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 »

New York’s Con Edison to Take New Measures Protecting Against the Effects of Climate Change

The New York State Public Service Commission (Commission) took a historic step late last week, unanimously approving an Order that requires Con Edison to implement state-of-the-art measures to plan for and protect its electric, gas, and steam systems from the effects of climate change. This announcement regarding the future of New York State’s largest utility comes as a welcome coda to local storm recovery and resiliency efforts that have been in the works for some time now.

On October 29, 2012, Superstorm Sandy clobbered the coastline of New York City. Homes were swept away or badly damaged as corrosive salt water flooded basements, while millions lost power. In one of the enduring images of the storm, an exploding transformer at East 14th Street caused the “city that never sleeps” to go dark below 40th Street and stay that way for the better part of a week.

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.

Coloradans Overwhelmingly Voice Support for Proposed Air Regulations

Colorado is the quintessential swing state – with voters split about evenly between Republicans, Democrats and Independents.  That can make for some fractious politics at times, but our diversity is part of what makes us great.

What makes us even better is our unity – and that’s what we saw today when, by a margin of almost 10-to-1, Coloradans of all stripes called on the state’s Air Quality Control Commission (AQCC) to adopt new rules that would slash air and climate pollution coming from oil and gas development activities.

The AQCC opened its hearings on the proposed rules with a full day of citizen input, with people traveling from around the state (one drove six hours) to make their voices heard.  Residents from rural communities, including many from the Western Slope, stood up, one after another, to tell the AQCC Commissioners that the proposed rules should apply statewide and that the handful of local officials opposing the rules are out of step with the citizens they’re supposed to serve.  In response to those local officials, one citizen from Ridgway implored the Commission to protect all Colorado families and not “turn the West Slope into an air quality sacrifice zone.”

EDF couldn’t agree more.  Air quality in western parts of Colorado is trending in a bad direction, teetering on the edge of violating federal health standards.  The state health department issued nine ozone advisories last winter for Western Slope counties where oil and gas development is prevalent, meaning the air wasn’t healthy for kids, the elderly, active adults and people with respiratory illness.

Another Major Methane Study Shows Action is Needed Now to Reduce Emissions

Hamburg-228x300This commentary originally appeared on the EDF Voices Blog.

Mounting scientific evidence underscores the crucial importance of reducing methane emissions in the U.S. The latest study, published today in the journal Science, reviewed available data from the past 20 years and found that methane emissions from the U.S. natural gas supply chain are almost two times greater than current official estimates – flagging once again that methane emissions are a serious problem. However, the Stanford-led team also concluded that the current levels of methane leakage negates the climate benefit of switching to natural gas under some scenarios and not others, such as moving from coal-powered to natural gas electric generation.

As for what contributes to the higher than expected emissions, the study authors cited differing measurement techniques—including “bottom-up” direct measurement at the source, “top-down” readings from aircraft, and others—as well as the presence of “super-emitters” (a small number of sites or pieces of equipment producing a large share of emissions). Super-emitters are not easily sampled using most bottom-up direct measurement approaches. The team also spotlighted challenges associated with an increasingly ambiguous distinction between emissions from natural gas and oil production, both of which contribute methane to the atmosphere.

Meeting Retrofit Chicago’s Energy Goals: Three Key Constituencies

This commentary originally appeared on the EDF Climate Corps Blog.

ellen_bell287x377Following the lead of mayors and governors across the country, last month the President announced energy as a priority for the year. By focusing on energy management, organizations are contributing to the transformation of energy use in the country, saving billions in energy costs and cutting greenhouse gas emissions.

Mayor Rahm Emanuel’s Retrofit Chicago initiative, aimed at reducing participating buildings energy use in the city by 20 percent within the next five years, is a compelling example of this. For this reason, EDF Climate Corps, an innovative summer fellowship program that places specially trained graduate students in organizations to save energy and related costs, is working to recruit organizations in Chicago this month.

To ramp up energy savings in the area, EDF Climate Corps has already signed on AT&T, McDonald’s Corporation, Shorenstein Properties and Jones Lang LaSalle. Each summer, EDF Climate Corps fellows evaluate organizations for energy savings opportunities with many of them uncovering stakeholder engagement as a key savings opportunity.

After 400 EDF Climate Corps engagements, the program has found that there are three key constituencies to tap into for energy management:
