Carbon removal or carbon capture
What is carbon removal? Carbon removal, also known as carbon dioxide removal (CDR) or carbon drawdown, is the process of capturing carbon dioxide (CO2) from the atmosphere and locking it away for decades or centuries in plants, soils, oceans, rocks, saline aquifers, depleted oil wells and other geological reservoirs, or long-lived products like cement. Scientists have proposed many different methods of carbon removal. Some of these are already in use at relatively small scales, whereas others remain in the early stages of research and development. Technologies and practices for implementing carbon removal are often called negative emissions technologies (NETs). Carbon removal is not the same as carbon capture Although they are often conflated, carbon removal is importantly different than fossil carbon capture and use or storage (fossil CCUS). Carbon capture and storage (CCS) captures CO2 from a smokestack or flue, such as in a gas-fired power plant or a cement factory, and then s...
