Why using ammonia in power generation is risky for the climate

Companies are announcing plans to use ammonia to decarbonize the power sector, because they view it as a carbon-free fuel that does not emit carbon dioxide and other carbon-based air pollutants, such as carbon monoxide, when combusted.

But there are serious issues with this strategy, primarily because it doesn’t take ammonia production — which often requires fossil fuels — into account. Depending on how it is made, using ammonia for power generation can increase greenhouse gas emissions and be incompatible with temperature targets. And, even when production is clean, co-firing ammonia can be expensive, dangerous and worsen air quality.

Zero-emission trucks are taking center stage at MCE 2023. Here’s what you should know.

By Jason Mathers / Published: October 11, 2023

As hundreds of fleet professionals from across the U.S. gather in Austin, TX this week for the American Trucking Association’s annual Management Conference and Exhibition, some may be arriving with a feeling of uncertainty about the pace of transition to zero-emission trucks.

While fleet managers have more tools at their disposal than ever before, the ambition of their efforts has grown significantly, too. Thus, it can feel as challenging as ever to make progress on reducing pollution from trucks at a pace that meets the urgent health and climate imperative we all face.

Fleets know they need to drive toward a zero-emission future. Yet, there is no one-size-fits-all pace, and there are as many paths as there are fleets. But long-term, performance-based medium and heavy-duty emission standards can help.

The commitment goes on: MARPOL’s 50th anniversary and EDF’s multi-disciplinary approach to shipping decarbonization

Today marks the celebration of World Maritime Day. This year’s theme — ‘MARPOL at 50 — Our commitment goes on’. This theme spotlights the 50^th anniversary of the International Convention for the Prevention of Pollution from Ships, and encourages discussions on the next phase of the International Maritime Organization’s work to promote a just transition to sustainable shipping.

The MARPOL Convention was adopted in response to a series of tanker accidents in 1976 and 1977 that caused millions of gallons of fuels to spill into our oceans. Since 1973, MARPOL has evolved into a fundamental aspect of the international framework for protecting oceans, and today, it covers the prevention of pollution from ships to the marine environment.

In keeping with the theme of Maritime World Day, Environmental Defense Fund is reflecting on its global shipping work one year into its consultative status at the IMO. Through engagement, collaboration and an array of scientific research, EDF has been a strong proponent of ambitious decarbonization targets, and of implementing solutions to achieve those targets in an equitable and just manner. The organization also advocates for specific mandates to adopt alternative means of propulsion and non-fossil-based fuels for the shipping sector to contribute to limiting global temperature increase to 1.5 degrees Celsius, compared to pre-industrial levels, in alignment with the Paris Agreement.

Interim Solutions needed while New York Public Service Commission moves forward on longer term truck charging infrastructure programs

By EDF Blogs / Published: September 7, 2023

By Pamela MacDougall and Cole Jermyn

UPDATE: Since the publication of this blog post on April 27, 2023, the New York Public Service Commission has made meaningful progress within its new Medium- and Heavy-Duty Electric Vehicle Charging Infrastructure proceeding. The PSC accepted comments on its initial questions from several dozen parties including EDF, and technical conferences are expected this fall. Despite this, the proceeding will likely continue into next year, leaving many early adopter fleets without sufficient access to charging infrastructure and potentially setting the state behind on its electrification goals. With deadlines from the Advanced Clean Trucks rule and emissions reductions goals from the Climate Leadership and Community Protection Act rapidly approaching, now is the time to kickstart the deployment of truck and bus charging infrastructure in New York. The state must implement interim solutions while the PSC continues to move forward. Primarily, changes can be made to the medium- and heavy-duty make-ready pilot program by expanding its eligibility to be more accessible to different types of fleets, depot owners and repair shops. Additionally, the program’s budget can be expanded, as the Commission’s Staff has already proposed. The Commission must also work with its sister agencies including the New York State Energy Research and Development Authority and the Department of Transportation to support near-term deployments of charging infrastructure. Not only will these solutions help provide the charging infrastructure that fleets need now, but the PSC will have the learnings it needs to have a full-scale medium- and heavy-duty charging program in the future. Environmental Defense Fund commends the PSC for the progress made so far on the proceeding and is looking forward to working with the commission to ensure no time is wasted in deploying necessary charging infrastructure improvements.

New bipartisan legislation would give U.S. orphan well management efforts a huge boost

By EDF Blogs / Published: August 7, 2023

Senator John Hickenlooper (D-CO) meets with oil industry and environmental group leaders at kick-off event for orphan well remediation program in Adams County, CO

By Adam Peltz and Meg Coleman

Across the country, a million or more orphaned oil and gas wells threaten the climate, public health, groundwater and surface waters and hamper local economic development. Help is on the way thanks to a major federal effort to invest $4.7 billion in closing orphan wells under the Revive Economic Growth and Reclaim Orphaned Wells Act as part of the Bipartisan Infrastructure Law, but the scale of the problem is vast.

In order to get a handle on these orphaned wells, New Mexico Sen. Ben Ray Luján , Democrat, and North Dakota Sen. Kevin Cramer, Republican, worked together to secure well closure funding in BIL. Now, they have reintroduced the Abandoned Well Remediation Research and Development Act and a bipartisan group in the House led by Pennsylvania Rep. Summer Lee, Democrat, and republican Oklahoma Rep. Stephanie Bice have introduced a companion bill. This important, bipartisan legislation would invest more than $150 million over the next five years to help find an estimated 800,000 undocumented orphan wells, reuse those we can for beneficial purposes and ultimately close all of the rest more effectively and affordably. While partisan politics seem to divide the Capitol these days, it is exciting to see leaders on both sides of the aisle come together to address orphan wells.

New rules could mean less waste, less pollution and more jobs for Louisiana

By EDF Blogs / Published: July 31, 2023

By Adam Peltz and Elizabeth Lieberknecht

Recently, Louisiana, under the leadership of Gov. John Bel Edwards, became the latest state taking action to curb pollution and waste from oil and gas production. In a new proposal, the state says it will limit natural gas venting and flaring and attempt to reduce the risk of thousands of idle wells becoming orphaned. Both actions will help create jobs, protect taxpayers and safeguard the environment. Here’s how.
