The only carbon dioxide released by simply cutting the tree is that which is produced by the energy required to cut the tree: the human breathing out carbon dioxide as he swings an axe or uses a saw, the carbon dioxide emitted by a chainsaw's combustion engine, or the carbon dioxide emitted by logging machinery while cutting the tree.
Significantly more carbon is emitted afterward as the lumber is transported from the site and as the tree is cut up into smaller pieces, then the smaller pieces are shipped all over. Finally, as the wood biodegrades (or burns), some carbon dioxide will be released.

The gas released during breathing is carbon dioxide. When we inhale, we take in oxygen and when we exhale, we release carbon dioxide, which is a waste product of the process of cellular respiration in our bodies.
Trees absorb carbon dioxide from the atmosphere during photosynthesis. When trees are cut down and not replaced, this carbon dioxide is no longer absorbed, leading to an increase in its levels in the atmosphere. Additionally, when trees are burnt or decompose, the stored carbon is released back into the atmosphere as carbon dioxide.
Carbon dioxide is released during the light reaction.
During respiration, carbon dioxide gas is released as a byproduct of cellular metabolism. This occurs during the process of breaking down glucose to produce energy in the form of ATP. Carbon dioxide is then exhaled out of the body through the lungs when we breathe.

Carbon dioxide is released during the light reaction.
Carbon dioxide is released from the bloodstream into the alveoli in the lungs, to be exhaled during expiration.
When you exhale, carbon dioxide is released into the atmosphere.
