New Study Expands Efforts to Understand Climate Implications of Methane Emissions

By Drew Nelson / Published: April 11, 2013

New supplies of natural gas are no doubt changing our energy landscape and, of all fossil fuels, natural gas appears to be a smarter choice because its carbon footprint is smaller when combusted than coal or oil. When talking about natural gas as part of a potential climate solution, though, it is important to recognize its unique position as either being a good or bad thing for global warming – depending upon the amount of uncombusted methane emissions that are released into the atmosphere.

No matter what market forces dictate for the future of gas, it’s EDF’s job to ensure that natural gas doesn’t become a detriment to public health or the environment. And, with respect to air quality and climate, getting better data on methane emissions is essential.

Methane can be emitted at various points across the natural gas system. Comprised mostly of methane, natural gas is a potent greenhouse gas. When it enters the atmosphere unburned, it has a higher warming potential than carbon dioxide, the principal contributor of man-made climate change. The more gas released, the more it undermines the climate benefits of using natural gas as compared to other fossil fuels. Yet there is no clear sense of how much and from where methane is leaking out from the system, as my colleague and Chief Scientist Steven Hamburg has explained here.

Over the last year EDF has been orchestrating a large-scale study of methane emissions with leading researchers in the field and industry to better understand the amount of methane emissions across the natural gas supply chain. To date the 30-month collaborative effort, with a $10 million overall budget, is bringing together almost 20 universities and research facilities and about 40 industry partners, collectively, in order to measure methane directly at potentially large emissions sources as gas moves from the formation underground to the wellhead and then on to the consumer.

Yesterday, the third part of EDF’s methane research study was announced, which focuses on the local distribution of natural gas (from city gate to customer meter) Read More »

In Texas, Freshwater Use For Oil And Gas Should Be Reduced Strategically

By Virginia Palacios / Published: April 9, 2013

Texas is suffering from a water deficit; one that is spurring lawmakers at the Texas Capitol to discuss unprecedented, and much needed, investments in our water infrastructure.  With roughly 98 percent of the state in drought and water use restrictions in place in 70 percent of Texas counties as of April 3, 2013, it is crucial that our legislators consider every tool available to protect Texas’ water supply.  One approach is reducing freshwater use in the oil and natural gas sector, which can help alleviate competition for scarce water resources; however, this should be deployed at strategic places and times to minimize pollution risks and ensure a sustained future water supply for Texas.

In the Texas Legislature, the House recently passed a bill which will provide $2 billion to fund water supply projects.  It might surprise you to hear that this high price tag represents less than 10 percent of the state funding that will be needed over the next 50 years to sustain water supplies for Texas’ growing population.  In light of this, it is essential that legislators enact bills that encourage responsible water management solutions. Although the oil and gas industry’s water use appears miniscule when considered on a statewide basis, even small amounts can have a big impact in the most water stricken areas. EDF created a map of the counties in Texas currently being impacted by water scarcity and that would benefit greatly if the oil and gas sector reduced its use of freshwater.

Data used to create the map revealed the following:

  • The majority of water used for Texas oil and gas development in 2011 was in 13 counties, ten of which currently have water restrictions in place.
  • For 12 counties, oil and gas water use made up at least 25 percent of overall county-wide demand in 2011.
  • In 15 counties, oil and gas water use is projected to be greater than or equal to 25 percent of the water deficit in those counties in 2020.
  • In five counties, 100 percent of the water deficit projected for 2020 can be met by cutting oil and gas water use by half.

The oil and gas industry is a prime candidate for reducing its reliance on freshwater because – unlike the agriculture and municipal sectors – using non-freshwater is technologically feasible.  Some of the most popular alternative water sources for the oil and gas industry include brackish (or salty) water, treated flowback water from hydraulic fracturing and reclaimed water from public wastewater treatment plants.  Taking advantage of these options could be a win-win-win for industry, people and the environment.

An Old-Timer Reflects On The Importance Of New Technology To Battle Methane Emissions, And What You Can Do About It

By Mark Brownstein / Published: April 5, 2013

Anyone younger than 30 may not understand what a skipping record sounds like;  in their lives, listening to tunes has more often meant hitting a playlist on iTunes or streaming Pandora, than it has meant dusting off an old record. To us “old” folks who remember when clunky 8-track tapes were the height of portable music cool, today’s options are nothing less than astounding.

Believe it or not, I was thinking about this as I participated yesterday in a panel at the World Resource Institute in Washington, D.C. to discuss their new paper titled, “Cleaning the Air: Reducing Upstream Greenhouse Gas Emissions From U.S. Natural Gas Systems.”  Reviewing the report, and reflecting on EDF’s own work to understand and reduce methane and other air pollution, it’s clear a huge opportunity exists for technology to revolutionize air quality practices in the gas industry, just as it reengineered production and delivery of audio in the music industry. And the prospects are very bright that it will.

Champions of natural gas like to say that natural gas is a preferred fossil fuel alternative to coal and oil because it has less carbon content than either, and therefore, when burned, produces less carbon dioxide, which is the a primary cause of global warming. This is true.

But what is often not said is that natural gas is primarily made up of methane, which itself is a powerful greenhouse gas pollutant, many times more powerful than carbon dioxide, particularly when methane is first released into the atmosphere. Even small leaks at the wellhead or along the infrastructure used to process and transport the gas to our power plants, homes and businesses can undo much of the greenhouse gas benefits we think we are getting when we substitute natural gas for coal or petroleum sources.  Read More »

A Silk Purse From A Sow’s Ear: Federal Cuts May Spur Environmental And Energy Savings

By Jon Goldstein / Published: April 2, 2013

Holly Pearen, EDF’s Attorney for the Natural Gas Campaign, contributed to this blog post.

The federal government notified 36 states last week that it plans to temporarily stop monthly mineral revenue payments as a part of the mandatory sequestration budget cuts. These cuts will hit western states especially hard with an estimated $26 million cut coming to New Mexico over the next six months, $8.7 million to Utah, $8.4 in Colorado and $5.5 in California, while North Dakota and Montana will see $3.2 and $2.5 million in cuts, respectively, according to data from the U.S. Department of Interior’s Office of Natural Resources Revenue.

However, no state will be hit as hard as mineral resource and federal lands-rich Wyoming, which has been notified to prepare itself to lose $53 million in federal mineral revenue payments through July.

The money is the state’s share of royalties paid by producers who operate on federal leases in Wyoming. Not surprisingly, Wyoming officials are very unhappy with the federal plan, both its details and the way it was announced to the states via letter with little forewarning. As Wyoming Governor Matt Mead said in a statement: “As far as communications go, this method of passing along significant information that greatly impacts Wyoming gets a grade of F minus or worse. It is not acceptable.”

While Governor Mead has vowed to fight the plan and is working with the Wyoming Attorney General, Wyoming’s congressional delegation and neighboring states to come up with a strategy to oppose the cuts, we would like to offer a suggestion. Perhaps Interior should make up the shortfall owed to the states by charging royalties on vented and flared natural gas? Read More »

Industry And Environmentalists Make Progress On Fracking

By Mark Brownstein / Published: March 29, 2013

This commentary was originally posted on our EDF Voices blog.

Worthy public policy initiatives get announced every day of the week, and reporters mostly greet them with a shrug. But last week’s announcement of a new center designed to set standards for shale gas development in the Appalachian Basin triggered a wave of media attention.

The Washington Post called the Center for Sustainable Shale Development (CSSD), “a heartening breakthrough in the war over fracking.” And the Associated Press wrote: “Some of the nation’s biggest oil and gas companies have made peace with environmentalists, agreeing to a voluntary set of tough new standards for fracking in the Northeast….”

I agree that this is a big deal, and not just because EDF played an important role in the two years of negotiation that led to the formation of this group. It’s a rare to see environmentalists and some of the nation’s biggest energy companies working together to improve the safety of natural gas operations.  This coalition is a step in the right direction to better protect the quality of life for people living among the gas fields.

But, I also need to make a few points clear.

First, the standards put forth by CSSD are no substitute for strong regulation and enforcement.   Voluntary efforts by industry leaders help distinguish the best from the rest and raise the bar for all, but the only path to full protection of our air, water, and health is regulation and enforcement that apply to all.    Read More »

New BLM Proposals For Large Oil And Gas Fields Ignite Wyoming Air Quality Concerns

By Jon Goldstein / Published: March 7, 2013

Wyoming is already one of the country’s top natural gas producers. And large new developments under review by the

U.S. Bureau of Land Management totaling more than 25,000 new wells in the coming years could further solidify Wyoming’s status as a national energy leader.

But what will this leadership look like? Will this series of development projects lead to worsening air quality or set an example for safe, responsible development?

The first of these, the Continental Divide – Creston Project, is alone one of the largest onshore natural gas developments ever proposed on federal lands in the United States. This enormous development slated for the Wamsutter area of south-central Wyoming, includes drilling nearly 9,000 new natural gas wells across 1,672 square miles (or 1.1 million acres) of public and private lands — an area a bit larger than the state of Rhode Island. The well-known Jonah Field in western Wyoming, by comparison, covers about 21,000 acres and includes about 3,500 wells.

The scale, concentration and vicinity of new wells proposed by the CD-C project are fueling concern for regional air quality issues. If managed improperly, this project could lead to more unhealthy air for local residents and workers.

Unhealthy air, as a result of oil and gas development, has been a particular issue in Pinedale, a community just northwest of the CD-C proposal in Wyoming’s Upper Green River Basin. The past few winters have earned the area unwanted national attention for its U.S. Environmental Protection Agency nonattainment designation for ground-level ozone pollution — one of the first non-urban areas to report such high levels of smog.
