Trees do most of the work creating oxygen and cleaning the air of gases like carbon dioxide in the spring and summer. Trees do produce VOCs, however, but do not produce NOx. Answer (1 of 3): The notion is that trees release water vapor. They sequester this carbon dioxide by storing it in their trunks, branches, leaves and roots; the best trees for carbon dioxide absorption will have large trunks and dense wood. The plants health, age and flowering state can also change the rate of this process. This occurs in plant leaves and uses carbon dioxide, water and light energy from the Sun to produce sugars that feed the plant, but also yield oxygen as a by-product. Dig a hole larger than the root system and fill the bottom with topsoil. Pine trees release more oxygen than any other tree species, making them a vital part of the global oxygen cycle.
