This figure is a pie chart; a type of graph in which a circle is divided into sectors, like the slices of a pie, where each slice represents a proportion of the whole. This pie chart shows the percentage breakdown of the total carbon emissions that arise directly from the direct energy using actions of an average UK inhabitant. The breakdown is as follows. The biggest slice is for space (or room) heating at 30 per cent of the total; the second slice is 29 per cent for personal car travel; then 12 per cent for holiday air travel; 11 per cent for water heating; 9 per cent for appliances such as fridges and tvs; 4 per cent for lighting; 3 per cent for cooking; and 2 per cent for other travel. The total adds up to 100 per cent.
