HC Deb 19 November 2002 vol 394 cc41-2W
Mr. Redwood

To ask the Secretary of State for Environment, Food and Rural Affairs what emissions of(a) carbon monoxide, (b) hydrocarbons, (c) oxides of nitrogen and (d) particulates are generated by the average UK oil central heating domestic boiler. [81012]

Alun Michael

We estimate that in 2000 there were approximately 760,000 households using oil for central heating in the UK, burning a total of 2.25 million tonnes of oil annually. Emissions from individual boilers vary depending on the amount of use, and their efficiency and maintenance. However, we estimate that average annual emissions per boiler in 2000 were as follows:

Pollutant Average annual emissions per boiler
Carbon Monoxide 0.49kg
Hydrocarbons1 1.3kg
Oxides of Nitrogen 6.5kg
Particles (PM 10) 0.09kg
1Hydrocarbons includes volatile organic compounds and methane
