A study published today in Environmental Science & Technology confirms official figures from the Environmental Protection Agency showing that an enormous amount of methane – about 80 billion cubic feet per year – is escaping from thousands of key nodes along the nation’s natural gas interstate pipeline system. This equals the 20-year climate impact of 33 coal-fired power plants and more than $240 million worth of wasted natural gas per year, enough to meet the yearly heating and cooking needs of over a million U.S. households.

The study also shows the limitations of voluntary measures to address the industry’s methane problem. Companies that volunteered for this study, for example, reported emissions 30 percent lower than companies that were not involved. For some equipment, the difference was more than seven-fold. The performance gap between volunteer and non-volunteer companies reinforces doubt about industry claims that it can manage methane emissions on its own, underscoring the need for standards that create a level playing field across the sector.

Major Challenge, Big Opportunity

The study also confirms that major emission sources are widely distributed, intermittent, and unpredictable. In this case, a relatively small number of large leaks from ill-performing equipment and facilities accounted for 40 percent of the methane leaking from the country’s pipeline transmission and storage infrastructure.

The Environmental Protection Agency (EPA) is soon expected to propose its new “enhanced” Natural Gas STAR program, providing guidelines for oil and gas companies that want to voluntarily work to reduce their methane emissions. Calls for voluntary measures by industry to address this pollution have increased in recent months, as the EPA is set to release its  first-ever methane rules this summer.

While voluntary efforts can be helpful in establishing new technologies or practices, and validating industry’s ability to meet regulatory benchmarks, opt-in programs alone are no substitute for effective regulation that will reduce energy waste and better protect public health. As we’ve said before, current voluntary programs have an extremely low rate of company participation.

In fact, EPA’s current Natural Gas STAR membership includes less than one half of one percent of all oil and gas producers and operators. Therefore, any update to the program should be seen as an adjunct to long-overdue rules that set sensible emission limits for the industry. That’s the only way to set a level playing field for the approximately 10,000 operators that are part of this rapidly expanding oil and gas industry. Read More »

Methane emissions from vast oil and gas operations in the densely populated Barnett Shale region of Texas are 50 percent higher than estimates based on the Environmental Protection Agency’s (EPA) greenhouse gas inventory, according to a series of 11 new papers published today in Environmental Science & Technology.

The majority of these emissions are from a small but widespread number of sources across the region’s oil and gas supply chain. These emissions come from the sort of leaks and equipment malfunctions that are relatively easy to prevent with proper and frequent monitoring and repair practices.

The sprawling Barnett region, fanning out westward from the cities of Dallas and Fort Worth, contains about 30,000 oil and gas wells, 275 compressor stations, and 40 processing plants. It is one of the country’s largest production areas, responsible for 7 percent of total U.S. natural gas output.

Last Friday, the incoming head of the International Energy Agency (IEA), Faith Birol, provided a briefing to U.S. stakeholders about IEA’s new special report on climate change, which found that global emissions could peak by the end of this decade without reducing economic growth. The report outlines five key pillars for turning the emissions corner by 2020, and importantly, one of the pillars is reducing methane from the oil and gas sector. The report‘s finding that the scale of potential reductions from oil and gas methane is about the same as the reductions from renewable energy underscores the impact that action on methane can have.

IEA’s report is the latest in a stream of recent analyses illustrating the enormous potential for methane reductions to slow climate change. This is because methane has such a powerful short-term impact on the climate, with 84 times more warming power than carbon dioxide over a 20-year timeline. And, the report also highlights the significant opportunity that exists in implementing cost-effective, commonsense measures to cut these emissions, which many governments and companies have not yet taken advantage of.

California public school teachers. Religious charities. New York police officers and firefighters.

What do all of these groups have in common? Investors representing them — who manage $1.5 trillion in retirees, current employees’, and others assets – are standing together and calling for strong rules limiting harmful methane emissions from the oil and gas sector. This level of outpouring – from diversified investors with holdings in the oil and gas industry – represents five times the support investors expressed for methane rules last year. A trend is emerging.

The investors, including the largest retirement funds in California and New York, issued a powerful statement in support of the president’s methane proposal aimed at cutting emissions nearly in half in a decade. A centerpiece is regulation of methane, the primary ingredient in natural gas, which has over 80 times the warming power of carbon dioxide in the first 20 years after it’s released and is responsible for 25 percent of the warming we are feeling today.
