Because of a process called carbon sequestration, switchgrass harvested for biofuel is actually carbon negative.

Question

Quizplus · Accepted Answer

Carbon sequestration refers to the process of capturing and storing carbon dioxide from the atmosphere, which can help reduce greenhouse gas emissions. Switchgrass, as a plant, naturally sequesters carbon as it grows. When harvested for biofuel, the carbon that would have been released into the atmosphere during decomposition is instead stored in the biofuel and in the byproducts of the biofuel production process. This makes switchgrass biofuel carbon negative, meaning that it results in a net reduction in atmospheric carbon dioxide levels.
