Not only do Koppe stoves create a warm and cosy atmosphere, they are also more environmentally friendly thanks to more efficient and lower emission combustion engineering methods. Wood is a renewable source of energy and using it protects our climate. It releases only as much carbon dioxide as a tree would have absorbed during its period of growth. The transport routes are shorter if local wood is used. This not only reduces transport costs, but also means that less carbon dioxide emissions are produced during transportation.
