What our climate goals mean for natural gas, and what states should do about it

By Natalie Karas / Bio / Published: January 13, 2021

The transition to a low-carbon economy will have a big impact on the way we think about natural gas: how we produce, use and transport it. One area where this challenge is particularly acute is the state regulatory frameworks governing gas utilities across the country, and in particular, how those rules line up against the climate goals now being set by a growing number of states.

States that don’t re-envision the way their gas utility systems run will be challenged to meet their climate targets. To help states avoid that fate, EDF has developed a new guide suggesting ways that state regulators can navigate this complex challenge.

Electrifying Texas’ successful emission reduction program

By John Hall / Bio / Published: December 18, 2020

A new Environmental Defense Fund analysis finds that Texas’ successful emission reduction program could be even more powerful if it went electric — not just for reducing smog-forming nitrogen oxides and other local air pollutants, but for cutting greenhouse gas emissions and sparking job growth in the burgeoning electric vehicle industry.

Administered by the Texas Commission on Environmental Quality, the Texas Emissions Reduction Plan provides financial incentives to reduce emissions from polluting vehicles and equipment. The bulk of TERP funding has been dedicated to quickening the replacement of larger diesel vehicles — medium- and heavy-duty vehicles. Since 2001, more than 35,000 TERP projects totaling over $1.3 billion in grants have reduced upwards of 183,000 tons of NOx, a major driver of the state’s air quality challenges.

Applying TERP’s annual grants to spur the electrification of Texas’ truck and bus fleets would decrease NOx emissions faster and for as little as one-third the cost per ton of NOx compared to TERP’s past grant programs.

The connection between jobs and addressing orphan oil and gas wells

By Elgie Holstein / Bio / Published: November 17, 2020

All across the country right now, there are tens of thousands of officially documented “orphan” oil and gas wells creating environmental hazards for their communities. These are wells that the oil and gas industry walked away from because they became uneconomic over time. Rather than properly sealing them, they left state and federal taxpayers holding the bag. These wells can be big sources of air, water and climate pollution if left unaddressed.

And this is just the tip of the iceberg. There are hundreds of thousands and perhaps millions more of these inactive, unplugged wells that need to be addressed. This is not to mention the potential for adding hundreds of thousands of currently active wells to the orphan well inventory as oil and gas producers struggle to survive the downturn in petroleum prices.

Luckily, efforts are underway in Congress and within the presidential transition plan to address these orphan wells. In his economic plan, President-elect Joe Biden laid out his vision for a cleaner and healthier future.

New report shows truck and bus manufacturers are readying for a zero-emission future

By Jason Mathers / Bio / Published: October 29, 2020

The North American truck and bus market is on the cusp of a zero-emission future. There is a clear and urgent need to drive down pollution from medium- and heavy-duty vehicles, which contribute to climate change and cause serious harm to human health. Companies, transit agencies and other organizations that operate large fleets understand this, and are moving swiftly to zero-emission alternatives. Manufacturers, recognizing the growing demand for zero-emission vehicles, are racing to bring more of these vehicles to market.

A new report from Environmental Defense Fund, The International Council on Clean Transportation and Propulsion Quebec demonstrates the magnitude of manufacturer investments. Race to zero: How manufacturers are positioned for zero-emission commercial trucks and buses in North America shows that every major truck and bus manufacturer is now developing at least one all-electric vehicle model or is part of an industry collaboration to bring zero-emission vehicles to market.

This growth in model availability demonstrates a marked change in an industry that, just a few years ago, had only a handful of zero-emission options on offer.

Another study reveals Permian methane levels are abnormally high, reinforcing need for action

By EDF Blogs / Bio / Published: October 19, 2020

By Jon Goldstein and David Lyon

A new peer-reviewed study published today once again confirms the Permian Basin has some of the leakiest oil and gas wells in the country.

For the study, researchers with the University of Wyoming used a mobile methane laboratory to quantify emissions from 46 randomly selected well pads in New Mexico and 25 in Texas. They found those sites are emitting between 5 to 9 times more methane pollution than The Environmental Protection Agency estimates suggest.

This granular look at well pad emissions is a critical part of understanding what is causing the emissions. Earlier this year, EDF used this data to estimate total methane emissions across New Mexico and concluded the state was likely emitting up to one million metric tons of methane per year.

When combined with other measurement techniques, we can get an even clearer sense of the entire region’s methane footprint. The satellite-based TROPOMI methane instrument, as well as aerial surveys conducted through our PermianMAP project — can detect emissions from other types of oil and gas equipment.

Two chemicals that remind us why we should exercise caution with the oil industry’s wastewater

By Cloelle Danforth / Bio / Published: October 14, 2020

Over the past few years, we’ve written a lot about the wastewater generated from oil and gas production — specifically, how little is known about what’s in it and the potential risks of exposure.

But as states try to set standards for how to safely treat and dispose of this waste, there are two chemicals in particular that deserve to be among the regulatory priorities.

The first is a class of synthetic chemicals known as per- and polyfluoroalkyl substances — PFAS for short. Members of this class, often referred to as “forever chemicals” because they are highly persistent in the environment, are known to cause adverse health impacts in humans. This can include a range of symptoms, including damage to the immune system, low infant birth weights and cancer.

The second chemical is 1,4-dioxane. Short-term exposure to this carcinogen can cause immediate health impacts, like eye, nose and throat irritation and impaired lung function. Prolonged exposure can lead to liver and kidney damage, as well as cancer.
