Social groups and CO2 emissions in Spanish households

This paper examines the social factors that underlie the composition of final demand and, therefore, determine the final volume of emissions. The study throws light on the relationships between the parameters characterising Spanish households (income, urban/rural residence, local population density, head of household's level of education and social class) and their behaviour with regard to consumption and the demand for goods and services. On this basis, we determine which consumption patterns are best aligned with sustainable growth and development. Our main conclusion is that the factors analysed determine the volume of emissions for each household in terms of their correlation with income, which is the primary determinant of consumption patterns. The methodology proposed combines linear SAM models and econometric estimation of emissions elasticity with respect to spending.

► The methodology proposed combines linear SAM models and econometric estimation.
► Social factors determine the volume of emissions for each household.
► This is due to their correlation with income, which determine consumption patterns.
► Higher levels of spending do not entail greater household emission intensities.
► Elasticities of emissions calculated are lower than one.
