By Pedro Piris-Cabezas and Glenda Chen Airport activity emits a noxious cocktail of air pollutants, including ashy particulate matter, sulfur oxides, carbon dioxide, carbon monoxide, volatile organic compounds, hydrocarbons and nitrogen oxides. Among them, PM emissions from aircraft turbines often fly under the radar yet have an outsized impact on regional air quality and public …

EDF and IAC leading a study to understand the financial, soil and animal health impacts of regenerative agriculture practices on Native farming.

By Nini Gu Data recently collected by EDF’s MethaneAIR project in 2023 reveals a striking difference in the emissions profiles between the two major Colorado basins: the Denver-Julesburg (D-J) in the east, and the Piceance in the west. The D-J Basin exhibited a 1.7% methane loss rate from the total natural gas produced; by contrast,

By Pedro Piris-Cabezas and Glenda Chen The adoption of electricity-based synthetic fuels, also known as e-fuels, will be essential for any hard-to-decarbonize sector with a stake in a resilient liquid fuels market. Chief among them is aviation. E-fuels offer promising new routes nearing commercialization. However, a primary barrier to adoption has been the current cost …

Groundbreaking new data finds that leveraging synergies between the transport and power sectors could slash the cost of aviation e-fuels by half

For the first time, a satellite can deliver a full picture of oil & gas methane emissions over wide areas currently unseen by other instruments.

Environmental Defense Fund announced the expansion of Air Tracker—its cutting-edge air quality monitoring tool—to Rio de Janeiro today.

On November 1, the North Carolina Utilities Commission issued an order in the Carbon Plan docket, almost two months ahead of schedule. It largely ratifies an agreement reached by Duke Energy and the state’s Public Staff, who are charged with protecting the state’s ratepayers. While the Commission drops the requirement for Duke Energy to model …

By Neda Deylami Adopting the Advanced Clean Trucks rule and transitioning Illinois’ trucks from diesel engines to zero-emission motors is one of the most powerful opportunities to reduce climate and air pollution, spark economic growth, prioritize equitable outcomes and improve health in the state.  A new study from EDF and Atlas Public Policy modeled the …

By Michael Zimmerman and Neda Deylami  The market for electric medium- and heavy-duty vehicles in the U.S. is rapidly expanding. As of October 2024, 11 states have adopted the Advanced Clean Trucks rule, which requires manufacturers to produce increasing amounts of zero-emission MHDVs, and more are considering adopting this standard. Key policies like the ACT …

EDF retained Atlas Public Policy to model, for 18 states plus the District of Columbia, the number of charging stations that would be needed in each state to meet ACT targets through 2032.

Environmental Defense Fund unveiled a new map and analysis showing show the scale of dangerous methane pollution from landfills across the U.S.

New peer-reviewed analysis by Environmental Defense Fund (EDF), published by Science, reveals that millions of acres of critical wetland habitat have lost vital protections in the wake of a 2023 Supreme Court of the United States majority opinion (Sackett v EPA) that drastically narrowed the scope of wetlands protected under the Clean Water Act.

By: Poppy Brittingham Open ocean aquaculture (also referred to as “offshore” aquaculture) is a nascent industry in the United States. As it exists now, the industry has the potential to positively contribute to domestic seafood supplies if executed well. However, if the risks and impacts of the farms are not well understood, it can cause …

A new report from Environmental Defense Fund provides critical insights into species that may be optimal for farming in open ocean environments.

The oceans are a massive carbon sink. Researchers, companies and governments are exploring whether we can engineer coastal and ocean systems to store even more carbon. But while the ocean presents us with great possibilities, it’s also a complex system where human interventions can impact everything from the ecological (species’ interactions or the habitats they …

There are at least a million dead and forgotten oil and natural gas wells dotting the American landscape, many leaking methane and other toxic chemicals into the air and water, long after their productive days are over. In Pennsylvania alone, there are an estimated 300,000 to 700,000 — and estimated is the key word. The …

We’ve come to our final blog in our series on sustainable aquaculture for EDFish. Now that we’ve covered aquaculture feed, escapes, and diseases, we’ll wrap up the discussion with a look at technology’s role in sustainable aquaculture. With appropriate investment and incentives, ocean farming technologies and innovations could address sustainability risks for farming seafood in …

High-integrity carbon credits will require improved measurement, reporting and verification for livestock methane, and stronger environmental and social pr

A new report commissioned by EDF finds that blending hydrogen into the existing natural gas pipeline system would achieve limited greenhouse gas reductions and could continue New York’s reliance on natural gas beyond 2050.

By Anna Lóránt and Léa Pilsner The EU is finalising its Delegated Act on Low Carbon Fuels, a critical piece of its hydrogen policy. This is more than just a low-stakes technical step. If done right, it could significantly advance the EU’s decarbonisation agenda, showing the ‘Green Deal in action’. The details matter because this …
