U.S. Natural Gas Exports: Friend or Foe?

U.S. natural gas production is booming. According to the Energy Information Administration (EIA), production grew by 23 percent from 2007 to 2012. Now—with production projected to continue growing in the decades ahead—U.S. lawmakers and companies are considering exporting this resource internationally. But what are the climate implications of doing so?

This is a topic I sought to address in my testimony yesterday before the U.S. House of Representatives Energy and Commerce Subcommittee on Energy and Power. The hearing, “U.S. Energy Abundance: Exports and the Changing Global Energy Landscape,” examined both the opportunities and risks presented by exporting liquefied natural gas (LNG). I sought to emphasize a number of points that are often overlooked in this discussion; in particular, fugitive methane emissions and cost-effective options for reducing them.

Environmental Impacts of Natural Gas Production

While burning natural gas releases half the amount of carbon dioxide as coal, producing the fuel comes with considerable environmental risks (see: here, here, and here). We’re already seeing these risks play out domestically. In addition to habitat disruption and impacts on local air and water quality, one of the most significant implications of natural gas production is fugitive methane emissions.

5 Reasons Why It’s (Still) Important to Reduce Fugitive Methane Emissions

The U.S. Environmental Protection Agency (EPA) recently released its annual greenhouse gas (GHG) inventory report. Using new data and information, the EPA lowered its estimate of fugitive methane emissions from natural gas development by 33 percent, from 10.3 million metric tons (MMT) in 2010 to 6.9 MMT in 2011. While such a reduction, if confirmed by measurement data, would undeniably be a welcome development, it doesn’t mean that the problem is solved.

There are still many reasons why reducing fugitive methane is important. Even better, WRI’s recent analysis finds that we have the technologies and policy frameworks to do so cost effectively.

Here are five big reasons we should care about fugitive methane emissions:

1) Emissions Are Still Too High.

Methane is a potent greenhouse gas and a key driver of global warming. Methane is 25 times stronger than carbon dioxide over a 100-year time period and 72 times stronger over a 20-year period. In fact, 6.9 MMt of methane is equivalent in impact to 172 MMt of CO2 over a 100-year time horizon. That’s greater than all the direct and indirect GHG emissions from iron and steel, cement, and aluminum manufacturing combined. Reducing methane emissions is an essential step toward reducing U.S. greenhouse gas emissions and slowing the rate of global warming.

Exploring Prospects for U.S. Coal Exports to China

This post originally appeared on ChinaFAQS.org.

The United States and China are the world’s two largest economies. They are also the two largest producers and consumers of coal, and the largest emitters of carbon dioxide. In recent years, however, their paths on coal have started to diverge.

Over the last few years, coal consumption has dropped dramatically in the United States, mainly due to low natural gas prices. In response to weak domestic demand, the U.S. coal industry has been rushing to find its way out to the international market. Last year, U.S. coal exports hit a historical high of 114 million metric tons.

However, it is worth noting that the shift away from coal in the U.S. may not be permanent. As my colleague, Kristin Meek, pointed out in an earlier blog post, coal use in the U.S. power sector was on the rise again towards the end of 2012, likely driven by the new uptick in natural gas prices.

On the other side of the globe, China’s appetite for coal continues to grow. In response, Chinese power companies are looking to tap the international coal market for sources that are more reliable and cost competitive. Among those markets is the United States. In 2012, China imported 290 million metric tons of coal. China was the third largest destination for U.S. coal exports, behind the Netherlands and the U.K.

The Race Against Climate Change

This post originally appeared on the National Journal's Energy Experts blog. It is a response to the question: "What's holding back energy and climate policy?"

We are in a race for sure, but it is not a race among various national issues. It’s a race to slow the pace of our rapidly changing climate. The planet is warming faster than previously thought, and we cannot afford to wait for national politics to align to make progress in slowing the dangerous rate of warming.

Recent events, like the tragedy at Sandy Hook elementary school, propelled gun control front and center. Last year’s elections shifted the national conversation on immigration. Climate change, too, should demand the attention of our national leaders.

The evidence of climate change is clear and growing. In 2012, there were 356 all-time temperature highs tied or broken in the United States. As of March, the world had experienced 337th consecutive months (28 years) with a global temperature above the 20th century average. Global sea levels are rising and artic sea ice continues to shrink faster than many scientists had predicted.

There are indications that Americans are deepening their understanding about climate change, especially when it comes to its impacts. People are beginning to connect the dots around extreme weather events, rising seas, droughts and wildfires, which have been coming in increasing frequency and intensity in recent years. The National Oceanic and Atmospheric Administration calculated that weather-related damages in the United States were $60 billion in 2011 alone.

Food and Fuel: 2 Grand Challenges Facing Us this Earth Day

Since the very first Earth Day more than four decades ago, the environmental movement has tackled a wide range of problems, including air pollution, contaminated water, deforestation, biodiversity loss, and more. But this Earth Day, I propose that there are two fundamental issues the movement must address over the coming decade if it is ever to defuse the tension between development and the environment. In fact, these two issues underlie many, if not most, of the world’s environmental challenges.

I’m referring here to the human quest for food and the human quest for fuel.

Unsustainable Food Production

Food production has significant―but often underestimated―impacts on the environment. Take climate, for instance: About one-quarter of the world’s annual greenhouse gas emissions are agriculture-related. In particular, nearly 13 percent of global emissions comes from livestock, fertilizer use, and farm-related energy consumption, while another 11 percent results from the clearing of forests and other ecosystems, primarily for agriculture.

Bring in Smart Policies, Clear the Air on Clean Energy

This post was co-authored with Jamshyd Godrej, chairman of Godrej & Boyce Mfg. Co. Ltd and a WRI Board Member. It originally appeared in The Economic Times.

Ministers are gathering in New Delhi today to address an urgent challenge: how to unlock the full potential of clean energy to drive economic growth, expand energy access, and protect the climate. The 4th Clean Energy Ministerial — which brings together energy ministers and other delegates from more than 20 leading economies — is a critical opportunity to inject new life into the global clean energy transition.

While we've seen progress on renewable energy, the sector still faces barriers to increase financial support and create strong national policies that will enable it to flourish. First, some good news: The renewable energy market has blossomed in recent years. In just the last decade, global clean energy investment has increased five-fold, from $50 billion a year to more than $250 billion. And more than 100 countries have renewable energy targets in place.

India has set itself on a remarkable journey by ushering in renewable energy growth. The National Action Plan on Climate Change, launched in 2008, aims to have 15 percent of India's electricity consumption from renewable energy by 2020. Currently, the country produces slightly more than 12 percent of its energy from renewables, putting it on track for that goal. India has been using various policy levers to advance renewable energy, including tax and generation-based incentives, capital subsidies, and feed-in tariffs. The Renewable Portfolio Obligations is also providing support for renewable energy developers. Even so, the country is not yet achieving its full potential — which is critical for the 400 million people who lack access to basic electricity.

Capturing the Fugitives: Reducing Methane Emissions from Natural Gas

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.

A Close Look at Fugitive Methane Emissions from Natural Gas

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.

Lessons from Thailand: Mobilizing Investment in Energy Efficiency

Developing countries will need about $531 billion of additional investments in clean energy technologies every year in order to limit global temperature rise to 2° C above pre-industrial levels, thus preventing climate change’s worst impacts. To attract investments on the scale required, developing country governments, with support from developed countries, must undertake “readiness” activities that will encourage public and private sector investors to put their money into climate-friendly projects.

WRI’s six-part blog series, Mobilizing Clean Energy Finance, highlights individual developing countries’ experiences in scaling up investments in clean energy and explores the role climate finance plays in addressing investment barriers. The cases draw on WRI’s recent report, Mobilizing Climate Investment.

The development of Thailand’s energy efficiency sector is an interesting case study. It demonstrates how strong government leadership combined with strategic support from international climate finance can drive the transition toward an energy-efficient economy.

In the early 1990s, Thailand’s economy was growing rapidly at 10 percent per year; the power sector was growing even faster. The government recognized that conserving energy would provide a low-cost way to meet its citizens’ rising demand for energy.
