Carbon dioxide (CO) emissions from China's cement production process have increased rapidly in recent decades, comprising the second-largest source of CO emissions in the country, next only to fossil fuel combustion. However, there used to lack high-quality data to estimate provincial process-related CO emissions from the cement industry of China. It has been recognised that many previous publications have adopted cement-based accounting methods or national average emission factors to estimate them. This study assembles fundamental provincial clinker production data and provincial clinker emission factors from multiple official statistics sources, following the Intergovernmental Panel on Climate Change (IPCC) methodology (A clinker-based estimation methodology), to develop a high-quality panel dataset of China's provincial process-related cement emissions during 1993-2019. In 2019, the gross cement process emissions of China amounted to 818.2 Mt CO, and the cumulative emissions between 1993-2019 were estimated to be approximately 12.5 Gt CO. There are significant differences in provincial process-related CO emissions. The dataset is crucial to provincial cement process emission characterisation and emissions reduction policy-making in China.
中国水泥生产过程中的二氧化碳(CO)排放量在近几十年内迅速增加,已成为该国第二大 CO 排放源,仅次于化石燃料燃烧。然而,过去缺乏高质量的数据来估算中国水泥行业的省级工艺相关 CO 排放量。人们已经认识到,许多以前的出版物都采用基于水泥的核算方法或国家平均排放因子来估算这些排放量。本研究采用政府间气候变化专门委员会(IPCC)方法(基于熟料的估算方法),从多个官方统计来源中汇总了基本的省级熟料生产数据和省级熟料排放因子,以开发高质量的中国省级工艺相关水泥排放数据集。在 1993-2019 年期间。2019 年,中国水泥工艺总排放量达到 8.182 亿吨 CO,1993-2019 年期间的累计排放量约为 125 亿吨 CO。省级工艺相关 CO 排放量存在显著差异。该数据集对于中国省级水泥工艺排放特征描述和减排政策制定至关重要。
