ENERGY IN THE CYCLE OF NATURE During growth, trees require CO2, which they take from the air and storage in the wood and leaves. When wood is burnt or decomposes, CO2 is released. Only as much CO2 is released as the tree absorbed from the atmosphere in the course of its growth. So if you heat with wood, you heat sustainably in the cycle of nature, i.e. it is CO2-neutral.
