Carbon sequestration is the process
through which agricultural and forestry practices remove carbon
dioxide (CO2) from the atmosphere. The term “sinks”
is also used to describe agricultural and forestry lands that absorb
CO2, the most important global warming gas emitted by
human activities. Agricultural and forestry practices can also release
CO2 and other greenhouse gases to the atmosphere.
Sequestration activities can help prevent global climate change
by enhancing carbon storage in trees and soils, preserving existing
tree and soil carbon, and by reducing emissions of CO2,
methane (CH4) and nitrous oxide (N2O).
For more information on the science, emissions, and reduction
opportunities for these and other non-CO2 gases, please visit
