How many processes does it take to remove carbon dioxide from air?

Removing carbon dioxide from the air typically involves multiple processes, depending on the method used. Common techniques include direct air capture, which employs chemical processes to absorb CO2, and natural methods like afforestation or soil carbon sequestration. Each method can involve several steps, such as capture, compression, and storage, or growth and maintenance in the case of natural approaches. Thus, the total number of processes can vary widely based on the chosen technology or strategy.
