Urban household consumption contributes substantially to global greenhouse gases (GHGs) emissions. Urban household emissions encompass both direct and indirect emissions, with the former associated with the direct use of fossil fuels and the latter with the emissions embodied in the consumed goods and services. However, there is a lack of consistent and comprehensive datasets outlining in great detail emissions from urban household consumption. To bridge this data gap, we construct an emission inventory of urban household emissions for 52 major cities in Japan that covers around 500 emission categories. The dataset spans from January 2011 to December 2015 and contains 12,384 data records for direct emissions and 1,543,128 records for indirect emissions. Direct emission intensity is provided in g-CO/JPY to facilitate both future studies of household emission in Japan, as well as act as a reference for the development of detailed household emission inventories in other countries.
城市家庭消费对全球温室气体（GHGs）排放有重大贡献。城市家庭排放包括直接排放和间接排放，前者与化石燃料的直接使用有关，后者与所消耗的商品和服务所包含的排放有关。然而，目前缺乏详细概述城市家庭消费排放的一致和全面的数据集。为了弥补这一数据差距，我们构建了一个涵盖日本 52 个主要城市的城市家庭排放清单，涵盖了约 500 个排放类别。该数据集涵盖了 2011 年 1 月至 2015 年 12 月的数据，包含 12384 条直接排放记录和 1543128 条间接排放记录。直接排放强度以 g-CO/JPY 的形式提供，既方便了日本家庭排放的未来研究，也为其他国家制定详细的家庭排放清单提供了参考。
