With the continuous increase in carbon dioxide emissions due to human activities and the resulting severe climate issues, there is global concern about energy conservation and emission reduction. However, detailed data on energy consumption and emissions at a fine-grained scale, particularly regarding spatial dimensions and sector-specific emissions, remains insufficient and in need of refinement and timely updates. In Japan, following the Fukushima nuclear disaster, there has been a significant shift from nuclear power generation to reliance on fossil fuels across various sectors, highlighting disparities in emissions data across different regions and industries. Our work extends the emissions time series for Japan's 47 prefectures, incorporating their socioeconomic characteristics over a broader time frame and with a more detailed sectoral classification. The emissions inventory, covering the period from 1990 to 2020, is based on the consumption of the three main fossil fuels across 32 sectors, with emissions carefully allocated for regional power generation. This dataset, presented in a unified format, is expanded to include longer time scales and more detailed socioeconomic data. It is anticipated to offer crucial insights for establishing regional emission reduction targets and identifying sectoral priorities for decarbonization.
由于人类活动导致二氧化碳排放量不断增加，从而引发了严重的气候问题，全球都在关注节能减排。然而，在精细尺度上，特别是在空间维度和特定部门排放方面，有关能源消耗和排放的详细数据仍然不足，需要进一步细化和及时更新。在日本，福岛核灾难之后，各部门已从依赖核电转向依赖化石燃料，这突显了不同地区和行业之间排放数据的差异。我们的工作扩展了日本 47 个都道府县的排放时间序列，在更广泛的时间范围内并采用更详细的部门分类纳入了它们的社会经济特征。排放清单涵盖了 1990 年至 2020 年期间，基于 32 个部门的三种主要化石燃料的消费情况，并对区域发电进行了仔细的排放分配。该数据集以统一的格式呈现，并扩展到包括更长的时间尺度和更详细的社会经济数据。它有望为制定区域减排目标和确定脱碳的部门重点提供重要的见解。
