Data for: What are necessary and sufficient conditions for household choices of climate mitigation actions? – An empirical study in four European countries
From June to November 2016 the HOPE-Team interviewed 309 households in four cities: Communauté-de-Pays-d’Aix (France), Mannheim (Germany), Bergen (Norway), and Umeå (Sweden). The households were asked to rate individual climate change mitigation actions in four sectors of CO2e-emissions: Food & Recycling, Housing, Mobility and Other Consumption. The climate change mitigation actions were presented on action cards. These action-cards described the mitigation actions and contained three additional pieces of information. First, it informed the household how much CO2 equivalents in kilogram per year the household could save, when implementing the measure. Second, it informed the household how much money in Euro/ Krona per months the household would save or spent, when implementing the measure. Third, half of the households received information on what effect the mitigation measure would have on the households’ health. The CO2e-savings and the financial costs or savings were calculated for each household individually. This was possible, because households had filled in a detailed questionnaire about their consumption habits, income and expenditure online, before they were visited by interviewers, who presented them with the action cards (Herrmann et al. 2017: 5). The online questionnaire was used to individualize the action cards and calculate the household’s carbon footprint before the interview. Full describtion can be found at Herrmann et al. 2017.
