A tree uses sunlight to convert carbon dioxide (CO2), water and nutrients into the compounds that form wood cells. During this growth process, the tree extracts CO2 from the air and releases oxygen. When the tree dies or is burned, the CO2 is released and in turn is taken up by young trees that need it for their growth, creating a sustainable exchange of carbon. This makes the choice of wood over fossil fuels a more responsible choice.

A well-built fire needs less wood, offers higher heating efficiency and minimizes particulate emissions. In addition, always light your fire using the "Swiss method".
