Does a tree produce more oxygen than carbon it absorbs?

    Yes! A tree produces, on average, about 260 pounds of oxygen each year and absorbs about 48 pounds of carbon dioxide. Of course this depends on the type of tree and its location. It is said that a single tree can produce enough oxygen in a year to support two people! Pretty cool.

    That depends on the tree’s oxygen production rate and its carbon sequestration rate. According to the EPA’s website (, the latter is dependent on factors like the species of tree, regional climate, the type of soil, and so on. Mature trees are also much more effective at sequestering carbon than saplings.

    Another website asserts that one mature tree is capable of absorbing carbon dioxide at a rate of 48 lbs./year. Canada’s environmental agency says that one tree produces almost 260 lbs. of oxygen in a year on average. If you take these figures to be accurate, then one tree produces much more oxygen than carbon it absorbs.
