Top 10 green living myths – 7. What they tell you: Wood fires are green
What they don’t tell you: If you burn the wood in an open fire, the majority of the energy in the wood will be lost up the chimney.
Assuming it comes from properly managed forests, however, wood is a green fuel because the CO2 released when it gets burned will be sucked from the air by the trees planted to replace the felled ones. The inefficient burning typical in a fireplace also creates plenty of soot.
Like CO2, soot warms the atmosphere by absorbing heat from the sun – and it can also travel thousands of miles to settle on Arctic ice, where it accelerates melting by darkening the surface. A much better option environmentally is a log-burning stove.
These capture most of the heat from the fuel, greatly reducing the amount of wood required, and they slash soot emissions too. Some modern stoves are so clean-burning that they can even be used in smoke-free zones.
