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

By EDF Blogs / Published: October 4, 2022

Methane plume detected on a gathering pipeline during 2021 survey.

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

By Jon Goldstein / Published: September 30, 2022

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.

4 main takeaways from America’s top transit agencies on electrifying buses

By Pamela MacDougall / Published: July 28, 2022

Many U.S. transit agencies, from New York to Los Angeles to Houston, are working to convert their bus fleets from diesel to electric. The number of electric transit buses currently on order or operating in the U.S. grew 112% from 2018 to 2021, according to CALSTART. Electric buses are cleaner, quieter and increasingly more cost-effective than traditional diesel-powered alternatives.

While many makes and models of electric buses are now available to address transit agencies’ needs, charging is still a significant hurdle. Transit agencies are faced with the complexity of determining charging infrastructure needs while maintaining operations and reducing costs, which can be a maze of decisions and obstacles to overcome.

To uncover the emerging trends, barriers and best practices these agencies are implementing to meet their own electrification goals, EDF worked with Atlas Public Policy to interview 28 transit agencies in the process of electrifying their fleets, as well as utilities, engineering firms, charging manufacturers and thought leaders in transit charging. The results are highlighted in a new report out today entitled, Deploying Charging Infrastructure for Electric Transit Buses: Best practices and lessons learned from deployments to date.

Multi-state “action plan” on zero-emission trucks, buses is robust, but key additions are needed

By Larissa Koehler / Published: June 3, 2022

Last month truck manufacturers, environmentalists and others shared their thoughts on a multi-state draft action plan to spur zero emission medium- and heavy-duty trucks in 17 states, the Province of Quebec and Washington D.C.

The plan, spearheaded by the Northeast States for Coordinated Air Use Management and developed by signatory states, was the culmination of months of educational webinars and stakeholder outreach and demonstrated the fruits of that labor. It was comprehensive and reflected the inclusion of a diverse array of perspectives and ideas.

The model action plan could be further strengthened to provide a roadmap for states that adequately addresses the climate and health imperative created by diesel trucks and buses. Read More »

For Colorado’s clean truck ambition, it’s time for action, not delay

By Larissa Koehler / Published: April 20, 2022

In March 2022, Colorado Gov. Jared Polis unveiled an ambitious and forward-thinking zero-emission medium- and heavy-duty truck strategy his administration said could reduce climate emissions from this sector at least 45% by 2050.

Gov. Polis is right: Colorado’s Clean Truck Strategy would build upon the state’s “national-leading climate and infrastructure goals.” But key pieces necessary to achieve that ambition have already stalled. Three state agencies (Colorado Energy Office, Department of Transportation, Air Pollution Control Division) want to push adoption of the Advanced Clean Trucks rule and the Heavy-Duty Omnibus (low NOx) rule — key policy drivers for this transition — to next year.

In response, EDF and a host of other environmental groups, environmental justice advocates and local governments filed a petition with the state’s Air Quality Control Commission to move forward with the ACT and low NOx rulemaking and adopt these regulations this year, rather than delay to 2023, and AQCC agreed to hear the petition on April 21.

In short, the AQCC should work with the Polis administration to move forward with adopting the ACT and low NOx rulemaking by the end of the year.

This week, all eyes are on zero-emission trucks. It’s time for policymakers to go bold.

By Jason Mathers / Published: March 7, 2022

As leaders from government, business and tech meet this week at CERA Week, The Work Truck Show and the ATA Technology and Maintenance Council annual meeting, the growing availability of zero-emission trucks will be center stage.

The last five years have seen tremendous progress in the availability of and fleet interest in large, zero-emission vehicles. This electric truck revolution is being spurred by growing private sector investment, rapidly maturing technology and clear government leadership. As a result, these trucks are moving from the showroom floor to highways and local streets across North America.

Among the many signs of progress are:
