Wood burning: sustainable and clean?
As a renewable fuel, wood can be a good alternative to heating with oil, gas and coal. But stoves and boilers have to become substantially cleaner. In Europe, residential burning is the biggest source of harmful substances such as particulate matter and soot. Especially stoves and other single-room appliances are often operated improperly and wood is frequently used in a very inefficient way. Therefore, they contribute disproportionately to overall emissions.
