Kwesi Joseph’s thesis is simple – crushed basalt rock mixed with soil and compost in this Brooklyn garden will both capture more carbon from the air and also help plants grow bigger, thus increasing the potential yield of fruits and vegetables.
To meet its climate goals, Britain must not only cut emissions, but also scrub carbon dioxide from the atmosphere. A new study finds that rock dust sprinkled on farmland could supply nearly half of the needed carbon removal.
Spreading rock dust on farmland could pull enough carbon dioxide from the atmosphere to remove about half of the amount of that greenhouse gas currently produced by Europe, according to a major study published Thursday in the journal Nature.
