The total CO2 emissions in the UK are 9.84 tonnes per person per year, of which the components are:

Primary demand (million toe) [36] Per person (MWh) MWh to tonnes CO2 CO2 (tonnes)
Natural gas 92.7 17.79 0.185 3.29
Petroleum (excl non-energy use) 78.1 14.99 0.245 3.67
Coal 46.5 8.92 0.322 2.87
Total 9.84


Electricity generation is from:

Fuel used (million toe) [36] Per person (MWh) MWh to tonnes CO2 CO2 (tonnes)
Coal 35.9 6.89 0.322 2.22
Gas 26.6 5.10 0.185 0.94
Total 3.16


Fuel use after conversion:

Fuel used (million toe) [36] Per person (MWh) MWh to tonnes CO2 CO2 (tonnes)
Natural gas 66.1 12.69 0.185 2.35
Petroleum 78.1 14.99 0.245 3.67
Coal 10.6 2.03 0.322 0.66
Electricity 3.16
Total 9.84

Grand total 13.41





UK population mid-2006 was 60.6 million [source 26]

The average household size in 2003-4 was 2.4 people [42].




Electricity generation was 399 Terawatt-hours

Abbreviations and conversions


KWh: Kilowatt hour
Mt: million tonnnes
MWh: Megawatt hour = 1000 KWh
toe: tonnes oil equivalent

Carbon to CO2: multiply by 3.67 (via atomic weights of 12 and 16)

Net versus Gross Calorific Value

The Act On CO2 calculator uses Net CV factors rather than Gross [14]
