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.

Results and discussion of a multi-year nitrous oxide emissions measurement study conducted in semi-arid peninsular India.

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

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.

Climate change has been brought into sharp focus in recent years with intense weather events leading to food shortages, famine and the destruction of homes, businesses and infrastructure.
