Socioeconomic distribution of emissions and resource use in Ireland

This paper aims to determine emissions polluted directly and indirectly by an average person, for each household type, across a wide range of emissions. There are five household type categories: location, income decile, household composition, size and number of disabled residents. Ireland's Sustainable Development Model (ISus) is used which allows the analysis of direct and indirect sources of pollution per household as the model is based on an input–output methodology. Four sets of results are presented: first for greenhouse gas emissions, second for air pollutants, third for persistent organic pollutants and lastly for metals. An analysis section shows how the picture changes when one controls for the size and income of households. All results analysed are for the year 2006. Most greenhouse gas and metal emissions are polluted via indirect means, although direct sources of emissions play a role for CO2, SO2 and CO. The results suggest that the richest decile is the biggest emitter and poorer and larger households are seen to emit the least per person. It is also shown that household income has a stronger relationship with pollution than household size per person.

► We examine distributional differences in many emissions by household type.
► Most greenhouse gas and metal emissions are emitted via indirect means.
► Households in the highest income decile emit most per person.
► Targeting direct emissions will often be more regressive than indirect emissions.
