Figure 8 is a stacked bar chart similar to Figure 7 but which shows how the CO2 equivalent greenhouse gas emissions per person differ for seven groups according to household size and composition. The seven groups include households with one person both under and over 60 years old; households with two or more people over 60; households with two adults, including one under 60; households with three or more adults; single parent households; and households with two or more adults and children. As in Figure 3.7 each bar also shows how the total emissions for that group break down into emissions from domestic energy and housing; food production and consumption; purchase and use of consumable goods; use of private services such as banking; and transport. The charts show that, in general, the smaller the household size the higher the emissions per person; that older people generate slightly higher emissions; and that adults tend to generate higher emissions than children.
