Research shows gathering pipelines in the Permian Basin leaking 14 times more methane than officials estimate

Methane emissions from natural gas gathering pipelines in the U.S. Permian Basin are at least 14 times greater than Environmental Protection Agency national inventory estimates, according to new peer-reviewed research from EDF, Stanford University and the University of Arizona. Gathering lines transport unprocessed gas from well sites to processing facilities and vary widely in size and pressure, with diameters ranging from two inches to as large as 30 inches. Methane is a potent greenhouse gas with over 84 times the warming potential of carbon dioxide over its first 20 years in the atmosphere, and this new research indicates the importance of finding and fixing pipeline methane leaks to mitigate the climate crisis.

New study finds flaring source of five times more pollution than previously thought

A new study out today in the journal Science finds that climate-warming methane emissions from flaring, the practice of burning off gas rather than capturing it for productive use, are five times higher than government estimates — primarily due to unlit and malfunctioning flares. Researchers conclude that flares are combusting at a 91% efficiency rate, significantly lower than the 98% efficiency rate that is assumed by operators and policymakers.

These findings confirm that our current environmental standards are not adequately controlling this pollution source and underline the need for urgent regulatory action from the Environmental Protection Agency  and Bureau of Land Management to limit pollution and waste from flaring.

INTERACTIVE MAP: Who is impacted most by overlooked pollution from America’s small oil and gas wells

A new EDF map is making it easier to access information about the communities across the country who are impacted by pollution from small oil and gas wells with leak-prone equipment.

There are over half a million wells across the country that are producing less than 15 barrels of oil and gas a day. But while they produce just 6% of the nation’s oil and gas, a new study reveals they are causing half of wellsite pollution nationwide.

Explore the map to learn more about your county.

This pollution has a very real impact on the climate and on the health of communities who live near these facilities. Not only do these facilities emit significant volumes of the potent greenhouse gas methane, they also leak other pollution that is toxic to human health and can severely deteriorate air quality.

Nearly 8 million people across the country live within half a mile of these well sites. A closer look at the data reveals that pollution from these wells has a disproportionate impact on many historically marginalized or vulnerable communities.

In wake of Supreme Court ruling, we must go full steam ahead to reduce methane pollution

The U.S. Supreme Court’s recent climate change ruling has unfortunately restricted the tools available to EPA in its effort to address climate pollution from power plants. However, it’s also important to recognize that the ruling in no way changed EPA’s longstanding authority and duty to address climate pollution under the Clean Air Act to address climate pollution itself — including from new cars and freight trucks, industrial sources, new and existing power plants, and oil and gas development.  And with respect to oil and gas pollution, this decision in no way impedes the agency’s ongoing and important efforts to reduce oil and gas methane pollution.

It remains critical that the EPA exercise its clear authority and obligation to move forward with protective climate standards, including its proposed rules to curb methane pollution from the oil and gas sector, which emits roughly 16 million tons of methane annually. Globally, methane from human sources is responsible for over a quarter of the warming we are experiencing today.

EPA’s authority to tackle methane pollution was reaffirmed by bipartisan majorities in Congress just last year, and the agency has commonsense, cost-effective tools at hand to address the health harms posed by oil and gas methane pollution, which in the U.S. alone has the near-term climate impact every year of 294 million passenger vehicles.

Creating data to support communities on the front lines of oil and gas production in the U.S.

By Jeremy Proville and Kate Roberts

This week we published a new study that combines locations of active oil and gas wells with census tract data in a way that helps us better understand the characteristics of the communities living near them. Our findings support what environmental justice groups have been voicing for years: in many counties across America, people who have been historically marginalized — communities of color, older Americans, children and people living under the federal poverty line — often live near wells in greater proportions than the other groups that make up the rest of their local county.

In addition to publishing these data with our study, we also used it to develop an interactive tool, which users can access to explore how each of 13 different demographic groups relate to oil and gas wells across all U.S. counties.

Rogue methane leaks from idle wells carry four big takeaways for policymakers

An ongoing methane leak involving several long-term idle wells in Southern California is raising safety concerns for nearby residents and highlights an important climate issue. Southern California has some of the worst air quality in the country, and leaks like these compound the negative impacts on some of the country’s most vulnerable populations. Both in California and across the country, many hundreds of thousands of end-of-life oil and gas wells are idle. That means that they are just sitting around awaiting proper site closure, which involves plugging the wells with cement to prevent gases or liquids from escaping and threatening the environment and public health.

Several such wells were recently found to be leaking methane — a powerful greenhouse gas that often escapes from oil and gas facilities alongside other toxic pollutants — in the Morningstar section of Bakersfield, CA. Local residents are concerned about the possibility of subsurface methane migration to homes and other structures in the vicinity.

While CalGEM and other agencies work to investigate and remediate the situation, four takeaways are already emerging:
