China city-level emissions inventory, 2010

As the centre of human activity and being under the threat of climate change, cities are considered to be major components in the implementation of climate change mitigation and CO2 emission reduction strategies. Inventories of cities’ emissions serve as the foundation for the analysis of emissions characteristics and policymaking. China is the world’s top energy consumer and CO2 emitter, and it is facing great potential harm from climate change. Consequently, China is taking increasing responsibility in the fight against global climate change. Many energy/emissions control policies have been implemented in China, most of which are designed at the national level. However, cities are at different stages of industrialization and have distinct development pathways; they need specific control policies designed based on their current emissions characteristics. This study is the first to construct emissions inventories for 182 Chinese cities. The inventories are constructed using 17 fossil fuels and 47 socioeconomic sectors. These city-level emissions inventories have a scope and format consistent with China’s national/provincial inventories. Some socioeconomic data of the cities, such as GDP, population, industrial structures, are included in the datasets as well. The dataset provides transparent, accurate, complete, comparable, and verifiable data support for further city-level emissions studies and low-carbon/sustainable development policy design. The dataset also offers insights for other countries by providing an emissions accounting method with limited data.作为人类活动的核心载体且身处气候变化威胁之中，城市被视为气候变化减缓与二氧化碳（CO₂）减排战略实施的核心组成部分。城市排放清单是开展排放特征分析与政策制定的基础支撑。中国是全球第一大能源消费国与二氧化碳排放国，同时也面临着气候变化带来的巨大潜在危害，因此在全球气候变化应对中承担着日益重要的责任。中国已实施多项能源与排放管控政策，其中多数为国家级层面设计制定。然而，不同城市处于差异化的工业化阶段，且发展路径各具特色，因此需要基于自身当前排放特征制定针对性的管控政策。本研究首次构建了中国182座城市的排放清单，编制过程覆盖17种化石燃料与47个社会经济部门。本次构建的城市级排放清单在范围与格式上与中国国家级/省级排放清单保持一致。数据集同时收录了各城市的部分社会经济数据，例如地区生产总值（GDP）、人口规模、产业结构等。本数据集可为后续城市级排放研究以及低碳/可持续发展政策设计提供透明、精准、完整、可比且可验证的数据支撑。此外，本数据集通过提供一种基于有限数据的排放核算方法，可为其他国家提供参考思路。
