A dataset of carbon emissions from coal mining in coal resource cities in China

Coal is often regarded as the most polluting energy source, contributing significantly to greenhouse gas emissions and air pollution at every stage, from mining to utilization. While carbon emissions during coal use have traditionally been the primary focus of the industry, emissions from the production phase, at the forefront of the supply chain, are often overlooked. Estimating carbon dioxide emissions from coal production is crucial for guiding the sustainable use of coal resources in China. This study employs a top-down modeling approach across the entire energy system, utilizing energy carbon emission factors (EF) to assess CO2 emissions from coal mining activities in various resource-dependent cities in China. The findings reveal that cities with the highest carbon emissions from coal mining are chiefly located in Shaanxi and Inner Mongolia within the Jin-Shan-Mongolia-Ningxia-Gansu region, as well as Hebei, Shandong, and Anhui provinces in the eastern region, and Chongqing, Guizhou, and Yunnan provinces in the southern region.

煤炭常被视作污染性最强的能源，从开采至利用的全流程均会显著加剧温室气体排放与大气污染。尽管传统上煤炭消费环节的碳排放一直是行业关注的核心焦点，但作为供应链前端的煤炭生产阶段的碳排放却常被忽视。估算煤炭生产环节的二氧化碳排放量，对指导我国煤炭资源的可持续利用至关重要。本研究采用覆盖全能源系统的自上而下建模方法，借助能源碳排放因子（Carbon Emission Factor, EF）评估我国各资源依赖型城市的煤炭开采活动所产生的二氧化碳排放量。研究结果显示，煤炭开采碳排放规模最高的城市主要分布于晋陕蒙甘宁区域的陕西与内蒙古境内，东部地区的河北、山东、安徽三省，以及南部地区的重庆、贵州与云南各省市。
