Sales of the two most polluting fuels will be phased out in England to help cut air pollution, the government says.
Bags of logs sold in DIY stores, garden centres and petrol stations often contain wet wood – a type of wood which produces more pollution and smoke.
The public should move to “cleaner alternatives”, the government says.
Plans for the ban were first announced 18 months ago, but the Department for Environment, Food and Rural Affairs has now confirmed it is going ahead.
The government said wood burning stoves and coal fires are the largest source of fine particulate matter (PM2.5), small particles of air pollution which find their way into the body’s lungs and blood.
Particulate matter is one of several pollutants caused by industrial, domestic and traffic sources.
“Cosy open fires and wood-burning stoves are at the heart of many homes up and down the country,” said Environment Secretary George Eustice.
“But the use of certain fuels means that they are also the biggest source of the most harmful pollutant that is affecting people in the UK.”
The changes will mean:
- Sales of bagged traditional house coal will be phased out by February 2021, and the sale of loose coal direct to customers will end by 2023
- Sales of wet wood in small units (less than 2m3) will be phased out from February 2021. Wet wood in volumes greater than 2m3 will also have to be sold with advice on how to dry it before burning
- Makers of solid fuels will also need to show they have a very low sulphur content and only emit a small amount of smoke.
- It is not banning wood or coal burning stoves.
- The government set out its commitment to reducing emissions of PM2.5 alongside four other air pollutants, including ammonia and nitrogen oxides, in its 2019 Clean Air Strategy.
- Officials said the phase-out will give the public and suppliers time to use up stocks and move to cleaner alternatives, such as dry wood and manufactured solid fuels.
- These alternatives produce less smoke and pollution, and are cheaper and more efficient to burn, the government added.
What is wet and dry firewood?
- Wet – also known as green or unseasoned wood – is often sold in nets and is cheaper to buyIt contains moisture which, when burned, creates more smoke and harmful particles of air pollution (PM2.5) than dry wood.Wet wood can also damage chimneys much more, by allowing tar and soot to build up.
- Dry or seasoned wood – which has been dried out, often in a kiln – has a moisture content of 20% or less.
