Methane controls mean cleaner air on the Navajo Nation

By EDF Blogs / Published: June 4, 2021

Policy action at both the tribal and federal levels this spring is creating promising momentum for cutting down on methane pollution on the Navajo Nation and across the Colorado Plateau, a step in the right direction for tackling climate change. Reducing methane waste would also improve public health and bring much-needed revenue to tribal and state governments.

In late April 2021, the Senate voted to restore an Obama-era U.S. Environmental Protection Agency rule to regulate methane emissions from oil and gas drilling. The Trump administration had previously rolled back this rule and eliminated federal requirements that oil and gas companies detect and fix methane leaks from their operations.

Navajo Nation President Jonathan Nez, Sens. Kyrsten Sinema and Mark Kelly from Arizona; Sens. Martin Heinrich and Ben Ray Luján from New Mexico; and Sens. Michael Bennet and John Hickenlooper from Colorado, all voted in favor of moving toward reinstating those important requirements.

4 opportunities for gas utilities to accelerate the energy transition today

By Natalie Karas / Published: May 17, 2021

A troubling story recently emerged about a group of gas utilities whose mission is to fight electrification. While the leaked materials alone don’t explain the full extent of the group’s efforts, it was unsettling to see baseless, fear-driven tactics such as “take advantage of power outage fear,” to make people wary of electrification. Instead of blocking progress to safe, affordable, clean energy, gas utilities concerned with the future should be taking steps today to accelerate the energy transition.

Several analyses make clear that electrification of commercial and residential buildings will play a predominant role in achieving state climate goals. Take New Jersey, for example, where residential and commercial buildings account for the second largest share of the state’s greenhouse gas emissions. According to modeling done by the state, in order to achieve its climate goals of 80% emission reductions by 2050, residential and commercial sector emissions must be reduced by 89%.

To achieve this level of emission reductions, New Jersey has found that “policies requiring net-zero emissions for new construction must be paired with aggressive requirements for electrification of older residential and commercial buildings as soon as practicable.” In other words, the last thing we should be doing is fighting efforts to electrify.

Maximizing the historic job creation opportunity waiting in our nation’s old and leaking oil and gas wells

By Adam Peltz / Published: May 5, 2021

After over 150 years of boom and bust oil and gas development, there are over a million inactive, unplugged oil and gas wells across the country. A new study published in the journal Elementa describes how, when not properly plugged, these wells can contaminate groundwater and emit methane as well as harmful chemicals into the atmosphere that endanger the economy and public health in communities where they are found. It also provides suggestions for how to maximize the environmental benefits of efforts to plug these wells.

There are 57,000 documented “orphan” wells across the country, meaning they have no owner of record, at least not one that’s still in business, and hundreds of thousands more orphan wells that are not documented. State, federal and tribal governments are left with the responsibility of plugging these wells – some of which have been abandoned for decades.

New innovative tool empowers utilities to reduce emissions in investment planning

By EDF Blogs / Published: May 3, 2021

By Erin Murphy and Christie Hicks

As the United States moves toward decarbonization, cities and states must use all means available to reduce climate pollution, and natural gas utilities should be at the forefront of this rapid energy transition. Gas utilities are the subject of increasing scrutiny because plans to expand and fortify their infrastructure could lock in greenhouse gas emissions and costs for decades. As the industry reckons with its role in a decarbonized future, advocates, utilities and regulators alike are calling for a carefully-managed transition that avoids costly long-term investments. New York has been at the forefront of this effort, seeking to balance ambitious climate goals with outdated natural gas investment planning processes.

To help utility planners align business decisions with environmental targets, EDF engaged MJ Bradley and Associates to develop the Gas Company Climate Planning Tool, an innovative new framework for New York and other states.

Cutting methane emissions from natural gas gives EU global climate leverage

By Kristina Mohlin / Published: April 7, 2021

Policymakers around the world increasingly recognize that along with carbon dioxide, cutting emissions of methane is critical for reaching the temperature goal of the Paris Agreement. Methane is a key element in the reinvigorated U.S. climate strategy and — for the first time — discussed in China’s latest five-year plan.

Now the EU has a chance to significantly influence methane emission reductions not only within Europe, but globally.

Methane from human activities is responsible for at least 25% of today’s warming. One of the largest emitters is the oil and gas industry. The European Commission Methane Strategy released last October identifies the global oil and gas sector as the most cost-effective opportunity for methane emission reductions.

The key to the EU’s global methane leverage lies in the continent’s vast gas market. A new policy brief by the Florence School of Regulation and Environmental Defense Fund describes policy pathways to unlock the opportunity, while a separate analysis prepared for EDF by Germany’s Enervis Energy Advisors illustrates how a comprehensive policy could offer far-reaching climate benefits.

Annular pressure monitoring and testing makes for safer wells

By Adam Peltz / Published: April 6, 2021

There are nearly a million active oil and gas wells in the United States, and if not correctly designed and maintained, they can leak harmful substances that will irreversibly pollute our land, air and water.

A new study published in the Proceedings of the National Academy of Sciences looked at data from over 100,000 wells and estimates that at least 14% experienced some loss of integrity, which could indicate a leak.

The study’s authors were able to determine the functionality and health of these wells based on data collected from annular pressure tests. In fact, the study analyzed almost 500,000 pressure tests conducted across three different basins — one of the largest studies of well integrity conducted to date.
