To ask the Secretary of State for Environment, Food and Rural Affairs what estimate he has made of the amount of (a) large particulates (PM10), (b) small particulates (PM2.5) and (c) nitrogen dioxide emitted to air in the UK by (i) domestic biomass generation of heat and (ii) biomass for power generation in each of the next five years; and what proportion of the annual national inventory of the respective emissions these represent.
Projections of emissions have been made based on the National Atmospheric Emissions Inventory released in December 2012 and the Department of Energy and Climate Change’s energy projections published in October 2013 for the year 2015.
The emissions from domestic combustion in 2015 and their share of national total emissions are estimated to be: (a) for large particles (PM10), 10.1 thousand tonnes and 8.0%; (b) for small particles (PM2.5), 7.2 thousand tonnes and 9.8%; (c) for nitrogen oxides, 0.97 thousand tonnes and 0.087%.
The emissions from power generation in 2015 and their share of national total emissions are estimated to be: (a) for large particles (PM10), 0.022 thousand tonnes and 0.017%; (b) for small particles (PM2.5), 0.011 thousand tonnes and 0.015%; (c) for nitrogen oxides, 1.5 thousand tonnes and 0.13%.
Emissions of nitrogen dioxide have not been separately estimated from those of nitrogen oxides.
