The Department of Environment, Food and Rural Affairs published the Government response to the consultation on cleaner domestic burning of solid fuels and wood on Friday 21 February. This consultation ran between August and October 2018.
Wood burning stoves and coal fires are the single largest source of the pollutant PM2.5 (fine particulate matter), emitting twice the contribution of industrial combustion and three times the contribution of road transport. This form of pollution consists of tiny particles which penetrate deeply into body tissues, including the lungs and blood. Long-term exposure can cause cardiovascular disease, strokes, asthma and lung cancer, shortening lifespans. It has been identified by the World Health Organisation (WHO) as the most serious air pollutant for human health. The WHO has stated that coal is a known carcinogen and strongly recommended against its use in domestic burning.
These proposals are in line with our clean air strategy, which sets out our strong commitment to achieve our national emissions ceiling targets. We have legally binding commitments to reach specified emissions ceilings for 2020 and 2030 for five key emissions—nitrous oxides (NOx), sulphur dioxide (S02), fine particulate matter (PM2.5), ammonia (NH3) and volatile organic compounds (VOCs). With domestic combustion identified as the single largest contributor of PM2.5 emissions, it is essential to make changes in this area to make progress towards achieving these emissions targets. This announcement comes after statistics released on 14 February showed the significant progress that the Government have made in tackling air pollution, with nitrogen oxide, sulphur dioxide, particulate matter, and non-methane volatile organic compounds all down significantly since 2010. However, the statistics also highlighted the impact of the increased popularity of domestic burning on PM2.5 pollution, emphasising the importance of these measures.
The consultation response sets out our intention to phase out the sale of house (bituminous) coal and wet wood for use in domestic burning to improve the health of millions by encouraging burners to use cleaner fuels. Wet wood is wood that has not been adequately seasoned and contains high levels of sap. Burning wet wood can result in at least twice the amount of smoke emissions than that produced when seasoned or dry wood is burned. When wet wood is burned, the heat output is significantly reduced, and chemicals build up on the inside of the stove and chimney, which increases the risk of chimney fires.
The accompanying impact assessment shows that the benefits accruing from the expected reduction in PM2.5 and sulphur dioxide from these proposals will reach in excess of £7 billion over the period 2020 to 2030, with the cost to business over the same time period being less than £125 million.
