A forest carbon sink refers to the process of forests absorbing carbon dioxide from the atmosphere and storing it in plants or the earth, so as to reduce its density in the air.

Compared with direct emissions reductions in industry, forest carbon sinks are a kind of indirect emissions reduction. They make little demand in investment and costs, but provide comprehensive benefits. Therefore, it's quite a practical and economical way to reduce emissions. Every hectare of forest is able to absorb between 20 and 40 tons of carbon dioxide.
