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.

自2016年6月至11月，HOPE团队在法国的Aix Communauté-de-Pays、德国的曼海姆、挪威的卑尔根以及瑞典的乌梅亚四个城市对309户家庭进行了访谈。受访家庭被要求对四个二氧化碳排放领域（以CO2e计）的气候变化缓解措施进行评估：食品与回收、住房、交通及其他消费。这些缓解措施通过行动卡的形式呈现，行动卡不仅描述了缓解措施，还包含三项额外信息。首先，告知家庭实施该措施后每年可节约多少千克二氧化碳当量；其次，告知家庭实施该措施后每月可节省或支出的欧元/克朗金额；第三，一半的家庭获得了关于缓解措施对家庭健康影响的信息。对于每个家庭，二氧化碳减排量和财务成本或节省均进行了单独计算。这是可能的，因为家庭在访谈员展示行动卡之前，已在网上填写了一份关于其消费习惯、收入和支出的详细问卷（Herrmann等人，2017年第5页）。在线问卷被用于个性化行动卡，并在访谈前计算家庭的碳足迹。完整的描述可参考Herrmann等人，2017年。
