 ## European expenditure deciles
 
-Finally, we aggregated the data of 28 European countries with 5 income groups each into 10 European expenditure groups, to decompose the total European household energy and carbon footprint by European expenditure decile, ranking each national income group according to their mean consumption expenditure in PPS. We call these European expenditure deciles, although only countries with EUROSTAT data from 2005 to 2015 are included, which excludes Italy and Luxembourg, but includes the UK, Norway and Turkey. Data on decarbonization scenarios, especially final energy use, is from the IIASA scenario database [@riahi_shared_2017 @gea_gea_nodate], and work by Grubler et al. (2018) [@grubler_low_2018] and Millward-Hopkins et al. (2020) [@millward-hopkins_providing_2020].

 ## Units of analysis
 
 Our unit of analysis through the study is households per adult equivalent unit. This is the unit of analysis used in the EUROSTAT HBS when normalizing household size between income groups and countries, and we aimed to keep the results of our study within this framework: the first adult in the household is given a weight of 1.0, each adult thereafter 0.5, and each child 0.3 [@eurostat_description_2016]. 
 
-When we situate our results within decarbonisation scenarios, we adjust the total per capita results from the scenarios, to household per adult equivalence in order to better compare with our environmental footprint estimates. For example, we adjust a total final energy use of 53 GJ per capita from the LED scenario, first by the household share of the total European energy footprint in 2015 (around 0.62, calculated in EXIOBASE), and then the share of total adult equivalents in the total European population in 2015 (also around 0.62, calculated using the EUROSTAT HBS, number of households per country, and population data per country): a total final energy use of 53 GJ/capita is therefore adjusted to a household final energy use of 53 GJ/adult equivalence in Europe ((53 total GJ/capita * 0.62 household share of total footprint)/0.62 adult equivalent share of population = 53 household GJ/adult equivalence).

 As inequality measure through the study, we divide the value in the top European expenditure decile by that of the bottom European expenditure decile, a 10:10 ratio. For example, in expenditure, a 10:10 ratio of 5 means that adult equivalents in the top decile spend 5 times more on average than those in the bottom decile. All data and procedures are described in detail in the supplementary information (SI).
