- Afforestation and Reforestation: Planting trees and other vegetation can sequester carbon dioxide from the atmosphere through photosynthesis.
- Biochar: Biochar is a type of charcoal produced from organic waste, such as agricultural or forestry residues. It can be used as a soil amendment to increase carbon sequestration in soil.
- Direct Air Capture (DAC): DAC technology captures carbon dioxide directly from the air and stores it in underground geologic formations, deep saline aquifers, or in mineral carbonates.
- Ocean Fertilization: Adding nutrients to the ocean surface can promote the growth of phytoplankton, which can absorb carbon dioxide from the atmosphere through photosynthesis.
- Enhanced Weathering: Crushed rocks, such as olivine, can be spread on land or in the ocean to accelerate the natural weathering process, which removes carbon dioxide from the atmosphere.
- Soil Carbon Sequestration: Changes in agricultural practices, such as reduced tillage and cover cropping, can increase carbon sequestration in soil.
- Blue Carbon: Wetlands, mangroves, and seagrasses can absorb carbon dioxide from the atmosphere and store it in the soil and biomass.
It’s important to note that while these products and technologies can remove carbon dioxide from the atmosphere, they should not be relied upon as a replacement for reducing greenhouse gas emissions at their source.
