Aliso Canyon Disaster One Year Later: Some Progress, But More Action Needed

By Tim O'Connor / Published: October 21, 2016

When the gusher of methane pouring out of the Aliso Canyon natural gas storage field was discovered last October 23, it almost instantly transformed the sleepy Los Angeles suburb of Porter Ranch into the site of one of the biggest environmental disasters in recent history. It would ultimately take four months to stop the massive leak. According to a new report released today, it pumped nearly 100,000 tons of methane into the atmosphere.

Now, a year later, the question: What’s been done to fix the problem, and to prevent future blowouts – either at Aliso Canyon, or the 400 similar facilities in more than 30 states? The answer is, while there’s been some progress, it’s not nearly enough.

What would it mean for Los Angeles to go 100% renewable?

By Irene Burga / Published: October 20, 2016

10182500174_6070b2f074_kThe Los Angeles City Council recently passed a unanimous resolution requiring Los Angeles Department of Water and Power – the largest municipally-owned utility in the country — to study how the city can achieve a 100% clean energy future. With help from research partners, including academic institutions, the U.S. Department of Energy, and environmental and consumer groups, the study has the potential to become a foundational roadmap for running the utility on only clean and renewable energy.

California currently has a goal to reduce greenhouse gas emissions 40% below 1990 levels by 2030, with half of the state’s energy supply powered by renewable electricity by 2030. To achieve these targets, it is imperative for the state to look seriously at how to get off of fossil fuel dependency for our energy needs. Utilities and cities can be the key to reaching those climate goals. Read More »

Finding Industry Fingerprints on Atmospheric Methane

By Steven Hamburg / Published: October 7, 2016

fingerprint-imgWe’ve all seen TV detectives dust a scene for fingerprints. In a study in the journal Nature, a team of scientists did something similar, using carbon isotopes to identify the “fingerprints” of methane– one of the world’s most powerful climate pollutants in the atmosphere.

The study examined the isotopic signature from two types of methane emissions: biogenic (sources like wetlands, landfills and agriculture) and thermogenic (encompassing geologic seepage, activities associated with the oil and gas supply chain or coal mines).

The evidence suggests that not only are we significantly underestimating the share global methane emissions from thermogenic sources, we’re also underestimating how much comes from the production, delivery and use of oil and gas and the production of coal. Read More »

In Win for Environment, Court Recognizes Social Cost of Carbon

By Susanne Brooks / Published: August 29, 2016

Co-authored with Martha Roberts

If someone was tallying up all the benefits of energy efficiency programs, you’d want them to include reducing climate pollution, right? That’s just common sense.

Thankfully, that’s what our government does when it designs energy efficiency programs—as well as other policies that impact greenhouse gas emissions. And just this month, this approach got an important seal of approval: For the first time, a federal court upheld using the social cost of carbon to inform vital protections against the harmful impacts of climate change.

Smart Policies to Stop Disastrous Natural Gas Leaks

Infrared footage reveals massive methane emissions from a gas storage facility in California’s Aliso Canyon

Last fall, a massive leak from a natural gas storage facility in California’s Aliso Canyon released nearly 100,000 tons of methane pollution into the atmosphere — the largest uncombusted release of this potent greenhouse gas in U.S. history, and seen by many as the industry’s worst environmental disaster since the BP oil spill.

Facilities like Aliso Canyon inject gas pumped in from elsewhere and withdraw it when needed for electric production or heating. Aliso Canyon is the largest field of its kind west of the Mississippi River. There are around 400 such facilities across the U.S., about 14 in California. Until recently, regulatory oversight of these facilities has been uneven at best.

The exact cause of the Aliso Canyon incident is still being investigated, but all signs point to a problem in the aging, corroded casing of one of over a hundred individual wells at the sprawling site. Neither the utility’s maintenance programs nor the state’s lax enforcement of 1980s-era policies were sufficient to prevent this disaster. But now that’s about to change. Read More »

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

By Andrew Williams / Published: August 22, 2016

NatlGasFlares_142558250_Photos-RFA 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 »
