Planting trees in tropical climates with wet seasons has another advantage. In such a setting, trees grow more quickly (fixing more carbon) because they can grow year-round. Trees in tropical climates have, on average, larger, brighter, and more abundant leaves than non-tropical climates.
The planting of trees on marginal crop and pasture lands helps to incorporate carbon from atmospheric CO 2 into biomass. [29] [30] For this carbon sequestration process to succeed the carbon must not return to the atmosphere from biomass burning or rotting when the trees die. [31] To this end, land allotted to the trees must not be converted to ...
[151] [152] Trees capture CO 2 while growing above ground and exuding larger amounts of carbon below ground. Trees contribute to the building of a soil carbon sponge. Carbon formed above ground is released as CO 2 immediately when wood is burned. If dead wood remains untouched, only some of the carbon returns to the atmosphere as decomposition ...
Within the carbon capture and storage approaches, carbon sequestration refers to the storage component. Artificial carbon storage technologies can be applied, such as gaseous storage in deep geological formations (including saline formations and exhausted gas fields), and solid storage by reaction of CO 2 with metal oxides to produce stable ...

A eucalyptus plantation in final stages at Arimalam.. The type of tree planted may have great influence on the environmental outcomes. It is often much more profitable to outside interests to plant fast-growing species, such as eucalyptus, casuarina or pine (e.g., Pinus radiata or Pinus caribaea), even though the environmental and biodiversity benefits of such monoculture plantations are not ...
This means trees from monoculture planting that do not survive never reach full potential for carbon sequestration to offset China's carbon output. Overall, there is a possibility for afforestation to balance carbon levels and aid carbon neutrality , but several challenges still remain which hinder an all encompassing effort.
IPCC estimates that land-use change (e.g. conversion of forest into agricultural land) contributes a net 1.6 ± 0.8 Gt carbon per year to the atmosphere. For comparison, the major source of CO 2, namely emissions from fossil fuel combustion and cement production, amount to 6.3 ± 0.6 Gt carbon per year. [15]
