Earlier this week, a prestigious scientific journal, the Proceedings of the National Academy of Sciences (PNAS) published “Measurements of methane emissions at natural gas production sites in the United States.”  This study is the first in a comprehensive research initiative that Environmental Defense Fund is helping to produce with more than 90 partner universities, scientists, research facilities and natural gas industry companies. This effort, the largest scientific undertaking in EDF’s history, is an unprecedented attempt to measure where and how much methane is being released across the entire natural gas supply chain.

By the time the work is finished, around the end of 2014, scientists working with EDF will have completed sixteen studies characterizing methane emissions in five key areas of the natural gas system: production, gathering and processing,transmission and storagelocal distribution and use in operating and fueling heavy and medium weight trucks.

The study that published Monday was led by Dr. David Allen of the University of Texas at Austin (UT) and is based on some of the first-ever direct measurements of methane emissions from shale gas wells that use hydraulic fracturing, or “fracking.”

Methane Research: The Data Pursuit Continues

Source: Kinder Morgan

Is natural gas really better for the climate? This may seem like a simple question. After all, natural gas is the cleanest burning fossil fuel.  And data from the Energy Information Administration in April showed a downward trend in U.S. energy-related carbon dioxide (CO2) emissions. A move many experts believe is largely attributed to the increased production of U.S. natural gas and the shift it has caused in the power sector – old, dirty coal plants being retired because new natural gas plants are more competitive.

But, this is only part of the story. Natural gas is comprised primarily of methane, and unburned methane is an incredibly potent greenhouse gas – 72 times more powerful than CO2 over the first two decades it is released.

The oil and gas industry is one of the largest domestic sources of methane, and while new gas reserves are being drilled every day,  too little is known about how much and from where methane is leaking out from across the natural gas system. Lack of direct measurements has been a challenge, as EDF’s Chief Scientist Steven Hamburg explains here.

The need for better data to understand and control methane emissions in order to understand the true climate opportunity of natural gas led to EDF’s largest scientific research project. This effort currently involves about 85 academic, research and industry partners subdivided over five areas of the value chain (production, gathering and processing, transmission and storage, local distribution and transportation).  Read More »

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

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 »

Industry And Environmentalists Make Progress On Fracking

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 »

“Promised Land”: A Love Letter To Longmont

Source: The Daily Digger

Promised Land is not a movie about “fracking.” You will be sorely disappointed if you go to the theatre expecting to see lurid visuals of sinister-looking waste water ponds, plumes of diesel soot and road dust, or bucolic landscapes scarred by roads and pipes. You will see none of that.

Promised Land is a movie about what happens before the drilling rigs and man camps rumble into town. It is the story of a rural community, proud but poor, struggling to reconcile itself with an enormous economic opportunity that comes at an enormous cost.

And, despite what you may have read in the blogosphere, it is not reflexively anti-natural gas. The movie actually does a fairly decent job of presenting all sides of the shale gas development debate. I was intrigued to read a Pittsburgh Post-Gazette article from this past June where John Krasinski, a star in the film and co-author of the screenplay, revealed that he originally conceived the story as a community facing major wind farm development. Krasinski made the switch because natural gas development is more topical, and more visceral, than wind development.  His primary point in making the film was to explore what happens when money and power come to a rural community that has neither.

I suspect the reason why the natural gas industry is so on edge about this movie is because the plot device which propels the story forward is a community referendum on whether development will be allowed within its borders. This is exactly the situation the industry faces in Longmont, Colorado, and to the same or similar degree in many other communities around the country.

The central question the movie poses is whether any amount of potential future prosperity is worth sacrificing a pastoral way of life that has defined a community for generations. Worry over polluted water is part of what fuels the townspeople’s anxiety over what to do, but it is far from their only concern.

Does a community have the right to regulate or prohibit industrial development in its borders?  It’s a tricky legal question currently playing out in Colorado and elsewhere around the country, and there is no simple answer.

One thing is certain: the natural gas industry must be forthcoming and honest about the risks that unconventional oil and gas development create, proactive in taking the steps necessary to minimize those risks, and willing to collect and publicly disclose the data necessary to enable communities to evaluate for themselves whether their health and environment are being fully protected. Many people distrust whether industry can develop shale gas safely, and it’s understandable why they are concerned – especially given recent media reports about industry hiding many of the chemicals they use behind questionable “trade secret” claims.  It appears that even the most basic steps toward greater transparency are grudging and incomplete.

In Promised Land, citizens are repeatedly lied to with predictable results. In real life, the natural gas industry has the ability to write a different story through the actions it takes to address community concerns, measure performance and disclose results. That’s a story I want to see.

New York’s Decision To Take Time For A Public Health Review Of Hydraulic Fracturing Is A Wise Move

Last week’s announcement that New York State Department of Environmental Conservation (NY DEC) has asked New York State Department of Health (NY DOH) to undertake a review of the work NY DEC has done to date on regulating high volume hydraulic fracturing is welcome news.  Citizens across New York have raised legitimate questions about whether NY DEC is doing all that it can do to develop regulations that protect public health.  Review by a qualified panel of public health experts, under the auspices of NY DOH, is a necessary step to answer these legitimate concerns.  Getting the rules right in New York is critically important, so we believe that taking the time for a public health review is a wise move.

Of course, it is critically important that this review be done well.  The experts convened by NY DOH should be qualified, independent public health professionals.  The scope of their review should be broad and the work that they do should be thorough.  Science, not politics, should guide their work.  Above all, NY DEC should stand ready to act on any recommendations that come from this review.  EDF looks at this an opportunity to make NY DEC’s good work to date better, and we hope NY DEC sees it that way too.

EDF believes that New York’s regulatory regime should include the development of a public health baseline across the communities where shale gas development would be likely to occur, coupled with a rigorous, on-going effort by NY DOH to track key public health metrics against this baseline over time.  We believe this step is necessary to assure that regulations are working to protect public health, and provide the data necessary to fix them if they are not. 

No community should have to sacrifice public health or the quality of their environment for the sake of energy production.  Nor should artificial deadlines cut short efforts to get the regulations right.  New York Department of Environmental Conservation deserves praise for taking this necessary step.
