Carbon dioxide can be permanently stored under the seabed in geologic reservoirs.

Marine plants and algae, like phytoplankton, take up CO2 during photosynthesis, and this can increase the ocean’s uptake of atmospheric CO2.

This booklet from EDF and partners provides a primer on various ocean CDR strategies, summarizing the theory behind each technique, the current state of knowledge of their carbon storage potential and associated costs, technical readiness, and potential environmental and social impacts.

Ocean alkalinity enhancement (OAE), also termed enhanced weathering (EW), aims to alter seawater chemistry, usually by spreading finely ground alkaline minerals like silicates and carbonates in seawater or on coastal lands.

Macroalgae, or seaweeds, are large, plantlike organisms that grow naturally in the ocean and, like land plants, take up and store carbon via photosynthesis.

Electricity can be used to remove carbon dioxide from seawater by driving well-understood chemical reactions that either liberate carbon dioxide gas from the seawater for capture and sequestration, or alter seawater’s chemical balances to enable it to store more CO2 than it naturally would.

“Blue carbon” methods are a wide-ranging category of nature-based climate solutions that aim to preserve or enhance the ocean’s natural CO2 capture and storage capacity by protecting, restoring, or better managing specific ocean ecosystems.

Texans know better than to believe the lies. But, whenever severe weather strikes the state and the isolated electric grid is imperiled, they’re always fed them: “Green energy” is offered up as the ultimate scapegoat, facts be damned. Why doesn’t the Wall Street Journal editorial board know better? Last week, they ran a piece blaming …

A new partnership will work to reduce methane emissions from production of milk around the world.

This EDF report shares the results of a multi-year study conducted on five farms in India to measure nitrous oxide emissions from different nitrogen application rates in different cropping systems. It shows that carefully chosen alternative practices (with lower nitrogen rates) can achieve a triple win: farmers get similar or better yields, similar or higher profits, and must lower nitrous oxide emissions.

Learn how much carbon cropland soils can store by exploring two white papers from EDF.

As the U.S. works to stabilize the climate and foster innovative domestic industries, reducing emissions from agriculture — currently about 10% of annual emissions — is a critical piece of the puzzle. Yet federal R&D investments in agricultural climate solutions remain 35 times smaller than clean energy R&D investments. Of the limited agricultural R&D spending,

The biggest news is not what the bill contains and where dollars will flow, but how it will significantly change American attitudes towards climate.

We spoke with Natasha Vidangos, Senior Director for Climate Innovation and Technology at Environmental Defense Fund, about what’s next for the Infrastructure Investment and Jobs Act and how it can help us tackle the climate crisis.

The Inflation Reduction Act puts a nearly $370 billion down payment on clean energy and climate progress, making it the most significant climate action ever taken by Congress.

Here's the landmark climate progress you made possible

EDF scientist Tianyi Sun explains the opportunities and risks of hydrogen as a clean alternative to fossil fuels.

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 …

The Impact of Fossil Fuels on Communities of Color: Environmental Justice & Misinformation

The U.S. made an important commitment at COP27 yesterday that will help reduce climate and air pollution from the dirtiest vehicles on our roads and create a foundation for more ambitious action, which is urgently needed to reduce pollution from trucks and buses.

As Bad Actors spread false narratives, we can fight for the truth — starting with the Inflation Reduction Act, the most significant climate law Congress has ever passed.

After three years of actively collecting methane emissions data in the Permian Basin, EDF researchers have gained new insights that will make it easier to reduce emissions of the incredibly potent greenhouse gas methane.

Joint study released by Environmental Defense Fund (EDF), Lloyd’s Register (LR) and Ricardo PLC, examines the potential marine environmental impacts of ammonia spills during its use as a shipping fuel.

EDF report focused on non-operated joint ventures (NOJVs) in the oil and gas industry finds that supermajors’ climate targets to reduce methane emissions only apply to assets they operate directly.
