Forests are the lungs of our planet. This is due to the fact that every tree absorbs carbon dioxide from the air and transforms it into carbon which is then stored as one component of wood. Therefore wood, when burned, releases as much carbon dioxide as the tree has absorbed during its lifetime. That is why wood biomass – as opposed to fossil fuels like coal or oil – is called “carbon dioxide neutral” since the release and absorption of carbon dioxide constitutes a circle.
The natural carbon dioxide circle – Trees absorb carbon dioxide from the air. This gas goes back into the air when the tree rots or when the wood is burned in a Tulikivi fireplace. The circle starts again.
The US Environmental Protection Agency stated that the greenhouse effect could be reduced by using more fuels made from biomass.
