The U.S. Environmental Protection Agency’s (EPA) new Clean Power Plan will empower states to design customized, cost-effective programs to reduce climate-destabilizing pollution while ensuring continued electric system reliability.

States will be able to deploy flexible compliance mechanisms such as:

  • renewable energy
  • demand-side energy efficiency
  • shifts in utilization away from higher-emitting and towards lower-emitting generation sources
  • measures at specific plants to secure reductions in carbon pollution

And states will be able to do all of this while designing their compliance plans to make sure that generation resources are fully sufficient to ensure reliability. Read More »

In NJ Settlement, EDF Fights to Strengthen the State’s Energy Infrastructure

By Jukka Isokoski via Wikimedia Commons

The recent Energy Strong settlement between New Jersey regulators and Public Service Electric & Gas (PSE&G), the state’s largest utility, should help reinforce vulnerable energy infrastructure ahead of future severe storms. Last month, the Board of Public Utilities (BPU) agreed that customers could fund $1.2 billion in PSE&G improvements to New Jersey’s electric grid to make it more resilient and efficient. As a participant in the case, EDF was encouraged that PSE&G agreed to necessary changes to its grid to protect against more extreme weather events.

PSE&G, which had originally asked for $2.6 billion in storm-related hardening funds, submitted its Energy Strong proposal to regulators in the wake of Superstorm Sandy, which knocked out electricity for a third of homes and businesses in the state for weeks.

The BPU denied EDF and other environmental organizations full intervener status, preventing us from mounting a full case that would have included expert witnesses on proven climate science and the increased likelihood of future superstorms, the pressing need to take aggressive action to make our existing electric and gas distribution grids more resilient, and the need to transition to a smarter, more decentralized energy system.  Although our status in the case was limited by the BPU’s decision, we managed to argue for and win some positives for the environment: Read More »

Recruiting Tech Innovators to Find Climate Solutions

54097_Circuit Earth.JPGAmerica is in the midst of two booms: one in sensor technology and another in natural gas. Recent innovations—specifically advancements in drilling and hydraulic fracturing technologies—have dramatically increased the nation’s access to reserves of natural gas. While this influx of new technology has altered the energy industry, the resulting large-scale development has brought with it some real environmental and climate risks. Now is the time for the same ingenuity that transformed America’s energy landscape to help identify solutions to reduce the impacts caused by increasing supplies of natural gas.

Just this last month, two innovator programs were announced – one led by Environmental Defense Fund (EDF) and another from the U.S. Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E) – both are focused on developing new technologies capable of minimizing methane emissions from the natural gas supply chain. The programs are different but complementary and together signal there is  momentum building to engage the best and brightest innovators to help address a consequential component of the climate issue.

EDF Calls on BLM to Minimize Waste of Natural Gas on Federal Lands

This post was co-authored by Tomás Carbonell, EDF Attorney, and Brian Korpics, EDF Legal Fellow

NatlGasRigWetland_93178419_Photos-RF

Last Thursday, the Department of the Interior’s Bureau of Land Management (BLM) hosted a public forum in Washington, D.C. on venting and flaring of natural gas from oil and gas operations occurring on federal lands. This was the third in a series in which BLM received public comments on various options aimed at addressing the extensive and unnecessary loss of gas from onshore federal oil and gas leases. EDF is encouraged to see BLM taking on this vital issue, and we delivered testimony urging BLM to take strong and timely action to uphold its responsibility to minimize waste of our nation’s natural resources and ensure oil and gas development minimizes impacts to our climate and public health.

Reducing waste of natural gas on federal lands is a core element of the President’s strategy to reduce methane emissions, and for good reason. BLM is tasked with managing 700 million acres of federal lands – making it the largest single land management agency in the federal government – and it has broad responsibilities for the significant oil and gas resources located on those lands. Almost 40 million acres of BLM lands have already been leased for oil and gas production, accounting for approximately 14 percent of all onshore natural gas production and 8.5 percent of all onshore oil production in the United States.

Despite the scale of oil and gas production on federal lands, BLM’s policies covering venting, flaring, and other losses of natural gas are over three decades old. These obsolete regulations allow producers to waste significant amounts of natural gas that could be cost-effectively captured using today’s technology. The Government Accountability Office (GAO) found in 2010 that between 4.2 and 5 percent of all natural gas produced onshore on federal lands was vented, flared, or lost in fugitive emissions — enough gas to heat about 1.7 million homes each year.  A more recent study by the Western Values Project found that vented and flared methane could cost taxpayers nearly $800 million in coming years.

New Methane Study Demonstrates Urgent Need for Regulatory Action

36174_Colorado River.JPGIt has happened again. Another scientific study finds methane emissions from oil and gas production are higher than previously thought, reinforcing the urgent need to reduce emissions of this powerful climate pollutant. The latest study, accepted today to be published in American Geophysical Union’s Journal of Geophysical Research – Atmospheres, measured methane concentrations in the air over Colorado’s largest oil and gas producing region on two days during early 2012 and adds to our understanding of the environmental impact of oil and gas development.

The study—led by scientists from the National Oceanic and Atmospheric Administration (NOAA) and the Cooperative Institute for Research in Environmental Sciences (CIRES) at UC-Boulder—suggests between 2.6 and 5.6 percent of gas produced in the Denver Julesburg basin escapes into the air. That’s nearly three times the amount estimated using data from the Environmental Protection Agency’s Greenhouse Gas Reporting Program. The study also found emissions of smog-forming VOC emissions to be twice as high as estimated based on state data and emissions of benzene, a known carcinogen, to be seven times higher than current state estimates.

High Methane Emissions in PA Reinforce Need for Strong Regulation

NatlGasFlares_142558250_Photos-RFNearly every month, for the past six months, a new scientific study has been released that provides new insights in to where methane, a highly potent, climate-destabilizing greenhouse gas, could be reduced across the entire natural gas system – the next six months will be no different. But this week, a new joint Purdue-Cornell study published in the Proceedings of the National Academy of Sciences revealed high emissions from drilling.

Leading States Tackling Fugitive Emissions Problem Head-On

statesYou see something once, and it might just be an anomaly. See it twice, maybe coincidence. But when you see it a third time – that’s a pattern. A trend.

With Ohio’s move last week to control “fugitive” emissions from oil and gas operations, that’s what we’re seeing – a rapid trend from leading states to control this major source of air and climate pollution. The Ohio rules come on heels of similar actions in Wyoming and Colorado. Together, these rules signal a fast-growing recognition that fugitive emissions are a problem that has to be dealt with, and that there are cost-effective ways we can slash these emissions today.

A New Study Points to the Need for Improved Air Monitoring in Texas

Source: Dallas Observer

Source: Dallas Observer

A new study accepted for publication in Environmental Science & Technology takes a close look at the amount of certain air pollutants in the Barnett Shale, a booming oil and gas region in North Texas. Using public monitoring data from 2010-2011, researchers from the University of Texas at Austin compared air pollution levels measured at a monitor surrounded by oil and gas operations to the levels that would be expected based on available emission estimates. The result brings to light that the emissions inventory from the Texas Commission on Environmental Quality (TCEQ) for the Barnett Shale does not add up to the observations.

There are numerous air pollutants that can be emitted by oil and natural gas development. Depending on the local composition of the produced gas, emissions can often include volatile organic compounds (VOC, such as propane, butane, pentane, etc.) that contribute to the formation of ground-level ozone (also known as smog), and toxic air pollutants like benzene and hexane that are directly hazardous to human health. Methane, the primary ingredient in natural gas and a greenhouse gas catching lots of attention these days, is another powerful pollutant associated with these operations. Unlike the pollutants listed above, methane directly affects the health of our climate rather than human health. Fortunately, available technologies designed to capture methane are also effective in reducing these other pollutants. However, methane controls alone may not ensure that local air quality concerns are addressed – these require special attention. Read More »

Latest EPA Greenhouse Gas Inventory May Not Reflect Full Scope of Oil and Gas Emissions

david-lyon-287x377The Environmental Protection Agency recently released its draft inventory of annual U.S. greenhouse gas emissions. Reporting 2012 data, the inventory estimates methane emissions coming from natural gas and petroleum systems at around 7.6 million metric tons – that’s enough natural gas to provide energy to over 7 million homes annually. This new estimate when compared with last year’s report, which estimates emissions for the 2011 calendar year, shows overall methane emissions from natural gas and petroleum systems are 1.2 percent lower. Although this seems like good news, the new data is no cause for complacency, as it’s important to understand the cause of the changes which requires closer examination.

The draft inventory introduces some new methodological changes that reduce estimated emissions from previous years. The primary change was driven by the way EPA estimates emissions from gas well completions and workovers, the steps that follow hydraulic fracturing and clear liquids and sand from the well before production begins.

Science and Economics Agree: The Time is Right for California to Get Serious About Methane Pollution

Larissa-Koehler-200x300Recent numbers from the Intergovernmental Panel on Climate Change (IPCC) show that methane (CH4) is about 80 times more potent than carbon dioxide (CO2) in contributing to climate change over the first 20 years after it is released. Short-lived climate pollutants, like methane, are a large factor in determining how fast our climate will change over the next few decades.

These figures are particularly relevant in California where natural gas (which is about 99.9% methane) is used throughout the economy. For example, natural gas generates much of the state’s electricity through gas-fired power plants, is extensively used for home heating and cooking, and is increasingly being deployed as an alternative fuel for the state’s cars and trucks.

Yet, while California continues to operate and further build out a natural gas backbone in its energy economy, venting and leakage of uncombusted natural gas from pipes and machines can have an environmental impact. In fact, research shows that keeping methane leakage down to a minimum level is the only way to guarantee that the use of natural gas will provide immediate climate benefits, when switching from petroleum products.
