水泥行业是中国第二大能源消耗行业，也是二氧化碳和空气污染物的主要排放行业。它占中国能源消耗总量的7%，排放总量中二氧化碳、颗粒物、二氧化硫和氮氧化物的排放量分别占15%、21%、4%和10%。中国水泥行业能源消耗、二氧化碳和空气污染物排放的省际差异很少被量化。本研究开发了一个综合评估模型，包括省级节能供给曲线（ECSC）（可以显示每个省的成本效益和技术节能潜力）、温室气体和空气污染相互作用与协同（GAINS）模型（可以用于计算空气污染物排放量）和ArcGIS（具有详细空间功能的地理信息系统（GIS）），并用于评估各省在二氧化碳和空气污染物减排方面的节能潜力以及能效措施的多重效益。 2011-2030 年期间省级。结果显示，未来二十年各省在节能潜力以及二氧化碳和空气污染物（即PM、SO2和NOx）减排方面存在显着差异。山东、四川、江苏、广东、浙江、河南、河北等七省（其中六省位于中东部地区）的节能潜力占总节能潜力的47%，相当于2030年基准能源使用量的26%。节能措施可帮助这七省减少38%的CO2、23%的SO2、33%的NOx和26%的PM排放。 2030。这表明当地政策制定者或最终用户在决定是否采用能效措施解决环境问题时应考虑多重效益。
China’s cement industry is the second largest energy consumer and key emitter of CO2and air pollutants. It accounts for 7% of total energy consumption in China and 15% of CO2, 21% of PM, 4% SO2and 10% of NOx of total emissions, respectively. Provincial disparities in energy consumption and emissions of CO2and air pollutants in China’s cement industry are rarely quantified. In this study, an integrated assessment model including provincial energy conservation supply curves (ECSC) (which can shows the cost-effective and technical energy saving potential per province), the Greenhouse Gas and Air Pollution Interactions and Synergies (GAINS) model (which can be used to calculate air pollutant emissions), and ArcGIS (a geographical information system (GIS) with elaborated spatial functions) is developed and used to assess the potential of energy savings in terms of emission mitigation of CO2and air pollutants and multiple benefits of energy efficiency measures at the provincial level during the period 2011–2030. The results show significant heterogeneity across provinces in terms of potential of energy saving as well as emission mitigation of CO2and air pollutants (i.e. PM, SO2, and NOx) in the next two decades. Seven provinces (i.e. Shandong, Sichuan, Jiangsu, Guangdong, Zhejiang, Henan, Hebei), six of which are located in the central- and east-China, account for 47% of the total energy saving potential, equivalent to 26% of baseline energy use in 2030. The energy efficiency measures can help decrease 38% of CO2, 23% of SO2, 33% of NOx, and 26% of PM emissions in these seven provinces by 2030. This indicates that the multiple benefits should be considered when local policy makers or end users make decisions whether to use energy efficiency measures to solve environmental issues.
