To ask the Secretary of State for Environment, Food and Rural Affairs, what estimate his Department has made of the amount of carbon dioxide emissions in grams per tonne of (a) coal, (b) wet wood, (c) kiln dried or seasoned wood and (d) oil for household use burned at home.
The data is provided as grams per kilogram (rather than grams per tonne) due to the scale of the data. It should be noted that harvested wood for bioenergy is considered to be carbon neutral, with the carbon dioxide (CO2) absorbed as young trees grow compensating for that released by burning.
The CO2 emissions in grams per kilogram of fuel used are:
(a) Household coal: 683g/kg
(b) Wet Wood: 0g/kg
(c) Dry wood: 0g/kg
(d) Oil for households (referred to as 'burning oil’ in the National Atmospheric Emissions Inventory): 859g/kg
