  • Reducing agricultural methane emissions is essential to a climate-safe future with healthy, thriving communities. However, solutions that cut methane from agriculture but fail to also remedy harmful impacts to local communities’ health, air and water quality are insufficient.

  • Amicus Brief of Environmental Defense Fund

    Type: Case resources

    Date: February 2, 2023

    EDF filed this amicus brief to correct the record after we learned that our past statements on biogas were used — selectively and without our knowledge — in court filings and other venues to undercut the advocacy of peer and partner organizations seeking state government action to address community-level impacts. This misrepresentation of EDF’s position is not aligned with our views of the current situation or our values as an organization committed to strengthening people’s ability to thrive on a changing planet.

  • 2023 EDF Winter Special Report

    Type: Report

    Date: January 30, 2023

    As unprecedented drought torments the American West, Maurice Hall and his team are using science and forging partnerships to create a whole new approach to water management — one that can revitalize rivers and aquifers and share water more equitably.

  • Improving Water Planning in Texas

    Type: Report

    Date: January 23, 2023

    This report explains the process by which Texas Groundwater Conservation Districts (GCDs) have executed their statutorily required planning function to arrive at a Desired Future Condition (DFC) and the inextricable link that exists between DFC development and state water planning.

  • What Is Ocean Carbon Dioxide Removal?

    Type: Column/Article

    Date: January 18, 2023

    All future climate scenarios that hold planetary warming close to 1.5 °C by 2050 will require massive cuts in greenhouse gas emissions, supplemented by the use of carbon dioxide removal (CDR) methods to clean up leftover heat-trapping carbon dioxide (CO2) from the atmosphere.

  • Sub-seafloor Geologic Storage of Captured CO2

    Type: Column/Article

    Date: January 18, 2023

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

  • Ocean Fertilization

    Type: Column/Article

    Date: January 18, 2023

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

  • Ocean Carbon Dioxide Removal Methods

    Type: Column/Article

    Date: January 18, 2023

    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

    Type: Column/Article

    Date: January 18, 2023

    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.

  • Macroalgal Open-Ocean Mariculture and Sinking

    Type: Column/Article

    Date: January 18, 2023

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