A new, global hydrogen energy industry is poised to take off, attracting hundreds of billion of dollars in investments. However, hydrogen is an indirect greenhouse gas with a powerful near-term climate impact that is often overlooked. Scientists have raised concerns that hydrogen leaks could negate the expected climate benefits of using hydrogen energy. Real-world data on hydrogen emissions is lacking, but a groundbreaking new technology can help.

MethaneSAT will fill critical gaps in the capabilities of existing methane satellites and be a powerful tool to accelerate climate action.

New research from Environmental Defense Fund provides a high-level overview of how four technology fields can be valuable tools in agricultural operations and contribute to agroecological goals.

(NEW YORK, NY — March 6, 2023) A new study by climate scientists sheds light on the significant role food systems will play in future global warming and what can be done about it.

The technology that can help us quantify hydrogen emissions is just now being developed and demonstrated. Aerodyne Research Inc. in collaboration with EDF is unveiling a new instrument that for the first time allows for the quantification of hydrogen emissions across the value chain.

Forest carbon credits may prove to be a useful tool to reduce net carbon emissions from land use and supplement overall emissions reductions. New research from EDF refines previous research by accounting for more variability in ecological factors that affect carbon sequestration.

The extremely wet spring of 2019 caused 14.2 million acres of cropland to go unplanted in the Midwest. Farmers across the region had flooded fields that kept them from getting equipment onto the fields to plant their crops. This resulted in over $4 billion of prevent-plant crop insurance claims, which assists farmers when weather conditions …

Deep Dives is a new blog that will offer our readers in-depth scientific analyses, hard data, and practical policy prescriptions from Environmental Defense Fund’s (EDF) top environmental health experts. Our authors are specialists in air quality, chemistry, epidemiology, law, public health, and more. We will continue to offer information for broader audiences on EDF’s Safer …

New EDF research offers insights and opportunities for strengthening the integrity of California's temperate forest carbon credits by accounting for differences in forests' geography and tree species composition.

By Nathan Willse, Stony Brook University, and Harlisa Harlisa, Environmental Defense Fund Crustacean fisheries offer enormous opportunities as high-value and potentially resilient alternatives to over-exploited finfish stocks. However, rising global demand for crustacean products and rapid environmental change call for an increased focus on the sustainable management of crustacean stocks. While landings, the catch received …

By James France Many parts of the world are looking to liquefied natural gas to provide a pathway to a cleaner and more secure energy resource — interest that has only grown since Russia’s war on Ukraine has shaken global energy markets. Meanwhile, gas-producing countries see LNG as a critical growth opportunity. The question is …

As global populations grow and fish populations shift or even shrink, one thing is clear: offshore aquaculture in the United States is a matter of when not if. We talked to some experts to better understand what we know, what we need to know, and where we go from here.

Environmental Defense Fund's Ilissa Ocko evaluates ChatGPT's knowledge of climate change.

The Mississippi River Basin is sensitive to increased risks of flooding and poor water quality. However, natural infrastructure could help mitigate these risks. EDF research shows that wetlands and floodplains are the best natural resources to reduce flood risk and nitrate pollution.

A new study from EDF and Carbon Mapper offers insights into just how much climate pollution specific oil companies may be responsible for.

The first priority in fighting climate change is drastically reducing emissions of greenhouse gases, according to EDF's Chief Scientist.

Operators wasted over $500 million of gas, underscoring importance of strong rules from BLM and EPA to reduce emissions from practices like flaring

A recent poll, commissioned by EDF Action and conducted by Global Strategy Group, found broad support among majorities of Minnesotans for ambitious climate policies.

Water utilities are increasingly posting interactive maps online to help residents identify whether their homes are connected to lead service lines (LSLs). EDF's new blog series, Mapping Lead Pipes, will explore how utilities are approaching maps, evaluate which map features are most and least effective, and share best practices to help guide future efforts.

Last January, FBN and EDF launched the $25 million RAF pilot program and provided nearly 50 farmers with seasonal lines of credit of up to $5 million. EDF provides oversight related to the environmental criteria required for RAF eligibility. RAF will double in size to $50 million in operating lines for the coming season and anticipates originating up to $1 billion in climate-smart operating lines over the next five years.

Nitrogen is essential for life, but excess nitrogen can pollute the atmosphere and water. EDF's new N Balance Implementation Guide provides a road map for food and agriculture companies to help reduce nitrogen pollution from agricultural production and claim the environmental improvements associated with nitrogen management.

Last year, for the first time, EDF and McGill University mapped every existing documented orphan well across our country. Shortly after, Congress passed the Infrastructure and Investment Act, IIJA, which included $4.7 billion to document, plug and remediate orphan wells.  This new funding, secured through EDF’s leadership, provides federal support for the first time for …
