Two studies released today in the journal of Environmental Science and Technology provide new insights into methane emissions from significant sources in the oil and natural gas sector and underscore the urgency of taking action to address pollution from these sources. The studies—focusing on the gathering and processing segment and the transmission and storage segment—were led by researchers at Colorado State and Carnegie Mellon universities and Aerodyne Research, and included collaboration with EDF and companies in each of these segments.
In the gathering and processing study, researchers measured 130 gathering and processing facilities, finding emissions at gathering facilities ranging from 0.6 to 600 standard cubic feet of methane leaking per minute (scf/m). For the transmission and storage study, a different team led by CSU also collected extensive on-site and downwind measurements of methane at 45 transmission and storage sites. Site-level methane measurements ranged from 2 to 880 scf/m, with an average measurement of 70 scf/m. Of all the facilities measured for these studies, data suggests the natural gas emitted was worth about $25 million and had the 20-year climate impact equal to the emissions of 2 million passenger vehicles.

Well, it didn’t take long before the Electric Reliability Council of Texas (ERCOT) released, at the request of Texas’ very political Public Utilities Commission, another report about the impacts of the Environmental Protection Agency’s (EPA’s) rules designed to protect public health.
This time ERCOT, which manages 90 percent of Texas’ electric grid, looked at the impact of seven EPA clean air safeguards on the electric grid, including the Cross State Air Pollution Rule (CSAPR), the Mercury Air Toxics Standard (MATS), the Regional Haze program (all of which go back before the Obama administration), the proposed Clean Power Plan, which would set the first-ever national limits on carbon pollution from existing power plants, and others. What was surprising to learn, though, is that after power companies in the state start complying with EPA’s other clean air protections, the proposed Clean Power Plan poses a minimal incremental impact to the power grid. We would only have to cut 200 megawatts of coal-fired generation, which equates to less than one coal-fired power plant. Read More
Nobody likes being told what to do.
Gina McCarthy, head of Environmental Protection Agency, knows that. So she asked her agency to craft a plan that leaves it up to states to shape their energy future – as long as they cut carbon emissions from power plants.
Often lost in the heated debate over EPA’s Clean Power Plan, however, is the fact this built-in flexibility will also give a boost to clean technology ventures, and speed up energy innovations already under way in many states. It could bring down costs for consumers, and maybe even give a much-needed boost to our economy.
Here’s how. Read More
Do you get a sense of déjà vu when you hear the fossil fuel industry arguments against the Environmental Protection Agency’s new climate change plan? You’re not imagining things – we’ve heard these many, many times before.
The EPA recently held public hearings around the country to solicit comments on its new proposal to put reasonable, nationwide limits on climate pollution from power plants.
The plan is moderate, flexible, and paves the way for considerable economic gains, but the substance hardly mattered for some die-hard opponents. The fossil fuel industry allies trotted out the same talking points about the supposed costs of action and American indifference to clean air policies that they always do.
Tellingly, industry lobbyists and their friends in Congress couldn’t even be bothered to wait and see what the rule said before blasting it with wildly inaccurate claims about the cost of implementation. Read More
A coal train rolls through a town in West Virginia, which produces more coal than any other state except for Wyoming.
Nobody was surprised to hear political foes of President Obama and leaders from several coal-dependent states blast EPA’s proposal to limit carbon pollution from America’s power plants.
The Clean Power Plan, released June 2, represents a big change in the way America will generate and use energy in the coming decades. We understand: Big changes are scary.
So it’s interesting to ponder which political leaders in states dependent on coal-fired power will, in the end, seize this historic opportunity.
Who will use the flexible policy tools offered in the Clean Power Plan to diversify their energy economies and unleash innovation to help their states grow? Who will show political courage? Read More

The bedrock legal authority underlying the U.S. Environmental Protection Agency’s (EPA) Clean Power Plan is broadly recognized — by our nation’s highest court, states, power companies, academic experts, and the EPA General Counsel serving during the President George H.W. Bush administration.
Our recent Climate 411 post chronicles the Supreme Court’s decisions affirming EPA’s authority to address carbon pollution from power plants under section 111 of the Clean Air Act.
In Massachusetts v. EPA (2007), the Court held that carbon dioxide is a pollutant under the Clean Air Act. Then, in AEP v. Connecticut (2011), the Court explicitly recognized EPA’s authority to limit emissions of carbon dioxide from power plants pursuant to section 111, and acknowledged the agency’s ongoing efforts to do so.
