Planting forests, changing forest management to retain more carbon, and adjusting agricultural practices to enhance soil carbon storage.Learn more
The cultivation of crops which take up carbon dioxide as they grow and are used to produce electricity, liquid fuels, and/or heat. The carbon dioxide generated is captured and sequestered underground.Learn more
Practices that increase the amount of carbon stored in living plants or sediments in tidal marshlands, seagrass beds, and other tidal or salt-water wetlands.Learn more
Filtering processes that capture carbon dioxide from ambient air and sequester it underground.Learn more
The use of reactive minerals (particularly mantle peridotite, basaltic lava, and other reactive rocks) to form chemical bonds with carbon dioxide.Learn more
Carbon dioxide captured through BECCS or direct air capture is injected into a geologic formation, such as a saline aquifer, where it remains in the pore space of the rock for a long time. This is not a negative emissions technology, but rather an option for the sequestration component of BECCS or direct air capture.Learn more
Scaling the capacity of negative emissions technologies to meet expected needs for carbon removal will require a concerted research effort to address the constraints that currently limit deployment. The research agenda proposed in this report addresses gaps in scientific and technical understanding, and research needed for bringing negative emissions technologies up to scale, including cost reductions, deployment, and monitoring and verification.
