are fugitive methane emissions, and how big of a problem are they? How do emissions from natural gas compare to those from coal? And are there ways to mitigate them? The answers to these questions will help us better understand how natural gas development will affect climate change.

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.

America is blessed with abundant energy sources, from an array of traditional fuels and natural gas to solar, wind, and other renewable resources. But as the pressure on these resources grows, the United States must have a plan to ensure a stronger and more sustainable future. In today’s world, any smart and effective energy strategy must take into account the risks of climate change.

Climate change impacts are already here. They do not have a political affiliation, nor are they constrained by state boundaries. Moreover, climate impacts are taking a serious toll on America’s infrastructure and economy.

Let’s look at some examples:

America’s coastal areas are particularly vulnerable, as rising sea levels and heavier precipitation are increasing the impacts of hurricanes and other storms. More than 58 percent of U.S. gross domestic product, some $8.3 trillion, is generated in coastal areas (including the Great Lakes). This accounts for some 66 million jobs. Florida, in particular, faces significant threats due to rising seas.

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.

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:
