Considering the great significance of residential sector for deep decarbonisation in the medium and long term, this study analyses the effectiveness of an emissions visualisation approach and economic incentives in promoting household low-carbon practices. The data was gathered by a questionnaire survey from 406 households in Hyogo Prefecture, Japan, which received eco-home diagnosis in the past three years. The result confirms that around 40% of the samples installed home energy management system (HEMS) as the visualisation tool, and many households received low-carbon subsidies; however, few of them have utilised the low-interest loan from the government of Hyogo. Household lifestyle efforts are less associated with the policy measures and some differ due to family characteristics, i.e., the age of head of the household. Replacing household equipment with low-carbon items is largely determined by the visualisation approach and availability of economic incentives. As an example, the installation of HEMS would increase the probability of replacement with an electric heat pump water heater by 25.6% and the introduction of solar PV system by 55.9%. This study assists in understanding household low-carbon practices and their relationship with the related policy measures.

考虑到住宅部门对中长期实现深度脱碳的重要意义，本研究分析了排放可视化方法和经济激励措施在促进家庭低碳实践方面的有效性。该数据是通过对日本兵库县406户家庭进行问卷调查而收集的，这些家庭在过去三年中接受了生态家庭诊断。结果证实，大约有40％的样本安装了家庭能源管理系统（HEMS）作为可视化工具，许多家庭获得了低碳补贴。但是，他们中很少有人利用兵库县政府提供的低息贷款。家庭生活方式的努力与政策措施的联系较少，并且由于家庭特征（即户主的年龄）而有所不同。用低碳物品代替家用设备很大程度上取决于可视化方法和经济激励措施的可用性。例如，安装HEMS可以将用电热泵热水器更换的可能性提高25.6％，将太阳能光伏系统引入的可能性提高55.9％。这项研究有助于了解家庭低碳做法及其与相关政策措施之间的关系。
