When wood burns in a stove, only as much CO₂ is released as the tree has removed from the environment in the course of its life. Burnt wood only emits as much CO₂ as would have been produced by natural decay in the forest.
Forests must be thinned regularly. The healthiest trees are given enough space and light, while diseased and overgrown trees are removed. The resulting wood is unsuitable as furniture or construction timber, but predestined for use as firewood.
If trunk and raw wood are harvested for material use, tops and branches can only be used for energy. In addition, there are considerable amounts of firewood that accrue in landscaping and in the maintenance of private gardens.
If this abundant reservoir of residual wood were not used for energy, it would rot and the CO₂ bound in it would be released back into the atmosphere as it decomposed. Heating with wood is therefore absolutely CO₂-neutral!
But as with all combustion processes, emissions are produced. We are driven by experience, research and modern technology to minimise these emissions. We want to build the cleanest wood-burning stoves in the world - so that the environment can benefit from the positive climate effect of wood combustion without endangering the purity of the air. Read here why our stove "fleet" is already twice as clean as required by law.
