(2) what volume of carbon dioxide emissions was produced in the UK in the latest year for which figures are available; and what target in tonnes has been set for such emissions under the Kyoto protocol.
[holding answer 20 June 2008]: The main sources of carbon dioxide emissions (CO2) in the UK in 2006 were energy supply (40 per cent. of total UK CO2 emissions in 2006), transport (24 per cent.), business (17 per cent.) and residential (15 per cent.). The main sources of methane emissions (CH4) in the UK in 2006 were waste management (41 per cent. of total UK CH4 emissions in 2006) and agriculture (38 per cent.). The main sources of nitrous oxide (N2O) emissions in the UK in 2006 were agriculture (68 per cent. of total UK N2O emissions in 2006) and transport (15 per cent.). The primary source of Hydrofluorocarbons (HFCs) in the UK is release of refrigerants. The primary sources of Perfluorochemicals (PFCs) are from aluminium smelting and electronics manufacture. The primary sources of Sulphur hexafluoride (SF6) in the UK are from magnesium smelting and from the release of SF6 used in electrical insulation.
In 2006, emissions of UK carbon dioxide were 554.4 million tonnes. This figure includes emissions from the Crown Dependencies and those Overseas Territories that have joined the UK's ratification of the Kyoto protocol. This figure includes emissions and removals from land-use, land-use change and forestry, as accounted for under the Kyoto protocol. Our Kyoto target is to ensure emissions of the six greenhouse gases controlled under the protocol throughout the period 2008-12 are no higher than 3.412 billion tonnes of carbon dioxide equivalent. This equates to average emissions of no higher than 682.4 million tonnes of carbon dioxide equivalent per year. UK emissions in 2006 were 652.34 million tonnes carbon dioxide equivalent. This figure does not take into account additional emissions savings delivered through UK participation in the European Union Emissions Trading Scheme (EU ETS) which was estimated to be 34 million tonnes of carbon dioxide in 2006.
