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.

Why America Needs Methane Policy

Methane policy

Recently, the White House took a crucial stride to tackle methane pollution and natural gas waste. A key aspect of the strategy tasks the U.S. Environmental Protection Agency (EPA) with enacting policy to reduce emissions from the oil and gas industry. Yesterday, EPA formally initiated its process, issuing five white papers focused on the biggest opportunities to cut the industry’s methane emissions. A final decision for action is expected later this year.

The Administration’s strategy to reduce methane emissions is an urgently needed development to slow the rate of climate change in our lifetimes. That’s because methane is an incredibly powerful and climate-destabilizing greenhouse gas. Whether you’re a concerned citizen who wants better protections from pollution, an individual compelled to see the U.S. do more to defend the people and places most vulnerable to global climate change, or an energy watchdog who wants to minimize needless waste—know that solutions are within our grasp.

Let’s look at a key piece of the process that the White House galvanized and that EPA has now started to carry forward. EPA’s white papers provide thorough, technical assessment of oil and gas methane emission sources and mitigation technologies, and they provide the factual basis to support policy action. The process requests feedback from the public and a range of expert stakeholders that will help EPA answer:  Is now the time to create a real methane policy for oil and gas? I am optimistic the answer will be a resounding “YES.”

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.

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.

Practical Air Pollution Controls Even the Oil and Gas Industry Can't Deny

This commentary originally appeared on our EDF Voices blog.

methane_animation_still-1_0Everyone knows that if you want your kids to grow up strong and healthy, they need to eat their vegetables. But as any parent knows, it’s easier said than done. That’s why in my house, there is a rule: you can’t have any dessert until you eat your vegetables.

Now, of course, my kids like to argue with me and my wife about exactly how many vegetables they have to eat and whether they can reach into the fridge and select a different vegetable if they don’t like the one she or I cooked that night. That’s okay. We like to encourage creative problem solving. But there’s no getting around the rule. You must eat your vegetables.

As I see it, methane pollution from the oil and gas industry is a lot like kids and vegetables. Reducing it is good for them, but we have to have a rule that requires them to do it. Read More »

Final Order from NYPSC on Con Edison Rate Case Reveals Especially Encouraging Language on Climate Change Directives

In Tuesday’s blog post, we discussed the recently concluded Con Edison rate case, its context, and its significance in advancing clean energy and grid resilience in New York. Today, we take a closer look at the final Order posted last Friday by the New York State Public Service Commission (the Commission) to uncover some of the more encouraging outcomes buried in this 300+ page document:

  • Con Edison agreed to various measures that allow for more distributed generation, i.e. on-site power generation, such as combined heat and power, rather than relying solely on power generation and distribution from the traditional, centralized grid. For example, Con Edison agreed to pay for some fault current mitigation, which enables distributed generation to be connected to portions of Con Edison’s grid where it would otherwise be prohibited, and agreed to develop an implementation plan for a microgrid pilot. Additionally, Con Edison agreed to treat customer-sited projects, including distributed generation, as integral parts of its system by considering them in its 24-month planning horizon. Because some distributed generation can operate in an ‘islanded’ mode, or separate from the main grid, and can thus continue operating in a power outage, distributed generation can play a critical role in improving resilience.

Critical Decision Expected Tomorrow in Colorado on Clean Air Rule

Day 4 of the ongoing hearings on a groundbreaking proposal to reduce air and climate pollution from oil and gas operations in Colorado saw Team EDF pushing back on claims opposition groups have made to try to weaken the proposal.

Leading companies Noble, Anadarko, Encana and DCP also put on strong cases, using their own operational data to show the proposal is cost effective. They should be lauded for their leadership, as should local governments and conservation groups that brought strong analytics to the hearings.

If the proposal is adopted without being weakened, it will eliminate more than 90,000 tons of smog-forming VOCs annually (the same amount produced by all the cars and trucks in Colorado) and more than 100,000 tons of methane, a highly potent greenhouse gas.

COGA and CPA Fight Common-sense Methane Regulation

Dan GrossmanIndustry trade groups – the Colorado Oil and Gas Association (COGA) and the Colorado Petroleum Association (CPA) – came out swinging against methane regulation in the third day of hearings on a groundbreaking proposal to reduce air and climate pollution coming from oil and gas operations.

And some wild swinging it was!

They acknowledged that we need to reduce methane, a highly potent greenhouse gas. But they said studies are showing different results about how much methane is being leaked and vented and that we shouldn't regulate methane until we know exactly how much is escaping.

Arguments Heat Up in Colorado Air Rulemaking, But the Facts Remain

Yesterday, we covered the Colorado Air Quality Control Commission (AQCC) taking public testimony from citizens who traveled from around the state to speak in support of a groundbreaking proposal that would slash emissions of smog-forming pollutants and greenhouse gases coming from oil and gas activities.

Formal proceedings kicked off today – and will likely run through the weekend – with various parties presenting their opening cases. EDF went early in the day, providing strong evidence that the proposed rule is cost-effective and urgently needed to combat local air quality problems and climate change. We also highlighted some glaring flaws  in the methodology industry opponents cooked up to show inflated costs for the rules.

The Colorado Oil and Gas Association (COGA), the Colorado Petroleum Association (CPA) and the DGS group are throwing everything they can at the rule to try to gut it.  But they’re in a shrinking minority on the wrong side of history.
