Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, with reference to his Department's consultation on cleaner domestic burning of solid fuels and wood in England, what different types of PM2.5s released when burning (a) smokeless briquettes, (b) wet wood, (c) dried wood and (d) house coal on open domestic fires in England his Department is assessing; and if he will make a statement.

Our assessments of emissions of pollutants from domestic combustion sources use a range of data which are based on established international reporting. These use different conversion factors for different fuels but do not distinguish between different types of PM2.5.
