摘要

随着快速的城市化以及对新建筑和基础设施的需求,中国的水泥产量预计将增加。与此同时,由于水泥生产是能源密集度最高的行业之一,中国与水泥行业相关的能源消耗和碳排放预计将增加。按照政府的目标和措施,引入新的、更相关的、管理更好的技术,可以提高能源效率,减少碳排放。然而,水泥行业的许多挑战和不确定性都得到了解决,而没有考虑工业、能源、建筑和服务等部门之间的几个相互关联的过程,这导致该行业几乎没有改善。Nexus方法被认为是同时检查具有不同元素的多个部门之间相互作用的有效方法。本研究旨在通过综合评估能力,为未来能源-水泥-碳排放关系提供见解,与中国2050年的新型城镇化规划相关。若干挑战和不确定性,包括人口增长的不同趋势、经济驱动力的结构性转变,以及资源利用效率和环境生产的新的但更严格的政策目标,被置于多种情景中。我们的分析结果提供了对未来方向的展望,以强调能源、水泥和碳排放之间日益增长的相互联系,并为促进综合规划、管理和治理制定了明确而具体的路线图。

Energy-Cement-Carbon Emission Nexus and its Implications for Future Urbanization in China
With rapid urbanization and the requirements for new buildings and infrastructure, cement production is expected to increase in China. Meanwhile, China’s energy consumption and carbon emissions associated with cement industry are expected to increase, as cement production is one of the most energy intensive industries. Introducing new and more pertinent technologies with better management, as indicated by government goals and measures, can improve energy efficiency and reduce carbon emission. However, many challenges and uncertainties in the cement industry have been addressed without considering several interconnected processes among sectors including industry, energy, construction, and services, which lead to little improvements in the industry. Nexus approaches are recognized as effective methods to simultaneously examine interactions among multiple sectors with various elements. This research intends to provide insights for future energy-cement-carbon emission nexus, through integrated assessment capabilities, related to China’s new urbanization planning toward 2050. Several challenges and uncertainties, including different trends in population growth, structural transformation of economic driving forces, and new but stricter policy targets for resource use efficiency and environment production, are put into multiple scenarios. The results of our analysis provide perspectives on future direction to underscore the growing interconnection among energy, cement and carbon emission with clear and more specific roadmap for promoting integrated planning, management and governance.
