Why Are Pennsylvania’s Oil & Gas Emissions Going Up?

By Andrew Williams / Published: August 22, 2016

NatlGasFlares_142558250_Photos-RF A new report reveals that harmful emissions from oil and gas development are increasing. This is bad news for Pennsylvania families who have been repeatedly told by industry trade groups that pollution is under control.

According to the Department of Environmental Protection, in 2014 oil and gas companies emitted nearly 110,000 tons of methane – a powerful climate pollutant that’s rapidly accelerating global warming. That represents an increase over the previous year. With 2016 on pace to be the warmest year ever recorded, we should be reducing methane emissions, not increasing them. Read More »

What the New NASA ‘Hot Spot’ Study Tells Us About Methane Leaks

Look up in New Mexico and on most days you’ll see the unmistakable blue skies that make the Southwest so unique.

But there’s also something hovering over the Four Corners that a naked eye can’t detect: A 2,500-square mile cloud of methane, the highest concentration of the heat-trapping pollution anywhere in the United States. The Delaware-sized hot-spot was first reported in a study two years ago.

At the time, researchers were confident the cloud was associated with fossil fuels, but unsure of the precise sources. Was it occurring naturally from the region’s coal beds or coming from a leaky oil and gas industry?

STUDY: A Closer Look at Urban Methane Pollution

By Steven Hamburg / Published: August 4, 2016

7174642172_60f5ed16e8_k The United States produces approximately 33 trillion cubic feet of natural gas each year. A majority of this gas is converted to electricity at power plants or used for industrial purposes, but about one third ends up making the journey from the well head, through underground pipelines, and into our homes and businesses. How much of this gas gets lost along the way—whether it’s through leaky equipment or other factors—is important because of the damaging climate impacts of methane pollution. And a new study published this week in Environmental Science and Technology is helping to expand our understanding of methane emissions in urban environments.

The study—a multi-year collaboration led by Washington State University and included researchers from Aerodyne, the National Institute of Standards and Technology, GHD, Purdue and Pennsylvania State universities—used a variety of techniques to measure the rate at which methane is lost to the atmosphere in Indianapolis, Indiana.

3 Keys for the American Petroleum Institute’s New Climate Task Force

By Ben Ratner / Published: July 21, 2016

The climate change discussion is percolating even in surprising places. The latest sign: the American Petroleum Institute’s recent formation of an internal task force on climate change. Reportedly the new task force’s mandate is to revisit API’s approach to this crucial issue, going into an election year and with ever greater scrutiny on fossil fuels.

It is too soon to know whether the task force will rubber stamp a business-as-usual approach defined by glossing over climate concerns and attacking policy measures, or chart a new path instead.

But if the task force is serious about a fresh look at the issue, here are three keys for the task force to consider as it ponders the future of API on climate. Read More »

Making Gas Pipelines Safer for Communities and the Climate

By Hillary Hull / Published: July 14, 2016

In response to the deadly natural gas explosion in San Bruno, California, the U.S. Pipeline and Hazardous Materials Safety Administration (PHMSA) is proposing new regulations to make pipelines safer. The regulations will go a long way toward safeguarding communities from the risks of natural gas explosions, but, if they’re done right, they could also protect the climate.

Natural gas is mostly methane – a potent climate pollutant, and reducing the amount of gas that leaks from pipelines also reduces emissions of methane. But there are aspects of the proposal that could result in an increase in methane emissions if proper action isn’t taken. The proposed safety measures require operators to conduct more testing to ensure that pipelines can handle high pressures of gas. Before this testing begins pipeline operators have to empty the pipes by blowing gas down the pipeline. Opponents to the rule say this would create a significant increase in methane emissions, but fortunately a recent study from a leading environmental consulting firm concluded otherwise. Read More »

3 Things to Know About Gas Pipeline Regulations

By Holly Pearen / Published: July 6, 2016

A ruptured natural gas pipeline in the quiet community of San Bruno, California ignited on the evening of September 9, 2010. The resulting fire destroyed 38 homes, killed eight people, and injured many others. It was one of the biggest pipeline explosions in recent history, and it very likely could have been prevented.

Now, almost six years later, the U.S. Pipeline and Hazardous Materials Safety Administration (PHMSA) is proposing new regulations to prevent serious incidents, like what happened in San Bruno, from happening again. Read More »
