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.

Will Texas Step Up to the Plate on Energy Efficiency and Carbon Pollution Standards?

Coal-Plant-225x3001A couple of weeks ago, I wrote about energy efficiency and the Clean Air Act section 111(d) provisions in anticipation of the SPEER Second Annual Summit, a gathering of top energy efficiency industry leaders from Texas and Oklahoma. At the Summit, I co-led a session on Environmental Protection Agency’s (EPA’s) push to regulate power plant emissions. Session attendees agreed that Texas would be an unlikely leader in developing innovative ways to comply with carbon pollution standards for existing power plants.

This is a missed opportunity on Texas’ part, as states will get the first crack at drafting plans to comply with new federal standards. This is an important opportunity because individual states are in the best position to craft frameworks that enable maximum flexibility and are appropriately tailored to local circumstances. So, this begs the question: is there an alternative, more constructive path that is most beneficial to Texas? Read More »

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.

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.
