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.

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.

4 ways protective, greenhouse gas standards can benefit heavy-duty fleets

Fleet of green trucks

A paradox has become evident through many of my recent discussions and projects with fleets: 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.

New tool equips community voices to spur a just energy transition

Community Voices in Energy logo

Our new website, Community Voices in Energy — a collaboration with Chicago-based Blacks in Green — equips frontline communities to participate as experts in climate and energy proceedings and influence energy investments. By ensuring that community members are able to share their direct experience on the record in public utility commission hearings, the site helps utility regulators to make rulings that lead to a more equitable, healthy and affordable energy future.

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 50th 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.

Pennsylvanians want climate action; methane offers an opportunity for Gov. Shapiro to deliver

As we wrap up a summer of sweltering heat waves and dangerous air quality, new poll results show strong majorities of Pennsylvanians want action to address the climate crisis. The poll from EDF Action, Earthworks Action Fund, Sierra Club and Clean Air Task Force Action found that the majority of Pennsylvanians support one of the best ways to slow the current rate of warming — cutting methane pollution.

Methane from fossil fuel operations, agriculture and other industries is responsible for at least 30% of current warming.

With the U.S. EPA finalizing its nationwide methane rule for oil and gas producers this fall, Gov. Shapiro has the opportunity to give the majority of Pennsylvanians what they want by delivering a strong state implementation plan to reduce methane emissions.
