数据集使用建议 在使用2018年中国环境扩展投入产出（CEEIO）数据集时，用户需注意几项关键的单位调整和数据范围。经济值单位已由“10,000人民币”更改为“1人民币”，并根据ILCD的标准化单位需求，根据人民币：欧元=7.5:1的汇率，将数值归一化为”欧元EUR“单位，而质量单位则从“吨”调整为“千克”。该数据集覆盖了44种环境压力类型中的28种，因此在使用时需注意哪些环境类别被包含及可能的遗漏。为了更好地理解和应用这些数据，建议用户细致阅读随数据集的数据来源文件，了解其编制方法和假设。此外，建议将这些数据以系统化的方式融入更广泛的环境分析或决策过程，以确保分析的准确性和一致性。
产品或过程的技术目的 CEEIO数据库以2018年为基准年，为在中国生产的每1人民币单位的视听设备提供全面的环境影响评估。 这些LCA数据对视听设备制造行业的各方利益相关者至关重要，包括政策制定者、环境学家和企业。 它使他们能够了解与这类设备生产相关的环境负担，并制定减轻这些影响的策略。 数据库旨在为可持续材料选择、生产过程优化和环境政策制定提供信息。 此外，它还可以用来帮助设计生态标签计划，或在该行业内的不同产品或公司之间进行环境绩效比较。

关于数据集的一般性意见 CEEIO 是清华大学徐明教授与广东工业大学梁赛教授和南昌大学田曦教授合作，利用环境扩展投入产出模型研究中国环境问题的近十年研究成果。CEEIO 由中国政府统计机构发布的基准经济投入产出表和从多个来源编制的环境卫星账户组成。CEEIO 的开发得到了清华大学 Kenneth G. Lieberthal 和 Richard H. Rogel 中国研究中心的部分支持。

技术代表性
技术说明，包括后台系统 根据现有数据，CEEIO数据集考虑了中国各个部门和家庭产生的四大类中44种环境压力： (1) 淡水消耗；(2) 23 种大气污染物，包括二氧化碳（CO2）、甲烷（CH4）、一氧化二氮（N2O）、氮氧化物（NOx）、粉尘和烟尘、二氧化硫（SO2）、有害微量元素（HTEs，包括汞、砷、硒、铅、镉、铬、镍、锑、锰、钴、铜和锌）、空气动力学直径为 2. 5毫米或以下的颗粒物（PM2.5）、空气动力直径为10毫米或以下的颗粒物（PM10）、一氧化碳（CO）、挥发性有机化合物（VOC）、氨（NH3）； (3) 13 种水污染物，包括化学需氧量、氨氮化合物、磷、石油污染物、挥发性酚、氰化物、水生汞、水生镉、水生铬、水生铅、水生砷、水生铜和水生锌；以及 (4) 7 种固体废物，包括工业固体废物、塑料薄膜、农作物秸秆、动物粪便、污泥、医疗废物和生活垃圾。根据现有数据，2018 年 CEEIO 数据库涵盖了这 44 种环境压力中的 28 种：(1) 各行业燃料燃烧量；(2) 工业产品产量；(3) 农作物产量；(4) 牲畜和家禽数量；(5) 农业、工业和生活淡水消耗量；(6) 塑料薄膜使用量。

数据来源、处理和代表性
数据选择和组合原则 排放数据覆盖范围：2018年中国环境投入产出扩展（CEEIO）数据库包括26种燃料燃烧产生的排放，以及各种工业生产过程中产生的二氧化碳、甲烷和氮氧化物等19种大气污染物的排放。 工业过程包括：包括原油、植物油、纸张和几种化学品在内的多种产品的生产过程中产生的排放。 历史排放量调整：对于最后可用数据来自 2015 年的污染物，2018 年的估算是通过应用特定行业的价格指数，并根据国家权威来源的综合排放量数据进行调整得出的。
偏离数据选择和组合原则/解释 None
数据处理和外推原则 历史排放量调整：对于最后可用数据来自 2015 年的污染物，2017 年的估算是通过应用特定行业的价格指数，并根据国家权威来源的综合排放量数据进行调整得出的。 淡水消耗量估算：各行业的淡水使用量是通过将该行业的产出与其供水比例联系起来得出的，并将总量与报告的国家消耗量数字保持一致。 固体废物和排放估算方法：通过将相关服务部门的产出与其废物强度相关联，并辅以家庭废物预测的人口数据，得出污泥和医疗废物的预测结果。 农业废弃物计算：塑料薄膜、农作物秸秆和牲畜粪便废弃物的量化涉及将使用率和废弃物产生指标应用于农业产量和牲畜数量。 部门分类统一：部门分类的转换确保了不同标准之间的数据兼容性，二进制矩阵说明了当前数据库和以前数据库中部门之间的关系。 单位：货币单位由 "10000 元 "调整为 "1 元"，重量单位由 "吨 "调整为 "公斤"。
